The Global Overview Dashboard v8
Upon connecting to Postgres Enterprise Manager, the web interface displays the Global Overview
dashboard. The Global Overview dashboard displays the status of each PEM server and agent, and calls your attention to any triggered alerts on monitored objects.
Use parameters on the PEM Server Configurations dialog to specify the auto-refresh rate for the dashboard. To access the Server Configuration
dialog, select Server Configuration...
from the PEM web interface Management
menu.
