Default Monitoring Configurations
Postgresql application has default Global Device Management Policies, Global Templates, Global Monitors and Global Metrics in OpsRamp. You can customize these default monitoring configurations as per your business requirement by cloning respective Global Templates and Global Device Management Policies. It is recommended to clone them before installing the application to avoid noise alerts and data.
Default Global Device Management Policies
You can find the Device Management Policy for each Native Type at Setup > Resources > Device Management Policies. Search with suggested names in global scope:
{appName nativeType - version}Ex: postgresql-cluster PostgreSql Node - 1 (i.e, appName = postgresql-cluster, nativeType = PostgreSql Node, version = 1)
Default Global Templates
You can find the Global Templates for each Native Type at Setup > Monitoring > Templates. Search with suggested names in global scope. Each template adheres to the following naming convention:
{appName nativeType 'Template' - version}Ex: postgresql-cluster PostgreSql Node Template - 1 (i.e, appName = postgresql-cluster, nativeType = PostgreSql Node, version = 1)
Default Global Monitors
You can find the Global Monitors for each Native Type at Setup > Monitoring > Monitors. Search with suggested names in global scope. Each Monitors adheres to the following naming convention:
{monitorKey appName nativeType - version}Ex: PostgreSql Node Monitor postgresql-cluster PostgreSql Node 1 (i.e, monitorKey = PostgreSql Node Monitor, appName = postgresql-cluster, nativeType = PostgreSql Node, version = 1)
