Decrypting the /var/log/ltm health monitor

When a site goes down the log will show the pool member that went down with error code 01070638. I need to know what each delimited part means because I get a string of text and I don't know what it'...

the error codes themselves are not published, and I'm not sure they'd be terribly helpful to you anyway. Better would be to enable monitor debugging:

tmsh modify sys db bigd.debug value enable

This will give you detailed logs in /var/log/bigdlog

Just make sure you disable the debug when you are done:

tmsh modify sys db bigd.debug value disable
