Error creating runner from config: can not convert 'object' into 'string' accessing 'diskio.include_devices.0'

Hello,

As I noticed a lot of

”Could not return any performance counter values for \.\Y: .Error: Incorrect function.”

For the diskio dataset, I tried setting:

But this results in:

Error creating runner from config: can not convert 'object' into 'string' accessing 'diskio.include_devices.0'

After which there are no more diskio metrics at all.

Hello @willemdh

We see below error message in the log if we use C: , D: as part of the include disks.

Unit state changed system/metrics-default-system/metrics-system-9e6d7bd9-3dba-435f-9cc3-a17f41799bdf (STARTING->FAILED): can not convert 'object' into 'string' accessing 'diskio.include_devices.0

Below is the documentation :

System diskio metricset | Beats

For the Windows you can use the processor as shown below which will only pick records for D: & drop other records as it seems we cannot specify the drive as part of devices.

Thanks!!
