Using Summaries

---

Summary graphs and tables provide low-detail representations of performance metrics such as bandwidth consumption, connection failures, usage levels, and critical problems.

Summary graphs and some table entries link to additional details about the relevant item or category.

---

Note You can display certain types of summary information in a detachable dashboard, as described in Understanding Basic Concepts, page 1-3.

---

Table 4-1 describes the options under the Summary tab.

Table 4-1 Performance Monitor Summary Options 

Option	Description	Additional Information
Critical Problems	Select the Critical Problems option to: •Display a table of known critical problems. •Filter problems by problem state. •Acknowledge problems that Performance Monitor discovered in your network.	The Critical Problems option is the default selection when you click the Summary tab. See Working in the Critical Problems Summary.
VPN	Select the VPN option to display performance summary graphs for VPN services.	See Working in the VPN Services Summary.
Firewall	Select the Firewall option to display performance summary graphs for firewall services.	See Working in the Firewall Services Summary.
Load Balancing	Select the Load Balancing option to display performance summary graphs for content-switching services.	See Working in the Load-Balancing Summary.
SSL	Select the SSL option to display performance summary graphs for SSL proxy services.	See Working in the SSL Services Summary.
Event Browser	Select the Event Browser option to open an Event Browser window with no preset filters.	See Working in an Event Browser, page 3-12.

Working in the Critical Problems Summary

A critical problem has a severity level of either P1 or P2. You can display the known critical problems for all monitored services in your network.

Procedure

---

Step 1 Select Summary > Critical Problems.

Step 2 Complete the optional tasks that meet your requirements (Table 4-2).

The refreshed display shows the result of any optional task that you complete.

---

Table 4-2 Optional Tasks in the Critical Problems Page 

Optional Task	Procedure	Additional Information
Note Table 3-3 on page 3-9 describes additional optional tasks.
Set a filter that changes the displayed content.	Select a problem state (e.g., Acknowledged) from the Select Status list.	The refreshed list shows only monitored problems in the specified state. If no problems match the specified state, the refreshed list contains no records.
Open an Event Browser window and display a filtered list of all events on a specific device.	Click a hyperlinked entry in the Description column.	The Event Browser display is not limited to the P1 and P2 severity levels, as the Critical Problems page is. Therefore, the Event Browser might display events of any or every severity level for the device you specify.
Acknowledge a critical problem.	Select the check box in the row that describes the problem to resolve, then click Acknowledge.	Only one user can acknowledge any specific problem. When you acknowledge a problem, you accept responsibility for resolving it. Note There is no undo function by which you can decline to resolve a problem that you have acknowledged.

Working in the VPN Services Summary

Performance Monitor provides graphs that summarize the condition of remote access and site-to-site VPN services in your network.

Click to open an Event Browser and display severe RAS errors only.
Top 3 User Session Count	Shows real-time session counts for the three devices with the most user sessions. If fewer than three devices have user sessions, there are fewer than three bars in the chart. If there are no user sessions on any of your RAS devices, the chart is empty. Click to display the Remote Access Devices page, which shows performance statistics for your RAS devices individually.

If you have fewer than three site-to-site devices in your network, there are fewer than three bars in the chart. If there is no throughput on any of your site-to-site devices, the chart is empty. Click to display the Site-to-Site Devices page, which shows performance statistics for your site-to-site devices individually.
Top 3 Connection Failures %	Shows real-time connection failures of the three site-to-site devices that are experiencing the most connection failures. If you have fewer than three site-to-site devices in your network, there are fewer than three bars in the chart. If there are no failed connections on any of your site-to-site devices, the chart is empty. Click to open an Event Browser and display severe site-to-site errors only.
Top 3 Tunnel Count	Shows real-time tunnel counts for the three devices with the most tunnels. If you have fewer than three site-to-site devices in your network, there are fewer than three bars in the chart. If there are no tunnels on any of your site-to-site devices, the chart is empty.
