verbose query failing, but snmpwalk succeeds

[edward1234]

Hi,

I've been using some custom scripts that aggregate iostat output of devices that make up Veritas Volumes. The custom scripts write to a file, which is read by a script written by Mark Round. Everything was working fine for over a year. Recently, I added some devices/volumes to my clients and attempted to create graphs for them via the "Devices" page and "Create Graphs for this Host". The new volumes didn't show up, which lead me to run "Verbose Query", which gives me...

+ Running data query [26].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/mnt/data/cacti/cacti/resource/snmp_queries/solaris/solaris-iostat.xml'
+ XML file parsed ok.
+ Executing SNMP walk for list of indexes @ '.1.3.6.1.3.1'
+ No SNMP data returned
+ Found data query XML file at '/mnt/data/cacti/cacti/resource/snmp_queries/solaris/solaris-iostat.xml'

+ Found data query XML file at '/mnt/data/cacti/cacti/resource/snmp_queries/solaris/solaris-iostat.xml'

But snmpwalk on my cacti server works fine. The existing graphs are still collecting/graphing data.

I tried adding new "Devices" (which is actually a host that's arleady being graphed), but that failed. I made a copy of solaris-iostat.xml and created a new Data Query with all new Data and Graph Templates, which also failed.

I compared everything (that I could think of) to a test cacti server, which works fine. One other thing to note is the cacti drive filled and was cleaned up a few weeks ago, prior to me trying to add the new graphs. Turning logging up to Debug doesn't seem to yield any additional information for the Verbose Query failure.

Thanks in advance for your help.

Check your apache error log for some interesting output. However, I'm not quite sure it'll have anything.

Thanks for the quick response. Can you tell me exactly what Verbose Query is doing? ie, the difference between Verbose Query and snmpwalk?

[TheWitness]

Gathering information about all the rows in the data query that have the input direction associated with them. Things like 'ifAlias', 'ifDescription', etc.

Can you give me something lower level and detailed so I can troubleshoot the issue?

Thanks, I'll take a look.

I figured it out...kind of. snmpdx, Solaris' Master Agent wasn't running. Not sure exactly why it didn't allow the "verbose query" to work, when snmpwalk was able to pull down all data, but starting snmpdx seems to have fixed my issue.

Thanks for your help.

I meet a similar issue today.

My lab test device has a OID that walks slow, so I set the timeout to 5 second, and snmpwalk command suceeds.
snmpwalk -c public -v 2c -t 5 10.xx.xx.xx 1.3.6.1.4.1.xxxxxx

But Verbose Query always failing, even set the SNMP Timeout a long time.

Dose the Verbose Query use the snmpwalk.exe, or use the php_snmp.dll?
What shall I do, to make the Verbose Query success?

P.S. I use the Windows OS.

Did you apply the long timeout setting to that host, then? Remember, that 5 secs are written as 5000 ms for cacti.
And you may want to reduce max oid to 1 to prevent snmpbulkwalk to be used
