Projects / collectd


collectd is a small and modular daemon which collects system information periodically and provides means to store the values. Included in the distribution are numerous plug-ins for collecting CPU, disk, and memory usage, network interface and DNS traffic, network latency, database statistics, and much more. Custom statistics can easily be added in a number of ways, including execution of arbitrary programs and plug-ins written in Perl. Advanced features include a powerful network code to collect statistics for entire setups and SNMP integration to query network equipment.

            I've been longing for thingie like that for quite a time (but never overcame the laziness).

            Now trying to bring ALT Linux package into the best shape currently possible, also running it at one of the systems already; hope to get back with at least something useful.
