Graphite vs OpenTSDB: What are the differences?
What is 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.
What is OpenTSDB? A scalable time series database. It is a distributed, scalable time series database to store, index & serve metrics collected from computer systems at a large scale. It can store and serve massive amounts of time series data without losing granularity.
Graphite belongs to "Monitoring Tools" category of the tech stack, while OpenTSDB can be primarily classified under "Databases".
Graphite and OpenTSDB are both open source tools. It seems that Graphite with 4.63K GitHub stars and 1.21K forks on GitHub has more adoption than OpenTSDB with 3.81K GitHub stars and 1.11K GitHub forks.
Uber Technologies, Twitch, and hike are some of the popular companies that use Graphite, whereas OpenTSDB is used by Cloudinsight, SAYMON, and Server Density. Graphite has a broader approval, being mentioned in 117 company stacks & 148 developers stacks; compared to OpenTSDB, which is listed in 4 company stacks and 6 developer stacks.
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.
Pros of Graphite
- Render any graph16
- Great functions to apply on timeseries9
- Well supported integrations8
- Includes event tracking6
- Rolling aggregation makes storage managable3
