SNMP Reporting of Message Data Counters
The message data counter statistics feature enables the system to provide message rate statistics for Call Duration, Call Termination and SIP Methods output. These statistics can be retrieved via SNMP.
Call Duration Counters for SNMP Retrieval
Call duration counters are available by way of SNMP retrieval. These counters are the same as that reported by the show sipd agents and show sipd realms commands. The pertinent MIB objects are found in the ap-sip.mib file.
The applicable Call Duration counters and tables include:
- apSipSACallInfoStatusTable,
which contains:
- apSipSAStatsTotalCallDurationInbound
- apSipSAStatsTotalCallDurationOutbound
- apSigRealmCallInfoStatusTable, which
contains:
- apSigRealmStatsTotalCallDurationInbound
- apSigRealmStatsTotalCallDurationOutbound
Local and Remote Call Termination (BYE) Counters for SNMP Retrieval
Local and Remote Call Termination (BYE) counters are available by way of SNMP retrieval. These counters are the same as that reported by the show sipd agents and show sipd realms commands. The pertinent MIB objects are found in the ap-sip.mib file.
- apSipSaCallInfoStatusTable,
including the Call Termination (BYE) counters:
- apSipSAStatsTotalCallDropsNormal
- apSipSAStatsTotalCallDropsLocal
- apSigRealmCallInfoStatusTable,
including the Call Duration counters:
- apSigRealmStatsTotalCallDropsNormal
- apSigRealmStatsTotalCallLocal
SIP Method Counters for SNMP Retrieval
Global SIP method counters are available by way of SNMP retrieval. These SIP Method counters are the same as that reported by the show sipd <method> command. The pertinent MIB objects are found in the ap-sip.mib file.
The apSipMethodStatsTable holds counters:
- apSipMethodStatsEventCount for each SIP method.
- apSipMethodStatsIndex, whether that SIP method is from server- or client- transaction perspective.
- apSipMethodStatsTransType, and the returned SIP response code.
- apSipMethodStatsEventCode associated with that method transaction and perspective.
SRVCC Objects for SNMP Retrieval
SRVCC counters are available from the
apSipSRVCCStatsobjects. The OID prefix is
1.3.6.1.4.1.9148.3.15.1.1.3
which is found in the
ap-sip.mib
file. The These counters are the same as
that reported by the
show sipd
srvcc command.
The apSipSRVCCStatsobjects contains numerous SRVCC statistics and corresponds to the show sipd srvcc command and the sip-srvcc HDR group.
Rx Policy Server Objects for SNMP Retrieval
Rx policy server counters are available from the
apDiamRxPolicyServerStatsTable. The OID prefix is
1.3.6.1.4.1.9148.3.13.1.1.2.3
which is found in the
ap-diameter.mib
file.
The apDiamRxPolicyServerStatsTable contains numerous policy server statistics and corresponds to the show policy-server stats command and the ext-Rx-policy-server HDR group.
When system boots, every policy server object is assigned id which persists across subsequent reboots. If policy server objects are deleted, the id does not change. This is similar to how session agent objects have persistent indexing.
IKE Session Agent Objects for SNMP Retrieval
IKE Session Agent counters are available from
apSecuritySAIKEStats. The OID prefix is
1.3.6.1.4.1.9148.3.9.5.1
which is found in the
ap-security.mib
file.
The apSecuritySAIKEStats contains numerous session agent statistics concerning IKE traffic and corresponds to the show sa stats ike command and sa-ike HDR group.
IMS-AKA Session Agent Objects for SNMP Retrieval
IMS-AKA session agent counters are available from apSecuritySAIMSAKAStats. The OID prefix is 1.3.6.1.4.1.9148.3.9.5.2 which is found in the ap-security.mib file.
The apSecuritySAIMSAKAStats contains numerous IMS-AKA session agent statistics and corresponds to the show sa stats ims-aka all command and sa-imsaka HDR group.
SRTP Session Agent Objects for SNMP Retrieval
SRTP Session Agent counters are available from
apSecuritySASRTPStats. The OID prefix is
1.3.6.1.4.1.9148.3.9.5.3
which is found in the
ap-security.mib
file.
The apSecuritySASRTPStats contains numerous session agent statistics concerning SRTP traffic and corresponds to the show sa stats srtp command and sa-srtp HDR group.
Transcoding Load Objects for SNMP Retrieval
Transcoding load and resource utilization counters are available in the ap-codec.mib file. There are three groups which are presented, currently active transcoded session per licensed codec, maximum licensed capacity per licensed codec, load per DSP.
Active Transcoded Sessions
The apCodecTranscodingResourceUtilMIBObjects, OID:
1.3.6.1.4.1.9148.3.7.2.5 presents the current number of active sessions of
licensed codecs. This is found in
ap-codec.mib
.
This object corresponds to show xcode load ACLI Command and xcode-codec-util HDR group.
DSP Load of Transcoding Module
ap-codec.mib
:
- TCU identifier
- TCM Identifier
- DSP Identifier
- Session Count for that DSP
- Current load for that DSP
- Peak load for that DSP
- DSP Overload state
Note:
If the DSP is neither Active nor Overloaded then that DSP will not appear as an instance of the table.This object corresponds to show xcode load -detail ACLI Command and xcode-tcm-util HDR group.
Licensed Codec Capacity
MIB Objects that present maximum capacity of licensed codecs are found
in
ap-license.mib
, as part of the apLicenseEntry,
OID:1.3.6.1.4.1.9148.3.5.1.1.1
This object corresponds to show xcode load ACLI Command and xcode-codec-util HDR group.
