Monitoring memory usage

[Kenneth Holter]

Hello list.


Is there any best practice for which aspects of linux memory a monitoring
scout should fire a critical warning for?

Naturally, if swapping is increasing this may slow the system down,
and might be a sign that's something is wrong. But which other aspects may
be a significant threat to availability/performance on linux systems? I'm
not a linux memory management expert (yet), so please keep that in mind.


Greets,
