The collectd
command is used to start the collectd daemon on a Unix-like system. Collectd is an open-source system statistics collection daemon that gathers information about the performance and behavior of the system and stores it for later analysis.
When the collectd
command is executed, it initializes the collectd daemon, which will begin collecting system statistics based on the configuration defined in its configuration file. The daemon collects a wide range of metrics including CPU usage, memory usage, disk usage, network activity, and many others, depending on what plugins are enabled.
The collected data is typically stored in a time-series database such as RRDtool or InfluxDB, which can be later visualized using tools like Grafana or analyzed with custom scripts. The continuous data collection and storage provided by collectd allow system administrators and operators to monitor system performance, identify bottlenecks, and make informed decisions for optimizing system resources.
