Index of /log/2006/Aug

In the past few weeks I've been steadily improving my graphing framework, and I've added a lot of new plugins:

• Process statistics (number of dead/running/etc. processes)
• Memory usage (free/used)
• Logfiles (every line, or multiple regexes for different lines)
• Database contents (using COUNT() queries for example)

If you like graphs, check it out, and give me some feedback ;)

I've bought a 4-way temperature sensor for my new apartment, and decided that I needed to update my existing thrown-together rrdtool scripts. So I did. :)

You can get the result from http://foodfight.org/download/graph-spul, using either a plain HTTP or using bzr. It loads plugins dynamically based on the config file, and it includes 3 plugins by default (one for the temperature sensor, one for ethernet statistics, and one for reading temperatures from a hddtemp daemon).

Example output (yes I know I haven't wired up the other 3 sensors yet ;)):

I put one of my temperature sensors outside, through the hole the previous owner used to get the cable from his satellite dish inside.

After my last blog post I've been writing some more stuff for/using my new graphing framework:

• SNMP plugin, to query SNMP-capable devices.
• A new 'create' script, which will create .rrd files based on the config file.
• Some tweaks to the plugin model, so RRDtool is only called from one place.

So go ahead and download a copy from http://foodfight.org/download/graph-spul (that's a bzr repository).

Also, thanks to keyweed for writing the disk usage plugin.
