MongoDB collstats metricset

This is the collstats metricset of the module mongodb.

It is using the top administrative command to return usage statistics for each collection. It provides the amount of time, in microseconds, used and a count of operations for the following types:

  • total
  • readLock
  • writeLock
  • queries
  • getmore
  • insert
  • update
  • remove
  • commands

It requires the following privileges, which is covered by the clusterMonitor role:

This is a default metricset. If the host module is unconfigured, this metricset is enabled by default.
