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:¶
- Save this sample.
- 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,
- If there is no syntax error, the following message is shown on the console:
-
- SNMP-set-request-app successfully deployed.
-
Executing the Sample:¶
- Start the Siddhi application by clicking on 'Run'.
- If the Siddhi application starts successfully, the following messages are shown on the console:
- SNMP-set-request-app - Started Successfully!
Testing the Sample:¶
- Click on 'Event Simulator' (double arrows on left tab)
- Click 'Single Simulation' (this will be already selected)
- Select SNMP-set-request-app as 'Siddhi App Name'
- Select outputStream as 'StreamName'
- Provide attribute values
- sysLocation : asia-branch-singapore
- 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
