Graphs not appearing

[fsd]

Hi,

Just installed and configured cacti (latest version) along with other appropriate software such as net-snmp/php etc. I have created a new device to monitor, and cacti reads the SNMP info from it ok, however it does not create any images when i go to view the graphs - see attached picture.

Thanks

seem to have found something which may be causing it, part is in bold

Code: Select all

C:\rrdtool\rrdtool.exe graph - \
--imgformat=PNG \
--start=-604800 \
--end=-1800 \
--title="localhost - Used Space - A:" \
--rigid \
--base=1024 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label="bytes" \
--slope-mode \
[b]DEF:a="c\:\files\dev\cacti/rra/localhost_hdd_total_10.rrd":hdd_total:AVERAGE \
DEF:b="c\:\files\dev\cacti/rra/localhost_hdd_total_10.rrd":hdd_used:AVERAGE \[/b]
AREA:a#002A97:"Total"  \
GPRINT:a:LAST:"Current\:%8.2lf %s"  \
GPRINT:a:AVERAGE:"Average\:%8.2lf %s"  \
GPRINT:a:MAX:"Maximum\:%8.2lf %s\n"  \
AREA:b#F51D30:"Used"  \
GPRINT:b:LAST:" Current\:%8.2lf %s"  \
GPRINT:b:AVERAGE:"Average\:%8.2lf %s"  \
GPRINT:b:MAX:"Maximum\:%8.2lf %s\n" 

where it lists c:\:\files etc, obviously seems wrong..how change i change this setting?

after running what i posted above manually, it simply reports that it cannot find the rrd file. when checking the rra folder, there is only a .placeholder file. have tried deleting/readding device to no avail.

The default templates are for unix/linux machines. You need to 1) enable snmp on your Windoz box 2) Delete the localhost device 3) Add a new device utilizing snmp with host template "Windoz" 4) Create graphs.

1) enable snmp on your Windoz box

Have done, i can query it without an issue.

2) Delete the localhost device

Have done.

3) Add a new device utilizing snmp with host template "Windoz"

Have done.

4) Create graph

Have done.

There is no errors/problems throughout the whole process, everything appears to have worked until it comes to viewing the graphs..

The post where i pasted code, the real hostname was replaced with localhost for security reasons, sorry if that caused confusion, i am definitely querying a LAN address, not localhost.

Make sure your rrdtool version is correct: "Settings->General"

Checked that, using rrdtool 1.2 and cacti is set to use 1.2 as well

Just to make things interesting, i installed and configured a new installation on a remote windows server 2003 box. followed the cacti.net install instructions, deleted localhost template, added a new device (which cacti retrieved the info from ok) told it to create the graphs, arranged them into the default tree. when viewing the graphs, they are listed, but there is no images to speak of, and nothing except .placeholder in c:/dev/www/cacti/rra/

either my config is screwed, or cacti has a nice big bug...suggestions are welcome

Goto Settings->General and set logging to Debug. Then, when your scheduled poller task runs next you should be information in the Log. Post that data.

Optionally, you can simply run the following sequences of commands from a command line:

php <path_cacti>/cmd.php

and

php <path_cacti>/poller.php

Please also insure that your have the correct Paths under Settings->Paths that include the entire path including the file name/extension.

If you are runninng PHP 5.x, make sure that your setting for the PHP Path is PHP-WIN.EXE.

Last thing, make sure that you have the correct PHP Extensions loaded:

PHP -M

MySQL
Sockets
SNMP

fixed it, going back to rrdtool 1.0.49 and changing cacti to use the correct version. When using rrdtool 1.2.10 it did not work at all, now rra files are created and graphs appear perfectly!

Hi guys, i'm having this problem in a FreeBSD Box.

Everything seems to be ok, but the graphs simply don't appear.

I instaled PHP, Mysql, net-snmp, rrdtool...

Now I'll check the modules as listed above, and then I'm thinking to reinstall PHP and RRDtool.

Thankx

Hi, the problem is still boring me, i recompile from source php 5.0.4, and in the modules section it appears all the needed modules, mysql, sockets, snmp... now i will update the rrdtool, i think that it is the font of my problems... by the way, how i do the test to see what rrdtoll is doing... rrdtool info did'nt work
