VPN Test

This test monitors VPN sessions and reports errors in the sessions.

Target of the test : An ADC VPX/MPX

Agent deploying the test : A remote agent

Outputs of the test : One set of results for the ADC appliance 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 the test is being configured.

NetScaler Username and NetScaler Password

To monitor a ADC device, the eG agent should be configured with the credentials of a user with read-only privileges to the target ADC device. Specify the credentials of such a user in the NetScaler Username and NetScaler Password text boxes.

Confirm Password

Confirm the ADC Password by retyping it here.

SSL

The eG agent collects performance metrics by invoking NITRO (ADC Interface Through Restful interfaces and Objects) APIs on the target ADC device. Typically, the NITRO APIs can be invoked through the HTTP or the HTTPS mode. By default, the eG agent invokes the NITRO APIs using the HTTPS mode. This is why, the SSL flag is set to Yes by default. If the target ADC device is not SSL-enabled, then the NITRO APIs can be accessed through the HTTP mode only. In this case, set the SSL flag to No.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Login page requests received

Indicates the number of VPN login requests received during the last meaurement period.

Number

 

Login page delivery failures

Indicates the number of times the VPN login page failed to be displayed during the last measuement period.

Number

Ideally, the value should be 0.

Client configuration requests received

Indicates the number of client configuration requests received by the VPN server during the last measurement period.

Number

 

DNS queries resolved:

Indicates the number of DNS queries resolved by the VPN server during the last measurement period.

Number

 

WINS queries resolved

Indicates the number of WINS queries resolved by the VPN server during the last measurement period.

Number

Indicates the number of SSL VPN tunnels formed between the VPN server and the client during the last measurement period.

Number

 

Backend HTTP server probes

Indicates the number of probes from the VPN server to the Back-end HTTP servers that have been accessed by the VPN client during the last measurement period.

Number

 

Backend Non-HTTP server probes

Indicates the number of probes from the VPN server to the Back-end non-HTTP servers that have been accessed by the VPN client during the last measurement period.

Number

 

Backend server probe successes

Indicates the number of probes that were successful on all the Back-end servers during the last measurement period.

Number

 

File system requests received:

Indicates the number of file system requests received by the VPN server during the last measurement period.

Number

 

Number of times MIP used and IIP disabled

Indicates the number of times the Mapped IP (MIP) was used in lieu of the Intranet IP (IIP) that was disabled during the last measurement period.

Number

 

Number of times MIP used and IIP failed

Indicates the number of times the MIP was used in lieu of the IIP as the IIP assignment failed during the last measurement period.

Number

 

Number of times MIP used and IIP spillover

Indicates the number of times the MIP was used on the IIP spillover during the last measurement period.

Number

When IP pooling is configured and the mapped IP is used as an intranet IP address, the mapped IP address is used when an intranet IP address cannot be assigned. This process is termed as a Spillover.

Both MIP and IIP disabled

Indicates the number of times both the MIP and the IIP was disabled during the last measurement period.

Number

 

Number of times IIP failed and MIP disabled:

Indicates the number of times the IIP assignment failed with the MIP was disabled during the last measurement period.
