Postgres Monitoring

Why is Postgres monitoring tool important?

Databases such as PostgreSQL must be well maintained to ensure high performance of the mission-critical applications that connect to them. Applications Manager serves as one of the best Postgres performance monitoring tools in the industry, and offers extensive Postgres monitoring that helps database administrators guarantee uninterrupted long-term operations with negligible downtime and predictable overheads.

Ensure optimal performance of Postgres Database

When it comes to Postgres performance monitoring, there are a number of vital metrics that you need visibility over, to effectively manage your databases. Our comprehensive Postgres database monitoring tool allows you to:

  • Detect slow performance by monitoring the number of active connections. If the number of connections is high, you may need to analyze the state of these user sessions and terminate idle sessions that are unnecessarily slowing down the server.
  • Become aware of high response times in the database. A high response time invariably means a decline in server performance. If this value keeps increasing, you may want to analyze long-running queries.
  • Track disk usage details. Monitoring disk usage statistics is one of the best ways to monitor Postgres servers and analyze if they are functioning efficiently. If this value appears to increase at a rapid pace, this might mean your servers are constantly accessing the storages, effectively slowing down your network. You may need to identify why data retrieval isn't happening from the cache.

Identify queries that contribute to slow performance

Applications Manager's capabilities with Postgres real time monitoring allows you to obtain about Top 10 queries by CPU, long-running queries, and Top 50 table row details. These details help you identify and isolate non-essential queries running in a background process, causing degradation in the performance of the database.

Keep track of sessions

In PostgreSQL, a session can be blocked due to an idle in transaction or due to concurrent access on the same resource or due to some prepared transactions. With Application Manager's Postgresql monitoring software, become aware of blocked sessions.

With the Postgres monitor, identify the number of active sessions and understand which sessions are taking more time, which queries are taking more time and what are they doing, etc.

Optimize database performance by tracking buffer statistics

Applications Manager's Postgres performance monitoring tool gathers data about buffer statistics, providing real-time info on critical Postgres monitoring metrics that can be easily interpreted as valuable insights by database admins.

  • Cache Hit Ratio is the ratio of the number of cache hits to the number of look ups, usually expressed as a percentage. The greater this percentage, the lesser the response time of your database will be.
  • Become aware of block reads/min increasing. This might cause the cache hit ratio to drop as data requested by the queries is retrieved from the disk. You may need to check your cache for unnecessary retention of data.
  • Buffer reads/min indicates the number of cache hits occurring every minute. This gives an overall idea of the efficiency of your database.

Be informed about web transactions occurring in the database

Our extensive Postgres performance monitor tracks details of web transactions occurring in the database. Track the number of commits and rollbacks that occur every minute, thereby allowing you to monitor postgres efficiently. If a large number of these transactions are taking place, you may want to employ backup servers at that time for more availability. If critical transactions are taking place, you can even re-direct the read operations to backup server and perform write/commit operations in the main server to distribute the load.

Detect out-of-sync replicas by monitoring your replication servers

Postgres offers streaming replication service to create a high-availability environment, load-balance read-only queries across several nodes, have a read-only database to run analytical queries on, and more. Sometimes replica can go out of sync too. A Postgres database monitoring tool like Applications Manager enables you to:

  • Detect out-of-sync replicas by gathering information about replication delays.
  • A replication slot keeps track of the last LSN (log sequence number) that its connected replica has received. Every time a replica successfully receives a WAL file, it lets the primary know it can update its LSN. With Applications Manager's Postgres monitoring tool, gather information about replication slots to ensure a primary PostgreSQL instance does not remove WAL files before a replica has received the file.
  • Track the number of scheduled checkpoints and requested checkpoints to ensure low I/O loads.

Monitor postgres database locks

Get real time information about the current locks in the system and catch long-waiting locks. If there are unusually high number of locks resulting in long waits, it can affect the normal behavior of the database. In such situations, developers should review the lines of code that might cause long-held locks such as explicit locking in the application.

Applications Manager's Proactive Postgres DB monitoring capabilities can help you avert critical network issues and prevent large business mishaps, thereby constantly performing proactive Postgres health monitoring to keep your Postgres database at peak performance levels.
