win_perf_counters readme

This document presents the input plugin to read Performance Counters on Windows operating systems.

The configuration is parsed and then tested for validity, such as whether the Object, Instance and Counter exist on Telegraf startup.

Counter paths are refreshed periodically, see the CountersRefreshInterval configuration parameter for more info.

In case of query for all instances ["*"], the plugin does not return the instance _Total by default. See IncludeTotal for more info.

Basics

The examples contained in this file have been found on the internet as counters used when performance monitoring Active Directory and IIS in particular. There are a lot of other good objects to monitor, if you know what to look for. This file is likely to be updated in the future with more examples for useful configurations for separate scenarios.

Plugin wide

Plugin wide entries are underneath [[inputs.win_perf_counters]].

PrintValid

Bool, if set to true will print out all matching performance objects.

Example: PrintValid=true

UseWildcardsExpansion

If UseWildcardsExpansion is set to true, wildcards can be used in the instance name and the counter name. When using localized Windows, counters will be also be localized. Instance indexes will also be returned in the instance name.

Partial wildcards (e.g. chrome*) are supported only in the instance name on Windows Vista and newer.

If disabled, wildcards (not partial) in instance names can still be used, but instance indexes will not be returned in the instance names.

Example: UseWildcardsExpansion=true

CountersRefreshInterval

Configured counters are matched against available counters at the interval specified by the CountersRefreshInterval parameter. The default value is 1m (1 minute).

If wildcards are used in instance or counter names, they are expanded at this point, if the UseWildcardsExpansion param is set to true.

Setting the CountersRefreshInterval too low (order of seconds) can cause Telegraf to create a high CPU load.

Set it to 0s to disable periodic refreshing.

Example: CountersRefreshInterval=1m

PreVistaSupport

Deprecated. Necessary features on Windows Vista and newer are checked dynamically

Bool, if set to true, the plugin will use the localized PerfCounter interface that has been present since before Vista for backwards compatability.

It is recommended NOT to use this on OSes starting with Vista and newer because it requires more configuration to use this than the newer interface present since Vista.

Example for Windows Server 2003, this would be set to true: PreVistaSupport=true

UsePerfCounterTime

Bool, if set to true will request a timestamp along with the PerfCounter data. If se to false, current time will be used.

Supported on Windows Vista/Windows Server 2008 and newer Example: UsePerfCounterTime=true

Object

See Entry below.

Entry

A new configuration entry consists of the TOML header starting with, [[inputs.win_perf_counters.object]]. This must follow before other plugin configurations, beneath the main win_perf_counters entry, [[inputs.win_perf_counters]].

Following this are 3 required key/value pairs and three optional parameters and their usage.

ObjectName

Required

ObjectName is the Object to query for, like Processor, DirectoryServices, LogicalDisk or similar.

Example: ObjectName = "LogicalDisk"

Instances

Required

The instances key (this is an array) declares the instances of a counter you would like returned, it can be one or more values.

Example: Instances = ["C:","D:","E:"]

This will return only for the instances C:, D: and E: where relevant. To get all instances of a Counter, use ["*"] only. By default any results containing _Total are stripped, unless this is specified as the wanted instance. Alternatively see the option IncludeTotal below.

It is also possible to set partial wildcards, eg. ["chrome*"], if the UseWildcardsExpansion param is set to true

Some Objects do not have instances to select from at all. Here only one option is valid if you want data back, and that is to specify Instances = ["------"].

Counters

Required

The Counters key (this is an array) declares the counters of the ObjectName you would like returned, it can also be one or more values.

Example: Counters = ["% Idle Time", "% Disk Read Time", "% Disk Write Time"]

This must be specified for every counter you want the results of, or use ["*"] for all the counters of the object, if the UseWildcardsExpansion param is set to true.

Measurement

Optional

This key is optional. If it is not set it will be win_perf_counters. In InfluxDB this is the key underneath which the returned data is stored. So for ordering your data in a good manner, this is a good key to set with a value when you want your IIS and Disk results stored separately from Processor results.

Example: `Measurement = "win_disk"``

IncludeTotal

Optional

This key is optional. It is a simple bool. If it is not set to true or included it is treated as false. This key only has effect if the Instances key is set to ["*"] and you would also like all instances containing _Total to be returned, like _Total, 0,_Total and so on where applicable (Processor Information is one example).

WarnOnMissing

Optional

This key is optional. It is a simple bool. If it is not set to true or included it is treated as false. This only has effect on the first execution of the plugin. It will print out any ObjectName/Instance/Counter combinations asked for that do not match. Useful when debugging new configurations.

FailOnMissing

Internal

This key should not be used. It is for testing purposes only. It is a simple bool. If it is not set to true or included this is treated as false. If this is set to true, the plugin will abort and end prematurely if any of the combinations of ObjectName/Instances/Counters are invalid.

Troubleshooting

If you are getting an error about an invalid counter, use the typeperf command to check the counter path on the command line. E.g. typeperf "Process(chrome*)\% Processor Time"

If no metrics are emitted even with the default config, you may need to repair your performance counters.

  1. Launch the Command Prompt as Administrator (right click Runs As Administrator).
  2. Drop into the C:\WINDOWS\System32 directory by typing C: then cd \Windows\System32
  3. Rebuild your counter values, which may take a few moments so please be patient, by running: 
    lodctr /r
