Control Host Statistics

MaaS monitors the health and performance of your TMedia host servers and individual application processes. For 1+1 redundant deployments, each host is monitored separately with role identification.

Understanding HA States

For 1+1 redundant deployments, application HA states indicate:

State	Meaning
Active	Application is handling traffic
Standby	Application is ready for failover
Initialized	Application has started and is coming online
Ready	Application is operational but not yet carrying traffic
Not Present	Application is not installed or not expected on this host
Not Ready	Application is not in a ready state

Core Application HA Tracking

MaaS tracks Core Application HA — the HA state of the applications that actually carry your traffic (gateway, tbsip, tbrouter, and others). When any of these flips between Active and Standby, a Core Application Switchover notification fires so your team knows traffic has moved units.

This is distinct from generic App State — a process can be running (App State = Up) while still being Standby. Core App HA tells you which unit is actually handling calls.

HA Failover Behavior

In a 1+1 deployment, MaaS monitors both hosts independently. During a failover:

• The previously Active host transitions applications to Standby or Not Ready

• The previously Standby host transitions applications to Active

• MaaS continues monitoring both hosts throughout the transition

• A Core Application Switchover notification is sent

Monitor the standby host — issues there will become problems during failover.

Troubleshooting

1

High Host CPU

Check per-application CPU to identify the culprit. Common causes include high call volume, media transcoding, and logging overhead.

2

High RAM Usage

Memory issues may indicate memory leaks (check application states), insufficient resources for call volume, or logging/caching issues.

3

Disk Space Issues

Common causes of disk space consumption: CDR/log accumulation, core dumps, and signaling traces.
