8.1 Monitoring Server Health

Monitoring the health of your server can help prevent it from getting to a state in which your users cannot access the server or the data on it. Novell Remote Manager allows you to monitor the server’s overall health and the health of a specific item.

8.1.1 Viewing the Overall Server Health Status

The server’s overall health is indicated by the color of the circle displayed next to the Server icon Server's health status is good in the header frame for Novell Remote Manager. The following table lists and explains each health status that might be displayed.

Table 8-1 Server Health Status

Server Health Status

Explanation

Good

All parameters included in the server's health configuration list are good.

Suspect

The status of one or more of the parameters included in the server's health configuration list is suspect or has a minor problem.

Bad

The status of one or more of the parameters included in the server's health configuration list is bad or has a critical problem.

Lost connection

The connection to the server from Novell Remote Manager has been lost.

The server’s overall health is determined by services that you configure to be monitored by Nagios.

If the status of any Nagios-monitored service changes to yellow (suspect) or red (bad), the health status indicator light in the header frame changes to indicate there is a problem. If more than one item changes, the worst status indicates the server’s overall status. When the status for all items returns to green (good), then the health light indicator changes back to green (good).

8.1.2 Setting the Health Status Refresh Rate

The server’s health status, reported by the health status indicator, is updated every five seconds, but the graphic refreshes only if the status changes.

  • To modify the refresh rate, select a rate from the Page Refresh Rate drop-down menu, then click Begin Refresh. The selected refresh rate applies to this page only, and persists until you modify the value.

  • To stop refreshing the page, select Stop Refresh. The page does not refresh until you click Begin Refresh.

  • To begin refreshing after stopping, select Begin Refresh. The last used refresh rate is applied automatically when it begins.
