Configuration of CisSDWCrashTest

This test reports the number of times each component of the target Cisco SD-WAN appliance crashed. The detailed diagnosis of this test will help administrators figure out the time during which the crash occurred and the name of the crash file. Using this test, administrators can analyze the reason behind such crashes and rectify issues before end users start complaining of frequent failures on the overlay network.

The default parameters associated with this test are as follows:

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• In the HOST text box, the host for which the test is to be configured has to be specified.

• In the PORT text box, enter the port number at which the target host being monitored listens. By default, this is set to NULL.

• By default, the eG agent executes REST APIs on the target appliance to collect the required metrics. For the eG agent to execute the REST APIs, a special user with monitoring privilege is required. Specify the name of such a user in the USERNAME text box.

• Specify the password corresponding to the user mentioned in the USERNAME text box here.

• Confirm the Password by retyping it here.

• By default, the REST API Port is set to none. This implies that by default, this test connects to the default port to execute the REST API commands and collect the required metrics. In some environments however, a different port can be used to execute the REST API commands. In such case, specify that port number against the REST API PORT text box.

• The eG agent collects performance metrics by executing REST APIs on the target appliance. Typically, the REST APIs can be invoked through HTTP or HTTPS mode. By default, the eG agent invokes REST APIs using the HTTPS mode. This is why, the SSL flag is set to Yes by default. If the target appliance is not SSL-enabled, then the REST APIs can be accessed through HTTP mode only. In this case, set the SSL flag to No.

• To make diagnosis more efficient and accurate, the eG suite embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the DETAILED DIAGNOSIS capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option.

  The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled:

  • The eG manager license should allow the detailed diagnosis capability.

  • Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

• Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of “none” in the parameter value indicates that the corresponding parameter value can be changed if required.
