Device Status Test

For a Cisco-SD WAN appliance to work without a glitch, the four primary components of the Cisco SD-WAN namely, vSmart Controller, vManage, vEgde Routers and vBond Orchestrator should always be up and reachable. If any of the components are down or are not reachable, then, the Cisco SD-WAN appliance may not function as expected or may malfunction. To maintain top-notch functioning of the Cisco SD-WAN appliance, it is necessary to monitor the status and uptime of each component constituting the Cisco SD-WAN appliance. The Device Status test helps administrators in this regard!

This test auto-discovers the components of the target Cisco SD-WAN appliance and for each component, reports the current status and uptime. Besides, this test also reveals whether/not each component is reachable. Using this test, administrators can figure out those components that are frequently in "Abnormal" state and those that are not reachable.

Target of the test : Cisco SD-WAN

Agent deploying the test : An external agent

Outputs of the test : One set of the results for each component of the target Cisco SD-WAN being monitored

Configurable parameters for the test

Parameter	Description
Test period	How often should the test be executed
Host	The IP address of the host for which this test is to be configured.
Port	Specify the port at which the specified Host listens to. By default, this is NULL.
Username	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 this text box.
Password	Specify the password corresponding to the user mentioned in the Username text box here.
Confirm Password	Confirm the Password by retyping it here.
REST API Port	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.
SSL	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.

Measurements made by the test

Measurement	Description	Measurement Unit	Interpretation
Reachability	Indicates whether/not this component is reachable.		The table below indicates the values that this measure can report and their corresponding numeric equivalents: Measure value Numeric Value Unreachable 0 Reachable 1 Note: By default, this measure reports the above-mentioned Measure Values listed in the table to indicate whether/not each component is reachable. The graph of this measure however is represented using the numeric equivalents only.
Status	Indicates the current status of this component.		This measure will be reported only if the value of the Reachability measure is Reachable. The table below indicates the values that this measure can report and their corresponding numeric equivalents: Measure value Numeric Value Abnormal 0 Normal 1 Note: By default, this measure reports the above-mentioned Measure Values listed in the table to indicate whether/not the status of the component is normal. The graph of this measure however is represented using the numeric equivalents only.
Device uptime	Indicates the uptime of this component.	Minutes	This measure will be reported only if the value of the Reachability measure is Reachable.
