collectd vs Prometheus: What are the differences?
collectd: System and applications metrics collector. collectd gathers statistics about the system it is running on and stores this information. Those statistics can then be used to find current performance bottlenecks (i.e. performance analysis) and predict future system load (i.e. capacity planning). Or if you just want pretty graphs of your private server and are fed up with some homegrown solution you're at the right place, too; Prometheus: An open-source service monitoring system and time series database, developed by SoundCloud. Prometheus is a systems and service monitoring system. It collects metrics from configured targets at given intervals, evaluates rule expressions, displays the results, and can trigger alerts if some condition is observed to be true.
collectd and Prometheus can be categorized as "Monitoring" tools.
Some of the features offered by collectd are:
On the other hand, Prometheus provides the following key features:
- a multi-dimensional data model (timeseries defined by metric name and set of key/value dimensions)
- a flexible query language to leverage this dimensionality
- no dependency on distributed storage
collectd and Prometheus are both open source tools. It seems that Prometheus with 24.6K GitHub stars and 3.49K forks on GitHub has more adoption than collectd with 2.24K GitHub stars and 1.08K GitHub forks.
