    It is *almost* possible to setup an Enterprise MongoDB Cluster that is on par with a Community cluster solution. There is unfortunately a lack of parity between the Official MongoDB Metrics Exporter vs Percona third party metrics exporter that is used with community cluster. This makes it challenging to build and deploy a fully supported enterprise cluster that integrates with an existing monitoring stack.

    Unfortunately, Ops-Manager also can not alert on these missing metrics independently or even visualize time-series intelligence on these metrics. Requiring a custom solution to constantly check items, like dbStats for instance, to identify DB growth that may required action.

    The following metrics are missing from official solution:

    * Total DB size (sum of size of all individual DBs)
    * individual DB size history
    * total indexes
    * indexes per DB
    * oplog size
    * oplog length and replication lag
    * total cache evictions
