Grafana vs Prometheus: What are the differences?
What is Grafana? Open source Graphite & InfluxDB Dashboard and Graph Editor. Grafana is a general purpose dashboard and graph composer. It's focused on providing rich ways to visualize time series metrics, mainly though graphs but supports other ways to visualize data through a pluggable panel architecture. It currently has rich support for for Graphite, InfluxDB and OpenTSDB. But supports other data sources via plugins.
What is 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.
Grafana and Prometheus can be primarily classified as "Monitoring" tools.
Some of the features offered by Grafana are:
- Create, edit, save & search dashboards
- Change column spans and row heights
- Drag and drop panels to rearrange
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
"Beautiful" is the top reason why over 65 developers like Grafana, while over 32 developers mention "Powerful easy to use monitoring" as the leading cause for choosing Prometheus.
Grafana and Prometheus are both open source tools. Grafana with 29.7K GitHub stars and 5.63K forks on GitHub appears to be more popular than Prometheus with 25K GitHub stars and 3.55K GitHub forks.
Uber Technologies, 9GAG, and Harvest are some of the popular companies that use Grafana, whereas Prometheus is used by Uber Technologies, Soundcloud, and DigitalOcean. Grafana has a broader approval, being mentioned in 577 company stacks & 325 developers stacks; compared to Prometheus, which is listed in 243 company stacks and 85 developer stacks.
