By default only ten entries are displayed in a view. You can choose the number of entries to be displayed under the Show entries drop down box. Click  to expand the window to display more fields.

The following fields are displayed:

System Congestion Current Statistics Parameters

ParameterDescription
NameThe name of the CE Node.
Level MC1CountThe number of transitions into MC1 since the current interval started.
Level MC1Total Time The sum of time spent in MC1 since the current interval started.
Level MC2Count The number of transitions into MC2 since the current interval started.
Level MC2Total Time The sum of time spent in MC2 since the current interval started.
Level MC3CountThe number of transitions into MC3 since the current interval started.
Level MC3Total Time The sum of time spent in MC3 since the current interval started.
Overload RejectsThe number of calls rejected due to system congestion since the current interval started.
Avg Call Rate The average call rate calculated using the formula: (# call attempts in an interval) / (# seconds elapsed in that interval).
Peak Call RateThe system peak call arrival rate since the current interval started.
Call ArrivalsThe number of call arrivals since the current interval started.
Emergency Call Arrivals The number of SIP emergency call arrivals since the current interval started.
Emergency Call Rejects The number of SIP emergency call rejects since the current interval started.
SIP Register ArrivalsThe number of SIP registrations arrivals since the current interval started.
SIP Register Rejects The  number of SIP registrations rejected since the current interval started.
Avg Register Rate The average registration rate calculated using the formula: (# registration attempts in an interval) / (# seconds elapsed in that interval).
Peak Register Rate The peak SIP registration arrival rate since the current interval started.
Max Active Calls

The current high water mark of the total number of active calls in both inbound and outbound directions on all trunk groups in the system for specified interval. This statistic applies to calls which are setting up, tearing down or stable.

Switch-over scenario:

When a switch-over occurs from SBC-A to SBC-B, the number of stable calls that were transferred from SBC-A to SBC-B equals the initial value of "maxActiveCalls" (immediately after the switch-over). Subsequent values are calculated and recorded accordingly.

SIP Subscriptions Arrivals The number of SIP SUBSCRIBEs that arrived since the current interval started.
SIP Subscriptions RejectsThe number of SIP SUBSCRIBEs that are rejected due to system congestion since the current interval started.
Avg Subscriptions Rate The average SIP SUBSCRIBE arrival rate calculated using the formula: (# SUBSCRIBE attempts in an interval) / (# seconds elapsed in that interval).
Peak Subscriptions Rate The peak SIP SUBSCRIBE arrival rate since the current interval started.
