pure SNMP Replacement for SNMP - Get Processor Information

[gandalf]

This is a pure (aka FAST) replacement of standard "SNMP - Get Processor Information".
It uses advanced SNMP Data Query XML options to provide not only the data required, but the name of the processor found!
Be prepared, that not all SNMP implementations provide data for this query. Even worse, I encountered some hosts that respond well to query indexing but don't provide the hrProcessorLoad itself.
To verify this, please run snmpwalk against .1.3.6.1.2.1.25.3.3.1.2. If no data found, please update SNMP on the target host!

I'm a problem at the creation of rra files

In graph mangement i have this :

RRDTool Command:

/usr/bin/rrdtool graph - \
--imgformat=PNG \
--start=-86400 \
--end=-300 \
--title="CAB-S03 - hrProcessorLoad |query_hrProcessorFrwID|" \
--base=1000 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label="Load" \
--slope-mode \
--font TITLE:12: \
--font AXIS:8: \
--font LEGEND:10: \
--font UNIT:8: \
DEF:a="/var/www/cacti/rra/cab-s03_load_83.rrd":load:AVERAGE \
COMMENT:"CPU\: |query_hrDeviceDescr|\n" \
AREA:a#FF0000FF:"Load" \
GPRINTLAST:"Current\:%8.2lf %s" \
GPRINTAVERAGE:"Average\:%8.2lf %s" \
GPRINTMAX:"Maximum\:%8.2lf %s\n"
RRDTool Says:

ERROR: opening '/var/www/cacti/rra/cab-s03_load_83.rrd': No such file or directory

AND in data sources i have this :

/usr/bin/rrdtool create \
/var/www/cacti/rra/cab-s03_load_83.rrd \
--step 300 \
DS:load:GAUGE:600:0:120 \
RRA:AVERAGE:0.5:1:500 \
RRA:AVERAGE:0.5:1:600 \
RRA:AVERAGE:0.5:6:700 \
RRA:AVERAGE:0.5:24:775 \
RRA:AVERAGE:0.5:288:797 \
RRA:MAX:0.5:1:500 \
RRA:MAX:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797 \

Cactiuser have all rights and i have chmod 777 -r on rra, log and ressources directory.

Please help me

[gandalf]

Did you run the snmpwalk against the OID given in my first post? Please post results
Reinhard

[diablo62]

I've

HOST-RESOURCES-MIB::hrProcessorLoad.3 = INTEGER: 0
HOST-RESOURCES-MIB::hrProcessorLoad.4 = INTEGER: 0

I think it's good. No ?

[gandalf]

Hmm, please try .1.3.6.1.2.1.25.3.3 now and post the whole stuff
Reinhard

[diablo62]

I'm sorry, i have been on holiday

for oid .1.3.6.1.2.1.25.3.3
I have :
snmpwalk result
HOST-RESOURCES-MIB::hrProcessorFrwID.3 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorFrwID.4 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorLoad.3 = INTEGER: 0
HOST-RESOURCES-MIB::hrProcessorLoad.4 = INTEGER: 0

Is this the only graph for that device? What is the devices status (from device list)? Are you running cmd.php or spine?
Reinhard

[diablo62]

I have only one graph for this device and i use cmd.php
I don't know it does'nt want to create the rrd file

[gandalf]

You didn't answer to the question about the hosts's status. I fear it is either down or undefined. This is normally a hint for a problem with downed device detection for that host. Please select SNMP as downed device detectionmethod and retry
Reinhard

[diablo62]

I ve check all device are up i have delete graph and data sources but it's the same problem it can't create the rrd file but he have all right (777) on the directory

[Savages]

i did not import the scripts yet, but i was wondering. I have the following output on a SNMP-walk, system is a Compaq dx2300 running Windows XP:

Code: Select all

snmpwalk -v2c -c <community> <ipadres> .1.3.6.1.2.1.25.3.3
HOST-RESOURCES-MIB::hrProcessorFrwID.6 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorFrwID.7 = OID: SNMPv2-SMI::zeroDotZero
HOST-RESOURCES-MIB::hrProcessorLoad.6 = INTEGER: 0
HOST-RESOURCES-MIB::hrProcessorLoad.7 = INTEGER: 0
ssorLoad.7 = INTEGER: 0

Is this enough output to be usefull?

[Kro]

gandalf, what values should we put here ?

[gandalf]

How did you get to that page? It is not supposed to pop up anywhere
