Note:
By default, this measure reports one of the Measure Values listed in the table above to indicate the health of this service group member. In the graph of this measure however, the health of the service group member will be represented using the numeric equivalents. |
| Data_transmitted |
Indicates the rate at which data was transmitted from this service group member during the last measurement period. |
MB/Sec |
Compare the values of these measures across service group members to identify the member that is handling maximum traffic. |
| Data_received |
Indicates the rate at which data was received by this service group member during the last measurement period. |
MB/Sec |
| Packets_transmitted |
Indicates the rate at which the packets were transmitted from this service group member during the last measurement period. |
Packets/Sec |
Compare the value of these measures across the service group members to identify the member that is experiencing the maximum traffic. |
| Packets_received |
Indicates the rate at which packets were received by this service group member during the last measurement period. |
Packets/Sec |
| Curr_connections |
Indicates the number of connections currently active between this service group member and the A10 Aplication Delivery Controller. |
Number |
This measure is a good indicator of the load on the service group member. |
| Tot_connections |
Indicates the number of connections that are currently active on this service group member. |
Number |
|
| Connection_rate |
Indicates the rate at which the connections were established on this service group member during the last measurement period. |
Conns/Sec |
A sudden increase in the value of this measure indicates an increase in the load on the service group member. |
| Conn_usage |
Indicates the percentage of connections used by this service group member. |
Percent |
A value close to 100% indicates that this service group membert is currently overloaded. |
| Persistent_conns |
Indicates the number of connections that were persistent on this service group member. |
Number |
TCP connections that are kept open after transactions complete are called persistent connections. Persistent connections stay open across transactions, until either the client or the server decides to close them. These connections when reused can significantly reduce the overload on the new connections to the service group member. |
| Peak_conns |
Indicates the maximum number of connections that were established on this service group member since the start of the A10 Application Delivery Controller. |
Number |
|
| Curr_L7_requests |
Indicates the number of L7 requests currently processed in this service group member. |
Number |
Both these measures serve as effective pointers to the L7 requests processing in the A10 Application Delivery Controller.
Layer-7 load balancing, also known as application-level load balancing, is to parse L7 requests in application layer and distribute L7 requests to the servers based on different types of request content, so that it can provide quality of service requirements for different types of content and improve overall performance of the A10 Application Delivery Controller. |
| Tot_L7_requests |
Indicates the total number of L7 requests processed by this service group member during the last measurement period. |
Requests/Sec |
| Succ_L7_requests |
Indicates the number of L7 requests that were processed successfully by this service group member. |
Number |
Ideally, value of this measure should be high. |
