Global Fault Detection
This feature may not be available on all platforms. Please check your system's actual page if your device delivers this feature.
The global fault detection function displays all information that matches the search conditions, which facilitates the viewing of the related information. When there are network issues, you can use the faults such as certain users/groups, certain IPs, or certain applications as the conditions to search all information that relates to the faults. Then you can locate the cause of the faults fast.
To configure the global fault detection settings:
Configure search conditions, including the user/user group, IP address, interface, application, zone, and time.
Click Search to start the search. The search results will be listed in the Configuration tab and Network Service Detection tab.
Configuring Search Conditions
To configure search conditions, take the following steps:
- Select System > Diagnostic Tool > Global Fault Detection.
Configure search conditions as follows.
Select a server from the drop-down list. If the selected AAA server is a local server, select the corresponding user/group from the User/Group drop-down list; if the selected AAA server is not a local server, enter the corresponding username/group name in the blank text box, and then click Add. You can at most configure 3 users/groups.
Enter the IP address, IP address/netmask, or IP address range in the text box, and then click Add. You can at most configure 3 entries. For different IP address, IP address/netmask, or IP address range, separate them with a comma.
Select the interface from the drop-down list. You can at most configure 3 interfaces.
Select the application from the drop-down list. You can at most configure 3 applications or application groups.
Select the zone from the drop-down list. You can at most configure 3 zones.
Select the start time and/or the end time. By default, the system will search the conditions for 1 hour at least. The system can search the information 1 month at most.
- You can set at most 3 search conditions for each condition type.
- For the same condition type, the logical relation between the conditions is OR; for the different condition type, the logical relation between the conditions is AND. If you configure two conditions of the same condition types, for example, IP A and IP B, the search results will list any entry that matches the condition IP A or the condition IP B. If you configure two conditions of different types, IP A and application B, the search results will list the entries that match the condition IP A and the condition application B.
Viewing Search Results
In the Configuration tab, the search results will be listed in the table by category, including the policy, PBR rule, SNAT, DNAT, zone, interface, user/user group, address book, and others. Click the category name, and system jumps to that corresponding module. Users can then view the detailed configurations of each module and configure the settings according to their requirements. If you have filtered time. the results will show you logs in the specified time. If not, system will show you all logs.
In Network Service Detection tab, you can view network nodes, service nodes, historical trend graph of packet loss rate and latency of service/network nodes which satisfy your search requirements.
