[Check_mk (english)] How to restrict check_mk servers to monitor only 2 services

vaibhav_beohar · April 2, 2019, 4:08pm

Hi,

Is there any way can restrict check_mk servers to monitor only availability and root space, i wanted to make some sort of rules, so that while adding server it will look for only 2 services.

I have around 250 Linux server under check_MK monitoring but wanted to restrict the server to look for only two services.

I know it can be done through regex and I did tried but couldn’t get success, here is the step which I have followed.

Create a service group and assign all the host to that particular service group
Went to host and service parameter à grouping,
look for the Assignment
of services to service groups, edit the service group and Specify explicit values, saved and applied the changes.
But it didn’t get reflected in my system.

Could you please help here, thanks.

Hi Vaibhav,

first the question why do you want to do this?
Second the Check_MK system works that way that you get all the data
from a single host with only one query to the host.
That means all the data is collected if you want it or not.
What you can do is to disable all the other check types for these
hosts. Generate a rule to disable all check types for one folder. Put
your hosts there inside and enable only the check types you want.
But i would say that is not like a monitoring system should work

best regards
Andreas

No need to block all that information.

The Linux agent is simply a 'bash' script. Write a replacement, that only returns the information you want.

Install the check_mk_agent package, so the systems is configured, and then overwrite the /usr/bin/check_mk_agent file with your new script.

If the only information your revised agent provides is the data for the root filesystems, it will be the only information in the inventory, and thus the only "service" being monitored.

Hi,

You can achieve this by putting them in the same folder and then create a ‘disabled services’ rule for that folder, and put the required services in the ‘Explicit Services’. Then select negate.

You find the rule in WATO → Host & Service Parameters under
Monitoring Configuration → Inventory and Check_MK Settings → Disabled
Services.

There is also a search function under Host & Service Parameters. Just enter
the search string “disabled”.

Thanks & Regards,

Praveen.
