SNMP Monitoring¶

Simple Network Management Protocol (SNMP) is an Internet-standard protocol for managing devices on IP networks. Given below is how to configure SNMP in WSO2 Micro Integrator, which exposes various MBeans via SNMP.

Enabling SNMP¶

Download the following jar files from http://www.snmp4j.org and add them to the MI_HOME/lib directory.
- snmp4j-2.1.0.jar
- snmp4j-agent-2.0.6.jar
Enable SNMP in the ei.toml file, stored in the MI_HOME/conf/ file by adding the following entry:
```
[synapse_properties]
'synapse.snmp.enabled'=true
```

WSO2 Micro Integrator can now monitor MBeans with SNMP. For example:

Monitoring Info : OID branch "1.3.6.1.4.1.18060.14" with the following sub-branches:

1 - ServerManager MBean
2 - Transport MBeans
3 - NHttpConnections MBeans
4 - NHTTPLatency MBeans
5 - NHTTPS2SLatency MBeans

MBean OID mappings¶

Following are the OID equivalents of the server manager and transport MBeans, which are described in JMX Monitoring:
