Stuck at Cacti Installation Guide

[cboyd213]

for my peplink if I go to: Create Graphs for this Host

It shows:
Data Query [SNMP - Interface Statistics]
This data query returned 0 rows, perhaps there was a problem executing this data query. You can run this data query in debug mode to get more information.

What does this mean please?

[gandalf]

It is already set to SMMP only

But the screenshot shows "Ping and SNMP". What is correct, then?

Sorry what I should have said is that I changed it to SNMP after I sent the screenshot and before you sent me the post

PEPLINK:
Associated Graph Templates
Graph Template Name Status
1) ucd/net - Memory Usage Not Being Graphed

when I click "Create Graphs for this Host"
I see:


For Web-FTP Server 03:

1) Host MIB - Logged in Users Not Being Graphed
2) Host MIB - Processes Not Being Graphed

when I click "Create Graphs for this Host"
I see:

In fact, this is the reason why the table of interfaces is empty in your last post. Core reason is

+ Executing SNMP walk for list of indexes @ '.1.3.6.1.2.1.2.2.1.1'
+ No SNMP data returned

In other words: cacti did an snmpwalk on OID '.1.3.6.1.2.1.2.2.1.1' and did not receive any answer. But from

snmpwalk -c crazycharter -v 2c 192.168.4.1 interface
IF-MIB::ifNumber.0 = INTEGER: 4
IF-MIB::ifIndex.1 = INTEGER: 1
IF-MIB::ifIndex.2 = INTEGER: 2
IF-MIB::ifIndex.3 = INTEGER: 3
IF-MIB::ifIndex.4 = INTEGER: 4
IF-MIB::ifDescr.1 = STRING: LAN
IF-MIB::ifDescr.2 = STRING: WAN1
IF-MIB::ifDescr.3 = STRING: WAN2
IF-MIB::ifDescr.4 = STRING: WAN3
...

you found that the device is responding to a plain manual snmpwalk, showing indeed the interface index list.
So there MIGHT be a problem with the php-snmp code.

Please first verify, whether you are using php-snmp or plain net-snmp libraries. Visit the System Utilities to find all system information. If php-snmp is used, please de-install it and retry.
Reinhard

[cboyd213]

Looks like both:

Running
net-snmp - 1:5.3.1
net-snmp-libs - 1:5.3.1
net-snmp-utils - 1:5.3.1
php-snmp - 5.1.6

I did reinstall php-snmp but it toke cacti with it so I also had to install cacti back
Still getting the same error message

Also I tried setting up a graph for my server 03 box and getting:

RRDTool Says:

[gandalf]

If everything else fails, let's do a code change.

First, please copy lib/snmp.php to lib/snmp.php.save.
Then, please edit lib/snmp.php and find function snmp_get_method. Change all occurences of SNMP_METHOD_PHP to SNMP_METHOD_BINARY and retry.

This will force cacti using net-snmp libraries instead of php-snmp, but without deinstalling php-snmp.

Thanks for your with this but I tried it and it's still gaving me the same error:

[gandalf]

Please let's stick for the moment with Verbose Query. This step comes first. So we have to resolve it prior to anything else.
Reinhard

[cboyd213]

not sure what you mean
Are you talking about the error I'm getting on the peplink

Data Query Debug Information

+ Found type = '3' [snmp query].

I'm not having a data probelm when I add my server 03 box to cacti

[gandalf]

Yep. Does the behaviour change if my last recommendations are met?
Reinhard

[cboyd213]

Nope. Same error

[pdt256]

I am having the same problem. I run the Verbose Query for SNMP - Interface Statistics on my PePLink router:

Code: Select all

+ Running data query [1].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/usr/local/src/cacti-0.8.7b/resource/snmp_queries/interface.xml'

+ Found data query XML file at '/usr/local/src/cacti-0.8.7b/resource/snmp_queries/interface.xml'

However, when I run a snmpwalk from the Linux command line everything is returned fine.

Code: Select all

$ snmpwalk -v 2c -c public 192.168.1.100 .1.3.6.1.2.1.2.2.1

IF-MIB::ifDescr.3 = STRING: WAN2
IF-MIB::ifType.1 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.2 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.3 = INTEGER: ethernetCsmacd(6)

[/code]

[gandalf]

With 087b, Cacti performs

Code: Select all

snmpbulkwalk -c ... -v 2c -O Qn -Cr50 ... <host> <OID>

Please try this on your target.
An assumption would be, that the target does not support snmpbulkwalk.
Using 087b, a workaround would be to use SNMP V1; cacti will use snmpwalk, then.
Or check out 087c BETA1. This version allows using SNMP V2c. In this case, when setting the maximum number of OIDs to 1 for this host, cacti will automatically switch to using snmpwalk instead of snmpbulkwalk
Reinhard

[pdt256]

Switching to SNMP v1 worked great. Thanks for the quick response.

[gandalf]

Glad to hear this. So 087c would definitively be good for you
