Hi

You can try this

| rex "sessionCreated, Session Count: (?<sessionCreated>\d+)" 
| rex "sessionDestroyed, Session Count: (?<sessionDestroyed>\d+)"
| table _time sessionCreated sessionDestroyed

How about single rex?

Also that is working, but as you want those to separate variables it's clearer to use two (IMHO)

| eval _time = strptime(dt, "%F%T,%3Q")
```Above generates sample data```
| rex "(sessionCreated, Session Count: (?<sessionCreated>\d+))|(sessionDestroyed, Session Count: (?<sessionDestroyed>\d+))"
| table _time sessionCreated sessionDestroyed

Thanks, is it possible to extract these fields more efficiently?

What is your definition of "efficiently"?

@isoutamo has given you an answer without you having to work it out yourself; it is a single rex, as you asked for; what can be more efficient than that? 😀😀😀

I try this spl on large dataset and take long time to extract it, so I'm looking for more efficient way to do this.

Can you extract the event type and count at indexing time?
