2 EDB Ark - Overview : 2.1 Architecture Overview : 2.1.3 Monitoring an Ark Cluster with Postgres Enterprise Manager

A PEM installation consists of a PEM server, one or more PEM agents, and the backing database server (named pem). The PEM server includes a web interface that allows you to monitor and manage the database instances that are registered with a PEM agent. A PEM agent is responsible for returning metric information to the PEM server, and performing tasks on the database instances that are registered with that agent.

During deployment, you will be prompted to use the PEM Server Mode drop-down listbox to select a deployment mode:
Select DISABLE to indicate that clusters deployed on the host should not be registered with the PEM server.
Select LOCAL to indicate that you would like to use the PEM server that resides on your local host. If you select LOCAL, the PEM deployment will use default values assigned by the installer.
o
The PEM Server Port will monitor port 5432.
Select REMOTE to indicate that you would like to use a PEM server that resides on another host, and provide connection information on the Ark console deployment dialog (see Figure 2.8).
If you select REMOTE, whenever a new cluster node is created on this console, it will be registered for monitoring by the PEM server.

PEM documentation is available via the PEM web interface Help menu, or at the EnterpriseDB website at:
This feature is implemented before the release of PEM 7.3; until PEM 7.3 is released, the default behavior of Ark is to simply skip installation of the edb-pem-agent rpm and registration of the agent and database servers. When PEM 7.3 is available, Ark 3.0 will automatically install the agent and register cluster nodes with the server. Any currently running nodes will not automatically be updated to register with PEM. To monitor an existing node, you will be required to manually register the node with the PEM server.
