Dear CheckMK community,
I am new to checkMK. I have tried installing the raw edition (2.1) on CentOS 7, 8 and 9. The graphs for attached switch (using snmp) and localhost (in hosts option) are visible and working only on CentOS 7 whereas not on CentOS 8 or 9.
The OS is on a VMWare Workstation Pro. I have already tried to search multiple sources but unable to find a solution. I will highly appreciate if anyone could help me in this regards.
