15.4.2. The Server Graphs and Critical Events

The center of the Monitor page gives a visual representation of the state of your servers.

The graphs present information about the currently selected server or server group. The default graphs show the hit ratios, CPU utilization, connections, and database activity for a specific interval.

To set the interval click the configure graphs link immediately below the graphs. This opens a dialog box where you can choose the default interval for the x-axis of the graphs. Defining a shorter or longer interval gives you a shorter or longer term view of server activity. The thumbnail and full-size graph dimensions can also be adjusted from this dialog box. Save any changes that you have made and the values chosen will be the defaults whenever you log in.

You can also choose the default graphs shown on the Monitor page. To do this click the edit favorites link and choose the graphs you want from the drop-down list box. To choose contiguous graphs, hold down the Shift key and click on the desired graphs. For a noncontiguous selection, click the desired graphs while holding down the Ctrl key. The maximum number of graphs that can be displayed on the Monitor page is six. Save your changes and these will be the default graphs whenever you log in.

Color coding helps distinguish different aspects of each graph. With Database Activity for example, you can readily distinguish SELECT statements from database insertions.

Clicking a graph opens a detailed view with Graph Display and Configure tabs. Choose the Configure tab to temporarily change the way that a graph displays. Changes made from this tab only apply to the standalone graph while it is open. Persistent changes are made as described above.

Dismiss the enlarged graph by clicking the hide button.

Critical alerts appear on this page immediately below the graphs–quickly attracting your attention. For a description of all the different alarm levels see, Section 15.4.3, “The Heat Chart”. This is the subject of discussion in Section 15.7, “The Events Page”.
