> camel-snmp component does correctly read SNMPv1 type PDUs from snmp4j
> ---------------------------------------------------------------------
>
> Key: CAMEL-5251
> URL: https://issues.apache.org/jira/browse/CAMEL-5251
> Project: Camel
> Issue Type: Bug
> Components: camel-snmp
> Affects Versions: 2.9.2
> Reporter: Ed Manero
> Attachments: SnmpConverters.java
>
>
> SnmpConverters.java of the camel-snmp component inspects the PDU using
> getVariableBindings(). This method does not contain any information for PDUs
> representing SNMPv1 messages. The javadoc for org.snmp4j.PDUv1 indicates that
> unique accessors are provided for PDU instances of this type. Because of
> this SnmpConverters.java needs to check if the PDU provided by snmp4j
> represents an SNMPv1 message and if so use the special accessors to construct
> the message.
> Here is a test case as posted from the user forum. Note that for SNMPv1 type
> messages the body is empty (Body:<snmp></snmp>).
> I'm starting to create some simple use cases with Camel and SNMP
> traps, and I'm running into some issues (this might just be because I
> don't understand properly what's going on). My current problem is that
> when I create a route for SNMP traps and send SNMP v1 traps to it,
> Camel seems to lose information from the trap such as the originating
> IP address of the trap.
> Here's what I'm doing: I first generate my camel project with the maven
> command:
> mvn archetype:generate -DarchetypeGroupId=org.apache.camel.archetypes
> -DarchetypeArtifactId=camel-archetype-spring -DarchetypeVersion=2.9.2
> -DgroupId=camel-snmp-test -DartifactId=camel-snmp-test
> And modify the camel-context.xml file to contain the route:
> <camel:route>
> <camel:from uri="snmp://0.0.0.0:1162?type=TRAP"/>
> <camel:to uri="log://foo?showAll=true"/>
> </camel:route>
> then run the project with:
> mvn camel:run
> I then generate a trap with the net-snmp command snmptrap and the syntax:
> snmptrap -v 1 -c public 127.0.0.1:1162
> SNMPv2-MIB::authenticationFailure 1.2.3.4 0 coldStart.0 10
> This gives me a log message of:
> [PTransportMapping_0.0.0.0/1162] foo INFO
> Exchange[Id:ID-addict-33083-1335950429878-0-18,
> ExchangePattern:InOnly,
> Properties:{CamelToEndpoint=log://foo?showAll=true,
> CamelCreatedTimestamp=Wed May 02 10:28:25 WEST 2012},
> Headers:{breadcrumbId=ID-addict--33083-1335950429878-0-17},
> BodyType:String, Body:<snmp></snmp>, Out: null]
> I'd expect to see the enterprise-oid
> (SNMPv2-MIB::authenticationFailure), agent (1.2.3.4), trap-type (0),
> specific-type (coldStart.0), and uptime (10 seconds), it would be nice
> to see the IP that the PDU came from as well because not all traps
> include a useful agent address.
> Interestingly, with SNMP v2 traps I get some of this information in
> the body (although no sender IP address):
> snmptrap -v 2c -c public localhost:1162 ''
> SNMPv2-MIB::authenticationFailure SNMPv2-MIB::sysLocation.0 s "just
> here"
> [PTransportMapping_0.0.0.0/1162] foo INFO
> Exchange[Id:ID-addict-33083-1335950429878-0-20,
> ExchangePattern:InOnly,
> Properties:{CamelToEndpoint=log://foo?showAll=true,
> CamelCreatedTimestamp=Wed May 02 11:33:49 WEST 2012},
> Headers:{breadcrumbId=ID-addict-33083-1335950429878-0-19},
> BodyType:String,
> Body:<snmp><entry><oid>1.3.6.1.2.1.1.3.0</oid><value>11 days,
> 23:15:58.58</value></entry><entry><oid>1.3.6.1.6.3.1.1.4.1.0</oid><value>1.3.6.1.6.3.1.1.5.5</value></entry><entry><oid>1.3.6.1.2.1.1.6.0</oid><value>just
