MongoDB & Replica Set — Full Overview

All-in-one MongoDB + Replica Set + Database Activity overview.

A Grafana dashboard for monitoring a MongoDB replica set via the Percona mongodb_exporter + Prometheus.

Requirements

The exporter started with these flags:

--compatible-mode
--collector.replicasetstatus
--collector.dbstats
--collector.topmetrics
--collector.indexstats
--collector.diagnosticdata

In Grafana: Dashboards → New → Import
Upload mongodb-dashboard-clean.json (or paste its contents)
When prompted, select your Prometheus data source
Open the dashboard and set the Instance variable (top left) to your target host

Section	Shows
Overview	Up/down, this node's role, connections, page faults, replica member status table
Replica Set	Member state, health, ping, replication lag
Sync Status	In-sync / lagging / out-of-sync per member, plus last-synced timestamp
Database Activity	Reads/sec and writes/sec per database, DB sizes
Operations	Command ops, document ops, query efficiency, queued ops
Resources	Memory, WiredTiger cache, connections trend, asserts
Cursors	Open cursor counts

All queries filter on instance="$instance" — make sure that variable is set or panels will show no data.
Some panels use label names specific to this exporter build (e.g. mongodb_ss_metrics_document with a doc_op_type label). If your exporter version differs, a panel may need its query adjusted.
