collectd is a small daemon which collects system information every 10 seconds and writes the results in an RRD-file. The statistics gathered so far are: (Only Load and CPU usage work under Solaris right now. Ping might work, lm-sensors propably not)

Here are some key features of "collectd":
Memory usage
CPU usage
System load
Network traffic
Network latency (ping)
System temperatures (if lm-sensors is configured)
Disk usage

In contrast to most similar software, collectd is not a script but written in plain C for performance and portability. collectd stays in the memory so there is no need to start up a heavy interpreter every time new values should be logged. This allows collectd to have a 10 second resolution while being nice to the system.

collectd reads most information from the /proc-filesystem. Support for the sysfs approach is not yet planned/done, but theres no reason not to do that other than me not having time to code it right now.. Solaris statistics are collected using the kstat mechanismn that appears to be very solaris-specific. Also, it's not done yet, version 1.6.0 collects system load and cpu usage, nothing more.

collectd has successfully been tested on x86 under Debian GNU/Linux 3.1 (sarge), RedHat Linux 7.x, and Fedora Core 1. Also, Debian/Sparc and Solaris 9 did work. Other Platforms/Distributions are expected to work too. If you manage to compile and run collectd on other systems and/or under different distributions please drop me a line.

What's New in This Release:
A bug in the ntpd-plugin has been fixed: due to an incorrect calculation of a buffer's size, uninitialized or freed memory regions could have been read.
