eG Monitoring
 

Measures reported by ClientServiceTest

This test monitors performance as seen by the user of a client desktop from a service perspective. Depending on what servers/ports are configured for monitoring, this test can monitor the performance for user access to Citrix, web, mail and other services. Since this test monitors real user activity from a desktop, rather than simulated activity, the measures of this test are a true reflection of the end user experience. The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Avg_response_time The average time from when a data request is sent by the client to when the server returns a response Secs Comparing this value with the response/connection time at the TCP layer provides an indicator of where the bottleneck is. For example, if the service response time is high but network response is low, this implies that there is a slowdown at the application layers and not in the network.
Max_response_time The maximum response time for requests from the client during the last measurement period Secs  
No_data_responses The number of times during the last measurement period when a data request was sent by the client but a corresponding response was not received from the server Number Ideally, this value should be low.
No_responses_pct The ratio of the number of data requests for which no response was received to the total number of data requests sent during the last measurement period Percent Depending on the nature of the service being accessed, this value should be near zero. A high value indicates potentially that the client is not receiving responses from the servers it is connecting to.
Data_transmits The data transmissions from the client desktop during the last measurement period KB/Sec  
Data_receives The data receptions by the client desktop during the last measurement period KB/Sec  

Note:

For the ClientTcpTest and ClientServiceTest to function smoothly, the eG agent on Windows is bundled with a WinPcap library. WinPcap is the industry-standard tool for link-layer network access in Windows environments: it allows applications to capture and transmit network packets bypassing the protocol stack, and has additional useful features, including kernel-level packet filtering, a network statistics engine and support for remote packet capture. WinPcap consists of a driver, that extends the operating system to provide low-level network access, and a library that is used to easily access the low-level network layers. This library also contains the Windows version of the well known libpcap Unix API. Since the WinPcap library cannot operate on 64-bit environments, the ClientTcpTest and ClientServiceTest will not function on 64-bit Windows clients.
