Available as of Camel 2.1
The snmp: component gives you the ability to poll SNMP capable devices or receiving traps.
Maven users will need to add the following dependency to their pom.xml
for this component:
<dependency> <groupId>org.apache.camel</groupId> <artifactId>camel-snmp</artifactId> <version>x.x.x</version> <!-- use the same version as your Camel core version --> </dependency> |
snmp://hostname[:port][?Options] |
The component supports polling OID values from an SNMP enabled device and receiving traps.
You can append query options to the URI in the following format, ?option=value&option=value&...
|
Given the situation, that I poll for the following OIDs:
1.3.6.1.2.1.1.3.0 1.3.6.1.2.1.25.3.2.1.5.1 1.3.6.1.2.1.25.3.5.1.1.1 1.3.6.1.2.1.43.5.1.1.11.1 |
The result will be the following:
<?xml version="1.0" encoding="UTF-8"?> <snmp> <entry> <oid>1.3.6.1.2.1.1.3.0</oid> <value>6 days, 21:14:28.00</value> </entry> <entry> <oid>1.3.6.1.2.1.25.3.2.1.5.1</oid> <value>2</value> </entry> <entry> <oid>1.3.6.1.2.1.25.3.5.1.1.1</oid> <value>3</value> </entry> <entry> <oid>1.3.6.1.2.1.43.5.1.1.11.1</oid> <value>6</value> </entry> <entry> <oid>1.3.6.1.2.1.1.1.0</oid> <value>My Very Special Printer Of Brand Unknown</value> </entry> </snmp> |
As you maybe recognized there is one more result than requested....1.3.6.1.2.1.1.1.0.
This one is filled in by the device automatically in this special case. So it may absolutely happen, that you receive more than you requested...be prepared.
Polling a remote device:
snmp:192.168.178.23:161?protocol=udp&type=POLL&oids=1.3.6.1.2.1.1.5.0 |
Setting up a trap receiver (Note that no OID info is needed here!):
snmp:127.0.0.1:162?protocol=udp&type=TRAP |
From Camel 2.10.0, you can get the community of SNMP TRAP with message header 'securityName',
peer address of the SNMP TRAP with message header 'peerAddress'.
Routing example in Java: (converts the SNMP PDU to XML String)
from("snmp:192.168.178.23:161?protocol=udp&type=POLL&oids=1.3.6.1.2.1.1.5.0"). convertBodyTo(String.class). to("activemq:snmp.states"); |
