NimbostratusGTM iRules not logging
I'm seeing some odd behavior on two GTM devices. I have the following iRule that I'm using to troubleshoot:
when DNS_REQUEST {
log local0. "(Request) Client: [IP::client_addr] - Request: [DNS::rrname] - Type: [DNS::rrtype]"
}
when LB_SELECTED {
log local0. "(Balanced) Server: [LB::server]"
}
when LB_FAILED {
log local0. "(Failure) Failed to balance"
}

Hi,
how do you know the iRule is not beeing processed? Did you check /var/log/ltm for the log messages (iRule log messages go there)?

ltp_55848Hi Kurt, the rules aren't producing output in any logfile under /var/log, hence what lead me to believe that the rules were not working.
I've updated the rule to also log on a RULE_INIT event, which does generate a log event, however the other event types are not being matched.- Kurt_Knochner_5O.K. I'm using similar iRules on GTM and they do log into /var/log/ltm.
can you please:
1.) tell me the TMOS version of your GTM ("b version")
2.) post the wide ip configuration, containing the iRule (/config/gtm/wideip.conf)
Regards
Kurt Knochner - ltp_55848Hi Kurt,
the problem turned out to be due to the listeners on which the iRules were applied not being in the same route domain as the incoming request, hence they were never being triggered.
