SNMP - Private MIBs

With the addition of Feature F-5887 Adding SNMP Private MIBs, the 2020 IMG 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_ver220xxx_mib.zip (xxx=build number) that is loaded on Dialogic BBS (Bulletin Board System). See below.

Obtain MIB file from Dialogic BBS (Bulletin Board System)
  • Go to http://www.dialogic.com/support. Click on the Manuals and Downloads tab.
  • Click on the Download Product Software link.
  • Select 2020 IMG from drop down menu. On the page that appears, click on Support Page (login required) link.
  • For login information, refer to the welcome letter e-mailed after purchase of product or contact Dialogic Sales and Support for information on getting a logon username and password.
  • Download the latest 2020 IMG file labeled bdn2020_ver220xxx_mib.zip (xxx=build number) which will include the Private MIBs.


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 2020 IMG.

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

1.3.6.1.4.1.3028.6.1.1

Memory Pool Statistics

1.3.6.1.4.1.3028.6.1.2
Temperature Statistics 1.3.6.1.4.1.3028.6.1.3
Channel Group Statistics 1.3.6.1.4.1.3028.6.1.4

Active Alarms

1.3.6.1.4.1.3028.6.2

 

Note: 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 2020 IMG 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 2020 IMG.
