collectd Description

collectd is a small daemon which collects system information every 10 seconds and writes the results in an RRD-file. 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)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. 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 What's New in This Release: · New patch releases of collectd have been created. The changes include a rare but nasty race condition in the UnixSock plugin, which could lead to data being lost or being written to a wrong file descriptor. Anybody using the UnixSock plugin is advised to upgrade. · Build system: Issues when building the IP-Tables plugin have been fixed. · Exec plugin: Clear the signal block mask before calling exec(2). · Perl plugin: Declare the environ variable. This solves build issues on some platforms. · Processes plugin: Remove unnecessary call of realloc(3). Thanks to Andrés J. Díaz for the patch. · UnixSock plugin: Fix a (well hidden) race condition related to file descriptor handling.
