collectd 4.7.0

collectd is a small daemon which collects system performance statistics periodically and provides mechanisms to store the values in a variety of ways, for example in RRD-files.
collectd gathers information about the system it is running on and stores this information.
The information can then be used to predict future system load (i. e. capacity planning) or to find current performance bottlenecks (i. e. performance analysis) and .
Or if you just want pretty graphs of your private server and are fed up with some homegrown solution youre at the right place, too.
While collectd can do a lot for you and your administrative needs, there are limits to what it does:
- It does not generate graphs. It can write to RRD-files, but it cannot generate graphs from these files. Theres a tiny sample script included in contrib/, though. Also you can have a look at drraw for a generic solution to generate graphs from RRD-files.
- It does not do monitoring. The data is collected and stored, but not interpreted and acted upon. Theres a plugin for Nagios, so it can use the values collected by collectd, though.

Enhancements
- The abilty to sign or encrypt network traffic has been added to the network plug-in. A new plug-in embeds a Java VM that allows you to load and run plug-ins written in Java.... Other new plug-ins allow the daemon to collect the size of the connection tracking table under Linux, details about the FS-Cache feature of Linux 2.6.30, detailed network protocol data, and power consumption via T.E.D. devices. The new memcachec plug-in parses data fetched from a memcached server. Ganglia interoperability has been added. Statistics collected by the MySQL plug-in have been extended
