As a Unix guy, the IBM Lotus Domino server log has always annoyed me. Since Domino is cross-platform, and Windows doesn’t have a syslog, Domino keeps its logs in a Domino database. While that makes some sense, it leads to colossal overheads; the log.nsf database is often 95% unused space. By switching my 90 days of logs to compressed syslog files, I was able to reclaim gigabytes of space.
In addition, because syslog files are just text, you can grep them, and use all kinds of open source tools to analyze them. You can use rsyslog to concentrate logs from multiple servers into a single set of logs. You can set up tasks to page you about problems. And so on.
So, I started with Daniel Nashed’s excellent rc_domino scripts, and crudely hacked them to make them pump the Domino console logs into a custom Ruby program which parses them and sends to them to syslog. You can get the code from GitHub via those links; I’ve been running it for several months now without any crashes or noticeable bugs.
Note that you still end up with events in log.nsf with this solution, but you can set it to a much shorter retention time. Hopefully at some point rc_domino will get cleaner support for console log processing. Ideally Domino would get official syslog support, but I won’t be holding my breath for that.
