Ganglia vs Graphite: What are the differences?
Ganglia: Scalable distributed monitoring system. Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters; Graphite: A highly scalable real-time graphing system. Graphite does two things: 1) Store numeric time-series data and 2) Render graphs of this data on demand.
Ganglia and Graphite can be primarily classified as "Monitoring" tools.
Graphite is an open source tool with 4.59K GitHub stars and 1.2K GitHub forks. Here's a link to Graphite's open source repository on GitHub.
Looking for a tool which can be used for mainly dashboard purposes, but here are the main requirements:
- Must be able to get custom data from AS400,
- Able to display automation test results,
- System monitoring / Nginx API,
- Able to get data from 3rd parties DB.
Grafana is almost solving all the problems, except AS400 and no database to get automation test results.
You can look out for Prometheus Instrumentation (https://prometheus.io/docs/practices/instrumentation/) Client Library available in various languages https://prometheus.io/docs/instrumenting/clientlibs/ to create the custom metric you need for AS4000 and then Grafana can query the newly instrumented metric to show on the dashboard.
