Hi folks, UCS maniacs!
After one of update in July 2020 nagios service doesn’t up. The problem was like this:
Running pre-flight check on configuration data... Checking objects... Error: Service check command 'check_univention_ad_connector' specified in service 'UNIVENTION_ADCONNECTOR' for host 'dcb.mydomain' not defined anywhere! Checked 37 services. Checked 2 hosts. Checked 1 host groups. Checked 0 service groups. Checked 1 contacts. Checked 2 contact groups. Checked 191 commands. Checked 4 time periods. Checked 0 host escalations. Checked 0 service escalations. Checking for circular paths... Checked 2 hosts Checked 0 service dependencies Checked 0 host dependencies Checked 4 timeperiods Checking global event handlers... Checking obsessive compulsive processor commands... Checking misc settings... Total Warnings: 0 Total Errors: 1 ***> One or more problems was encountered while running the pre-flight check...
When I removed host from UMC->Devices->Nagios->UNIVENTION_ADCONNECTOR proccess goes up and all is green in my nagios panel.
Why that happened? What is UNIVENTION_ADCONNECTOR for? Is it OK to deactivate it by this way?
Thanks in advance
