Zixi Broadcaster enables monitoring and control via SNMP (on Linux only). The monitoring system can receive SNMP Trap messages from Zixi Broadcaster as well as access monitored objects with read-only and read-write access privileges (objects and their access permissions are defined in the MIB). Zixi Broadcaster supports SNMPv1, SNMPv2, and SNMPv3. Before using SNMP you need to ensure that SNMP is enabled in your Zixi Broadcaster license, run a script, as described below, and configure the SNMP settings in the Settings >SNMP screen. 

Activating SNMP

To Activate SNMP:

• Run the script file ./install_snmp.sh, located in the Broadcaster folder, where Zixi Broadcaster was installed. The events on the log screen are deleted.

Configuring SNMP Settings

 To Configure SNMP:

1. In Zixi Broadcaster UI, go to Settings > SNMP.

To Refresh the Screen:

...

1. 1. • enter the SNMP user name.
      • In the Write Access field, select the checkbox to allow Read-Write access rights. If the checkbox is not selected, the user will have Read-only access rights.
      • In the Password field, enter the SNMP user's password.
2. Under the Trap Receivers section, specify SNMP Trap receivers that will listen to the SNMP Traps that will be sent by Zixi Broadcaster, by clicking the + button to add a trap receiver. 
   The following screen appears:

3. In the Community field, specify the community name for access.
4. In the Host field, specify the IP address to which the Trap messages will be transmitted.
5. In the Port field, specify the Port number to which the Trap messages will be sent transmitted.
6. Click Apply.

Viewing MIB Information

You can view the "Root MIB" (which defines the Zixi Broadcaster tree root definitions) and the "Broadcaster MIB" (which describes the Zixi Broadcaster MIB tree definition, including all its objects). 

To view MIB information:

1. In Zixi Broadcaster UI, go to Settings > SNMP.
2. At the upper right-hand corner click the Root MIB and/or Broadcaster MIB links.

SNMP Alerts/Notifications

The SNMP traps are sent when an alert is raised and when alert is cleared on following occasions:

• Input stream alerts ( zbtInputStreamAlertRaised = .1.3.6.1.4.1.38369.1.1.1.0.58;  zbtInputStreamAlertCleared =  .1.3.6.1.4.1.38369.1.1.1.0.60)
  Important parameters:  
  $ zbsProgramID ( Id of the broadcaster that sends the trap,  .1.3.6.1.4.1.38369.1.1.1.1.2)
