Measures reported by LtmPoolDetailsTest
The Local Traffic Manager can be configured to perform a number of different operations for a load balancing pool such as:
- Associate health monitors with pools and pool members
- Enable or disable SNAT connections
- Rebind a connection to a different pool member if the originally-targeted pool member becomes unavailable
- Specify a load balancing algorithm for a pool
- Set the Quality of Service or Type of Service level within a packet
- ssign pool members to priority groups within a pool
With the help of the load balancing pool, client requests can be evenly distributed across the servers of the pool. Sometimes, the load balancing pools may not be able to handle the client requests owing to performance issues or lack of resources which may inturn cause irregularities in load balancing. To avoid such a situation, you need to monitor the load balancing pools at periodic intervals. The LtmPoolDetailsTest test exactly does the same.
Using this test, administrators can determine the following:
- How well each load balancing pool is handling the data/packet traffic?;
- How many connections are handled by the pool and how many are currently active on the pool?;
- How many connections have been used and how many maximum connections are established in the pool since the start of the traffic manager?
This way, administrators can constantly keep a vigil on the load balancing pool and proactively avoid performance and load balancing issues, if any.
The measures made by this test are as follows:
| Measurement |
Description |
Measurement Unit |
Interpretation |
| Data_transmitted |
Indicates the rate at which data is transmitted from this pool during the last measurement period. |
MB/Sec |
Compare the values of these measures across the pools to identify the pool that is experiencing the maximum traffic. |
| Data_received |
Indicates the rate at which data is received in this pool during the last measurement period. |
MB/Sec |
| Pkts_transmitted |
Indicates the rate at which packets were transmitted from this pool during the last measurement period. |
Packets/Sec |
Compare the values of these measures across the pools to identify the pool that is handling maximum amount of traffic. |
| Pkts_received |
Indicates the rate at which packets were received in this pool during the last measurement period. |
