TMM Memory Threshold

Hi,

i need to monitor the TMM memory usage metric for these appliances:

- 1 i5800 - 48 GB DDR4 - 8 CPU
- 1 5250 - 32 GB - 8 CPU
- 1 i2800 - 16 GB DDR4 - 4 CPU

The first two are in vCMP mode. The i5800 model has three vCMP istances, the 5250 has 2 vCMP istances. I need to know which are the recommended values for the TMM memory usage metric in order to set a threshold.

Thanks in advance.

TMM will start close connection when reaches 85%, and stop new connections when it reached 95%. TMM would not use more than is allocated to it, so would not use the swap memory. You can configure any value between 70 to 80 for your threshold.
