Erlenmeyer is a Go Proxy used to parse multiple Open Source TimeSeries DataBase query (OpenTSDB, PromQL, Prometheus-remote_read, InfluxQL and Graphite) . Then they are translated into WarpScript to produce native Warp 10 queries.
You can test and run locally erlenemeyer following those building steps.
| Name | State | Documentation |
|---|---|---|
| Warp10 | Native | doc |
| PromQL | Near full | doc |
| Prometheus - Remote-read | Near full | doc |
| OpenTSDB | Near full | doc |
| Graphite | Partial | doc |
| InfluxQL | New | doc |
At OVHcloud, a lot of Metrics users were used to a previous TSDB experience with which they felt confortable and efficient. The goal of Erlenmeyer was to leverage their existing habits, while converging on the Metrics Time Series platform. Hence we decided to welcome customers adding more and more protocols from several Open Source Time Series DB. Under the hood, the Warp10 platform offers the powerful WarpScript query language which was a great help on this process, by just implementing all the query layers as a transpilation step. The best part of it, is now you can have: the same backend, the same data and some Grafana Dashboard written in PromQL when others are using OpenTSDB!
Erlenmeyer is used in production.
