A good list of CLI commands to do a health check on a BIG-IP LTM

I'm trying to come up with a good list of CLI commands to do a health check on a BIG-IP LTM. The idea is to run all the commands on a BIG-IP to see if it's OK before/after a manual failover.

  1. <> Check system CPU usage
  2. tmsh show sys cpu
  3.  
  4. <> Check traffic-group active/standby mapping
  5. tmsh show cm traffic-group
  6.  
  7. <> Check connection mirror process
  8. tmsh show sys ha-mirror
  9.  
  10. <> Check sync status
  11. tmsh show cm sync-status
  12.  
  13. <> Check how many current connections are up in every VS in all partitions
  14. tmsh show ltm virtual /*/* | grep "Ltm::Virtual\|Availability\|Current Connections"
  1. tmsh show sys connection // check current open connections
  2. tmsh show ltm persistence persist-records // Check persist records
  3. tmsh show sys traffic // check statistics of traffic
  4. tmsh show sys tmm-traffic // check statistics of traffic at TMM
  5. tmsh show sys pva-traffic // check statistics of traffic at PVA
  6. tmsh show sys ip-stat // check statistics of IP traffic
  7. tmsh show sys icmp-stat // check statistics of ICMP traffic
  8. tmsh show sys performance  // check statistics of performance
  9. tmsh show sys mcp-state // show status of MCP
  10. tmsh show sys proc-info // check info of processes
  11. tmsh show sys log  // check logs (ltm, apm, gtm, audit,...)
  12. tmsh show net arp // show ARP table
  13. tmsh show net route // show Routing table
  14. tmsh show sys ip-address // show IP configured in BigIP

The iQuery protocol uses TCP port 4353 to connect to synchronization group member

  1. tmsh show sys memory // Check memory usage
  2. tmsh show sys cluster // Check status of slots from a guest
  3. tmsh show cm failover-status // Check failover status
  4. tmsh show sys disk // Check disk
  5. tmsh show sys raid // Check raid
  6. tmsh show sys hardware // Here you have info about status of power supply
