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
SSL VPN tunnels	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.	Number
SOCKS method requests received	Indicates the number of requests received through the SOCKS method during the last measurement period.	Number	SOCKet Secure (SOCKS) is an Internet protocol that routes network packets between a client and server through a proxy server.
SOCKS method requests sent	Indicates the number of requests sent through the SOCKS method during the last measurement period.	Number
SOCKS method responses received	Indicates the number of responses received through the SOCKS during the last measurement period.	Number
SOCKS method responses sent	Indicates the number of responses sent through the SOCKS during the last measurement period.	Number
SOCKS connect requests received	Indicates the number of connect requests received through the SOCKS during the last measurement period.	Number
SOCKS connect requests sent:	Indicates the number of connect requests sent through the SOCKS during the last measurement period.	Number
SOCKS connect responses received	Indicates the connect responses received through the SOCKS during the last measurement period.	Number
SOCKS connect responses sent	Indicates the connect responses sent through the SOCKS during the last measurement period.	Number
SOCKS server errors	Indicates the number of server errors received through SOCKS protocol during the last measurement period.	Number	Ideally, this value should be 0.
SOCKS client errors	Indicates the number of client errors received through SOCKS protocol during the last measurement period.	Number
STA connection successes	Indicates the number of successful STA (Secure Ticketing Authority) connections during the last measurement period.	Number	The Secure Ticket Authority (STA) is an XML Web service that exchanges MetaFrame server information for randomly generated tickets. It is used to control access for a Citrix Secure Gateway server.
STA connection failures	Indicates the number of STA connections that failed during the last measurement period.	Number	Ideally, this value should be 0.
CPS connection successes	Indicates the number of successful CPS (Citrix Provisioning Server) connections during the last measurement period.	Number
CPS connection failures	Indicates the number of successful CPS connections during the last measurement period.	Number	Ideally, this value should be 0.
STA requests sent	Indicates the number of STA requests sent during the last measurement period.	Number
STA responses received	Indicates the number of STA responses received during the last measurement period.	Number
ICA license failures	Indicates the number of ICA license failures during the last measurement period.	Number	Ideally, this value should be 0.
