 ## Installation
+The latest release can be downloaded from the [releases page](https://github.com/martinlindhe/wmi_exporter/releases).
+
 Each release provides a .msi installer. The installer will setup the WMI Exporter as a Windows service, as well as create an exception in the Windows Firewall.
 
 If the installer is run without any parameters, the exporter will run with default settings for enabled collectors, ports, etc. The following parameters are available:
 
 Name | Description
 -----|------------
-`ENABLED_COLLECTORS` | As the `-collectors.enabled` flag, provide a comma-separated list of enabled collectors
+`ENABLED_COLLECTORS` | As the `--collectors.enabled` flag, provide a comma-separated list of enabled collectors
 `LISTEN_ADDR` | The IP address to bind to. Defaults to 0.0.0.0
 `LISTEN_PORT` | The port to bind to. Defaults to 9182.
 `METRICS_PATH` | The path at which to serve metrics. Defaults to `/metrics`
+`TEXTFILE_DIR` | As the `--collector.textfile.directory` flag, provide a directory to read text files with metrics from
+`EXTRA_FLAGS` | Allows passing full CLI flags. Defaults to an empty string.
 
-Parameters are sent to the installer via `msiexec`. Example invocation:
+Parameters are sent to the installer via `msiexec`. Example invocations:
 
 ```powershell
 msiexec /i <path-to-msi-file> ENABLED_COLLECTORS=os,iis LISTEN_PORT=5000
 ```
 
+Example service collector with a custom query.
+```powershell
+msiexec /i <path-to-msi-file> ENABLED_COLLECTORS=os,service --% EXTRA_FLAGS="--collector.service.services-where ""Name LIKE 'sql%'"""
+```
+
+On some older versions of Windows you may need to surround parameter values with double quotes to get the install command parsing properly:
+```powershell
+msiexec /i C:\Users\Administrator\Downloads\wmi_exporter.msi ENABLED_COLLECTORS="ad,iis,logon,memory,process,tcp,thermalzone" TEXTFILE_DIR="C:\custom_metrics\"
+```

 ## Usage
 
-    go get -u github.com/kardianos/govendor
+    go get -u github.com/prometheus/promu
     go get -u github.com/martinlindhe/wmi_exporter
     cd $env:GOPATH/src/github.com/martinlindhe/wmi_exporter
-    govendor build +local
+    promu build -v .
     .\wmi_exporter.exe
 
 The prometheus metrics will be exposed on [localhost:9182](http://localhost:9182)
 
+## Examples
+
+### Enable only service collector and specify a custom query
+
+    .\wmi_exporter.exe --collectors.enabled "service" --collector.service.services-where "Name='wmi_exporter'"
+
+### Enable only process collector and specify a custom query
+
+    .\wmi_exporter.exe --collectors.enabled "process" --collector.process.processes-where "Name LIKE 'firefox%'"
+
+When there are multiple processes with the same name, WMI represents those after the first instance as `process-name#index`. So to get them all, rather than just the first one, the query needs to be a wildcard search using a `%` character.
+
+Please note that in Windows batch scripts (and when using the `cmd` command prompt), the `%` character is reserved, so it has to be escaped with another `%`. For example, the wildcard syntax for searching for all firefox processes is `firefox%%`.

+### 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.
+
+```
+wmi_mssql_bufman_buffer_cache_hits{instance="host:9182", exported_instance="MSSQLSERVER"} / 
+wmi_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

+### `--collector.service.services-where`
+
+A WMI filter on which services to include. Recommended to keep down number of returned metrics.
+
+Example: `--collector.service.services-where="Name='wmi_exporter'"`
+
+## Metrics
+
+Name | Description | Type | Labels
+-----|-------------|------|-------
+`wmi_service_state` | The state of the service, 1 if the current state, 0 otherwise | gauge | name, state
+`wmi_service_start_mode` | The start mode of the service, 1 if the current start mode, 0 otherwise | gauge | name, start_mode
+`wmi_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.
+```
+wmi_service_start_mode{exported_name=~"(mssqlserver|sqlserveragent)",start_mode="disabled"}
+```
+
+## Useful queries
+Counts the number of Microsoft SQL Server/Agent Processes
+```
+count(wmi_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: wmi_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."
+      
+  # Sends an alert when the 'mssqlserver' service is not in the running state for 3 minutes. 
+  - alert: SQL Server DOWN
+    expr: wmi_service_state{instance="SQL",exported_name="mssqlserver",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."
+```
+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.

-
-Logrus is a structured logger for Go (golang), completely API compatible with
-the standard library logger. [Godoc][godoc]. **Please note the Logrus API is not
-yet stable (pre 1.0). Logrus itself is completely stable and has been used in
-many large deployments. The core API is unlikely to change much but please
-version control your Logrus to make sure you aren't fetching latest `master` on
-every build.**
-
-Nicely color-coded in development (when a TTY is attached, otherwise just
-plain text):
-
-![Colored](http://i.imgur.com/PY7qMwd.png)
-
-With `log.SetFormatter(&log.JSONFormatter{})`, for easy parsing by logstash
-or Splunk:
-
-```json
-{"animal":"walrus","level":"info","msg":"A group of walrus emerges from the
-ocean","size":10,"time":"2014-03-10 19:57:38.562264131 -0400 EDT"}
-
-{"level":"warning","msg":"The group's number increased tremendously!",
-"number":122,"omg":true,"time":"2014-03-10 19:57:38.562471297 -0400 EDT"}
-
-{"animal":"walrus","level":"info","msg":"A giant walrus appears!",
-"size":10,"time":"2014-03-10 19:57:38.562500591 -0400 EDT"}
-
-{"animal":"walrus","level":"info","msg":"Tremendously sized cow enters the ocean.",
-"size":9,"time":"2014-03-10 19:57:38.562527896 -0400 EDT"}
-
-{"level":"fatal","msg":"The ice breaks!","number":100,"omg":true,
-"time":"2014-03-10 19:57:38.562543128 -0400 EDT"}
-```
-
-With the default `log.SetFormatter(&log.TextFormatter{})` when a TTY is not
-attached, the output is compatible with the
-[logfmt](http://godoc.org/github.com/kr/logfmt) format:
-
-```text

-exit status 1
-```
-
-#### Example
-
-The simplest way to use Logrus is simply the package-level exported logger:
-
-```go
-package main
-
-import (
-  log "github.com/Sirupsen/logrus"
-)
-
-func main() {
-  log.WithFields(log.Fields{
-    "animal": "walrus",
-  }).Info("A walrus appears")
-}
-```
-
-Note that it's completely api-compatible with the stdlib logger, so you can
-replace your `log` imports everywhere with `log "github.com/Sirupsen/logrus"`
-and you'll now have the flexibility of Logrus. You can customize it all you
-want:
-
-```go
-package main
-
-import (
-  "os"
-  log "github.com/Sirupsen/logrus"
-)
-
-func init() {
-  // Log as JSON instead of the default ASCII formatter.
-  log.SetFormatter(&log.JSONFormatter{})
-
-  // Output to stderr instead of stdout, could also be a file.
-  log.SetOutput(os.Stderr)
-
-  // Only log the warning severity or above.
-  log.SetLevel(log.WarnLevel)
-}
-
-func main() {
-  log.WithFields(log.Fields{
-    "animal": "walrus",
-    "size":   10,
-  }).Info("A group of walrus emerges from the ocean")
-
-  log.WithFields(log.Fields{
-    "omg":    true,
-    "number": 122,
-  }).Warn("The group's number increased tremendously!")
-
-  log.WithFields(log.Fields{
-    "omg":    true,
-    "number": 100,
-  }).Fatal("The ice breaks!")
-
-  // A common pattern is to re-use fields between logging statements by re-using
-  // the logrus.Entry returned from WithFields()
-  contextLogger := log.WithFields(log.Fields{
-    "common": "this is a common field",
-    "other": "I also should be logged always",
-  })
-
-  contextLogger.Info("I'll be logged with common and other field")
-  contextLogger.Info("Me too")
-}
-```
-
-For more advanced usage such as logging to multiple locations from the same
-application, you can also create an instance of the `logrus` Logger:
-
-```go
-package main
-
-import (
-  "github.com/Sirupsen/logrus"
-)
-
-// Create a new instance of the logger. You can have any number of instances.
-var log = logrus.New()
-
-func main() {
-  // The API for setting attributes is a little different than the package level
-  // exported logger. See Godoc.
-  log.Out = os.Stderr
-
-  log.WithFields(logrus.Fields{
-    "animal": "walrus",
-    "size":   10,
-  }).Info("A group of walrus emerges from the ocean")
-}
-```
-
-#### Fields
-
-Logrus encourages careful, structured logging though logging fields instead of
-long, unparseable error messages. For example, instead of: `log.Fatalf("Failed
-to send event %s to topic %s with key %d")`, you should log the much more
-discoverable:
-
-```go
-log.WithFields(log.Fields{
-  "event": event,
-  "topic": topic,
-  "key": key,
-}).Fatal("Failed to send event")
-```
-
-We've found this API forces you to think about logging in a way that produces
-much more useful logging messages. We've been in countless situations where just
-a single added field to a log statement that was already there would've saved us
-hours. The `WithFields` call is optional.
-
-In general, with Logrus using any of the `printf`-family functions should be
-seen as a hint you should add a field, however, you can still use the
-`printf`-family functions with Logrus.
-
-#### Hooks
-
-You can add hooks for logging levels. For example to send errors to an exception
-tracking service on `Error`, `Fatal` and `Panic`, info to StatsD or log to
-multiple places simultaneously, e.g. syslog.
-
-Logrus comes with [built-in hooks](hooks/). Add those, or your custom hook, in
-`init`:
-
-```go
-import (
-  log "github.com/Sirupsen/logrus"
-  "gopkg.in/gemnasium/logrus-airbrake-hook.v2" // the package is named "aibrake"
-  logrus_syslog "github.com/Sirupsen/logrus/hooks/syslog"
-  "log/syslog"
-)
-
-func init() {
-
-  // Use the Airbrake hook to report errors that have Error severity or above to
-  // an exception tracker. You can create custom hooks, see the Hooks section.
-  log.AddHook(airbrake.NewHook(123, "xyz", "production"))
-
-  hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "")
-  if err != nil {
-    log.Error("Unable to connect to local syslog daemon")
-  } else {
-    log.AddHook(hook)
-  }
-}
-```
-Note: Syslog hook also support connecting to local syslog (Ex. "/dev/log" or "/var/run/syslog" or "/var/run/log"). For the detail, please check the [syslog hook README](hooks/syslog/README.md).

-
-#### Level logging
-
-Logrus has six logging levels: Debug, Info, Warning, Error, Fatal and Panic.
-
-```go
-log.Debug("Useful debugging information.")
-log.Info("Something noteworthy happened!")
-log.Warn("You should probably take a look at this.")
-log.Error("Something failed but I'm not quitting.")
-// Calls os.Exit(1) after logging
-log.Fatal("Bye.")
-// Calls panic() after logging
-log.Panic("I'm bailing.")
-```
-
-You can set the logging level on a `Logger`, then it will only log entries with
-that severity or anything above it:
-
-```go
-// Will log anything that is info or above (warn, error, fatal, panic). Default.
-log.SetLevel(log.InfoLevel)
-```
-
-It may be useful to set `log.Level = logrus.DebugLevel` in a debug or verbose
-environment if your application has that.
-
-#### Entries
-
-Besides the fields added with `WithField` or `WithFields` some fields are
-automatically added to all logging events:
-
-1. `time`. The timestamp when the entry was created.
-2. `msg`. The logging message passed to `{Info,Warn,Error,Fatal,Panic}` after
-   the `AddFields` call. E.g. `Failed to send event.`
-3. `level`. The logging level. E.g. `info`.
-
-#### Environments
-
-Logrus has no notion of environment.
-
-If you wish for hooks and formatters to only be used in specific environments,
-you should handle that yourself. For example, if your application has a global
-variable `Environment`, which is a string representation of the environment you
-could do:
-
-```go
-import (
-  log "github.com/Sirupsen/logrus"
-)
-
-init() {
-  // do something here to set environment depending on an environment variable
-  // or command-line flag
-  if Environment == "production" {
-    log.SetFormatter(&log.JSONFormatter{})
-  } else {
-    // The TextFormatter is default, you don't actually have to do this.
-    log.SetFormatter(&log.TextFormatter{})
-  }
-}
-```
-
-This configuration is how `logrus` was intended to be used, but JSON in
-production is mostly only useful if you do log aggregation with tools like
-Splunk or Logstash.
-
-#### Formatters
-
-The built-in logging formatters are:
-
-* `logrus.TextFormatter`. Logs the event in colors if stdout is a tty, otherwise
-  without colors.
-  * *Note:* to force colored output when there is no TTY, set the `ForceColors`
-    field to `true`.  To force no colored output even if there is a TTY  set the
-    `DisableColors` field to `true`
-* `logrus.JSONFormatter`. Logs fields as JSON.
-
-Third party logging formatters:
-
-* [`logstash`](https://github.com/bshuster-repo/logrus-logstash-hook). Logs fields as [Logstash](http://logstash.net) Events.
-* [`prefixed`](https://github.com/x-cray/logrus-prefixed-formatter). Displays log entry source along with alternative layout.
-* [`zalgo`](https://github.com/aybabtme/logzalgo). Invoking the P͉̫o̳̼̊w̖͈̰͎e̬͔̭͂r͚̼̹̲ ̫͓͉̳͈ō̠͕͖̚f̝͍̠ ͕̲̞͖͑Z̖̫̤̫ͪa͉̬͈̗l͖͎g̳̥o̰̥̅!̣͔̲̻͊̄ ̙̘̦̹̦.
-
-You can define your formatter by implementing the `Formatter` interface,
-requiring a `Format` method. `Format` takes an `*Entry`. `entry.Data` is a
-`Fields` type (`map[string]interface{}`) with all your fields as well as the
-default ones (see Entries section above):
-
-```go
-type MyJSONFormatter struct {
-}
-
-log.SetFormatter(new(MyJSONFormatter))
-
-func (f *MyJSONFormatter) Format(entry *Entry) ([]byte, error) {
-  // Note this doesn't include Time, Level and Message which are available on
-  // the Entry. Consult `godoc` on information about those fields or read the
-  // source of the official loggers.
-  serialized, err := json.Marshal(entry.Data)
-    if err != nil {
-      return nil, fmt.Errorf("Failed to marshal fields to JSON, %v", err)
-    }
-  return append(serialized, '\n'), nil
-}
-```
-
-#### Logger as an `io.Writer`
-
-Logrus can be transformed into an `io.Writer`. That writer is the end of an `io.Pipe` and it is your responsibility to close it.
-
-```go
-w := logger.Writer()
-defer w.Close()
-
-srv := http.Server{
-    // create a stdlib log.Logger that writes to
-    // logrus.Logger.
-    ErrorLog: log.New(w, "", 0),
-}
-```
-
-Each line written to that writer will be printed the usual way, using formatters
-and hooks. The level for those entries is `info`.
-
-#### Rotation
-
-Log rotation is not provided with Logrus. Log rotation should be done by an
-external program (like `logrotate(8)`) that can compress and delete old log
-entries. It should not be a feature of the application-level logger.
-
-#### Tools
-
-| Tool | Description |
-| ---- | ----------- |
-|[Logrus Mate](https://github.com/gogap/logrus_mate)|Logrus mate is a tool for Logrus to manage loggers, you can initial logger's level, hook and formatter by config file, the logger will generated with different config at different environment.|
-
-#### Testing
-
-Logrus has a built in facility for asserting the presence of log messages. This is implemented through the `test` hook and provides:
-
-* decorators for existing logger (`test.NewLocal` and `test.NewGlobal`) which basically just add the `test` hook
-* a test logger (`test.NewNullLogger`) that just records log messages (and does not output any):
-
-```go
-logger, hook := NewNullLogger()
-logger.Error("Hello error")
-
-assert.Equal(1, len(hook.Entries))
-assert.Equal(logrus.ErrorLevel, hook.LastEntry().Level)
-assert.Equal("Hello error", hook.LastEntry().Message)
-
-hook.Reset()
-assert.Nil(hook.LastEntry())
-```
-
-#### Fatal handlers
-
-Logrus can register one or more functions that will be called when any `fatal`
-level message is logged. The registered handlers will be executed before
-logrus performs a `os.Exit(1)`. This behavior may be helpful if callers need
-to gracefully shutdown. Unlike a `panic("Something went wrong...")` call which can be intercepted with a deferred `recover` a call to `os.Exit(1)` can not be intercepted.
-
-```
-...
-handler := func() {
-  // gracefully shutdown something...
-}
-logrus.RegisterExitHandler(handler)
-...
-```
-
-#### Thread safty
-
-By default Logger is protected by mutex for concurrent writes, this mutex is invoked when calling hooks and writing logs.
-If you are sure such locking is not needed, you can call logger.SetNoLock() to disable the locking.
-
-Situation when locking is not needed includes:
-
-* You have no hooks registered, or hooks calling is already thread-safe.
-
-* Writing to logger.Out is already thread-safe, for example:
-
-  1) logger.Out is protected by locks.
-
-  2) logger.Out is a os.File handler opened with `O_APPEND` flag, and every write is smaller than 4k. (This allow multi-thread/multi-process writing)
