Tracking the login status of the network elements on a TL1 device

For most TL1 devices, there are multiple monitored devices (TIDs) for each connection to a gateway network element. These connections are configured using the hosts file specified by the HostsFile property. It is common for a TL1 hosts file to configure up to 30 TIDs on a single connection, each of which requires a login (chat-in) string.

The probe tracks the login status of each TID. When the probe logs in to a TID, it writes a Login Successful ProbeWatch message to its message log. If the login fails to a single TID, whether due to a DENY response or a timeout, the TL1 probe writes a Login Failed ProbeWatch message to its message log and then moves on to the next TID on the TL1 device.

The probe will retry the failed TID connection when it has tried all the other TIDs defined for the TL1 device. It will continue to retry the connection until successful, whereupon it writes a Login Successful ProbeWatch message to its message log.
