A number of the reported Prometheus metrics are duplicated. This can be a problem for Prometheus instances configured to monitor a large number of Synapse instances.

Examples:

  • we have two copies of each counter, one with and one without a _total suffix
  • synapse_util_caches_cache:hits is duplicated as synapse_util_caches_cache_hits.
