Logs from Telegraf

[inputs.win_wmi] Error in plugin: Object server is stopping when OLE service contacts it

System info

Telegraf 1.31.3, 1.32.1 e.g. Windows 2019/2016

Docker

No response

Steps to reproduce

1. Run given telegraf config (query at least two values with [[inputs.win_wmi.method]]
2. Usually after some hours You will see inside Telegraf log ERROR messages "_[inputs.winwmi] Error in plugin: Object server is stopping when OLE service contacts it"
3. When this error occurs, [[inputs.win_wmi.method]] does not successfully query value, so "sValue" is null/empty/

Expected behavior

In case of this error "Object server is stopping when OLE service contacts it" (CO_E_SERVER_STOPPING 0x80080008), Telegraf should retry query until inputs timeout has been reached or try to avoid this error.

Actual behavior

Error occurs and metric is not created.

Hi,

I believe the error is thrown in one of these lines as those are the only ones, which don't get prefixed with some additional error information.

• https://github.com/influxdata/telegraf/blob/master/plugins/inputs/win_wmi/method.go#L81
• https://github.com/influxdata/telegraf/blob/master/plugins/inputs/win_wmi/method.go#L89

Also this error doesn't only affect .method but also .query sections, so there's also these two lines.

• https://github.com/influxdata/telegraf/blob/master/plugins/inputs/win_wmi/query.go#L89
• https://github.com/influxdata/telegraf/blob/master/plugins/inputs/win_wmi/query.go#L96

The Windows-Error which is thrown by those functions is CO_E_SERVER_STOPPING, which unfortunately doesn't really point to a specific function. Also, the documentation doesn't recommend a specific handling, so I don't really know how to fix that or even what causes this.
