Email Integration Regex Filter based on Subject

[Scott Wright]

I've created an email integration where an alert will be created and prioritized based on the subject.  

Here is the Subject from the Debug Logs: "Incident Assigned: ID: [IR244691] Priority: 3"

The email regex filter: /Priority:\s[3-4]/g

I've used regex testers and it correctly matches the subject ( I want to match Subjects with Priority: 3 and Priority: 4 ).

The Logs indicate that the email is received, but no matches were made.  Is there a trick to using regex in Opsgenie?  Can someone tell me the correct regex to use for this?

Hi @Scott Wright!

I think I helped you resolve this in a support ticket yesterday but also wanted to include the answer here in case someone else runs into a similar problem:

I think the "trick" we are looking for is that we are technically trying to match regex across the entire field you are parsing. So instead of Priority:\s[3-4], something like .*(Priority:\s[34]).* would do the trick.

When checking it in a regex tester, we want the entire field to be colored: https://regex101.com/r/OMaPwT/1

Another note is that the start/end slashes and global flags for regex aren't needed here. This page has some more information on setting up these filters and how to format the regex: https://docs.opsgenie.com/docs/regular-expressions

Yes, your solution worked for me.  Thanks!

I'm trying to pull out the node, location, and issue from a long email and this isn't working for me.  I tried it off your regex101.com link and it worked there.

Integration Extra Properties:

Node: {{ message.extract( /.*Node:\s(.*).*/ ) }}

Location: {{ message.extract( /.*Location:\s(.*\n).*/ ) }}

Issue: {{ message.extract( /.*Issue:\s(.*\n).*/ ) }}

Example email body:

Service: DNS

Node: NYCSERVER1

Location: NYC New York

Issue: Server not Responding

Room: 443

Rack: 12B

Expecting

Node = 'NYCSERVER1'

Location = 'NYC New York'

Issue = 'Server not Responding'

Hi @Scott Wright  - could you provide a screenshot of the email integration filter you have created? It sounds like you're trying to set a filter on an email integration to only create alerts if the subject contains "Priority: 3" or "Priority: 4", right?

If so, the following examples should work...

1. Just add a filter set to "match one or more conditions" that will create an alert if the subject contains either "Priority: 3" or "Priority: 4"

2. Setup the regex filter like this...

Either of those options should work if you're trying to have the integration create alerts only when it receives an email with "Priority: 3" or "Priority: 4" in the subject of the email.

Hope that helps!

Thanks,

Samir
