How to deciper log text

Olaoluwa Adewoye · Nov 18, 2023

Hello, I am going through the log files of my instance and I wanted to know what each part of it meant. I've tried going through the documentation but I wanted clarification.

I understand there is a log viewer, but I want to understand this directly through the text file. For example, if I were to read this-

"11/06/23-21:00:46:680 (444) 0 [Utility.Event] Performing Journal Recovery"

What would each part of this line be called?

Thank you for your assistance.

Date, time, process / job id, log level, event type, log message.

Log level 0 is normal, 2 is warning, 3 is critical

Log level is not always a good indicator of how big a deal what is being logged is.
For example:
2 [Generic.Event] Unable to allocate shared memory minimum - this error prevents startup so critical
1 [Generic.Event] MirrorServer: Lost ReadDmn (ACK) connection to async - loss of connection connection to a mirror doesn't rate as even a warning?

By the way using Structured Logging might also be useful in this context.
