Measures reported by CpsClstrStatusTest

The Equalizer typically manages traffic to a group of servers in a server farm. While the servers in a farm can still be individually accessed, all traffic to the servers will be directed to a separate IP address, called a Virtual Cluster. The Virtual Cluster will accept traffic and distribute it to the available servers. An Equalizer can be configured to manage multiple server farms/clusters. To be able to accurately assess the workload of the equalizer, you need to have a fair idea of the connection and data load on each of the clusters it manages. The Equalizer Cluster Status test enables you to ascertain the same. For each cluster, this test reports the current load on the cluster and indicates how busy the servers in the cluster are.

Reports the current load on the cluster and indicates how busy the servers in the cluster are.

 The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Cluster_load Indicates the calculated load value for this cluster. Number This serves as a good indicator of the cluster workload. Comparing the value of this measure across clusters will enable you to identify those clusters that are overloaded.
Current_connections Indicates the number of connections currently active on this cluster. Number This again serves as a good indicator of the cluster workload.
Total_connections Indicates the total number of connections handled by this cluster. Number  
Throughput Indicates the rate of data traffic handled by this cluster over the last second. MB/sec  
Hit_rate Indicates the rate at which servers in this cluster were accessed for performing transactions. Mbps Comparing the value of this measure across clusters will enable you to quickly spot the busiest clusters.
