Receiving Custom Key Value Events via SNMP

Purpose:

This application demonstrates how to configure ESB Streaming Integrator Tooling to receive snmp source 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, port, user access.
  3. If there is no syntax error, the following message is shown on the console:
      • SNMP-get-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!

Viewing the Results:

See the output. Following message would be shown on the console. 

INFO {io.siddhi.core.stream.output.sink.LogSink} - SNMP-get-request-app : logStream : Event{timestamp=1************, data=[1:28:33.05, mail@wso2.com], isExpired=false}
INFO {io.siddhi.core.stream.output.sink.LogSink} - SNMP-get-request-app : logStream : Event{timestamp=1************, data=[1:28:38.05, mail@wso2.com], isExpired=false}
