Prometheus

Prometheus is an open-source monitoring and alerting toolkit. It collects metrics as time-series data using an HTTP pull model and supports flexible queries and real-time alerting. Prometheus is written in Go and licensed under the Apache 2.0 License.

Rocket.Chat provides monitoring dashboards based on Prometheus and Grafana to help visualize system metrics and performance data.

These dashboards can display metrics such as:

General totals: Users online/away, DDP users, and activity differences over time.
Metrics: Request counts and total size per instance.
Node.js: Active handles, requests, event loop lag, heap usage, and garbage collection metrics.
DDP Rate Limiter: Rate limits by method, type, user ID, and connection ID.
Rocket.Chat Data: Messages sent, user presence, sessions, oplog activity, push queue, total users, rooms, and notification metrics.
Meteor: Method execution time, total method calls, and calls per minute.
Subscriptions: Subscription processing time and calls per minute.
Callbacks & Hooks: Callback and hook execution metrics and frequency.
REST API: API execution time and call rate.
