# win_perf_counters readme
|
||||
|
||||
The way this plugin works is that on load of Telegraf,
|
||||
the plugin will be handed configuration from Telegraf.
|
||||
This configuration is parsed and then tested for validity such as
|
||||
if the Object, Instance and Counter existing.
|
||||
If it does not match at startup, it will not be fetched.
|
||||
Exceptions to this are in cases where you query for all instances "*".
|
||||
By default the plugin does not return _Total
|
||||
when it is querying for all (*) as this is redundant.
|
||||
Input plugin to read Performance Counters on Windows operating systems.
|
||||
|
||||
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 [CountersRefreshInterval](#countersrefreshinterval)
|
||||
configuration parameter for more info.
|
||||
|
||||
Wildcards can be used in instance and counter names. Partial wildcards are supported only
|
||||
in instance names on Windows Vista and newer.
|
||||
|
||||
In case of query for all instances `["*"]`, the plugin does not return the instance `_Total`
|
||||
by default. See [IncludeTotal](#includetotal) for more info.

Example:

`PrintValid=true`
|
||||
|
||||
#### CountersRefreshInterval
|
||||
|
||||
Configured counters are matched against available counters at the interval
|
||||
specified by the `CountersRefreshInterval` parameter. Default value is `1m` (1 minute).
|
||||
|
||||
If wildcards are used in instance or counter names, they are expanded at this point.
|
||||
|
||||
Setting `CountersRefreshInterval` too low (order of seconds) can cause Telegraf to create
|
||||
a high CPU load.

Set to `0s` to disable periodic refreshing.

## 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"`
