Global System Statistics

Global statistics aggregate call metrics across your entire TMedia system, regardless of NAP or protocol. These provide a system-wide view of traffic, licensing, and configuration status.

Real-Time Call Metrics

These metrics show the current state of calls on the system:

Statistic	Units	Description
Active Calls	Calls	Currently connected/active call count
Call Legs	Call Legs	Total call legs (typically 2 per call)
Non-Active Call Legs	Call Legs	Call legs in setup/teardown (calculated)
Incoming Call Legs	Call Legs	Current inbound call legs
Outgoing Call Legs	Call Legs	Current outbound call legs

---

Call License Usage

Statistic	Units	Description
Call License Usage	Call Legs	Current call legs measured against license limit

Call License Usage tracks your active call legs relative to your licensed session capacity. Alerts trigger when usage approaches or exceeds the limit.

---

Call Counters

Cumulative counters that increment with each call. MaaS calculates the delta between polling intervals to show calls per interval.

Total Call Counters

Statistic	Direction	Description
Call Count	All	Total calls since system restart
Incoming Call Count	Incoming	Inbound calls since restart
Outgoing Call Count	Outgoing	Outbound calls since restart

Accepted Call Counters

Calls that were successfully accepted by the system:

Statistic	Direction	Description
Accepted Call Count	All	Successfully accepted calls
Incoming Accepted	Incoming	Inbound accepted calls
Outgoing Accepted	Outgoing	Outbound accepted calls

Answered Call Counters

Calls that reached the answered/connected state:

Statistic	Direction	Description
Answered Call Count	All	Connected/answered calls
Incoming Answered	Incoming	Inbound answered calls
Outgoing Answered	Outgoing	Outbound answered calls

---

Calls Per Second (CPS)

CPS metrics are calculated from the cumulative counters, showing the rate of calls over time.

Overall CPS

Statistic	Direction	Description
CPS	All	Overall call attempt rate
Incoming CPS	Incoming	Inbound call rate
Outgoing CPS	Outgoing	Outbound call rate

Accepted CPS

Statistic	Direction	Description
Accepted CPS	All	Rate of accepted calls
Incoming Accepted CPS	Incoming	Inbound accepted rate
Outgoing Accepted CPS	Outgoing	Outbound accepted rate

Answered CPS

Statistic	Direction	Description
Answered CPS	All	Rate of answered calls
Incoming Answered CPS	Incoming	Inbound answered rate
Outgoing Answered CPS	Outgoing	Outbound answered rate

CPS metrics help identify peak traffic periods, sudden spikes, and trends over time — useful for capacity planning and spotting issues.

Configuration Backup

MaaS monitors the active configuration backup status on your system and alerts on changes or failures.

Statistic	Type	Description
Active Configuration Backup	Status	Current state of the active configuration backup process

---

Alerts

High Severity

Alert	Condition	Description
MaaS Call Limit Exceeded	Active call legs exceed MaaS service limit	Call volume has surpassed the MaaS monitoring service limit
License Limit in Danger	Call legs approaching licensed capacity	Active call legs are critically close to the license maximum

Warning Severity

Alert	Condition	Description
Nearing Call License Limit	Call legs over 80% of licensed capacity	Active call legs are approaching the license maximum
Backup Configuration Failed	Configuration backup process failed	The system was unable to complete a configuration backup

Information Severity

Alert	Condition	Description
MaaS Call Limit over 90%	Active call legs over 90% of MaaS limit	Call volume is approaching the MaaS monitoring service limit
Active Configuration Changed	Active configuration hash changed	A change to the active configuration was detected. Fires only on an actual config change — previously could false-fire on heartbeat.
Configuration Successfully Received	Configuration backup completed	A configuration backup was successfully received (nightly)

Understanding the Metrics

Active Calls vs Call Legs

• Active Calls: The number of currently connected conversations

• Call Legs: Each call typically has 2 legs (inbound + outbound), so Call Legs ≈ Active Calls × 2

• Non-Active Call Legs: Calls in setup, alerting, or teardown phases

Accepted vs Answered

• Accepted: The system accepted the call attempt (passed initial validation)

• Answered: The call reached a connected state (far end picked up)

The ratio of Answered to Accepted can indicate network quality issues or routing problems.

Using CPS for Capacity Planning

CPS metrics help identify:

• Peak traffic periods for capacity planning

• Sudden traffic spikes that may indicate issues

• Traffic trends over time when viewed historically

MaaS Call Limit vs License Limit

• MaaS Call Limit: The maximum number of call legs the MaaS monitoring service is configured to track. This is a service-level limit, not a hardware limit.

• License Limit: The maximum number of concurrent call legs your TMedia system is licensed to handle.

These are independent limits — you may hit one before the other depending on your deployment size and service plan.
