ucd/net snmp get monitored partitions not working

geefour · Post by **geefour** » Thu Apr 20, 2006 5:16 am

I've got a CentOS 4.2 host monitored for ucd/net CPU Load, Load average and memory usage, which are all working fine. I'm just struggling to get the monitored partitions to work. When i run the verbose query in the setup i get the following.

Code: Select all

+ Running data query [2].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/web/docroot/cacti-0.8.6g/resource/snmp_queries/net-snmp_disk.xml'
+ XML file parsed ok.
+ Executing SNMP walk for list of indexes @ '.1.3.6.1.4.1.2021.9.1.1'
+ No SNMP data returned
+ Found data query XML file at '/web/docroot/cacti-0.8.6g/resource/snmp_queries/net-snmp_disk.xml'
+ Found data query XML file at '/web/docroot/cacti-0.8.6g/resource/snmp_queries/net-snmp_disk.xml'
+ Found data query XML file at '/web/docroot/cacti-0.8.6g/resource/snmp_queries/net-snmp_disk.xml'

Any ideas as to why this isn't being picked up yet the other ucd/net queries are?

Thanks

Hi

add this to /etc/snmp/snmpd.conf :

Code: Select all

includeAllDisks

You have to restart (or kill -1) the SNMP agent.

Hey, thats got me somewhere, now the verbose query gives me this...

Code: Select all

+ Running data query [2].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/web/docroot/cacti-0.8.6g/resource/snmp_queries/net-snmp_disk.xml'

+ Executing SNMP walk for data @ '.1.3.6.1.4.1.2021.9.1.1'
+ Found item [dskIndex='No Such Instance currently exists at this OID'] index: 1 [from value]

+ Executing SNMP walk for data @ '.1.3.6.1.4.1.2021.9.1.2'

+ Found data query XML file at '/web/docroot/cacti-0.8.6g/resource/snmp_queries/net-snmp_disk.xml

I get the message No Such Instance currently exists at this OID when i try to add graphs.
Its a Poweredge 850 btw with SATA, if this makes any difference.

Can you post your /etc/snmp/snmpd.conf file, and run this :

Code: Select all

$ snmpwalk -v 1 -c yourcommunity yourip dsktable

Contents of snmp.conf file:

Code: Select all

rocommunity nexus
includeAllDisks

The suggested call doesn't return anything. I tried the two below and neither gave any response. Running without the dsktable gives plenty of output.

Code: Select all

snmpwalk -v 1 -c nexus 127.0.0.1 dsktable
snmpwalk -v 1 -c nexus localhost dsktable

What version of Net-SNMP are you using :

Code: Select all

$ snmpwalk -v 1 -c nexus 127.0.0.1 ucdavis.version

Does this look like what you need?

Code: Select all

$ snmpwalk -v 1 -c nexus 127.0.0.1 ucdavis.version
UCD-SNMP-MIB::versionIndex.0 = INTEGER: 1
UCD-SNMP-MIB::versionTag.0 = STRING: 5.1.2
UCD-SNMP-MIB::versionDate.0 = STRING: $Date: 2004/02/04 11:25:20 $
UCD-SNMP-MIB::versionCDate.0 = STRING: Fri Apr 21 13:14:52 2006
UCD-SNMP-MIB::versionIdent.0 = STRING: $Id: versioninfo.c,v 5.1.4.1 2004/02/04 11:25:20 slif Exp $

Well, this version work fine here (RH 4 Update 2 and CentOS 4.3).

Can you try to put this in /etc/snmp/snmpd.conf :

Code: Select all

rocommunity nexus
disk /

Restart the SNMP agent, and try agin this query :

Code: Select all

$ snmpwalk -v 1 -c nexus localhost dsktable

geefour · Post by **geefour** » Fri Apr 21, 2006 8:40 am

That produces this....

Code: Select all

snmpwalk -v 1 -c nexus localhost dsktable
UCD-SNMP-MIB::dskIndex.1 = INTEGER: 1
UCD-SNMP-MIB::dskPath.1 = STRING: /
UCD-SNMP-MIB::dskDevice.1 = STRING: /dev/sda2
UCD-SNMP-MIB::dskMinimum.1 = INTEGER: 100000
UCD-SNMP-MIB::dskMinPercent.1 = INTEGER: -1
UCD-SNMP-MIB::dskTotal.1 = INTEGER: 40313996
UCD-SNMP-MIB::dskAvail.1 = INTEGER: 36763120
UCD-SNMP-MIB::dskUsed.1 = INTEGER: 1502992
UCD-SNMP-MIB::dskPercent.1 = INTEGER: 4
UCD-SNMP-MIB::dskPercentNode.1 = INTEGER: 1
UCD-SNMP-MIB::dskErrorFlag.1 = INTEGER: 0
UCD-SNMP-MIB::dskErrorMsg.1 = STRING:

Certainly looks like an improvement!

Sometimes "includeAllDisks" in snmpd.conf doesn't work.

You just have to add every filesystem in snmpd.conf, like this :

Code: Select all

disk /
disk /usr
disk /var

In Cacti, reload the "ucd/net - Get Monitored Partitions" data query, and you'll be able to graph your filesystems.
