Time series

The Open Source Metrics family welcomes Catalyst and Erlenmeyer

At OVHcloud Metrics, we love open source! Our goal is to provide all of our users with a full experience. We rely on the Warp10 time series database which enables us to build open source tools for our users benefit. Let’s take a look at some in this blogpost. Storage tool Our Infrastructure is based …

Jerem: An Agile Bot

At OVHCloud, we are open sourcing our “Agility Telemetry” project. Jerem, as our data collector, is the main component of this project. Jerem scrapes our JIRA at regular intervals, and extracts specific metrics for each project. It then forwards them to our long-time storage application, the OVHCloud Metrics Data Platform.   Agility concepts from a developer’s …

TSL - Time Series Language

TSL: a developer-friendly Time Series query language for all our metrics

At the Metrics team we have been working on time series for several years. From our experience the data analytics capabilities of a Time Series Database (TSDB) platform is a key factor to create value from your metrics. And these analytics capabilities are mostly defined by the query languages they support. 

TSL stands for Time Series Language. In a few words, TSL is an abstracted way, under the form of an HTTP proxy, to generate queries for different TSDB backends. Currently it supports Warp 10’s WarpScript and  Prometheus’ PromQL query languages but we aim to extend the support to other major TSDB.

To better understand why we created TSL, we are reviewing some of the TSDB query languages supported on OVH Metrics Data Platform. When implementing them, we learnt the good, the bad and the ugly of each one. At the end, we decided to build TSL to simplify the querying on our platform, before open-sourcing it to use it on any TSDB solution. 

Why did we decide to invest some of our Time in such a proxy? Let me tell you the story of the OVH metrics protocol!
