pgMonitor combines a suite of tools to facilitate the collection and visualization of important metrics that you need be aware of in your PostgreSQL database and your host environment, including:
- Connection counts: how busy is your system being accessed and if connections are hanging
- Database size: how much disk your cluster is using
- Replication lag: know if your replicas are falling behind in loading data from your primary
- Transaction wraparound: don't let your PostgreSQL database stop working
- Bloat: how much extra space are your tables and indexes using
- System metrics: CPU, Memory, I/O, uptime
pgMonitor is also highly configurable, and advanced users can design their own metrics, visualizations, and add in other features such as alerting.
Running pgMonitor will give you confidence in understanding how well your PostgreSQL cluster is performing, and will provide you the information to make calculated adjustments to your environment.
