Needs Pro, or the 14-day trial Checked against v1.11.0 Updated
- Live Cluster Monitor tab per connection, with host, MongoDB version, storage engine, uptime, and replica-set identity
- Metrics for connections and capacity, operation and document rates, memory and cache, network traffic, locks and queued work, cursors, and scan efficiency
- Replica-set member health, latency, and lag
- Health strip rating cache use, connection use, replica lag, lock queue, and active operations as healthy, warning, or critical
- Short trend charts with time-aware hover values on metrics that have history
- Operations view with Live, History, and Profiler modes
- Live mode: duration and namespace filters, sortable data, scan and lock warnings, command details, and confirmed termination
- History retains up to 200 operations of one second or longer for the tab session
- Profiler sets a database to off, slow-only, or all, and reports the threshold in effect
- Profiler mode shows the 200 most recent profiled operations, with collection summaries and JSON/CSV export
- Refresh interval of 1, 2, 5, 10, 30, or 60 seconds, with pause and resume
- Permission errors explain the MongoDB privileges the metric requires
- Monitoring stops after an error and resumes only when you retry
