When a critical service on a system goes down, fixing it is top priority. Unfortunately, this makes doing a post-mortem analysis more difficult-- after you've fixed the problem, doing "ps", "mailq", or whatever isn't that helpful. Question: has anyone written a script that quickly snapshots (saves to a file) the "important" values of a system? You could then quickly run "snapshot.pl" before fixing the system, and examine the output of snapshot.pl later at your leisure. If I wrote something like this, it would dump the output of "ps -aux -www", "mailq -v" (maybe), and a few other commands to /tmp/snapshot.`date` or something. Has this wheel already been invented? -- We're just a Bunch Of Regular Guys, a collective group that's trying to understand and assimilate technology. We feel that resistance to new ideas and technology is unwise and ultimately futile.
