Sending Custom Keyvalue Events via SNMP

Purpose:

This application demonstrates how to configure WSO2 Streaming Integrator Tooling to send snmp set request via SNMP in keyvalue using custom mapping.

Prerequisites:

  1. Save this sample.
  2. Install snmp agent on your network node.
    • for linux can install snmpd / for windows it can be configured by 'windows features'.
    • configure snmp agent ex:- community string = public,
  3. If there is no syntax error, the following message is shown on the console:
      • SNMP-set-request-app successfully deployed.

Executing the Sample:

  1. Start the Siddhi application by clicking on 'Run'.
  2. If the Siddhi application starts successfully, the following messages are shown on the console:
    • SNMP-set-request-app - Started Successfully!

Testing the Sample:

  1. Click on 'Event Simulator' (double arrows on left tab)
  2. Click 'Single Simulation' (this will be already selected)
  3. Select SNMP-set-request-app as 'Siddhi App Name'
  4. Select outputStream as 'StreamName'
  5. Provide attribute values
    • sysLocation : asia-branch-singapore
  6. Click on the start button (Arrow symbol) next to the newly created simulator

Viewing the Results:

See the output on the terminal: INFO {io.siddhi.core.stream.output.sink.LogSink} - SNMP-set-request-app : logStream : Event{timestamp=1*********, data=[asia-branch-singapore], isExpired=false}

Notes:

Make sure the port number is correct and user have write access to agent
