PostgreSQL

Monitoring metrics for PostgreSQL is crucial to optimize performance, detect issues early, ensure resource efficiency, enhance security, plan for scalability, validate backups, and analyze long-term.

Metrics	Description
Postgres Status	Indicate PostgreSQL Status
Shared Buffers Size	Caches data to reduce disk I/O in PostgreSQL
Available Storage in GB	Provide details for total available storage
Available Connections	Calculate the available connections
Maximum Active Transaction Time by DB	Retrieve max transaction duration for active PostgreSQL sessions
Cache Hit Rate	Showing the cache hit rate percentage
Transactions	Total committed transactions in PostgreSQL over time
Database size in GB	Size of all databases in GB
Conflicts/Deadlocks	Track PostgreSQL deadlocks and conflicts.
Rows	Get PostgreSQL tuple statistics: fetch, return, insert, update, delete.

Postgres Status:

Postgres Status

Provide information about database status.

Uptime Status

Monitor PostgreSQL uptime metrics for performance insights. Enhance database reliability and performance.

Shared Buffers Size In MB

Optimize PostgreSQL performance by analyzing shared buffer size in megabytes. Ensure efficient memory allocation for improved database responsiveness and reduced query execution times.

Available Storage in GB

This expression calculates the aggregated available disk space in gigabytes within a PostgreSQL environment, contributing to comprehensive storage monitoring and capacity planning for optimized system performance.

Available Connections

This expression computes the effective available PostgreSQL connections by subtracting active connections and reserved superuser connections from the maximum allowed connections. Useful for monitoring and optimizing database connection utilization in a specified context.

Maximum Active Transaction Time by DB

This expression captures the peak transaction duration for active processes, providing insights into transaction performance within a specific context.

Cache Hit Rate

This expression calculates the hit ratio percentage for database block access, indicating the proportion of successfully retrieved blocks compared to total reads and hits over time.

Transactions

This expression measures the rate of committed transactions over time in a specified context, providing insights into the frequency of successful transaction commits.

Database size in GB

Measure size of critical PostgreSQL databases (excluding system databases) in gigabytes. Useful for managing storage resources and optimizing database performance in a specified environment.

Conflicts/Deadlocks

Calculate the sum of deadlocks and conflicts rates in a PostgreSQL database. Monitor and analyze these metrics to identify and address performance issues for enhanced database reliability

Rows

This set of expressions calculates the summed rates of returned, inserted, updated, and deleted tuples per second, providing insights into the transactional activity of a specified context in PostgreSQL.
