The record

Purpose: collectd is a daemon that periodically collects system and application performance metrics and provides mechanisms to store them in various ways.
Metric sources: It gathers metrics from operating systems, applications, logfiles, and external devices.
Uses: Collected statistics can be used to monitor systems, find performance bottlenecks, and predict future system load.
Performance and portability: The project says collectd is written in C for performance and portability, including use on systems without a scripting language or cron daemon.
Plugins: The homepage says the daemon comes with over 100 plugins.
Scale: The homepage says collectd includes optimizations and features to handle hundreds of thousands of metrics.
Storage and graphs: collectd can write to RRD files but does not generate graphs from them.
Monitoring limit: The homepage says its monitoring functionality is limited to simple threshold checking.
Download formats: The download page offers source packages as GZip or BZip2 compressed tar archives.
Platforms: The download page lists packages or ports for Debian and Ubuntu, Fedora, openSUSE and SLES, Red Hat and CentOS, FreeBSD, Solaris, OpenWrt, and T2 SDE.
Windows: The download page points to SSC Serv, a native Windows application that collects and dispatches performance data using the collectd network protocol.
Support: The project directs bug reports to its bug tracker and uses its mailing list for announcements and development discussions.
Security contact: The contact page provides [email protected] and GnuPG key 0x0C705A15 for reporting sensitive security issues.
