Measures reported by NSTopScrTest

In environments where the NetScaler appliance is deployed, external clients (Source IPs) communicate via the NetScaler appliance to access applications hosted on the servers (Destination IPs). The NetScaler appliance is deployed in front of the web or database servers and routes requests to the servers from the external clients through it. When multiple clients are sending requests to the servers through the NetScaler device, it is impossible for the administrators to keep track of which client is sending the maximum amount of data to the server through its requests. In order to identify the topmost clients who are contributing to the maximum data transfer between the client and the server, adminsitrators can use the NSTopScrTest test.

This test dynamically lists the top clients and for each client reports the amount of data sent from the client to the server and amount of data received by the client from the server. By comparing the measures reported by this test, administrators can identify the topmost client in terms of data transfer.

For this test to run and report metrics, the NetScaler device should be configured to create a Syslog file in a remote Syslog server, where the details of all interactions with the NetScaler appliance will be logged.

Outputs of the test : One set of results for each Source IP address configured on the target Citrix NetScaler

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
source_byte_sent Indicates the total amount of data sent from this client (source IP) to the server (destination IP). KB Compare the value of this measure across the source IP addresses to know which source IP address is sending the maximum amount of data.

The detailed diagnosis of this measure if enabled, lists the Source IP, Destination IP, Start time, End Time, Total Bytes sent and Total Bytes received.
source_byte_recv Indicates the total amount of data received by this client (source IP) from the server (destination IP). KB Compare the value of this measure across the source IP addresses to know which source IP address is receiving the maximum amount of data.

The detailed diagnosis of this measure if enabled, lists the Source IP, Destination IP, Start time, End Time, Total Bytes sent and Total Bytes received.
