PostgreSQL Monitoring User Guide


PostgreSQL monitoring is a Gateway configuration file that enables monitoring of Postgresql database installation through the SQL Toolkit plug-in.

This integration template allows monitoring of queries, views, triggers in the Gateway set-up, and other server activities, such as:

  • Tracking of command being executed in the server.
  • Monitoring of information about table and index dataview.
  • Permits user-defined functions.

To view the sample metrics and dataviews, see PostgreSQL Monitoring Technical Reference.

Intended audience

This guide is intended for users who are setting up, configuring, troubleshooting and maintaining this integration. Once the integration is set up, the samplers providing the dataviews become available to that Gateway.

As a user, you should be familiar with SQL or any other database, and with the administration of the PostgreSQL services.


The following requirements must be met prior to the installation and setup of the template:

  • A machine running the Netprobe must have access to the host where the PostgreSQL instance is installed and the port PostgreSQL is listening to.
  • Netprobe 4.6 or higher.
  • Gateway 4.8 or higher.
  • PostgreSQL 9.6.

Installation procedure

Ensure that you have read and can follow the system requirements prior to installation and setup of this integration template.

  1. Download the integration package geneos-integration-postgresql-<version>.zip from the ITRS Downloads site.
  2. Open Gateway Setup Editor.
  3. In the Navigation panel, click Includes to create a new file.
  4. Enter the location of the file to include in the Location field. In this example, it is the include/PostgreSQLMonitoring.xml.
  5. Update the Priority field. This can be any value except 1. If you input a priority of 1, the Gateway Setup Editor returns an error.
  6. Expand the file location in the Include section.
  7. Select Click to load.
  8. Click Yes to load the new Postgresql include file.
  9. Click Managed entities in the Navigation panel.
  10. Add the Postgresql type to the Managed Entity section that you will use to monitor Postgresql.
  11. Click Validate current document to check your configuration.
  12. Click Save current document to apply the changes.

Set up the samplers

These are the pre-configured samplers available to use in PostgresqlMonitoring.xml.

Configure the required fields by referring to the table below:

Active Locks

Set up the variables

The PostgresqlMonitoring.xml template provides the variables that are set in the Environments section:

Samplers Description
PSQL_SERVER_NAME IP/Hostname where the Postgresql installation resides.
PSQL_PORT Assigned port in the Postgresql service.
  • pg_stat_user_tables
  • pg_stat_user_indexes
  • pg_statio_user_tables
  • pg_class
  • pg_namespace
  • pg_stat_bgwriter
  • pg_stat_database
  • pg_locks
  • pg_database
  • pg_stat_activity
Username with the rights to access the following tables.
PSQL_PASSWORD Password of the database user.

Database names:

  • Server Specific Metrics uses the default database Postgresql.
  • Database Specific Metrics specifies the actual database to monitor.

Set up the rules

The PostgresqlMonitoring-SampleRules.xml template also provides a separate sample rules that you can use to configure the Gateway Setup Editor.

Your configuration rules must be set in the Includes section.

If a rule has a critical and warning variable, you must configure it both to activate the rule:

Variables Critical Warning
Checkpoint - Checkpoint Requests : Checks the ratio of checkpoints requested vs. scheduled checkpoints PSQL_CHECKPOINT_SCHEDULED_CRITICAL:
Possible values 1.0 - 100.0
Possible values 1.0 - 100.0
Database-Statistics - Commit Ratio : Checks the ratio between transactions committed vs rolledback PSQL_COMMIT_RATIO_CRITICAL:
Possible values 1.0 - 100.0
Possible values 1.0 - 100.0
Database-Statistics - Connection utilisation : Rule that checks the connections used expressed in percentage compared to max_connections PSQL_CONNECTIONS_CRITICAL:
Possible values 1.0 - 100.0
Possible values 1.0 - 100.0
Database-Statistics - Deadlocks : Checks for deadlocks PSQL_DEADLOCK_RATIO_CRITICAL:
Integer value
Integer value
Processes - Long Running Queries : Checks the duration of query execution PSQL_QUERY_EXECUTION_THRESHOLD_IN_SECS_CRITICAL:
Integer value
Integer value
Replication - Delay : Checks for delays in replication PSQL_REPLICATION_DELAY_CRITICAL:
Integer value. Time in seconds
Integer value. Time in seconds
Checkpoint - Written Buffers Checkpoint : Checks the ratio of dirty buffers written by checkpoint vs bgwriter plus backends PSQL_WRITTEN_BUFFERS_CRITICAL:
Possible values 1.0 - 100.0
Possible values 1.0 - 100.0
Database-Statistics - Size Threshold : Checks the size of the databases in the currently monitored server PSQL_DATABASE_SIZE_CRITICAL:
Possible values - XXX kB, XXX MB, XXX GB and XXX TB
Not applicable

Note: The sample configuration file was verified working with Postgresql 9.6 and Netprobe 4.5 versions.
