[SOLVED] Custom Data Query: No SNMP data returned.

Post by Guillem »

Hi all,

I'm just trying to get statistics data from vlan devices via iptables and I've got a "No SNMP data returned" error when cacti executes de query.

Client-side perl script to gathering data: cacti_ians_statistics.pl
Client-side snmpd config:
- exec .1.3.6.1.4.1.2021.50 iansstatistics /usr/bin/perl /opt/scripts/cacti_ians_statistics.pl -i
- exec .1.3.6.1.4.1.2021.51 iansstatistics /usr/bin/perl /opt/scripts/cacti_ians_statistics.pl -c
- exec .1.3.6.1.4.1.2021.52 iansstatistics /usr/bin/perl /opt/scripts/cacti_ians_statistics.pl -v
- exec .1.3.6.1.4.1.2021.53 iansstatistics /usr/bin/perl /opt/scripts/cacti_ians_statistics.pl -in
- exec .1.3.6.1.4.1.2021.54 iansstatistics /usr/bin/perl /opt/scripts/cacti_ians_statistics.pl -out
- exec .1.3.6.1.4.1.2021.55 iansstatistics /usr/bin/perl /opt/scripts/cacti_ians_statistics.pl -all

Can anybody help me? I suspect that problem is in perl client-side script. It returns the index as STRING in spite of INTEGER...

Hi gandalf,

Have you got any idea? Do you want that I make another check?

Thanks!

Please try this stripped down XML file and rerun Verbose Query

That starts to e a real problem. Either someone else should have a new idea or you should show me a wireshark trace of SNMP packets grabbed when "Verbose Query" is executed. BTB: Do you use net-snmp or php-snmp?

Definately Wireshark is the way to go on this one. The snmp walking routine cleans up just about everything.

Also please advise, are you using the php_snmp or leveraging net-snmp binaries to data collection?

Hi,

What information about Wireshark do you need? I've got to maintain client's privacy.

I've got PHP SNMP Support enabled, although I've got NET-SNMP installed too (and configured into Cacti's path settings). So, I don't know which one is really using cacti...

Thanks!


Edited 28/12/2007:
I get the following information from "Console -> Utilities -> Technical Support":
General Information
Date Fri, 28 Dec 2007 08:40:57 +0100
Cacti Version 0.8.7a
Cacti OS unix
SNMP Version net-snmp
RRDTool Version RRDTool 1.2.x
Hosts 28
Graphs 1977
Data Sources Script/Command: 5
SNMP: 22
SNMP Query: 1952
Total: 1979

So I suppose I'm using net-snmp...

Hi all,

finally I found the problem, it was on the SNMP timeout value.

Thanks!
