graph but no value

[itobald]

hi all,

i have a problem with my snmp query in xml. I try to check the number of used and free addresses on my Windows DHCP (it's on an Active Directory server). All seems to work correctly but when i check my graph, there aren't any value. So i need a little help to understand my problem.

i have attached my query in XML and the debug of my graph.

Thanks

Please see 2nd link of my sig for debugging

i check all parameters in your sig and all seems ok.

I check the poller cache and i see something weird. OIDs don't use the value of the index of the request.

Normally, i must have .1.3.6.1.4.1.311.1.3.2.1.1.2.192.168.1.0 in my poller cache but i have .1.3.6.1.4.1.311.1.3.2.1.1.2.0.

I think there is a problem with my snmp query but i don't see it.
Have you any idea?

Thanks

What does Verbose Query on that Data Query return?
R.

Verbose Query returns:

Code: Select all

What is the result on snmpwalk against 1.3.6.1.4.1.311.1.3.2.1.1.1.192.168.1.0?
Currently, you seem to have an index of "0" out of that instead of a "192.168.1.0". This might require an OID/REGEXP parse

The result of snmpwalk is :

Code: Select all

administrateur@srv-cacti:~$ snmpwalk -c tcom_sup -v 2c 192.168.1.1 1.3.6.1.4.1.311.1.3.2.1.1.1.192.168.1.0
SNMPv2-SMI::enterprises.311.1.3.2.1.1.1.192.168.1.0 = IpAddress: 192.168.1.0

[gandalf]

That is as expected.
Nevertheless, cacti may have trouble with the dotted data.
Please try OID/REGEXP as suggested above instead

Thanks a lot. It works, i have another problem but just with my scale.
I think i can find a solution on the forum.

[itobald]

i don't find any solution on the forum so i explain my problem here but i can create a new subject for this.

When i see my graph, values are not integer and they are multiplicated by a constant. (3.333). I think there is a probleme with my graph template or my data template because snmp request works fine (get the good OID).

have you any idea?

[gandalf]

RRDTool stores COUNTERs as "per second" values. You may want to multiply with your polling interval to get the "basic" value. But please study rrdtool consolidation to understand, waht happens. See 1st link of my sig, rrdtool chapter
