Post installation configuration SNMP ERROR and php problem

[cacti_novice]

Hi,

I've just installed cacti-0.8.6 with all the necessary libs, and i can't get it graph any information.

After reading lots of topics in the forum, i didn't find out the answer to my problems.

I'm actually having two visible troubles:

• SNMP error for my localhost

• can't execute poller.php manually to see what's wrong:

Code: Select all

php poller.php 
sh: line 1: /usr/local/php/bin/rrdtool: No such file or directory

Here, i can't figure out why is he looking for rrdtool in this path !

Thanks for any help from you !!

Obviously, there's a problem with the paths... executing cmd.php gives this output:

Code: Select all

php cmd.php 
sh: line 1: /usr/local/php/bin/snmpgetnext: No such file or directory
05/25/2007 04:10:02 PM - CMDPHP: Poller[0] Time: 0.0101 s, Theads: N/A, Hosts: 1

About the snmp configuration, the execution of snmpwalk as follows gives back a lot of information.

Code: Select all

snmpwalk -cpublic -v1 localhost
SNMPv2-MIB::sysDescr.0 = STRING: Linux xxxxxx 2.4.21-20.EL #1 Wed Aug 18 20:58:25 EDT 2004 i686

SNMPv2-MIB::sysORDescr.1 = STRING: The MIB module to describe generic objects for network interface sub-layers

......

These are further details about my problem hope that will help you to help me

RRD Files are now generetaed.

Browsing graphs in cacti interface, all data are NaN.
Then i verified if limits were NaN, that was not the case but every collected value is NaN:

/usr/local/rrdtool-1.2.23/bin/rrdtool fetch localhost_proc_24.rrd AVERAGE

Code: Select all

1180282500: nan
1180282800: nan
1180283100: nan
1180283400: nan
1180283700: nan
1180284000: nan
1180284300: nan
1180284600: nan
1180284900: nan
...

Any clue for this trouble ?
Thanks again for reading and maybe helping !

normally one would log into cacti and go to settings, then paths, and make sure the links there actually point to where your executibles are.

ie: /usr/bin/snmpwalk

[cacti_novice]

Paths are correct... when executed manually, i have polling.
But i have to execute cmd.php prior to poller.php... if only poller.php is executed, then i have no data.

[iYRe]

use cactid ?
