Default Parameters for NSTopScrTest

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.

This page depicts the default parameters that need to be configured for the NSTopScrTest.

  • The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

  • This test reports metrics by parsing a Syslog file. Specify the full path to the Syslog file in the LOG FILE PATH text box. To know how to configure the Syslog server where the NetScaler will be creating this file, Click Here.

  • By default, the Syslog file may contain information relating to a number of servers that are inter linked with the target NetScaler appliance. In order to obtain the metrics of the target NetScaler appliance alone, specify the hostname or the IP address of the target NetScaler appliance for which the logs are to be read from the syslog file, in the SEARCH STRING text box. Using this search string the information in the Syslog file may be parsed and metrics may be collected.

  • In the SEARCH STRING INDEX text box, specify the cursor position after which the eG agent should search for the specified SEARCH STRING (or the position upto which the eG agent should ignore while searching for the specified SEARCH STRING) in the syslog file. For example, if the specified SEARCH STRING appears in the syslog file at the 17th position, then you may need to specify the SEARCH STRING INDEX as 16.

  • Specify the number of descriptors that need to be taken into consideration while monitoring the target NetScaler appliance in the REPORT TOP N FLOWS text box. By default, this test will report the Top-10 source IP addresses.

  • The DD FREQUENCY refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD FREQUENCY.

  • Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz” and $port will be changed to “80” when configuring a test.
