Dmytro Vitiuk created AMBARI-25609: -------------------------------------- Summary: sysUpTime field is populated with invalid value during SNMP trap creation Key: AMBARI-25609 URL: https://issues.apache.org/jira/browse/AMBARI-25609 Project: Ambari Issue Type: Bug Components: ambari-server Affects Versions: 2.7.5 Reporter: Dmytro Vitiuk Fix For: 2.7.6
Ambari tries to set milliseconds to the "sysUpTime" field: [https://github.com/apache/ambari/blob/8e35277c24cc0ffd897c1dc727b2cc528cb8148b/ambari-server/src/main/java/org/apache/ambari/server/notifications/dispatchers/AmbariSNMPDispatcher.java#L120] but this field accepts hundreds of milliseconds: {noformat} The time (in hundredths of a second) since the network management portion of the system was last re-initialized. {noformat} ([https://tools.ietf.org/html/rfc1907#section-2.1]) So after about 50-days in up-time an ambari server is not able to populate "sysUpTime" with a correct value (the max value the field is able to accept is "4294967295" - it is about 50 days in milliseconds). Exception in ambari-server.log: {noformat} java.lang.IllegalArgumentException: Argument must be an unsigned 32bit value at org.snmp4j.smi.UnsignedInteger32.setValue(UnsignedInteger32.java:144) at org.snmp4j.smi.UnsignedInteger32.<init>(UnsignedInteger32.java:53) at org.snmp4j.smi.TimeTicks.<init>(TimeTicks.java:58) at org.apache.ambari.server.notifications.dispatchers.AmbariSNMPDispatcher.prepareTrap(AmbariSNMPDispatcher.java:120) at org.apache.ambari.server.notifications.dispatchers.SNMPDispatcher.sendTraps(SNMPDispatcher.java:244) at org.apache.ambari.server.notifications.dispatchers.SNMPDispatcher.dispatch(SNMPDispatcher.java:157) at org.apache.ambari.server.notifications.DispatchRunnable.run(DispatchRunnable.java:58) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) {noformat} -- This message was sent by Atlassian Jira (v8.3.4#803005)
