I have been developing scripts that can:
- Clean up existing server hosts statements, unless they are the correct. If they are correct, bypass the next steps
- Validate the server hosts - if missing or incorrect will add
The problem I am running to is with the trigger filtering on the CLEANUP_SNMP_SERVER_HOST_TRIGGER trigger. Our 2 valid hosts are 192.168.1.1 and 192.168.2.2. I need a filter that will say: If the ip address is NOT equal to 192.168.2.2 or 192.168.1.1 and SNMP_WORD_0 is or contains network. (I used a Ruby Regex generator FYI.)
I tried to write multiple expression but either I'm not writing it correctly or I don't think NetMRI is interpreting them correctly.
Trigger-Filter:
$SNMP_HOST_0 like /\b(?:25[0-5]|2[0-4][0-9]|1[0-9]{2}|[1-9][0-9]?)\.[0-9]{1,3}\.[0-9]{1,3}\.(?:0|25[0-5]|2[0-4][0-9]|1[0-9]{2}|[1-9][0-9]?)\b/ and $SNMP_WORD_0 like /network.*/
Any assistance on how to write a filter or a reg expression that would meet these conditions.
Thanks!
