CHAPTER 6 Performance Monitoring
Mediant 800 SBC | SNMP Reference Guide
The SNMP trap event acPerformanceMonitoringThresholdCrossing is sent every time the
high or low threshold of a Performance Monitored MIB object is crossed (see
Monitoring Threshold-Crossing Trap
on page 162). The severity field is 'indeterminate'
when the crossing is above the threshold and 'cleared' when it returns to below the
threshold. The trap's 'source varbind' indicates the object for which the threshold is
crossed. To enable this feature, load an ini file to the device with the following parameter
setting:
PM_EnableThresholdAlarms = 1
Once enabled, you can change the low and high threshold values from their default
values, through ini file by using the following syntax:
PM_<MIB Source Name> = '1,<Low Threshold>,<High Threshold>,15'
where:
●
<MIB Source Name>:
The source name of the MIB (e.g., PM_TrunkUtilization, PM_
NetUtilKBytes, and PM_gwIPGroupOutINVITEDialogs)
●
<Low Threshold>:
Defines the low-threshold value
●
<High Threshold>:
Defines the high-threshold value
The value "15" in the syntax is the measuring interval, which is always fixed at 15 minutes.
The following is an example of an ini file that configures the acPMSIPIPGroupOutIn-
viteDialogsTable performance monitoring MIB (OID 1.3.6.1.4.1.5003.10.8.2.52.35) with a
low threshold of 10 and a high threshold of 18:
