If anyone know how to save f5 irules logs to excel sheet
Normally all the logs related to iRules are present under /var/log ltm files which can be export under excel or text files. Normally when i required to take logs specific to one iRule, i do following.
cat ltm | grep <irule-name> >>/var/tmp/irule-logs.csv
Above command filters all the logs entries related to mentioned iRULE name and captured it under csv file with given name at given path on the F5.
