Postgres monitoring scripts

Get to the root cause quickly and resolve costly performance problems. Home PostgreSQL DBA Scripts. POSTGRES allows deferrable foreign keys. That means that a foreign key will be validated only after commiting transaction.


Perl script that runs many different tests against one or more Postgres databases. It uses the psql program to gather the information, and outputs the in one of three formats: Nagios, MRTG, or simple. It was developed with a focus on stored procedure performance but extended well beyond that. Cluu is a Perl-based monitoring solution which uses psql and sar to collect information about Postgres servers and render comprehensive performance stats.


Dash is a comprehensive monitoring solution designed specifically for PostgreSQL deployments. Dash shows you information and metrics about every aspect of your PostgreSQL database server, collected using the open-source tool pgmetrics. A monitoring system will let you know about when, where and why a problem occurred.


With a good optimization and monitoring of ProgreSQL, this database will be suitable even for large companies. Shell scripts that simply monitor the count of files in the pg_wal directory, and send the values to your existing monitoring systems should help you keep track of the WAL file count. Existing script-based tools like check_ postgres can also collect this information.


You should also have a way to correlate this count with the PostgreSQL. Several tools are available for monitoring database activity and analyzing performance. For Oracle I have a number of easy monitoring scripts. For monitoring databases other than Oracle, I have less experience.


I did do work on SQL Server, Sybase and DBwhen working on the development of DB Optimizer but monitoring popular open source databases such as MySQL and Postgres is relatively new to me. Right now I’m looking into Postgres. I personally leverage those via custom site-specific scripts for db admin, upgrade, replication.


That sai there are some other options on the GUI-side beyond pgAdmin: SQL Maestro. With LogicMonitor , you can be comprehensively monitoring all your PostgreSQL databases in minutes. No scripts to install, no libraries to configure, no need to figure out what to monitor.

The user, database, and connection source host items remain the same for the life of the client connection, but the activity indicator changes. The activity can be idle (i.e., waiting for a client command), idle in transaction (waiting for client inside a BEGIN block), or a command type name such as SELECT. GitHub is home to over million developers working together to host and review code, manage projects, and build software together. Monitor and scale a single PostgreSQL server using Azure CLI.


This sample CLI script scales compute and storage for a single Azure Database for PostgreSQL server after querying the metrics. Setting application_name variable in the begging of each transaction allows you to which logical process blocks another one. Convenient SQL for monitoring Postgres database health. Postgres has been stamped on Monday, and will most likely be released this week, so this seems like a good time to review what this new release brings in terms of Monitoring functionality built into the database. In this post, I am sharing few important system or statistics views which we can use for monitoring the PostgreSQL Server.


We should monitor the different statistics of the server which help us for improving the overall database performance. While most PostgreSQL performance monitoring tools monitor the overall database health and availability by executing remote scripts , Applications Manager PostgreSQL monitoring tool offers in-depth Postgres monitoring by collecting metrics such as idle locks that are responsible for the long waits, slow queries, disk and buffer stats such as. While the statistics views give in-depth reporting of database activity at the sql level (particularly pg_stat_activity), monitoring Postgres at the command line is also useful. It allows database information to be integrated with operating system monitoring tools to offer superior analysis about how the database is interacting with system. We tend to prefer the command line over point-and-click.


Several options for monitoring PostgreSQL with nagios. This article will give you several ideas on how to Monitor PostgreSQL with Nagios. Abstract Useful monitoring and metrics views for PostgreSQL Description pgtelemetry is a suite of views, functions and tables which gather and produce a variety of useful metrics for monitoring health of clusters including locks, state of queries, query plans, object size, replication health, and WAL telemetry.


Apart from that, there are few various queries. It is also possible to use the pgstattuple module. My personal favourite is a query by ioguix. Let me show you its output on my test database. SQL Monitoring tools help monitor, optimize and automate day to day database administration and management operations.


They provide database administrators, designers and engineers with knowledge and power to optimize their database systems for optimal business performance in diverse, complex production environments.
