As explained thoroughly in an earlier post, the P19 migration meant we needed to add a new element to our infrastructure… namely the ProxySQL. Life was not easy for it at first, but it soon learned how to handle the diverse range of configurations your websites have, particularly when it comes to making sure the path connecting […]

In our previous post, we outlined the reasons that led us to create an Agile monitoring tool. To capitalise on this collective success, we needed to: Establish an efficient, simple and universally-accepted methodology to support the development teams. Set out the different visions necessary for the good handling of a project. Define the micro vision,

As developers, we often need to execute tasks in the background. Fortunately, some tools already exist for this. In the Python ecosystem, for instance, the most well-known library is Celery. If you have already used it, you know how great it is! But you will also have probably discovered how complicated it can be to

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

“You don’t have a chance.” “You’re already dead.” “You’ll get eaten alive.” For the last 21 years, I’ve heard people say these things several times a week. They’re often said by people who don’t really understand what OVHcloud does. Never by people in the field. I don’t blame them. They’re clearly thinking “It can’t be

In October 2018, just before the OVHcloud Summit, I joined the Product Unit Platform as Program Manager. A new challenge came with this new role… to support the team working on a new product: OVHcloud Managed Kubernetes.

Last year, we released TSL as an open source tool to query a Warp 10 platform, and by extension, the OVHcloud Metrics Data Platform. But how has it evolved since then? Is TSL ready to query other time series databases? What about TSL states on the Warp10 eco-system? TSL to query many time series databases
