How to monitor Windows performance on Zabbix

Background Information

I've been rereading some books about Windows performance recently. For a lazy person like me who used to use SCOM monitoring, the Windows OS template that comes with Zabbix is ​​really not enough, because the previous SCOM monitoring package (published by Microsoft, did all the work, and I only needed to enable rules and alarms as needed).

The default Zabbix performance data only has Avg Latency, and the average data is not accurate. If you want to see the latency and IOPS of the disk, you have to do it yourself. After looking at the syntax of windows performance counter in zabbix, I backed off a little. The CounterCategory and CounterName of all numeric performance counters.

The only statistics related to the built-in disk are the transfer speed and average latency.

Windows Performance Monitoring on Zabbix

If there are other performance counters to monitor, what are their names and what do they do? Is there a list that can be searched quickly?

Solve it

Fortunately, PowerShell is easy to write, so I wrote the following function, which integrates the syntax of Zabbix's performance counters.

function Get-PerfCounterDesc{
 [cmdletbinding()]
 param(
  [switch]$show
 )

 $Categories = [System.Diagnostics.PerformanceCounterCategory]::GetCategories()
 $SingleInstanceCategories = $Categories | Where-Object {$_.CategoryType -eq "SingleInstance"} 
 $MultiInstanceCategories = $Categories| Where-Object {$_.CategoryType -eq "MultiInstance"}

 $SingleInstanceCounters = $SingleInstanceCategories | ForEach-Object {
  (new-object System.Diagnostics.PerformanceCounterCategory($_.CategoryName)).GetCounters() 
 }
 $MultiInstanceCounters = $MultiInstanceCategories | ForEach-Object {
  $category = new-object System.Diagnostics.PerformanceCounterCategory($_.CategoryName)
  if($category.InstanceExists('_Total')){
   $category.GetCounters('_Total') 
  }elseif($category.InstanceExists('Total')){
   $category.GetCounters('Total')
  }else{
   $instanceNames = $category.GetInstanceNames()
   if($instanceNames.count -gt 0){
    $category.GetCounters($instanceNames[0])
   }
  }
 }

 $AllCounters = $MultiInstanceCounters + $SingleInstanceCounters 
 $key="HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\009"

 $counters=Get-ItemPropertyValue -Path $key -Name "counter"
 $Dict=@{}

 for ($i=0;$i -lt $counters.count;$i=$i+2){
  if($counters[$i+1] -and -not $Dict.ContainsKey($counters[$i+1])){
   $Dict.add($counters[$i+1],$counters[$i])
  }
 }
 Write-Debug $dict.keys.count
 $result=$AllCounters | Sort-Object Categoryname,Countername|
   Select-Object CategoryName,
   Countername,
   @{n="zabbixPerfCounter";e={'perf_counter["\{0}({{#ReplaceThis}})\{1}"]' -f $dict[$_.CategoryName],$dict[$_.Countername]}},
   @{n="categoryNum";e={$Dict[$_.CategoryName]}},
   @{n="CounterNum";e={$Dict[$_.Countername]}},
   CategoryHelp,
   CounterHelp

 if($show){
  $result|Out-GridView
 }else{
  $result
 }
}

How to use it? Add the above function directly to your personal PowerShell profile, that is, in the PowerShell console notepad $profile , paste the content in, save it, and then set set-executionpolicy remotesigned to allow custom unsigned scripts to run.

Start a new PowerShell and type Get-PerfCounterDesc -show directly. You can filter the results in various ways. The zabbixPerfCounter column is the key used on the generated zabbix. Please replace {#replaceThis} with the instance name of the counter. For example, _total.

Then I added the following counters in the zabbix template to display the disk IOPS and Latency

You also need to change Grafana accordingly
