20:12 [ptc] moritz: how's this for an idea: parsing logwatch emails
20:12 [ptc] I have this problem at work that I'm yet to attack (many other things with higher prio), and that's to go through our logwatch emails to get trends about our servers that I don't yet have
20:13 [ptc] when I set up the systems I wasn't able to set up Nagios or Cacti (something which I still want to do, and have an idea as how to do that in the open internet, but that's another story...)
20:14 [ptc] anyway, in order to get an idea of e.g. disk space trends over time I thought I could process the old logwatch emails so that at least I get an idea of what's happening on the various partitions on my machines
20:14 [ptc] since the format is reasonably well defined, one might be able to use regexes (or better, a grammar) to parse the information, store it in a csv file (or better an SQL-DB) and then plot
20:15 [ptc] this is not only a relevant problem (i.e. other people might have it and it helps the reader think that they can use Perl6 for real-world problems now), but it also could fit as a good example of parsing, regexes and grammars
20:16 [ptc] another thing that I'd like to do, that's not possible with system monitoring tools very easily, is to work out how well fail2ban is working
20:16 [ptc] it'd be good to work out how many attacks are happening on a given system over time, and if one IP manages to get more login attempts through than others
20:18 [ptc] this could also be parsed out of the old logwatch data, is a bit more unstructured (and hence a bit more challenging), however could be illustrative and useful
20:31 moritz [ptc]: do you have a few example logwatch emails that you could send me in a tarball or something?
20:32 moritz [ptc]: the idea sounds interesting, I just don't know enough about logwatch to judge its feasibility right now
20:35 [ptc] ok, will send a few through in a bit
21:19 [ptc] moritz: examples underway
21:53 moritz [ptc]: thanks
