[jboss-jira] [JBoss JIRA] Assigned: (JBAS-4227) [SnmpAgentService] MIB2SystemGroup violates RFC-1213

[SnmpAgentService] MIB2SystemGroup violates RFC-1213 ---------------------------------------------------- Key: JBAS-4227 URL: http://jira.jboss.com/jira/browse/JBAS-4227 Project: JBoss Application Server Issue Type: Bug Security Level: Public(Everyone can see) Components: JMX Affects Versions: JBossAS-4.0.4.GA Reporter: Kenny MacLeod Assigned To: Tobias Frech The SnmpAgentService exposes a standard MIB2 System Group. However, the OIDs that are produced violate RFC-1213, which dictates that the sysUpTime value should have a type of TimeTicks. Instead, SnmpAgentService generates a type of int32. Take the following output from snmpwalk: SNMPv2-MIB::sysDescr = STRING: Central Computer SNMPv2-MIB::sysObjectID = OID: SNMPv2-SMI::enterprises.18016.1.1.2 SNMPv2-MIB::sysUpTime = Wrong Type (should be Timeticks): Gauge32: 769331 SNMPv2-MIB::sysContact = STRING: Agent Smith SNMPv2-MIB::sysName = STRING: kizoom(a)10.10.0.208 SNMPv2-MIB::sysLocation = STRING: In The Matrix SNMPv2-MIB::sysServices = INTEGER: 64 End of MIB For systems which monitor SNMP agents (e.g. OpenNMS), this causes them to reject the agent because of the bad type. The bug lies in org.jboss.jmx.adaptor.snmp.agent.RequestHandlerImpl, which determines the type of the OID value by examining the type of the JMX attribute being monitored. It has no way to generate a TimeTicks value, it can only handle Long, String, Integer and SnmpOID types. The JBoss wiki states that RFC-1213 is supported, but this is incorrect when the type for sysUpTime is wrong (http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossSNMPAdapterGetValues). Also the attributes.xml file in xnmp-adaptor.sar quotes RFC-1213.
