IcingaCheckPerfCounter - ThresholdInterval not working properly?

[DeHook]

Hi,
we tested the IcingaCheckPerfCounter Powershell Check and we want to use the ThresholdInterval option for average values of the last x minutes.

We installed the icingapowershell Service on the Server and registered the Check.

When we open the performance monitor and run the check simultaniously, the average values will not fit.

I don't know where our mistake is and where we can change the query.

The Check-query is Invoke-IcingaCheckPerfCounter -PerfCounter '\processor(0)\% processor time' -ThresholdInterval 1m

Thank you.

Hello

Thank you for the issue. Could you please share the configuration of the Invoke-IcingaCheckPerfCounter check?

You can fetch them with

Show-IcingaRegisteredServiceChecks

According to the plugin output you provided, the interval values are not present, because otherwise the time interval would be added there, like

processor0_processor_time_1

Thank you for your reply.

Here the configuration of the Invoke-IcingaCheckPerfCounter - Check:

Thank you.

Ah, I see, You are missing the arguments. You need to add the arguments as well, otherwise the check does not know, what do to.

1. Use the Id of the Service to remove it with Unregister-IcingaServiceCheck $id
2. Register the check again

Register-IcingaServiceCheck -CheckCommand Invoke-IcingaCheckPerfCounter -Arguments @{ '-PerfCounter' = '\processor(0)\% processor time'; } -TimeIndexes 1, 2, 3, 5 -Interval 30;

Please check if I added all your time indexes. Once done, restart the PowerShell daemon with

Restart-Service icingapowershell

and after a short time, this should work properly.

Ok, I was reading the official documentation. There ist just a part about the checkCPU part without arguments. That makes sense. I unregistered the first check, registered it again with the arguments an restarted the icingapowershell.

But it is not working properly:

I tested it with 1m, 2m & 2.
The output is still processor(0)_processor_time.

Thank you.

Can you please test the linked PR if this resolves the issue?

For testing:

1. Stop the background daemon service
2. Update the Framework
3. Remove the Invoke-IcingaCheckPerfCounter json files within the cache folder for both, checkresult and checkresult_store
4. Restart the background daemon service
5. Wait for the files to be written on your disk in the folder
6. Execute the plugin again within a new PowerShell session

After that, it should work. I will add this fix to v1.5.1 if you report back successfully.

Thank you again!

I have a few questions.
We updated the two files in the lib folder. We reviewed registered checks and restarted the icingapowershell service. This looks OK.
We are waiting for the cache files more than 60 minutes and they aren't created yet. I don't know what we did wrong or why the cache files aren't there now.

The -ThresholdInterval-parameter will not be automatically detected in the powershell console when I begin to write the parameter and use the tabulator. Is this normal for this check?

[LordHepipud]

Is the background daemon registered? You can check this with

Get-IcingaBackgroundDaemons

You should see Start-IcingaServiceCheckDaemon inside.

If not, please run

Register-IcingaBackgroundDaemon -Command 'Start-IcingaServiceCheckDaemon';

afterwards restart the PowerShell daemon.

If the daemon is already present, it could be a permission problem. Are you running the Icinga Agent on the system as well?
In case you do, please make sure the service user for icinga2 and icingapowershell is identical.

Then run

Test-IcingaAgent

to verify that access to the cache directory is granted for this user. If not, the command will give you the required command to set permissions.

Otherwise you will require manually to grant permissions to the cache folder for the user the icingapowershell service is running with.

[DeHook]

Okay, it's working now! Thank you very much.
The Background Daemon were not running and the permissions to the cache folder were not set.

I tested it with a few other counters and it's working fine.

[LordHepipud]

Excellent, thank you very much! Just one important thing:

In case you are using the identical plugin, in this case Invoke-IcingaCheckPerfCounter, please ensure you only register one check command definition and add all required Performance Counters as list to -PerfCounter.

Otherwise they might conflict each other.

Basically your registered service check should cover with processor, memory and even more directly with -PerfCounter.

I will apply the fix directly to v1.5.1.
