SNMP - Private MIBs

 

 

With the addition of Feature F-5887 Adding SNMP Private MIBs, the IMG 2020 now supports SNMP Private MIBs that include monitoring the CPU, Memory, Temperature, and Call Statistics.

The Private MIBs are included in a .zip file labeled bdn2020_ver230xxx_mib.zip (xxx=build number) that is provided with the IMG software downloads.

Once downloaded, the Private MIBs need to be loaded into the directory of the SNMP Manager where the MIB files are to be stored and then compiled. Below is a screen capture of the directory structure of the Dialogic Private MIB file after the file has been loaded and compiled. As displayed below, a dialogic directory is created under the private directory. Under the dialogic directory is the bdn2020 product and then all the statistics that can be monitored.

Private MIB OID Tree Mapping

The Diagram below displays the Private MIB branch currently supported on the IMG 2020.

 

 

Below is a table displaying the Private MIBs that were added to monitor various statistics. Each individual statistic such as temperature or channel group statistics are further broken down to individual functions. The main categories are as follows:

Function

OID

CPU Info Statistics

1.3.6.1.4.1.3028.6.1.7.1.1

Memory Pool Statistics

1.3.6.1.4.1.3028.6.1.7.1.2

Temperature Statistics

1.3.6.1.4.1.3028.6.1.7.1.3

Channel Group Statistics

1.3.6.1.4.1.3028.6.1.7.1.4

Active Alarms

1.3.6.1.4.1.3028.6.1.7.2

 

The SNMP statistics need to be queried by the SNMP Manager in order to retrieve each of the statistics displayed in the table above. The Active Alarms information however is automatically transmitted from the IMG 2020 to the SNMP Manager in an SNMP Trap each time an alarm is generated.

Statistics

The tables below break down each of the statistics, displays the OID of each, and gives a brief description.

*  The Query Interval configured in the SNMP Manager should be configured to equal the 300 seconds default refresh rate configured in the  SNMP Agent  object on the IMG 2020 .

This tree contains 60 values for each SNMP Entry Element.
This consists of 12 historic values for each of the 5 signalling types the IMG supports (SS7, H.323, SIP, ISDN, CAS). 12 x 5 = 60.

Therefore for
1.3.6.1.4.1.3028.6.1.7.1.4.1.1.element.x

x = 1 - SS7 current value

x = 2 - H323 current value

x = 3 - SIP current value

x = 4 - ISDN current value

x = 5 - CAS current value

then

x = 6 - SS7 value 5 minutes ago

x = 7 - H323 value 5 minutes ago

x = 8 - SIP value 5 minutes ago

x = 9 - ISDN value 5 minutes ago

x = 10 - CAS value 5 minutes ago

and so on.
