Basic startup

[adrianmarsh]

Hi,

I'm trying to integrate Cacti into an existing IIS/MRTG setup, without breaking the old one for now. The IIS server also runs some other www based tools like WebCalender.

When I enable the snmp dll in php.ini, I get the following message at the end of each php page (WebCalendar AND Cacti):

Cannot find module (IP-MIB): At line 0 in (none) Cannot find module (IF-MIB): At line 0 in (none) Cannot find module (TCP-MIB): At line 0 in (none) Cannot find module (UDP-MIB): At line 0 in (none) Cannot find module (SNMPv2-MIB): At line 0 in (none) Cannot find module (SNMPv2-SMI): At line 0 in (none) Cannot find module (UCD-SNMP-MIB): At line 0 in (none) Cannot find module (UCD-DEMO-MIB): At line 0 in (none) Cannot find module (SNMP-TARGET-MIB): At line 0 in (none) Cannot find module (SNMP-VIEW-BASED-ACM-MIB): At line 0 in (none) Cannot find module (SNMP-COMMUNITY-MIB): At line 0 in (none) Cannot find module (UCD-DLMOD-MIB): At line 0 in (none) Cannot find module (SNMP-FRAMEWORK-MIB): At line 0 in (none) Cannot find module (SNMP-MPD-MIB): At line 0 in (none) Cannot find module (SNMP-USER-BASED-SM-MIB): At line 0 in (none) Cannot find module (SNMP-NOTIFICATION-MIB): At line 0 in (none) Cannot find module (SNMPv2-TM): At line 0 in (none)



Second problem:

I've been able to scan a Foundry router, and specify the graph, but when I try to look at the graphs, theres no images created. Looking on the server I see that rra/ is empty.

I've also been a little confused by the instructions about how cactid is started, and how this ties into how the Scheduled Task works.

In the log file I'm getting :

First problem:

Cannot find module (IP-MIB) [etc]

Looks like you need to set the MIBDIRS environment variable.

Second problem:

rra/ is empty.
I've also been a little confused by the instructions about how cactid is started, and how this ties into how the Scheduled Task works.

What I understand is that cactid is started by poller.php, but only if cactid is selected as the "poller type" on the "poller" settings webpage. The scheduled task should always execute poller.php. If you have the poller type set to CMD.PHP, you don't need to worry about cactid.

Not sure about your log messages, there. Did you delete the localhost device? Cacti sets up a default device called 'localhost' and tries to do linuxy things to it; a step for removing this device should probably be included in the windows installation instructions. Turn the logging up to 'debug' and see what you get logged for POLLER and CMDPHP.

HTH, Rick

Right,

I fixed the first with a reboot (no idea what process didn't get restarted by an iis restart),

but the second issue is still there. Yes I've removed localhost as its a w2k machine not linux, but I'm still not getting rrd files, or any graphs, and only this in the log:

I've left the cactid out of the equation for now, using just cmd.php

[BSOD2600]

Which script are you using?

Turn the polling level in cacti to debug (Settings | Polling level) for one cycle and paste the output of the log file. If it contains WEBLOG entries, then don't bother posting since they just clutter up the log. Turn off WEBEVENTS logging and try again.

Just using the standard template (I've not written any scripts yet), with cmd.php in scheduled task. Still no files under rra.. The scheduled task ends with 0x0 status. Using a userid that is a local admin (the one I've used to create the cacti directory etc).

[adrianmarsh]

Hmm.. ok the rrd files are being created now (I had the incorrect version of rrdtool and just noticed the sticky). But still no graphs, just big red Xs where the graphs should be. What creates these ? Does it need a temporary directory with perms for IUSR... ??

I've tried turning on graph debug but don't see where the debug is shown. On the graph page itself it does say "RRDTOOL OK"

And running poller.php manually i get:

C:\Inetpub\wwwroot\cacti>php poller.php

I've also tried adding the IUSR account to the cacti parent directory with full write permissions, but still no graphs...



.....

A bit later on now. I've figured the logs out a bit. Now I see that it tries to run rrdtool to graph the image:

:\cactirrdtool\rrdtool.exe graph - --imgformat=PNG --start=-86400 --end=-300 --title="Cisco GGSN - CPU Usage" --rigid --base=1000 --height=120 --width=500 --alt-autoscale-max --lower-limit=0 --vertical-label="percent" --slope-mode DEF:a="C\:\inetpub\wwwroot\cacti/rra/cisco_ggsn_5min_cpu_11.rrd":5min_cpu:AVERAGE AREA:a#FF0000:"CPU Usage" GPRINTLAST:"Current\:%8.0lf" GPRINTAVERAGE:"Average\:%8.0lf" GPRINTMAX:"Maximum\:%8.0lf"

When I run this from the command line it doesn't produce anything. I've been reading about the cygwin dlls so I'll try that.

----------------

A little later, and I've figured out rrdtool needs c:\cactirrdtool in the system path, and from a cmd.exe prompt I can generate the binary of a png file. I've rebooted to load the new PATH environment into the IIS config, and subsequent processes, but still no graphs via the www... so I'm guessing NOW it must be permissions or something..

onward and upward..

[adrianmarsh]

A little further... I found that rrdtool still errored, complaining about ttfs :

H:\>c:\cactirrdtool\rrdtool.exe graph - --imgformat=PNG --start=-86400 --end=-30
0 --title="Cisco GGSN - CPU Usage" --rigid --base=1000 --height=120 --width=500

e\:%8.0lf" GPRINTMAX:"Maximum\:%8.0lf" > c:\a.png
ERROR: failed to load c:/windows/fonts/cour.ttf

I'm not sure why its looking for c:/windows as this is a W2K system and the windows directory is c:\winnt, but I've fooled it by creating c:\windows\fonts\ and putting courier there. Now no complaints on cmd.exe, but still no garphs through www.

--------------


GOT IT!!! I'd tried to add Ariel as the rrdtool ttf in the settings, but once I'd removed that and created the c:\windows\fonts directory then the pngs started showing!!

So - that just leaves why rrdtool needs c:\windows?? Maybe the way it was compiled? And also how can I override it in the settings (format / or \ ? )

[BSOD2600]

You should have specified a valid font file in the cacti path settings. Alternatively, you can create a system variable called RRD_DEFAULT_FONT and have it set to a valid font.

As I'm sure you're aware by now, rrdtool.exe creates the graphs. IUSR only needs read & execute permissions on it.

As for the cygwin dlls, I suggest you do a basic install of Cygwin. Then you will no longer need to worry about different cygwin dlls floating around your system.

[adrianmarsh]

Well I had specified c:\winnt\fonts\ariel.ttf, which should be valid and it didn't work... I'll look at the ENV variable method.

[BSOD2600]

I hope you meant c:\winnt\fonts\arial.ttf

[adrianmarsh]

You know... to be honest... I can't remember...

Anyway, I'm still having some issues (but at least not with the graphs), but they deserve a new thread...
