snmpwalk works but snmp items fail to populate

[cirrhus9.com]

We are running Zabbix 1.8.10 (revision 24303)
on a CentOS 5.9 host with updated (today) snmp utils
(net-snmp-5.3.2.2-22.el5_10.1)

snmpwalk -v 2c -c <string> <ip>

works via c-line, but our snmp-templated items do not.

The Template_SNMPv2_Device template is not linked as I only copied 3 items over, these did not and do not show up under Latest Data.
The target host is WIN08SR2 - Standard

I then linked the Template_SNMPv2_Device to the host and waited.
Some items became not supported

All snmp items are SNMPv2 agent and the correct community_string is being used.

I set debug=4 in zabbix_server.conf and bounced, the log file shows:

  2238:20140416:055037.549 SNMP item [icmpOutErrors] on host [cwWindows] failed: another network error, wait for 15 seconds
  2228:20140416:055038.051 SNMP item [icmpOutMsgs] on host [cwWindows] failed: another network error, wait for 15 seconds
  2227:20140416:055039.824 SNMP item [icmpOutParmProbs] on host [cwWindows] failed: another network error, wait for 15 seconds
  2239:20140416:055040.973 SNMP item [icmpOutRedirects] on host [cwWindows] failed: another network error, wait for 15 seconds

and

tcpdump -l -vvv -x -X port 161 -i eth0 and dst <ip> -c 5

while snmpwalk'ing shows:

06:00:38.988337 IP (tos 0x0, ttl  64, id 0, offset 0, flags [DF], proto: UDP (17), length: 76) monitoring.cirrhus9.com.39410 > dev.domain.com.snmp: [COLOR=red][COLOR=black][[/COLOR]bad udp cksum[/COLOR] 1fb!]  { SNMPv2c C=<community_string> { GetNextRequest(25) R=1462806426   }

NOTE: "dev.'domain.com'.snmp" here is NOT the hosts name. This remains a mystery to me.

and now, I'm off to try and use zabbix_sender to collect the metrics I need.

Is there an "updated" Template_SNMPv2_Device somewhere, this one may be corrupt? I got this one here some time ago but I can't find the source link any more.

Thank you.

I removed most everything snmp-related and just used the agent items from the Linux Template but the host is only collecting 5 items.
snapshot of those items. (they do update)

I stuck these in the agentd.conf and bounced:

UserParameter=disk.used, df  /dev/xvda | tail -1 | awk '{print $3}' 
UserParameter=disk.free, df  /dev/xvda | tail -1 | awk '{print $4}'
UserParameter=1m.load.avg, uptime | awk -F 'load average:' '{ print $2 }' | awk '{print $1}' | sed 's/,//g'
UserParameter=5m.load.avg, uptime | awk -F 'load average:' '{ print $2 }' | awk '{print $2}' | sed 's/,//g'
UserParameter=15m.load.avg, uptime | awk -F 'load average:' '{ print $2 }' | awk '{print $3}' | sed 's/,//g'

When nothing showed up, I updated them to Active and this is in the log
(running DebugLevel=4)

Well, I still have NO data under Latest Data for snmp items, but we do have graphs and that's enough for this task.

Excuse me if I'm wrong - What kind of host would you like to monitor by SNMP?

In first part of your post you was talking about

The target host is WIN08SR2 - Standard

Then, when you update you post, your target host was changed:

just used the agent items from the Linux Template

Please, draw the full picture:
- zabbix server - OS?
- zabbix agent - OS? Is SNMP daemon enabled? What is the result of

#snmpwalk -v 2c -c public {ip_of_client} 1.3.6.1.2.1.1

Sorry about that - but some servers doesn't have SNMP enabled by default. You have to turn it on and do some additional configuration. The same story about network devices - some of them works with SNMP by default, some of them - not.

Aleksey:

The issue presently is with WindowsServer 2008 R2 standard and enterprise editions.
SNMP Service with correct Security and Community settings haven't changed and snmpwalk and snmpget on any Windows host currently having this issue all return values from the queries.

Graphs for snmp data show recent values, it's just that "Latest Data" does not show any values for those same elements.
Currently, this is affecting ALL snmp elements for all of our hosts that use snmp v2c items.

We expect to double the available RAM on this instance this week as I'm hoping this is a performance-related issue.

Thank you.

OK, I see what you meant.

Try to use "Filter" option - it's almost invisible word on blue line between dropdown selection fields "Group" and "Host" - and Data table.

Select one group, one host and filter only "escr" to check if you have any Description got by SNMP.

To check all data from all hosts in group - try to use "Overview"

Aleksey:

Thank you!
That damned filter had something in it and was collapsed. This accounts for why I saw "no data" for snmp-related items.

You rock!

[aib]

Anytime!

I have a 'tip' or a Feature request along these lines...
a popup or bubble tip/ balloon that indicates "You have a filter set" anywhere there is one.

Thanks. Now I can get off 1.8.10 and get "current" soon...

1.8 > 2.0 > 2.2 is what heaje on irc told me.

Now I can sleep tonight!
