[Cialug] Memory leak!

[Don Ellis]

I think one thing we'd like (Lee & I) is some simple recipes for people
with less than massive experience at process monitoring. We hear the terms
mentioned, with "use this tool or that tool" but no guidelines for some
common conditions to look for. Are there specific symptoms for specific
kinds of pathology that would give hints that something is not as it should
be?

One caveat I see in text on this subject is: look for unexpected results,
as some process will be expected to show these conditions, and can be
ignored. Other process should not do that, and these conditions would
indicate these processes are outside normal expected range. I guess part of
this is measuring past history of every process and watching for certain
changes (which ones and how much?). There are probably monitoring tools for
this - I hope they are relatively easy to set up, with standard package
management files. Hassling with varied system configurations & tools can
really increase time investment when done across multiple platforms.
