HDX Port Connection Test

This test primarily checks whether the critical TCP ports on the Citrix server are up/down, and reports the responsiveness of each configured port to client requests. For a Citrix server however, these checks might not be adequate at all times; you could have a case where the Citrix server port is up but the server is still not responding. When a connection is made to the Citrix server, it will typically send a message "ICA" to the client. This check connects to the port and then validates the response from the citrix server to see if the ICA stream is being received by the client. Hence, this test additionally reports the ICA connection availability.

Target of the test : A Citrix server

Agent deploying the testn : An external agent

Outputs of the test : One set of results for every configured port name or port number

Configurable parameters for the test
Parameters	Description
Test Period	How often should the test be executed. By default, this is 5 minutes.
Host	The host for which the test is to be configured.
Port	Refers to the port used by the Citrix server.
TargetPorts	Specify either a comma-separated list of port numbers that are to be tested (eg., 1494,1495,1496), or a comma-separated list of port name:port number pairs that are to be tested (eg., ica:1494,smtp:25,mssql:1433). In the latter case, the port name will be displayed in the monitor interface. Alternatively, this parameter can take a comma-separated list of port name:IP address:port number pairs that are to be tested, so as to enable the test to try and connect to Tcp ports on multiple IP addresses. For example, mysql:192.168.0.102:1433,egwebsite:209.15.165.127:80.
Timeout	Here, specify the maximum duration (in seconds) for which the test will wait for a response from the server. The default Timeout period is 60 seconds.
IsPassive	If the value chosen is Yes, then the server under consideration is a passive server in a cluster. No alerts will be generated if the server is not running. Measures will be reported as “Not applicable’ by the agent if the server is not up.

Measurements made by the test
Measurement	Description	Measurement Unit	Interpretation
TCP connection availability	Whether the TCP connection is available or not.	Percent	An availability problem can be caused by different factors – e.g., the server process may not be up, a network problem may exist, or there could be a configuration problem with the DNS server.
Response time	Time taken (in seconds) by the server to respond to a request.	Secs	An increase in response time can be caused by several factors such as a server bottleneck, a configuration problem with the DNS server, a network problem, etc.
ICA connection availability	Indicates whether ICA connection is available or not.	Percent	While the value 100 for this measure indicates that the ICA stream is being received by the client, the value 0 indicates that it is not.
