The Wikimedia Server Admin Logs

The Wikimedia Server Admin Log or SAL for short is a timestamped log of actions performed on the Wikimedia cluster by users such as roots and deployers. The log is stored on the WikiTech Wikimedia project and can be found at the following URL: https://wikitech.wikimedia.org/wiki/Server_Admin_Log

An example entry in the log could be:

As well as the main cluster SAL there are also logs for release engineering (jenkins, zuul, and other CI things) and individual logs for each project that uses Wikimedia Cloud VPS.

A tool has been created for easy SAL navigation which can be found at https://tools.wmflabs.org/sal

Each SAL can be selected at the top of the tool, with ‘Other’ providing you with a list of all Cloud VPS SALs.

The search and date filters can then be used to find entries throughout history.
