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.
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.
