+When there are multiple processes with the same name, WMI represents those after the first instance as `process-name#index`.

See [process](docs/collector.process.md) for more information.

+
+## Useful queries
+
+### Buffer Cache Hit Ratio
+
+When you read the counter in perfmon you will get the the percentage pages found in the buffer cache. This percentage is calculated internally based on the total number of cache hits divided by the total number of cache lookups over the last few thousand page accesses.
+This collector retrieves the two internal values separately. In order to calculate the Buffer Cache Hit Ratio in PromQL.
+
+```
+windows_mssql_bufman_buffer_cache_hits{instance="host:9182", exported_instance="MSSQLSERVER"} /
+windows_mssql_bufman_buffer_cache_lookups{instance="host:9182", exported_instance="MSSQLSERVER"}
+```
+
+This principal can be used for following metrics too:
+- AccessMethodsWorktablesFromCacheHitRatio
+  - accessmethods_worktables_from_cache_hits
+  - accessmethods_worktables_from_cache_lookups
+- LogCacheHitRatio
+  - databases_log_cache_hits

+
+A WMI filter on which services to include. Recommended to keep down number of returned metrics.
+
+Example: `--collector.service.services-where="Name='windows_exporter'"`
+
+## Metrics
+
+Name | Description | Type | Labels
+-----|-------------|------|-------
+`windows_service_info` | Contains service information in labels, constant 1 | gauge | name, display_name, process_id
+`windows_service_state` | The state of the service, 1 if the current state, 0 otherwise | gauge | name, state
+`windows_service_start_mode` | The start mode of the service, 1 if the current start mode, 0 otherwise | gauge | name, start_mode
+`windows_service_status` | The status of the service, 1 if the current status, 0 otherwise | gauge | name, status
+
+For the values of the `state`, `start_mode` and `status` labels, see below.
+
+### States
+
+A service can be in the following states:
+- `stopped`
+- `start pending`
+- `stop pending`
+- `running`
+- `continue pending`
+- `pause pending`
+- `paused`
+- `unknown`
+
+### Start modes
+
+A service can have the following start modes:
+- `boot`
+- `system`
+- `auto`
+- `manual`
+- `disabled`
+
+### Status
+
+A service can have any of the following statuses:
+- `ok`
+- `error`
+- `degraded`
+- `unknown`
+- `pred fail`
+- `starting`
+- `stopping`
+- `service`
+- `stressed`
+- `nonrecover`
+- `no contact`
+- `lost comm`
+
+Note that there is some overlap with service state.
+
+### Example metric
+Lists the services that have a 'disabled' start mode.
+```
+windows_service_start_mode{exported_name=~"(mssqlserver|sqlserveragent)",start_mode="disabled"}
+```
+
+## Useful queries
+Counts the number of Microsoft SQL Server/Agent Processes
+```
+count(windows_service_state{exported_name=~"(sqlserveragent|mssqlserver)",state="running"})
+```
+
+## Alerting examples
+**prometheus.rules**
+```yaml
+groups:
+- name: Microsoft SQL Server Alerts
+  rules:
+
+  # Sends an alert when the 'sqlserveragent' service is not in the running state for 3 minutes.
+  - alert: SQL Server Agent DOWN
+    expr: windows_service_state{instance="SQL",exported_name="sqlserveragent",state="running"} == 0
+    for: 3m
+    labels:
+      severity: high
+    annotations:
+      summary: "Service {{ $labels.exported_name }} down"
+      description: "Service {{ $labels.exported_name }} on instance {{ $labels.instance }} has been down for more than 3 minutes."

+      summary: "Service {{ $labels.exported_name }} down"
+      description: "Service {{ $labels.exported_name }} on instance {{ $labels.instance }} has been down for more than 3 minutes."
+```
+In this example, `instance` is the target label of the host. So each alert will be processed per host, which is then used in the alert description.

+`windows_terminal_services_handle_count` | Total number of handles currently opened by this process. This number is the sum of the handles currently opened by each thread in this process. | gauge | `session_name`
+`windows_terminal_services_page_fault_total` | Rate at which page faults occur in the threads executing in this process. A page fault occurs when a thread refers to a virtual memory page that is not in its working set in main memory. The page may not be retrieved from disk if it is on the standby list and therefore already in main memory. The page also may not be retrieved if it is in use by another process which shares the page. | counter | `session_name`
+`windows_terminal_services_page_file_bytes` | Current number of bytes this process has used in the paging file(s). Paging files are used to store pages of memory used by the process that are not contained in other files. Paging files are shared by all processes, and lack of space in paging files can prevent other processes from allocating memory. | gauge | `session_name`
+`windows_terminal_services_page_file_bytes_peak` | Maximum number of bytes this process has used in the paging file(s). Paging files are used to store pages of memory used by the process that are not contained in other files. Paging files are shared by all processes, and lack of space in paging files can prevent other processes from allocating memory. | gauge | `session_name`

+`windows_terminal_services_pool_non_paged_bytes` | Number of bytes in the non-paged pool, an area of system memory (physical memory used by the operating system) for objects that cannot be written to disk, but must remain in physical memory as long as they are allocated. This property displays the last observed value only; it is not an average. | gauge | `session_name`

This property displays the last observed value only; it is not an average. | gauge | `session_name`
+`windows_terminal_services_private_bytes` | Current number of bytes this process has allocated that cannot be shared with other processes. | gauge | `session_name`
+`windows_terminal_services_thread_count` | Number of threads currently active in this process. An instruction is the basic unit of execution in a processor, and a thread is the object that executes instructions. Every running process has at least one thread. | gauge | `session_name`
+`windows_terminal_services_virtual_bytes` | Current size, in bytes, of the virtual address space the process is using. Use of virtual address space does not necessarily imply corresponding use of either disk or main memory pages. Virtual space is finite and, by using too much, the process can limit its ability to load libraries. | gauge | `session_name`

Use of virtual address space does not necessarily imply corresponding use of either disk or main memory pages. Virtual space is finite and, by using too much, the process might limit its ability to load libraries. | gauge | `session_name`
+`windows_terminal_services_working_set_bytes` | Current number of bytes in the working set of this process. The working set is the set of memory pages touched recently by the threads in the process. If free memory in the computer is above a threshold, pages are left in the working set of a process even if they are not in use. When free memory falls below a threshold, pages are trimmed from working sets. If they are needed, they are then soft-faulted back into the working set before they leave main memory. | gauge | `session_name`
+`windows_terminal_services_working_set_bytes_peak` | Maximum number of bytes in the working set of this process at any point in time. The working set is the set of memory pages touched recently by the threads in the process. If free memory in the computer is above a threshold, pages are left in the working set of a process even if they are not in use.

-Package template implements data-driven templates for generating textual output.
-
-To generate HTML output, see package html/template, which has the same interface
-as this package but automatically secures HTML output against certain attacks.
-
-Templates are executed by applying them to a data structure. Annotations in the
-template refer to elements of the data structure (typically a field of a struct
-or a key in a map) to control execution and derive values to be displayed.
-Execution of the template walks the structure and sets the cursor, represented
-by a period '.' and called "dot", to the value at the current location in the
-structure as execution proceeds.
-
-The input text for a template is UTF-8-encoded text in any format.
-"Actions"--data evaluations or control structures--are delimited by
-"{{" and "}}"; all text outside actions is copied to the output unchanged.
-Actions may not span newlines, although comments can.
-
-Once parsed, a template may be executed safely in parallel.
-
-Here is a trivial example that prints "17 items are made of wool".
-
-	type Inventory struct {
-		Material string
-		Count    uint
-	}
-	sweaters := Inventory{"wool", 17}
-	tmpl, err := template.New("test").Parse("{{.Count}} items are made of {{.Material}}")
-	if err != nil { panic(err) }
-	err = tmpl.Execute(os.Stdout, sweaters)
-	if err != nil { panic(err) }
-
-More intricate examples appear below.
-
-Actions
-
-Here is the list of actions. "Arguments" and "pipelines" are evaluations of
-data, defined in detail below.
-
-*/
-//	{{/* a comment */}}
-//		A comment; discarded. May contain newlines.
-//		Comments do not nest and must start and end at the
-//		delimiters, as shown here.
-/*
-
-	{{pipeline}}
-		The default textual representation of the value of the pipeline
-		is copied to the output.
-
-	{{if pipeline}} T1 {{end}}
-		If the value of the pipeline is empty, no output is generated;
-		otherwise, T1 is executed.  The empty values are false, 0, any
-		nil pointer or interface value, and any array, slice, map, or
-		string of length zero.
-		Dot is unaffected.
-
-	{{if pipeline}} T1 {{else}} T0 {{end}}
-		If the value of the pipeline is empty, T0 is executed;
-		otherwise, T1 is executed.  Dot is unaffected.
-
-	{{if pipeline}} T1 {{else if pipeline}} T0 {{end}}
-		To simplify the appearance of if-else chains, the else action
-		of an if may include another if directly; the effect is exactly
-		the same as writing
-			{{if pipeline}} T1 {{else}}{{if pipeline}} T0 {{end}}{{end}}
-
-	{{range pipeline}} T1 {{end}}
-		The value of the pipeline must be an array, slice, map, or channel.
-		If the value of the pipeline has length zero, nothing is output;
-		otherwise, dot is set to the successive elements of the array,
-		slice, or map and T1 is executed. If the value is a map and the
-		keys are of basic type with a defined order ("comparable"), the
-		elements will be visited in sorted key order.
-
-	{{range pipeline}} T1 {{else}} T0 {{end}}
-		The value of the pipeline must be an array, slice, map, or channel.
-		If the value of the pipeline has length zero, dot is unaffected and
-		T0 is executed; otherwise, dot is set to the successive elements
-		of the array, slice, or map and T1 is executed.
-
-	{{template "name"}}
-		The template with the specified name is executed with nil data.
-
-	{{template "name" pipeline}}
-		The template with the specified name is executed with dot set
-		to the value of the pipeline.
-
-	{{with pipeline}} T1 {{end}}
-		If the value of the pipeline is empty, no output is generated;
-		otherwise, dot is set to the value of the pipeline and T1 is
-		executed.
-
-	{{with pipeline}} T1 {{else}} T0 {{end}}
-		If the value of the pipeline is empty, dot is unaffected and T0
-		is executed; otherwise, dot is set to the value of the pipeline
-		and T1 is executed.
-
-Arguments
-
-An argument is a simple value, denoted by one of the following.
-
-	- A boolean, string, character, integer, floating-point, imaginary
-	  or complex constant in Go syntax. These behave like Go's untyped
-	  constants, although raw strings may not span newlines.
-	- The keyword nil, representing an untyped Go nil.
-	- The character '.' (period):
-		.
-	  The result is the value of dot.
-	- A variable name, which is a (possibly empty) alphanumeric string
-	  preceded by a dollar sign, such as
-		$piOver2
-	  or
-		$
-	  The result is the value of the variable.
-	  Variables are described below.
-	- The name of a field of the data, which must be a struct, preceded
-	  by a period, such as
-		.Field
-	  The result is the value of the field. Field invocations may be
-	  chained:
-	    .Field1.Field2
-	  Fields can also be evaluated on variables, including chaining:
-	    $x.Field1.Field2
-	- The name of a key of the data, which must be a map, preceded
-	  by a period, such as
-		.Key
-	  The result is the map element value indexed by the key.
-	  Key invocations may be chained and combined with fields to any
-	  depth:
-	    .Field1.Key1.Field2.Key2
-	  Although the key must be an alphanumeric identifier, unlike with
-	  field names they do not need to start with an upper case letter.
-	  Keys can also be evaluated on variables, including chaining:
-	    $x.key1.key2
-	- The name of a niladic method of the data, preceded by a period,
-	  such as
-		.Method
-	  The result is the value of invoking the method with dot as the
-	  receiver, dot.Method(). Such a method must have one return value (of
-	  any type) or two return values, the second of which is an error.
-	  If it has two and the returned error is non-nil, execution terminates
-	  and an error is returned to the caller as the value of Execute.
-	  Method invocations may be chained and combined with fields and keys
-	  to any depth:
-	    .Field1.Key1.Method1.Field2.Key2.Method2
-	  Methods can also be evaluated on variables, including chaining:
-	    $x.Method1.Field
-	- The name of a niladic function, such as
-		fun
-	  The result is the value of invoking the function, fun(). The return
-	  types and values behave as in methods. Functions and function
-	  names are described below.
-	- A parenthesized instance of one the above, for grouping. The result
-	  may be accessed by a field or map key invocation.
-		print (.F1 arg1) (.F2 arg2)
-		(.StructValuedMethod "arg").Field
-
-Arguments may evaluate to any type; if they are pointers the implementation
-automatically indirects to the base type when required.
-If an evaluation yields a function value, such as a function-valued
-field of a struct, the function is not invoked automatically, but it
-can be used as a truth value for an if action and the like. To invoke
-it, use the call function, defined below.
-
-A pipeline is a possibly chained sequence of "commands". A command is a simple
-value (argument) or a function or method call, possibly with multiple arguments:
-
-	Argument
-		The result is the value of evaluating the argument.
-	.Method [Argument...]
-		The method can be alone or the last element of a chain but,
-		unlike methods in the middle of a chain, it can take arguments.
-		The result is the value of calling the method with the
-		arguments:
-			dot.Method(Argument1, etc.)
-	functionName [Argument...]
-		The result is the value of calling the function associated
-		with the name:
-			function(Argument1, etc.)
-		Functions and function names are described below.
-
-Pipelines
-
-A pipeline may be "chained" by separating a sequence of commands with pipeline
-characters '|'. In a chained pipeline, the result of the each command is
-passed as the last argument of the following command. The output of the final
-command in the pipeline is the value of the pipeline.
-
-The output of a command will be either one value or two values, the second of
-which has type error. If that second value is present and evaluates to
-non-nil, execution terminates and the error is returned to the caller of
-Execute.
-
-Variables
-
-A pipeline inside an action may initialize a variable to capture the result.
-The initialization has syntax
-
-	$variable := pipeline
-
-where $variable is the name of the variable. An action that declares a
-variable produces no output.
-
-If a "range" action initializes a variable, the variable is set to the
-successive elements of the iteration.  Also, a "range" may declare two
-variables, separated by a comma:
-
-	range $index, $element := pipeline
-
-in which case $index and $element are set to the successive values of the
-array/slice index or map key and element, respectively.  Note that if there is
-only one variable, it is assigned the element; this is opposite to the
-convention in Go range clauses.
-
-A variable's scope extends to the "end" action of the control structure ("if",
-"with", or "range") in which it is declared, or to the end of the template if
-there is no such control structure.  A template invocation does not inherit
-variables from the point of its invocation.
-
-When execution begins, $ is set to the data argument passed to Execute, that is,
-to the starting value of dot.
-
-Examples
-
-Here are some example one-line templates demonstrating pipelines and variables.
-All produce the quoted word "output":
-
-	{{"\"output\""}}
-		A string constant.
-	{{`"output"`}}
-		A raw string constant.
-	{{printf "%q" "output"}}
-		A function call.
-	{{"output" | printf "%q"}}
-		A function call whose final argument comes from the previous
-		command.
-	{{printf "%q" (print "out" "put")}}
-		A parenthesized argument.
-	{{"put" | printf "%s%s" "out" | printf "%q"}}
-		A more elaborate call.
-	{{"output" | printf "%s" | printf "%q"}}
-		A longer chain.
-	{{with "output"}}{{printf "%q" .}}{{end}}
-		A with action using dot.
-	{{with $x := "output" | printf "%q"}}{{$x}}{{end}}
-		A with action that creates and uses a variable.
-	{{with $x := "output"}}{{printf "%q" $x}}{{end}}
-		A with action that uses the variable in another action.
-	{{with $x := "output"}}{{$x | printf "%q"}}{{end}}
-		The same, but pipelined.
-
-Functions
-
-During execution functions are found in two function maps: first in the
-template, then in the global function map. By default, no functions are defined
-in the template but the Funcs method can be used to add them.
-
-Predefined global functions are named as follows.
-
-	and
-		Returns the boolean AND of its arguments by returning the
-		first empty argument or the last argument, that is,
-		"and x y" behaves as "if x then y else x". All the
-		arguments are evaluated.
-	call
-		Returns the result of calling the first argument, which
-		must be a function, with the remaining arguments as parameters.
-		Thus "call .X.Y 1 2" is, in Go notation, dot.X.Y(1, 2) where
-		Y is a func-valued field, map entry, or the like.
-		The first argument must be the result of an evaluation
-		that yields a value of function type (as distinct from
-		a predefined function such as print). The function must
-		return either one or two result values, the second of which
-		is of type error. If the arguments don't match the function
-		or the returned error value is non-nil, execution stops.
-	html
-		Returns the escaped HTML equivalent of the textual
-		representation of its arguments.
-	index
-		Returns the result of indexing its first argument by the
-		following arguments. Thus "index x 1 2 3" is, in Go syntax,
-		x[1][2][3]. Each indexed item must be a map, slice, or array.
-	js
-		Returns the escaped JavaScript equivalent of the textual
-		representation of its arguments.
-	len
-		Returns the integer length of its argument.
-	not
-		Returns the boolean negation of its single argument.
-	or
-		Returns the boolean OR of its arguments by returning the
-		first non-empty argument or the last argument, that is,
-		"or x y" behaves as "if x then x else y". All the
-		arguments are evaluated.
-	print
-		An alias for fmt.Sprint
-	printf
-		An alias for fmt.Sprintf
-	println
-		An alias for fmt.Sprintln
-	urlquery
-		Returns the escaped value of the textual representation of
-		its arguments in a form suitable for embedding in a URL query.
-
-The boolean functions take any zero value to be false and a non-zero
-value to be true.
-
-There is also a set of binary comparison operators defined as
-functions:
-
-	eq
-		Returns the boolean truth of arg1 == arg2
-	ne
-		Returns the boolean truth of arg1 != arg2
-	lt
-		Returns the boolean truth of arg1 < arg2
-	le
-		Returns the boolean truth of arg1 <= arg2
-	gt
-		Returns the boolean truth of arg1 > arg2
-	ge
-		Returns the boolean truth of arg1 >= arg2
-
-For simpler multi-way equality tests, eq (only) accepts two or more
-arguments and compares the second and subsequent to the first,
-returning in effect
-
-	arg1==arg2 || arg1==arg3 || arg1==arg4 ...
-
-(Unlike with || in Go, however, eq is a function call and all the
-arguments will be evaluated.)
-
-The comparison functions work on basic types only (or named basic
-types, such as "type Celsius float32"). They implement the Go rules
-for comparison of values, except that size and exact type are
-ignored, so any integer value, signed or unsigned, may be compared
-with any other integer value. (The arithmetic value is compared,
-not the bit pattern, so all negative integers are less than all
-unsigned integers.) However, as usual, one may not compare an int
-with a float32 and so on.
-
-Associated templates
-
-Each template is named by a string specified when it is created. Also, each
-template is associated with zero or more other templates that it may invoke by
-name; such associations are transitive and form a name space of templates.
-
-A template may use a template invocation to instantiate another associated
-template; see the explanation of the "template" action above. The name must be
-that of a template associated with the template that contains the invocation.
-
-Nested template definitions
-
-When parsing a template, another template may be defined and associated with the
-template being parsed. Template definitions must appear at the top level of the
-template, much like global variables in a Go program.
-
-The syntax of such definitions is to surround each template declaration with a
-"define" and "end" action.
-
-The define action names the template being created by providing a string
-constant. Here is a simple example:
-
-	`{{define "T1"}}ONE{{end}}
-	{{define "T2"}}TWO{{end}}
-	{{define "T3"}}{{template "T1"}} {{template "T2"}}{{end}}
-	{{template "T3"}}`
-
-This defines two templates, T1 and T2, and a third T3 that invokes the other two
-when it is executed. Finally it invokes T3. If executed this template will
-produce the text
-
-	ONE TWO
-
-By construction, a template may reside in only one association. If it's
-necessary to have a template addressable from multiple associations, the
-template definition must be parsed multiple times to create distinct *Template
-values, or must be copied with the Clone or AddParseTree method.
-
-Parse may be called multiple times to assemble the various associated templates;
-see the ParseFiles and ParseGlob functions and methods for simple ways to parse
-related templates stored in files.
-
-A template may be executed directly or through ExecuteTemplate, which executes
-an associated template identified by name. To invoke our example above, we
-might write,
-
-	err := tmpl.Execute(os.Stdout, "no data needed")
-	if err != nil {
-		log.Fatalf("execution failed: %s", err)
-	}
-
-or to invoke a particular template explicitly by name,
-
-	err := tmpl.ExecuteTemplate(os.Stdout, "T2", "no data needed")
-	if err != nil {
-		log.Fatalf("execution failed: %s", err)
-	}
