healthiness of F5 - help with errors
Dear Gents,
I am reviewing /var/log/ltm logs and KPI statistics on two high available F5s running on release 12.1.3. I am looking for root cause of high memory or CPU usages. There are several problems bellow.
Q1 First of all other memory utilization is hitting 70 % (tmm memory just 20%). Also CPU usage is hitting over 70% in peaks. Is there any hint how or where to start high memory or CPU usage issue troubleshooting? F5 is used as loadbalancer. There is very low traffic flowing across F5s around 50 Mbps.
Q2 There is seen in ltm logs following error: mcpd[7118]: Sync of device group /Common/device-group-failover-2530624eebc7 to commit id 6666 Is it something on which keep eye?
Q3 There is error with unreachable pool member and failing monitor ( err f5-A tmm[12726]: No members available for pool /poolX/pool_A
ltm 07-31 05:43:50 notice f5-A mcpd[7118]: Pool /part_X/pool_A member /part_www/10.XX.YY.ZZ:80 monitor status down). I can fix it easily but can such unreachable pool member use high CPU or Memory usage?
Any advice helping troubleshooting errors above would be highly appreciated. Many thanks
Regards
Andy
