Measures reported by LBL4RSTest
Real servers are those that are bound to a virtual server in a server farm of the load balancer. Whenever a client request is received, the virtual server bound to the real server responds to those requests by channelizing the requests to the real servers that are currently available. If the real servers are experiencing any technical glitch or a slowdown or if the real servers are currently overloaded, the target load balancer may not be effective in responding to the client requests thus causing inconsistencies in the load balancing functionality. To avoid such inconsistencies, it is necessary to monitor the request processing ability of the real servers round the clock. This is where the LBL4RSTest test exactly helps!
For each real server grouped on the virtual server that is configured on the target load balancer, this test reveals how well each server processes client requests. In addition, this test detects inconsistencies in load-balancing early on and warns administrators of possible deviations proactively.
Outputs of the test : One set of results for each Virtual server:Real server combination on the target load balancer being monitored.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| curCon |
Indicates the number of connections handled by this real server during the last measurement period. |
Number |
This measure is a good indicator of load on the real server.
The detailed diagnosis of this measure lists the IP address and the port number of the real server through which the server is associated with the virtual server. |
| rsInPkt |
Indicates the number of packets received by this real server during the last measurement period. |
Number |
Compare the value of this measure across the real servers to figure out the real server that is receiving the maximum number of packets. |
| rsOutPkt |
Indicates the number of packets transmitted by this real server during the last measurement period. |
Number |
Compare the value of this measure across the real servers to figure out the real server that is transmitting the maximum number of packets. |
| rsInData |
Indicates the amount of data received by this real server during the last measurement period. |
KB |
Compare the value of this measure across the real servers to figure out the real server that is receiving the maximum amount of data. |
| rsOutData |
Indicates the amount of data transmitted by this real server during the last measurement period. |
