Host down...but not down?

[hipsterdoofus]

But does your device answer to one of both OIDs? Your example shows a private MIB OID
Reinhard

Answers either...this is what I get:

[cactiuser@xhost ~]$ snmpwalk -c public -v 1 10.59.33.175 .1.3.6.1.2.1.1.1.0
SNMPv2-MIB::sysDescr.0 = STRING: Galaxy 3000 20 kVA
[cactiuser@xhost ~]$ snmpwalk -c public -v 1 10.59.33.175 .1.3.6.1.2.1.1.3.0
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (718652611) 83 days, 4:15:26.11

I get response from these OID's too

[cactiuser@suicacti cacti]# snmpwalk -v1 -c public 128.243.44.70 .1.3.6.1.2.1.1.1.0
SNMPv2-MIB::sysDescr.0 = STRING: ConnectUPS Web/SNMP Card V4.28
[cactiuser@suicacti cacti]# snmpwalk -v1 -c public 128.243.44.70 .1.3.6.1.2.1.1.3.0
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (749715498) 86 days, 18:32:34.98

And this is the particulars on the server in question...

Cacti Version 0.8.7a
Cacti OS unix
SNMP Version net-snmp
RRDTool Version RRDTool 1.2.x

Finally I found others with the same issues... =)

I'm monitoring several routers, switches and UPS devices. I upgraded from 0.8.6->0.8.7b and suddenly I got NaN in the graphs for the PowerWare 9305 UPS devices. I was working fine before the version upgrade. All other graphs are working just fine.

When turning on debugging to cacti.log, I see the following regarding the UPS:

12/11/2008 09:30:09 PM - SPINE: Poller[0] Host[167] SNMP Result: Host did not respond to SNMP

But it sure does if I look under device management:

UPS EDC1 40kW (ups40kw)
SNMP Information
System: ConnectUPS Web/SNMP Card V3.03
Uptime: 1757616298 (203 days, 10 hours, 16 minutes)
Hostname: ConnectUPS Web/SNMP Card
Location:
Contact:

I will look forward to a solution on this weird issue.

Thank goodness there are others with same issue...all my other devices are fine...just this UPS has this problem.

[gandalf]

This is always a SNMP V1 device or a V2c? In the latter case, snmpbulkwalk may introduce problems.
A solution would be to use a network sniffer (aka wireshark) to capture both cacti and your cli snmpwalk to find any difference
Reinhard

[mgades]

The UPS management card only talks SNMP v1.

[gandalf]

Sorry, no clue, then. Personally, I'd start a wireshark trace then to see what's going on
