Good afternoon.
I made a very simple local check to see if security updates are required on linux hosts and gave it a 10 minute interval between checks.
In the official documentation,
it is stated that:
“They will then only be executed according to a defined interval, buffered, and then this cache will be appended to the agent’s output.”
Is it possible to remove this information from the output?
Thank you.
You can touch -d 1970-01-01 the cache file in /var/lib/check_mk_agent/cache if you want to trigger the execution of the plugin.
Which Linux distribution? Debian/Ubuntu? Then you could just use the official mk_apt agent plugin which does just that.
Also see share/doc/check_mk/treasures/mk_apt_hook for an example hook file that resets the cache timestamp just as r.sander suggested. If you copy this to /etc/apt/apt.conf.d/98mk-apt, then it will automatically execute the touch command in a “Post-Invoke” hook after dpkg has run, e.g. after installing updates.
I am using CentOs 6/7 and Oracle Linux
I am not sure I explained myself currectly.
This is my output:
I want to remove the “OK - Cache generated 166 s ago, cache interval: 10 m, elapsed cache lifespan: 27.77%” part of the output, if possible.
I also saw the YUM plug in, but I am not quite sure it gives me what I want.
Our custom plugin is very simple and gives us the detailed information we required. I will have a test machine soon with a security package required to compare both outputs.
Hey - have you fixed it?
I have some plugins as well with different times. I don’t want to remove the lines at the end:
Cache generated 6 minutes 22 seconds ago, cache interval: 1 hour 0 minutes, elapsed cache lifespan: 10.61%
And I don’t want to have my output
No, I did not try to fix it.
I got moved to another project, and since this was a minor detail I did not bother removing it.
I found a solution:
If you use the local folder there’s no Cache. If you create a folder like 120 (for two minutes) you have a cache.
If you use the plugins folder with 120, the cache is in the output (like <<local:cached(1630064295,3600)>>) but not in the Check result. So you have only the result without the cached information.
You need to add “echo “<<>>”” to the Output - then the plugin is detected by CheckMK
You need to add “echo “<<>>”” to the Output - then the plugin is detected by CheckMK
Where do i have to add this? Does it work with powershell scripts?
until recently it was working with <nnoCacheOutput at the end of line. But after a update it doesn’t work anymore.
For Linux:
echo "<<<local>>>"
echo "0 'Test Check' OK"
For Windows
Write-host "<<<local>>>"
Write-host 0 '"Test Check"' - OK
