Telegraf service on windows 11 only send partially data, works if executed manually

Hi, I am pretty new to Telegraf/InfluxDB/Grafana and I am getting into it using my own PC, so I am pretty new to this. I gather some information and report it into Influx to build a dashboard.

Telegraf is running as a service and reporting some data including a [[input.exec]] plugin with a ps1 script.

.\telegraf.exe --service install --config ‘C:\Program Files\InfluxData\telegraf\telegraf-1.23.4\telegraf.conf’

The script contains WMI data and is reporting some of the data but not all. I can see the script is executed by telegraf and running once a second.

The strange thing is that telegraf is sending all data from the script if running manually:

.\telegraf.exe --config ‘C:\Program Files\InfluxData\telegraf\telegraf-1.23.4\telegraf.conf’

is is not when running as a service. There is only a single ps1 script that is used so I assume it is not a permission challenge.

How can I best debug this behavior ?

Script part that only works manually:

## Custom stuff here

$ohmf = 'c:\Program Files\InfluxData\telegraf\telegraf-1.23.4\exe\ohm.txt'
$ohm = Get-CimInstance -ClassName Sensor -Namespace 'root\OpenHardwareMonitor' > $ohmf

$cpupcvalue=$cpupc.split(":",5)[-1] -replace '\s','' -replace ',','.'

# GPU Core temp: /atigpu/0/temperature/0
$gputemp=Select-String $ohmf -Pattern "/atigpu/0/temperature/0" -Context 0,10 | out-string -stream | select -first 1 -skip 10

$gpuhotspot=Select-String $ohmf -Pattern "/atigpu/0/temperature/9" -Context 0,10 | out-string -stream | select -first 1 -skip 10
$gpuhotspotvalue=$gpuhotspot.split(":",5)[-1] -replace '\s','' -replace ',','.'

# GPU power: /atigpu/0/power/0
$gpupower=Select-String $ohmf -Pattern "/atigpu/0/power/0" -Context 0,10 | out-string -stream | select -first 1 -skip 10

echo "$($metric),host=$($si.Name),metric=cpucd value=$($cpuccdvalue)"
echo "$($metric),host=$($si.Name),metric=cpupower value=$($cpupowervalue)"
echo "$($metric),host=$($si.Name),metric=cpupc value=$($cpupcvalue)"

That’s the first thing I’d check…
When it runs manually it’s using your user… but which user is running the service? does it have proper permission? (the easiest way is to impersonate it)

It is running as System but I switched to my account to test it without success. Also I would be surprised if a single ps1 is having “partially” permission issues. All information are collected from WMI using Get-CimInstance.

Also the output script “ohm.txt” is populated with correct and new information every second when the service is running so the script is executed and all metrics are gathered and written correctly on the local disk but not into the InfluxDB instance.

Can you share your input and output config then?
I’d expect some output errors tho.

Here is what a test gives me.

Is there any good way to get output from telegraf when running as a service ? I cannot find any log / output and the “logfile” option in telegraf.conf always gives me a syntax error.

PS C:\Program Files\InfluxData\telegraf\telegraf-1.23.4>

see logtarget and logfile here

put the path in single quotes to avoid escaping errors, also the user must have permission to write the specified log file

okay, so the service collects a different value as telegraf.exe when running as a user. This is why I do not get the full response.

Will have a look why I get a different result running the same code as a service and from user space.

.\telegraf.exe --service install --service-name telegraf-2 --config ‘C:\Program Files\InfluxData\telegraf\telegraf-1.23.4\telegraf_custom.conf’
