Hi,
I’m still quite new to Graylog which I’m taking over from a colleague.
I’m currently looking for a major feature that I would need. But no search brought up something like that.
Can I correlate two or more log message with each other? I.e. can I check if a log message happened after an other one? Or in other words: Could I have a sort of state for a source that can be change by a certain message but otherwise stays unchanged?
To have a minimal example, let’s say I have the following messages from the same source:
Thing A turned red.
Thing B made a noise.
Thing A turned green.
Thing B made a noise.
Thing A turned blue.
Thing B made a noise.
Can I now filter for “Thing B made a noise while thing A was green”?
Thanks,
Dominik
