Too Long; Didn't Read
We use <a href="https://mathias-kettner.com/index.html" target="_blank">OMD/Check_MK</a> to monitor our IT infrastructure. It is easy to use and we always know the status of our network components, <a href="https://openschoolsolutions.org/shutdown-servers-case-power-failure%e2%80%8a-%e2%80%8aups-nut-co/" target="_blank">servers</a>, printers, etc. Until now we used the “old-stable” version (1.2.8), but the CPU usage increased significantly, so it was time to upgrade to the current stable version (1.4.0). Today I want to show you how to update Check_MK and what to consider.
