Hi @jerinvarghese,
Try this:

| rex "\d{4}-\d{2}-\d{2}T\d\d:\d\d:\d\d+\+\d\d:\d\d\s+(?<device>[^ ]+)\s+\<\d+\>\s+\%(?<alarm>\w+-\w+)[^ ]*\s+\(\d+\)\s+(?<message>[^\(]+)((\s+\(\d+\s+)|$)"

that you can test at https://regex101.com/r/zuJBnj/1 .

Ciao.

2020-04-04T15:08:05+00:00 usdaldc <44>  %WAAS-HTTPAO-4-131001: (143581) worker pool isn't healthy
2020-04-04T15:08:05+00:00 usdaldc <43>  %WAAS-HTTPAO-3-131003: (143528) AOSHELL worker thread

New alarms that I notice and the regex that i created.

    |rex fiel=_raw "\d{4}-\d{2}-\d{2}T\d\d:\d\d:\d\d+\+\d\d:\d\d\s(?<device>[^ ]+)\s<\d\d>\s\s%(?<alarm>\w+-\w+)[^ ]\d-\d{6}:\s(?<message>[^\(]+)"

Hi @jerinvarghese,
the new log is different from the previous,
if it could be acceptable for you that the message is all the last part of the log, try tris:

| rex "\d{4}-\d{2}-\d{2}T\d\d:\d\d:\d\d+\+\d\d:\d\d\s(?<device>[^ ]+)\s<\d\d>\s\s%(?<alarm>\w+-\w+)[^ ]*\s+(\(\d+\)\s+)*(?<message>.*)"
