CirrusFire irule when condition met
Hello, is there a way to fire an irule when a condiftion met (such as VS connction limit is reached 90%).
I thought about "/etc/alertd/alert.conf" file, but i don't know to fire the irule inside ...
Sample implementation:
/config/alert_user.confTestMevs/var/log/ltmalert st_exec_command "I sense something" {
exec command="tmsh modify ltm virtual vs rules { TestMe }"
}
Send a test log message:
logger -p local0.info "I sense something; a presence I have not felt since..."
Check if the iRule is attached:
tmsh list ltm virtual vs rules
ltm virtual vs {
rules {
TestMe
}
}
Access the virtual. See if it fired. In this example, the
TestMeJul 26 12:18:36 ltm1310 info tmm[12214]: Rule /Common/TestMe : Obi-Wan is here. The Force is with him.
You need to find the exact log message that trigers the iRule. If the virtual already had other iRules, the logic may become more complex. In that case, you may want to write a tmsh script.
