This leads to an UNKNOWN-State.

I observed a similar error when timezones on the monitoring server and monitored server are not the same. In that case a few hours later (in my case two hours) the check can be performed without crashing and the state goes back to OK. In that case using the same timezones removed the errors.

After I fixed the timezones the error still occures but a little bit different. It seems as if the real cause is that the check is performed while the task is running. Other tasks on the same server don't enter this state with the same check but enter this state at different times. The task from this example is configured to run every 15 minutes but it doesn't crash every time. The next time the check is running everything is fine again. But in this way I get a few error/recovery messages per hour which is annoying. Clocks of the monitoring server and monitored server seem to be running in sync (by the second).

Release v2.1: If no values for "Maximal time since last run" are set in a given rule the check returns an error.

<AttributeError ('list' object has no attribute 'get')>

This seems to be new or a new option with version 2.1. It took me some time to find out that the cause was that simple so it might be changed or at least the information is helpful to someone updating from an earlier version of this plugin.

I've seen multiple people online asking about this and haven't found "the one" solution yet. Hopefully you can help!

Idea:

• Create a new check / use an existing check for checking the status of a Windows service
• If the service is a required service and it is stopped, try to start the service

Getting the status
This, in theory, could be a bash script that will run on the CheckMK server and executes the following command:

#!/bin/bash
# Getting the status
net rpc service list NAMEOFSERVICE -S HOSTNAME.DOMAIN.LOCAL -U DOMAIN.LOCAL/Username%Password

Starting the service

I believe that restarting the service could be triggered using Alert Handlers, but I'm not sure if that is supported.

The Alert Handler could be a bash script that will run on the CheckMK server and executes the following command:

#!/bin/bash
# Starting of services
net rpc service start NAMEOFSERVICE -S HOSTNAME.DOMAIN.LOCAL -U DOMAIN.LOCAL/Username%Password

Requirements
samba-common package installed on the CheckMK server.
Firewall rule added to allow RPC
New-NetFirewallRule -DisplayName 'RPC (CheckMK)' -Description 'Required for checking and restarting services' -Profile Domain,Private,Public -Direction Inbound -Action Allow -EdgeTraversalPolicy Block -Protocol 'TCP' -LocalPort 'RPC'

If you know a different way to achieve this feel free to share idea's. I'm available for development, testing and documenting.

Sorry if this is not the right place for this request.

Dear jiuka,

we are using your extensionpackage win_scheduled_task v2.2 in our Distributed Installation (1 Master site and 9 Subsites) of checkMK.

I've updated our Distributed Installation from version 2.1.0p28 to 2.2.0p3. During the checkMK update a message came up that the win_scheduled_task package is not supported under checkMK v2.2.0. In the extension manager the package entry shows that wwin_scheduled_task 2.2 supports all checkMK version from 2.0.0 until 2.1.0.

Have you planned to create a new version of win_scheduled_task which supports the newer checkMK versions? Will it be relleases in the checkMK exchange area or here in Github?

Thank you in advance
Ronald Kloust
