[Check_mk (english)] R: Re: Triggering a script on a remote server

Hi Matt,

You can do this with “local checks”, performed by the agent.

What you need to do is:

Place the script in the directory monitored by the Check MK agent, you can find it with “cmk -d ” run on the Check
MK server.

You need to play with the output provided by the script, it doesn’t work with a simple exit code and the output you want.

All the details on how to create the expected output can be found here:

Hi,

I know you can trigger a script on the CMK server via notifications. However, I want CMK to trigger a script on a remote server via the client on
a remote server that is being monitored.

Is this possible? What am I missing?

I am using version 1.2.6p12

Thanks!

Hi,

I certainly appreciate the replies! But I guess I wasn’t very clear, or I am still not understanding.

My goal is to trigger a script on a monitored server via CMK, based off an already configured check. Not create a remote script to create a check
in CMK.

For example,

·
Setup a basic active website check
à “Check HTTP Service” , call it “ApacheWebPage”

·
“ApacheWebPage” check is now configured and green for server “x” httpd service.

·
“ApacheWebPage” check moves to red for server “x”. (The website is down)

·
CMK notifications can trigger a local script in the “/omd/sites//local/share/check_mk/notifications/” directory off of this check.

Can you trigger a script locally on server “x” using the agent on server “x”.

I am currently prototyping a method to use CMK notifications to trigger a script that remotely starts services on server “x”, unattended.

It would be a heck of a lot easier if the agent just allowed you to trigger a remote script, or command, like “systemctl restart httpd.service”
for the example above. Especially for a windows server. I am thinking of using ansible to do those…but a canned solution would be awesome.

Thanks!

-Matt

I’m curious about this myself. Something tells me this would happen somewhere off of the ‘Notifications’ workflow. Having thought about this (I’d love to hear feedback from the CMK devs), it feels like it could happen via a Notification Method plugin in Notifications. For example, you have a Pagerduty, SMS, ASCII text and other ‘methods’. There’s no reason why someone couldn’t write a ‘run this command’ on ‘this host’ type ‘plugin’ (if it’s even called a plugin). I’m curious what’s involved at that, and if there’s any documentation somewhere that exposes that possibility. Taking a look at the Pagerduty plugin as an example, I see it run a script out of $OMD_ROOT/local/share/check_mk/notifications, which takes the parameters specified in WATO. It’s got everything you’d need in terms of variables being passed to a script.

I’m probably oversimplifying, but I’m curious if there’s any documentation out there for custom notification methods. “Remote Run” would be kind of cool to have as a Notification Method.

That said, there’s some documentation out there for some of that extensible behavior, except for the event console config. https://mathias-kettner.de/checkmk_mkeventd_actions.html . Maybe if all the notifications went to Event Console ("Send notifications to Event Console in Global Settings in WATO) were enabled, it wouldn’t be so hard. I haven’t tested that yet.

I can’t think of another clean way. You probably don’t want the check_mk_agent script local to the host doing anything that isn’t really idempotent, and it’s not its job anyway to run scripts that make system changes, so that’s out. One could configure standard e-mail alerts using ASCII, to an e-mail box where a postfix or some utility parses the inbound e-mails and then runs whatever script you want, but that’ll be disjointed from the Check_MK instance.

The caveat is it's for Enterprise edition and also only available in version 1.4 on, so maybe not going to fit for you.

So alert handlers look to be available in CRE 1.4.0b3 version. I downloaded it and setup a new site, and it appears it is a part of it.

       Any idea when the stable version will be released? This is exciting. I might even be able get money to buy the enterprise edition with that option...

       What is the significance between the CEE 1.4.0i3p1 and CRE 1.4.0b3 version? or beta vs innovation?

       Thanks!
       -Matt

       Hi Matthew
       http://mathias-kettner.com/cms_alert_handlers.htmlhttp://mathias-kettner.com/cms_alert_handlers.html - see Section 8 at the end which seems to describe what you are looking for.

       The caveat is it's for Enterprise edition and also only available in version 1.4 on, so maybe not going to fit for you.

       I'm curious about this myself. Something tells me this would happen somewhere off of the 'Notifications' workflow. Having thought about this (I'd love to hear feedback from the CMK devs), it feels like it could happen via a Notification Method plugin in Notifications. For example, you have a Pagerduty, SMS, ASCII text and other 'methods'. There's no reason why someone couldn't write a 'run this command' on 'this host' type 'plugin' (if it's even called a plugin). I'm curious what's involved at that, and if there's any documentation somewhere that exposes that possibility. Taking a look at the Pagerduty plugin as an example, I see it run a script out of $OMD_ROOT/local/share/check_mk/notifications, which takes the parameters specified in WATO. It's got everything you'd need in terms of variables being passed to a script.

       I'm probably oversimplifying, but I'm curious if there's any documentation out there for custom notification methods. "Remote Run" would be kind of cool to have as a Notification Method.

       That said, there's some documentation out there for some of that extensible behavior, except for the event console config. https://mathias-kettner.de/checkmk_mkeventd_actions.html . Maybe if all the notifications went to Event Console ("Send notifications to Event Console in Global Settings in WATO) were enabled, it wouldn't be so hard. I haven't tested that yet.

       I can't think of another clean way. You probably don't want the check_mk_agent script local to the host doing anything that isn't really idempotent, and it's not its job anyway to run scripts that make system changes, so that's out. One could configure standard e-mail alerts using ASCII, to an e-mail box where a postfix or some utility parses the inbound e-mails and then runs whatever script you want, but that'll be disjointed from the Check_MK instance.

       Hi,
                       I certainly appreciate the replies! But I guess I wasn't very clear, or I am still not understanding.

                       My goal is to trigger a script on a monitored server via CMK, based off an already configured check. Not create a remote script to create a check in CMK.

                       For example,

       . Setup a basic active website check --> "Check HTTP Service" , call it "ApacheWebPage"

       . "ApacheWebPage" check is now configured and green for server "x" httpd service.

       . "ApacheWebPage" check moves to red for server "x". (The website is down)

       . CMK notifications can trigger a local script in the "/omd/sites/<site>/local/share/check_mk/notifications/" directory off of this check.
       Can you trigger a script locally on server "x" using the agent on server "x".

       I am currently prototyping a method to use CMK notifications to trigger a script that remotely starts services on server "x", unattended.
       It would be a heck of a lot easier if the agent just allowed you to trigger a remote script, or command, like "systemctl restart httpd.service" for the example above. Especially for a windows server. I am thinking of using ansible to do those.but a canned solution would be awesome.

       Thanks!

       Ogg: Re: [Check_mk (english)] Triggering a script on a remote server Hi Matt, You can do this with "local checks", performed by the agent.
       What you need to do is:

       1) Place the script in the directory monitored by the Check MK agent, you can find it with "cmk -d <host>" run on the Check MK server.

       2) You need to play with the output provided by the script, it doesn't work with a simple exit code and the output you want.

       All the details on how to create the expected output can be found here:

       Hi,
       I know you can trigger a script on the CMK server via notifications. However, I want CMK to trigger a script on a remote server via the client on a remote server that is being monitored.
               Is this possible? What am I missing?
               I am using version 1.2.6p12
       Thanks!

Hi Matt,

The german version of the ‘Check_MK Versions’ page has a good write-up on the meaning of the check_mk release cycle. For some reason, the english version is out of date, but Google translate does a fine job.

https://mathias-kettner.de/cms_cmk_versionen.html

In short, the beta is feature complete to the next stable version. Innovation versions are available to paying customers and are short-term supported versions forked off of the development branch, so they can be behind the beta in terms of features. CEE and CRE are different in other ways, including the inclusion of the Micro-core in CEE.
