SNMP - Get Processor Information

Post by Brujo »

hi together,

i get no results at Associated Data Queries for the SNMP - Get Processor Information - Success [0 Items, 0 Rows]


the Verbose Query output looks like
Data Query Debug Information

+ Running data query [9].
+ Found type = '4 '[script query].
+ Found data query XML file at '/home/htdocs/cacti/resource/script_queries/host_cpu.xml'
+ XML file parsed ok.
+ Executing script for list of indexes '/usr/bin/php -q /home/htdocs/cacti/scripts/query_host_cpu.php 82.165.34.54 public 1 index'
+ Executing script query '/usr/bin/php -q /home/htdocs/web0/html/system/cacti/scripts/query_host_cpu.php 82.165.34.54 public 1 query index'
any hint ?

Can you walk .1.3.6.1.2.1.25.3.3 with snmpwalk? This is the processor table that the script looks at.

Did you try running the script(s) on the command line ?

When I try a

on a single cpu host I only get back
HOST-RESOURCES-MIB::hrProcessorFrwID.1 = OID: SNMPv2-SMI::zeroDotZero

but on a multi processor machine I get..
HOST-RESOURCES-MIB::hrProcessorFrwID.1 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorFrwID.2 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorFrwID.3 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorFrwID.4 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorLoad.1 = INTEGER: 6
HOST-RESOURCES-MIB::hrProcessorLoad.2 = INTEGER: 5
HOST-RESOURCES-MIB::hrProcessorLoad.3 = INTEGER: 2
HOST-RESOURCES-MIB::hrProcessorLoad.4 = INTEGER: 4

Seems that processorload only works on multi cpus ?

no - I've tried it on single-cpu machines. You should see both the FrwID, and the Load. This is why Cacti is not working properly... somthing in your snmp is not configured properly or something. It should be reporting the cpu load through that oid. If you can find another place where the cpu load is measured (a manufacturere specific oid perhaps) then you can use the generic oid templates, or write your own script to make a cpu load graph.

I have the same problem, but with a right snmpwalk.

I use the last cacti : cacti-0.8.6b-1.

Data Query Debug Information
+ Running data query [9].
+ Found type = '6 '[script query].
+ Found data query XML file at '/var/www/html/cacti/resource/script_server/host_cpu.xml'
+ XML file parsed ok.
+ Executing script for list of indexes '/usr/bin/php -q /var/www/html/cacti/scripts/ss_host_cpu.php 192.168.1.84 public 2 index'
+ Executing script query '/usr/bin/php -q /var/www/html/cacti/scripts/ss_host_cpu.php 192.168.1.84 public 2 query index'
+ Found data query XML file at '/var/www/html/cacti/resource/script_server/host_cpu.xml'
+ Found data query XML file at '/var/www/html/cacti/resource/script_server/host_cpu.xml'
+ Found data query XML file at '/var/www/html/cacti/resource/script_server/host_cpu.xml'

It's ok.

snmpwalk :
# snmpwalk 192.168.1.84 .1.3.6.1.2.1.25.3.3
hrProcessorFrwID.7 zeroDotZero
hrProcessorLoad.7 15

And manually :
# php /var/www/html/cacti/scripts/ss_host_cpu.php 192.168.1.84 public 2 index
#

Nothing :(

I dunno why i have "2 index", but if i do :
# php /var/www/html/cacti/scripts/ss_host_cpu.php 192.168.1.84 public 1 index
0
#

I have 0 in result.

Note that :
# php /var/www/html/cacti/scripts/ss_host_cpu.php 192.168.1.84 public 2 query index
# php /var/www/html/cacti/scripts/ss_host_cpu.php 192.168.1.84 public 1 query index

If you check out the host template "ucd/net SNMP Host" it will give you a lot more information when using UCP/NET SNMP on linux.

I too am having this problem: "SNMP - Get Processor Information" always returns 0 rows. I have tried this on two separate boxes without success. In both cases, my results are like the following:

Code: Select all

$ snmpwalk -v1 -cpublic localhost | grep Processor
HOST-RESOURCES-MIB::hrDeviceType.768 = OID: HOST-RESOURCES-TYPES::hrDeviceProcessor
HOST-RESOURCES-MIB::hrProcessorFrwID.768 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrSWRunParameters.28242 = STRING: "Processor
This of course leads me to believe it is an SNMP configuration issue since SNMP isn't reporting any processor load information. What configuration options should I be checking for?

My /etc/snmp/snmpd.conf is very simple:

Code: Select all

rocommunity  public
syslocation  "... my location ..."
syscontact  "... my contact info ..."

I read this from net-snmp sourceforge bug tracking page:
2002-11-08
Note that although the Host Resources table includes a
hrProcessorTable,.... it doesn't calculate the
hrProcessorLoad value correctly, and either returns
a dummy value (based on the load average) or nothing
at all.

Providing a realistic (and accurate) value for this object
would require constant polling within the agent, and it has
been felt that doing so would put an unacceptable load on
the agent, for an insufficient benefit.
So, no hrProcessorLoad entity is available on net-snmp. (but the date of this post is very old, I don't know the situation actually but I guess it's the same)
