Seeing this error in the infra agent logs while the vri-perfmon is running

any guidance you can provide would be greatly appreciated.

Did you build a custom counter file? This error indicates it had trouble parsing it:

Unhandled Exception: Newtonsoft.Json.JsonSerializationException: Unexpected end when deserializing array. Path 'counterlist[0]', line 11, position 1.

If so, can you attach your config file?

[stevescott34]

Hi here is the config file which I assume is the default one. thanks for the quick response

config.zip

Hmm, that is the default one, line 11 doesn't look any different from the others, so I'm not sure what's going on here. Let's run down a checklist:

• The file you just provided, did you copy it from the host where nri-perfmon is running?
• Did you install the latest version from here? https://github.com/newrelic/nri-perfmon/releases/latest
• When you installed it, did you unzip it on the host where you were installing?
• Did you customize anything at all in nri-perfmon?
• What version of Windows is this and what version of .NET Framework is installed on that host?

I re-installed both the new relic infra agent and the perfmon integration and all appears to be fine now. I can see the data in New Relic now. I suspect it was something hanging around from a previous attempt to deploy.

Thanks again for the help and for the quick responses !

Let's consider this ticket closed

No problem, glad it worked out!
