WARNING: Result from SNMP not valid

Post by pyroblade »

Hi everybody,

It's my first post.
I'm encountering some difficulties with Cacti, I searched and tried debugging 2 days before posting but I don't know what to do now...

My environnement :
  • OS : RHEL4
    Cacti : Version 0.8.7b
    Poller : spine
    PHP : 5.2.4
    MySQL : 5.0.45

    SNMP :
    net-snmp-libs-5.1.2-11.EL4.10
    net-snmp-utils-5.1.2-11.EL4.10.0.1
    perl-Net-SNMP-5.2.0-1.2.el4.rf
    net-snmp-devel-5.1.2-11.EL4.10
    net-snmp-5.1.2-11.EL4.10.0.1
I have made an xml template to retrieve the temperature of CPU's AIX Blades from a Management Module... with REGEXP expression to get only numeric output

Code: Select all

First, I thought that my xml wasn't good.
I had this error messages :

I had this code to my xml, in order to print the result.

Code: Select all

                <bladeTEST>
                        <name>Blade TEST</name>
                        <method>walk</method>
                        <source>VALUE/REGEXP:^\+([0-9]{2,3})\..*$</source>
                        <direction>input</direction>
                        <oid>.1.3.6.1.4.1.2.3.51.2.22.1.5.3.1.17</oid>
                </bladeTEST>
My REGEXP seems to work, but there's a strange result because I think it didn't recognize the oid index "BladeID":

Image

I change the xml (without the REGEXP), and the half of the returned value had disappear but the returned values still not associated with "BladeId" :

Code: Select all

                <bladeTEST>
                        <name>Blade TEST</name>
                        <method>walk</method>
                        <source>value</source>
                        <direction>input</direction>
                        <oid>.1.3.6.1.4.1.2.3.51.2.22.1.5.3.1.17</oid>
                </bladeTEST>
Image


The original value is a string like : "CPUx Temp = +xx.xx Centigrade"
Cacti return : +xx.xx Centigrade

It seems like Cacti don't like "=" in the returned value, am I right ?
Someone could help me ?

PS : Sorry, my post is heavy but I think I had to give all the elements I had :o

Yes, I'm quite sure the "=" breaks it

Should I open a bug ?

Do you think the problem is in this function (lib/snmp.php) :

Code: Select all

function format_snmp_string($string) {
        /* strip off all leading junk (the oid and stuff) */
        $string = trim(ereg_replace(".*= ?", "", $string));
...
...

Yep. If you can work out a better code, I'll happily accept it
