 ## Useful queries
-_This collector does not yet have any useful queries added, we would appreciate your help adding them!_
+
+### 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
+  - databases_log_cache_lookups
+- AverageLockWaitTime
+  - locks_wait_time_seconds
+  - locks_count

-# go-winio
-
-This repository contains utilities for efficiently performing Win32 IO operations in
-Go. Currently, this is focused on accessing named pipes and other file handles, and
-for using named pipes as a net transport.
-
-This code relies on IO completion ports to avoid blocking IO on system threads, allowing Go
-to reuse the thread to schedule another goroutine. This limits support to Windows Vista and
-newer operating systems. This is similar to the implementation of network sockets in Go's net
-package.
-
-Please see the LICENSE file for licensing information.
-
-This project has adopted the [Microsoft Open Source Code of
-Conduct](https://opensource.microsoft.com/codeofconduct/). For more information
-see the [Code of Conduct
-FAQ](https://opensource.microsoft.com/codeofconduct/faq/) or contact
-[opencode@microsoft.com](mailto:opencode@microsoft.com) with any additional
-questions or comments.
-
-Thanks to natefinch for the inspiration for this library. See https://github.com/natefinch/npipe
-for another named pipe implementation.

-mksyscall_windows generates windows system call bodies
-
-It parses all files specified on command line containing function
-prototypes (like syscall_windows.go) and prints system call bodies
-to standard output.
-
-The prototypes are marked by lines beginning with "//sys" and read
-like func declarations if //sys is replaced by func, but:
-
-* The parameter lists must give a name for each argument. This
-  includes return parameters.
-
-* The parameter lists must give a type for each argument:
-  the (x, y, z int) shorthand is not allowed.
-
-* If the return parameter is an error number, it must be named err.
-
-* If go func name needs to be different from it's winapi dll name,
-  the winapi name could be specified at the end, after "=" sign, like
-  //sys LoadLibrary(libname string) (handle uint32, err error) = LoadLibraryA
-
-* Each function that returns err needs to supply a condition, that
-  return value of winapi will be tested against to detect failure.
-  This would set err to windows "last-error", otherwise it will be nil.
-  The value can be provided at end of //sys declaration, like
-  //sys LoadLibrary(libname string) (handle uint32, err error) [failretval==-1] = LoadLibraryA
-  and is [failretval==0] by default.
-
-Usage:
-	mksyscall_windows [flags] [path ...]
-
-The flags are:
-	-output
-		Specify output file name (outputs to console if blank).
-	-trace
-		Generate print statement after every syscall.
