Mediant 1000 Gateway & E-SBC | User's Manual
Parameter Description
Note: The calculation depends on the configured minimum samples
(see 'Minimum Samples' parameter). For example, if the parameter is
configured to five minutes, but the number of calls during the interval
is less than the configured minimum samples, no calculation is done.
Configuring User-Defined Performance Monitoring
MIBs
The User Defined Failure PM table lets you configure up to 26 user-defined Performance Monitoring
(PM) SNMP MIB rules for SBC calls. Each rule represents a group of MIBs that counts the number
of specified SIP failure responses (e.g., SIP 403 and 504) and/or specified responses generated
internally by the device (e.g., CAC limit reached or NER threshold crossed). You can configure the
PMs to count responses due to sent SIP INVITE or REGISTER messages. In other words, these
PMs only count calls that fail before they can be established.
Each user-defined PM group includes the following PM MIBs:
■ acPMSBCInUserDefinedFailures<1-26>Table: Counts the total number of incoming
responses
■ acPMSBCOutUserDefinedFailures<1-26>Table: Counts the total number of outgoing
responses
■ Per SRD:
● acPMSBCSRDInUserDefinedFailures<1-26>Table: Counts the total number of incoming
responses per SRD
● acPMSBCSRDOutUserDefinedFailures<1-26>Table: Counts the total number of outgoing
responses per SRD
■ Per IP Group:
● acPMSBCIPGroupInUserDefinedFailures<1-26>Table: Counts the total number of
incoming responses per IP Group
● acPMSBCIPGroupOutUserDefinedFailures<1-26>Table: Counts the total number of
outgoing responses per IP Group
● This feature is applicable only to the SBC application.
● The PMs only count original responses and not responses that you may have
manipulated using Message Manipulation rules. For example, if you have
configured a user-defined PM to count SIP 408 responses and you have a Message
Manipulation rule that changes SIP 403 responses into SIP 408, the PM will not
include these manipulated responses in its' count.
● The PMs consider incoming SIP CANCEL messages as SIP 487 responses.
● The PMs don't count SIP BYE requests.
The following procedure describes how to configure user-defined PM rules through the Web
interface. You can also configure it through ini file [UserDefinedFailurePM].
➢ To configure user-defined PMs:
1. Open the User Defined Failure PM table (Monitor menu > Monitor tab > Performance
Monitoring folder > User Defined Failure PM).
2. Click New; the following dialog box appears:
