| Measurement |

Measurement
Unit |
Interpretation |
| Session_count |
The total number of Voyager sessions on the TP machine |
Number |
Ideally, the value of this measure should rise as the load increases, stabilize at target level and decrease when the session timeout period is exceeded. With multiple TPs, look for balanced values. If this is unbalanced, check the routing policy. If this value continues to increase, there could be a problem with garbage collection of expired sessions. |
| New_sessions |
The number of new sessions that have been created in this TP in the past minute |
Number |
If this measure increases with load, and gains stability once peak load has been reached, it is a good sign. If there is no value, or the value suddenly drops, make sure that the web servers are functioning properly. |

The number of sessions which have been garbage collected on this TP in the past minute. Sessions garbage collected include timed out and signed off sessions. |
