Hi,
i'm searching since a few of hours, but i can't find my problem....
..
cacti is connecting threw smtp

C\:\apache\xampp\htdocs\cacti/rra/localhost_hdd_total_20.rrd

The rrd files does exists...

RRDTool Says:

OK

running on w2k3 with the most up to date files (installed monday).
collcting through cactid, rra's get created.

strange thing is though: my graph does not get created at all (ie shows broken graph symbol).

I think the next Failure is here:
--
DEF:a="E\:\cacti/rra/rm2r01_5min_cpu_21.rrd":5min_cpu:AVERAGE \
--
The "" in PHP skips the next letter - so it can't find the file..
But where can i change the adress url? I searched everywhere :-|
The files exists, but i can't read it..

---------------------- EDIT ----------------
Check your RRDtool version
just run the rrdtool in the commandline
--
check the version which is set in the webinterface under "Settings"
--

Yes, your problem is the double back slash being used in your path. I've seen this before, but offhand forget how it was fixed and can't find the post

Go to your settings and paste all your paths.

c:/apache/rrdtool/rrdtool.exe
c:/apache/xampp/php/php.exe
c:/apache/xampp/htdocs/cacti/log/cacti.log
c:/apache/cactid/cactid.exe

But i think it is NOT the Problem:
Because the URL is setted in the include/config.php line 58

Code: Select all

$config["base_path"] = ereg_replace("(.*)[\/\\]include", "\\1", dirname(__FILE__));

Outputs the
--

--
after change to
C:/apache/xampp/htdocs/cacti
with

Code: Select all

$config["base_path"] = str_replace("\\","/",$config["base_path"]);

(insert the code in the next line)

It shows the Graphik, but it is empty! as the screenshot on top!

rrdtool version: 1.2.10 (the one from the cacti website).
version set in cacti: 1.2

paths:
snmpwalk=e:\net-snmp\bin\snmpget.exe
snmpget=e:\net-snmp\bin\snmpget.exe
rrdtool=e:\rrdtool\rrdtool.exe
rrdtool-font=c:\windows\fonts\arial.ttf
php=e:\php\php.exe
log=e:\cacti\log\cacti.log
poller=e:\cactid\cactid.exe

the poller is set to cactid and to use icmp and snmp
i added a system variable RRD_DEFAULT_FONT=C:\WINDOWS\FONTS\ARIAL.TTF

rrdtool does create a graph when run directly from prompt (though it seems empty, but i will check on that problem later on my installation).

EDIT:
if fixed that problem.... i forgot to set the rights to cmd.exe in the system path because i thought if i place it into the cacti folder it will be run from there.

EDIT2:
now the graphs work perfectly :-) so my(!) problem was only a permission-problem. tnx anyways...

REQUEST:
wouldnt it make more sense to not let cacti directly access cmd.exe and instead let cacti use a cmd.exe which can be copied to some defined place?
also, is cmd.exe really needed to run rrdtool? i only wonder because im using routers.cgi at the moment, and with that i do not have to set permissions to cmd.exe for the iusr.

For my cacti web site, I created a seperate user, which I gave rights to cmd.exe along with the cacti files. IUSR has no rights to these files. Not the best, but it keeps things a little bit seperated.

The Threads of the CMD :

C:\apache\xampp\php\php.exe c:\apache\xampp\htdocs\cacti\cmd.php

are N/A:

#!/usr/bin/php -q
08/05/2005 11:55:03 - CMDPHP: Poller[0] Time: 2.8666 s, Threads N/A, Hosts: 1

is this normal?
----------------------------
Cactid returns:
Notification LOG MIB: Module not Found
NET-SNMP-Agent-MIB: Module not Found
---------------------------
The Mibs are @ C:\USR\mibs
is this right?

thx sim

Hi

Code: Select all

Maximum Threads per Process
The maximum threads allowed per process. Using a higher number when using cactid will improve performance. NOTE Applies only to CACTID!

Are you using cmd.php or cactid ?

Please note that in rrdtool the syntax "C\:\myfolder/whatever.rrd" is expected.
