[Feature Request] Counter for Events
In an internal LogViewer of my Company we have a feature so called counter to count events inside the log files.
This will be done by setting a Regex for UP-counting and one for DOWN-counting.
In our case it will show the current value of the counter in front of every log entry.
This makes it really easy to detect memory leaks for example (more allocs then frees).
Maybe such an counter will be a useful tool for others.
I see this being useful in some cases. I am not sure what the UI for this feature in klogg should be. Klogg shows a count of matches, so doing two searches and subtracting the matches counts achieves the same result, but indeed in a more cumbersome manner.
The idea in our tool is that I can see the count at any point in time.
For example, if our application is dynamically allocating and freeing buffers for received data, I can see the current number of allocated memory pools at any point in time (regex on recvBufferAlloc/recvBufferFree).
This can also be quite useful to detect performance issues if the count increases over time.
This is not possible if only a "total difference" between two searches is shown.
Maybe such an function can be integrated via an "plugin"-interface or something?
Yes, this seems to be a good use case for plugins. There was a fork of klogg that implemented python plugins support. Not sure where it is now.
Fork is here https://github.com/dkinsbur/klogg. However, it is quite outdated
