Cache usage
Location: Site administration > Plugins > Caching > Cache usage.
This administration page shows the current usage of the MUC cache. It can be useful for developers (e.g. to see how much space is taken up by a particular cache) and those operating large Moodle systems (e.g. to see if some cache is building up and using too much storage, so it might need purging).
For systems with multiple servers or containers, some caches can stored locally on each server and others are shared across the whole system.
For caches which are stored locally, this page reports information only about the current server that you loaded the page on. So you might get different information if you load it from a different server.
Cache stores
A table lists all cache stores currently in use, and the estimated and actual size of each store.
Details
This table lists the individual MUC caches, which store they are in, the number of items, and some statistics about the item size:
- Mean and standard deviation of size per item.
- Estimated total size, with confidence interval.
To avoid the page taking too long to load, these statistics are based on a sample of 50 items per cache. You can use controls at the bottom to change the number of items sampled.
