Hello,
How many devices are monitored?
Generally this kind of behavior observed in our network monitoring tool,
because of devices are having same engine ID.
Please check once whether two devices in network are having same engine ID?
Thanks,
Sudheer.

Subject: Agent Reporting usmStatsNotInTimeWindows
Hi,
We are using net-snmp5.2.6 library to communicate with switches SNMP agent.
Our manager was working fine for some time without any issues. after some days
the agent starts giving report " usmStatsNotInTimeWindows" to all GETNEXT
queries. we noticed that the enginetime supplied by manager and enginetime
respond by agent is having a huge difference.
Manager : keep on sending Encrypted PDU snmp v3 communication with parameters (
snmp.msgID: 6828301
snmp.msgAuthoritativeEngineID:8000000903000DEC246A00
snmp.msgAuthoritativeEngineBoots:6
snmp.msgAuthoritativeEngineTime:17501513
Agent:
Encrypted PDU is replied by the switch's SNMP agent with the parameters
snmp.msgID: 6828301
snmp.msgAuthoritativeEngineID:8000000903000DEC246A00
snmp.msgAuthoritativeEngineBoots:6
snmp.msgAuthoritativeEngineTime:2935400
When we contact with Agent team , they say that It is a problem from manager
that it is not using the enginetime provided by agent. when I look deep in code
I see that we use " snmp_sess_synch_response" function of net-snmp and net-snmp
lib generates this engineboot, enginetime values.
We restart the manger and it solves the problem.
Let me know how engine time is calculated in net-snmp?, What action net-snmp
does if there is a "usmStatsNotInTimeWindows" repor generted by agent?.
Your Help is highly appreciated..
Thanks,
Naj..
