# PostgreSQL Performance Monitoring PostgreSQL, also known as Postgres, is a free, open-source, enterprise-class relational database management system. Organizations looking for database solutions that help build applications, provide data integrity, and build fault-tolerant environments choose PostgreSQL. Despite its outstanding capabilities, managing PostgreSQL database is a tedious process as it is still prone to performance issues such as slow queries, replication errors, primary node failures, etc. Therefore, IT Operations teams need a **PostgreSQL performance monitoring** solution in place to aid the smooth functioning of the database system. Applications Manager serves as one of the best **PostgreSQL performance monitoring tools** in the industry that helps maintain your databases efficiently. ## Explore PostgreSQL performance monitoring with ManageEngine Applications Manager ## Track key PostgreSQL performance metrics Applications Manager's **PostgreSQL performance monitor** gathers data on crucial PostgreSQL performance metrics that help database administrators identify performance bottlenecks, employ corrective actions to resolve them, and ensure smooth operation of the system. ### Here are some PostgreSQL performance metrics that you need to keep tabs on: **Connection statistics:** Keep an eye on the number of active connections in the database. Become mindful of total users in the database. ![PostgreSQL Performance Monitoring - ManageEngine Applications Manager](https://www.manageengine.com/products/applications_manager/images/ppm-query-details.webp) **Lock statistics:** A database involves execution of complex transactions that fetch, modify/alter data. PostgreSQL utilizes locks to perform serial changes to important sections of the database. Applications Manager's **PostgreSQL performance monitoring tool** tracks lock statistics and gives you insights on data locks, helping you detect performance degradation due to lock contention. ![PostgreSQL Performance Monitoring Tool - ManageEngine Applications Manager](https://www.manageengine.com/products/applications_manager/images/ppm-query-details.webp) **Buffer statistics:** Applications Manager's [Postgres monitoring](https://www.manageengine.com/products/applications_manager/postgres-monitoring.html) helps track buffer hits and blocks reads/min and capture cache-hit ratio value. Analyze cache Hit Ratio values and take necessary steps if the value becomes low as it degrades PostgreSQL performance. ![PostgreSQL Performance Monitoring Tool - ManageEngine Applications Manager](https://www.manageengine.com/products/applications_manager/images/ppm-buffer-statistics.png) **Disk usage details:** With Applications Manager's PostgreSQL performance monitor, plan capacity of PostgreSQL database better by keeping tabs on the disk and index usage. If you see a surge in index usage, you may need to analyze and get rid of unused indexes as they are said to slow down data modification and the backup processes. ![PostgreSQL Performance Monitoring Dashboard - ManageEngine Applications Manager](https://www.manageengine.com/products/applications_manager/images/ppm-disk-usage-details.webp) **Index scan details:** Index scans fetch all the required values entirely from the index without visiting the table at all. This helps accelerate the execution of a query. Applications Manager's PostgreSQL performance monitor tool tracks the index Scans, reads, and fetches that occur every minute. ![PostgreSQL Performance Monitoring Software - ManageEngine Applications Manager](https://www.manageengine.com/products/applications_manager/images/ppm-index-scan-details.webp) **Query statistics:** Monitoring PostgreSQL performance activity with Applications Manager also involves gathering information about the number of rows inserted, updated, and deleted every minute. This helps you gain insight into the type of queries your database serves. ![Postgres Performance Monitoring - ManageEngine Applications Manager](https://www.manageengine.com/products/applications_manager/images/ppm-query-statistics.webp) **Transaction details:** With Applications Manager's PostgreSQL query performance monitoring tool, keep an eye on the number of commits and rollbacks taking place in your database. Higher values of commits usually indicate increased efficiency of server. ![Postgres Performance Monitoring Solution- ManageEngine Applications Manager](https://www.manageengine.com/products/applications_manager/images/ppm-transaction-details.png) **Session details and database details:** Applications Manager's [PostgreSQL monitoring](https://www.manageengine.com/products/applications_manager/postgresql-monitoring.html) capabilities also allow you to monitor PostgreSQL sessions. It displays the top 10 queries by CPU utilization and shows a list of long-running queries. This information helps you analyze which queries are slowing the database. ![PostgreSQL Performance Monitoring System - ManageEngine Applications Manager](https://www.manageengine.com/products/applications_manager/images/ppm-query-details.webp) ## Detect and fix issues quickly. Applications Manager's PostgreSQL performance monitoring software's capabilities include notifying you on breach of thresholds. These thresholds can be set for individual attributes along with which alarms are configured. Certain corrective actions can also be associated with these alarms and will be executed when an alarm is triggered. These can come a long way in maintaining the health of PostgreSQL and improving the performance as well preventing major database disasters.
