Logfile Extension and Regular Expressions

[Hoosain.Madhi]

how do I use a regular expression to match a pattern in a logfile - I am using LogFile extension

for example from the following line specific to a "Response" msg

{"remoteHost":"epdg","epoch":1648084954231,"command":"Response","Result-Code",{"value":1001}},"statusCode":"2001","status":"FOO ","timestamp":"2022-03-24 03:22:34.231"}

can I use a regular expression to find statusCode NOT 2001 indicating a failure - If so what regex should I use?

cant seem to find documentation

After looking at all possible statusCodes the regex I came up with is :

.*"command":"Response".*"statusCode":"[1|3|4|5].*".*

I am not sure on what to put in the config.yml – any ideas?

- displayName: "Diameter-EAP-Response-Failures"

    pattern: "?????"

    matchExactString: false

    caseSensitive: false

    printMatchedString: false
