As a ES cluster maintainer I want separate indices for Wikimedia Commons and Wikidata so that the wikipedia indices aren't afffected by commons/wikidata growth; to plan for that I need to track how resource usage for the Commons and Elasticsearch indexes are growing
Wikibase related indices are larger and growing faster than our other indices. This presents an issue for resources allocation. Isolating those indices on a specific cluster should allow better visibility, resources management / planning.
Once we have a handle on the current resource usage (T265914) and how to measure it, we need to track its growth over time so we can make plans, especially for hardware needs.
- We have a dashboard† that can track ≥ 6 months of resource usage for Commons and Wikidata Elasticsearch indexes.
† It doesn't need to be a spiffy special-purpose "dashboard", just a reliable method for viewing the relevant historical data
