Measures reported by CpsLBSrvrStTest

The real test of the efficiency of a load balancer lies in its ability to uniformly distribute load across the servers in a cluster, thereby ensuring the peak performance and continuous availability of the dependent services. Using the CpsLBSrvrStTest test, administrators can accurately judge the efficiency and effectiveness of the load balancer.

This test monitors the connections, data traffic and compressed HTTP responses on each server in a cluster, promptly detects load imbalances, and alerts administrators to them, so that they can quickly resolve the issue.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Server_status_tot_conns Indicates the total number of connections to this server. Number If a sudden/consistent increase in the value of this measure is noticed, you might have to investigate further to identify the reason for this occurrence.
Server_status_active_con Indicates the number of connections that are currently active for this server. Number A high value is desired for this measure. This indicates the connection load on the server. By observing the graph of this measure over time, you can analyze the rate of growth of the load on the server. By comparing the value of this measure across all the servers in a cluster, you can instantly identify overloaded servers; this in turn brings irregularities in load balancing to light.
Server_conn_usage Indicates the percentage of connections that are currently used by this server. Percent A high value is desired for this measure. This measure is the percentage ratio of Server_status_active_con mesure to the Server_status_tot_conns measure.
Server_status_tot_trans Indicates the total number of transactions processed by this server. Number  
Server_status_receive Indicates the amount of data received by this server. KB Comparing the value of these measures across the servers will help you identify the server that is most busy in transmitting/receiving the data. This in turn, helps the administrators to determine the load on the server.
Server_status_sent Indicates the amount of data transmitted through this server. KB
Server_status_cur_comp Indicates the number of HTTP responses that were compressed by this server. Number  
Server_status_tot_comp Indicates the number of HTTP responses that were compressed by this server since the start of the Coyote Load Balancer. Number
