Measures reported by PsClassDataTest
In order to analyze or control one type of traffic distinctly, PacketShaper load balancer must be able to differentiate it from other types of traffic. The traffic tree's traffic classes are PacketShaper's mechanism for identifying and organizing different types of traffic. A traffic class is the logical grouping of the traffic flow that share common characteristics and are analyzed or controlled together.
Once a traffic class is created, it is a good practice to observe the data flow to and from each traffic class, so that you can check the effectiveness of the rules and policies that you have set per traffic class for regulating the data flow. This is where the PsClassDataTest test helps.
This test auto-discovers the traffic classes configured in the target load balancer, monitors the amount of high order and low order data sent and received by each traffic class and captures data drops. In addition, this test also reveals the amount of compressed/non-compressed data sent/received by each traffic class.
Outputs of the test : One set of results for each traffic class defined on the target PacketShaper Load Balancer that is to be monitored.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| current_rate |
Indicates the rate at which this class is currently handling the data flow. |
Kbps |
This measure is an good indicator of bandwidth usage of each traffic class |
| Low_order_byte_count |
Indicates the amount of low order data transferred using this class during the last measurement period. |
KB |
|
| High_order_byte_count |
Indicates the amount of high order data transferred by this class during the last measurement period. |
KB |
|
| Low_order_byte_rexmit |
Indicates the amount of low order data retransmitted using this class during the last measurement period. |
KB |
|
| High_order_byte_rexmit |
Indicates the amount of high order data retransmitted using this class during the last measurement period. |
KB |
|
| Low_order_byte_drop |
Indicates the amount of late low order data dropped while transmitting the data using this class during the last measurement period. |
KB |
A low value is desired for this measures. |
| High_order_byte_drop |
Indicates the amount of late high order data dropped while transmitting the data using this class
during the last measurement period. |
KB |
A low value is desired for this measures. |
| Non_compress_bytes |
Indicates the amount of non-compressed data transmitted using this class during the last measurement period. |
KB |
|
| High_order_byte_noncompress |
Indicates the amount of non-compressed high order data transferred using this class during the last
measurement period. |
KB |
|
| before_compress_bytes |
Indicates the amount of data received using this class before compression during the last measurement period. |
KB |
|
| High_order_byte_beforecompress |
Indicates the amount of high order data received using this class before compression during the
last measurement period. |
KB |
|
| after_compress_bytes |

KB |
|
| High_order_byte_aftercompress |
