Previous customization broke NODE UP/NODE DOWN
As the summary states, I've inherited pair of LTM 3600s. I am not an F5 LTM novice and I've verified all the logging levels (MCP..etc) and even looked at their config files. What do have is a BOATLOAD of custom monitors (all unused) in the /config/ directory. They've changed the default /config/monitors file and put in a couple external monitors. As a result I can't get node logging working, healthchecking actually works, it just doesn't tell me when it does. I have 2 of these in a clustered pair and the standby has the EXACT SAME ISSUE. So the problem is being sync'd by the cluster manager.
My question:
I've lost NODE UP/ NODE DOWN logging completely...Does anyone know whether or not changing /config/monitors or any other /config file could literally break a key logging function like NODE UP/DOWN?
Work done already, to no avail:
Setting every logging level in the system to debug
Verified tmm, mcp at the config file level...all defaults.
What does work:
Any iRule logging
Remote syslog logging (without node up/down either)
"No members available" messages still works, so I know when a pool is completely down.
Some highlights from the previous admins:
/config/monitors has been completely replaced with a list of external monitors (not used)
Any ideas would be much appreciated. Resetting to factory isn't an option.
