Unusual Problem

[sayasif]

HI

Basic info,

I got latest cacti on w2k running fine. I added snmp support by putting snmp binaries like get, walk etc in usr/bin directory. I had some problems with MIBS as they were giving unable to link when I ran cmd.php, which i traced down to some notificationgroup entry under snmpv2-mib.txt file , so I deleted taht line and there wasn't any problem for the errors. So now when I query for an OID by snmpget then I do get the value back !

Now the problem,

Cacti is collecting the OID value but not putting it on graph, in other words the graphs are blank. Data is definately there, as when I put a keyword in legend with <octets> I do see the value printed but no the graph

Following is a sample configuration for graph which is getting CPU utilization in percentage from a remote system


c:/rrd/rrdtool.exe graph - \
--imgformat=PNG \
--start="-86400" \
--title="NTIIS CPU01 Utlization" \
--rigid \
--base=1000 \
--height=150 \
--width=500 \
--upper-limit=100 \
--lower-limit=0 \
--vertical-label="Percentage" \
DEF:a="e\:/cacti/rra/ntiiscpu01.rrd":ntiiscpu01:AVERAGE \
AREA:a#7CB3F1:"4


Can anyone pointout the problem? Has it got anything to do with the change I did in the SNMPV2.mib . confused as of now.

I would appreciate any help

thanx

Have you tried to use the numeric OID ? (1.2.3.5 etc.) Also check that the octet-size you polling is not exceeding the max set in the RRA-settings, else they will be discarded, and thus producing a graph with no values.

HI and so many thanx for giving that hint.. that WAS the problem, it was 1 initially so i change it to 100 and it works !!

any idea of this particular thing in the graph source

DEF:a="e\:/cacti/rra/ntiiscpu01.rrd":ntiiscpu01:AVERAGE \
DEF:a="e\://cacti/rra/ntiiscpu01.rrd":ntiiscpu01:AVERAGE \

is it right either way I mean the forward slashes that comes after "e" , e being my drive letter.

one last question

I got cygwin installed on my system, so that I can use the awk and grep utils, so that I can use the contrib scripts provided. how do I interface the contrib scripts to go to the bash shell , If somebody can show one example it would be really helpful for all those who want to get it done ..

thanx again for ur help

Im glad it worked for you

I think you should use forward slashes on win32 (c:/foxserv/www....), i know it works 100%. Although I have seen those variations you wrote....

DEF:a="e:/cacti/rra/ntiiscpu01.rrd":ntiiscpu01:AVERAGE \

Sorry i dont know much about cygwin, so i cant help you there ;(
