BIG-IP LTM - Usefull CLI health check commands

Hello Devs! 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 fail...
application delivery
LTM
TMSH

All mentioned commands are good. Also, you can use:

 

tmsh show sys connection // check current open connections
tmsh show ltm persistence persist-records // Check persist records
tmsh show sys traffic // check statistics of traffic
tmsh show sys tmm-traffic // check statistics of traffic at TMM
tmsh show sys pva-traffic // check statistics of traffic at PVA
tmsh show sys ip-stat // check statistics of IP traffic
tmsh show sys icmp-stat // check statistics of ICMP traffic
tmsh show sys performance  // check statistics of performance
tmsh show sys mcp-state // show status of MCP
tmsh show sys proc-info // check info of processes
tmsh show sys log  // check logs (ltm, apm, gtm, audit,...)
tmsh show net arp // show ARP table
tmsh show net route // show Routing table
tmsh show sys ip-address // show IP configured in BigIP

There are many manual to troubleshoot LTM/GTM modules that you can use to perform a heath check.
