Evaluating Grafana and Kibana

Variations between Grafana and Kibana at a look:

Information sources

Grafana helps a number of knowledge sources like Prometheus, InfluxDB, OpenTSDB, and so on. It additionally helps Elasticsearch as an information supply. Centered on visualizing metrics from time-series databases, Grafana formally helps a number of knowledge sources. Listed here are just a few of the favored ones:

• AWS Cloudwatch
• Azure Monitor
• Elasticsearch
• Google Cloud Monitoring
• Graphite
• InfluxDB
• Loki
• MySQL
• Prometheus
• InfluxDB
• Jaeger
• Tempo
  Then again, Kibana solely helps Elasticsearch as an information supply.

Dashboard and Visualization

Each Kibana and Grafana supply an amazing set of visualization capabilities.

Grafana helps graph, single stat, desk, heatmap, free textual content panel sorts, and so on., which could be configured with quite a lot of knowledge sorts. Grafana is constructed for cross-platform visualizations and may combine knowledge from a number of sources to create dashboards. Every panel in a Grafana dashboard corresponds to a particular knowledge supply, however a number of panels with completely different knowledge sources could be mixed to create a wealthy dashboard.

Kibana gives all kinds of visualization sorts, permitting you to create pie charts, line charts, knowledge tables, single metric visualizations, geo maps, and so on. Other than the fundamentals, Kibana additionally gives visualizations for the next analyses:

• Location evaluation
• Time sequence evaluation
• Machine studying
