Generating charts.. no dice

[jt]

Sorry if this is a really stupid question. I've tried for almost a full day to figure out what the problem is, and i exhausted everything.

I have successfully installed rrdtool using it's scripted install (which was a chore by itself to recognize everything), i then install cacti, but right as I do it immediately tells me it cannot find rrdtool. it says you can manually enter the path, but I knew at that point i was going ot have a problem.

my paths are correct, and i know snmp is working becuase I installed MRTG just so I could poll the info to verify it's working. You can see that working here:
http://www.e-places.net/mrtg/webs.shtml

When i go to generate graphs in debug the only message i get is 'snmp error'

this is an Ensim server running Fedora core 1. Dual CPU AMD 2000 with 2GB RAM and 2x 120GB drives. <--just incase, but I don't imagine that matters.

any help is greatly appreciated.

Is your SNMP community set correctly? What does an snmpwalk return?

[jt]

I appreciate the reply.

yeah snmp walk works.

course that command just brings back the help menu. but it definitely works.

It brings up the help menu because you are not giving it a community name or an oid but that doesn't mean snmp is working. I know you said you had MRTG working but just for testing, try this. Presuming that the community name is 'public' and substituting 'ip address' for the ip of the system, try:

snmpwalk -c public -v 1 'ip address' system

If you get a valid snmp answer then we can go from there. If you get a no response error then the community is probably wrong. If you get unknown host then the ip is probably wrong. If you get the help menu then the command is probably wrong.

[jt]

I guess I should have clarified a little. I do know snmp is working, but i should have mentioned something about the help menu before. I knew it would bring that up becuase there were no arguments. Know what I mean?

Here's the MRTG chart I put up to test:

Let me go one step further on this.

Just for testing i wanted to make sure that rrd was working. I ran through their short tutorial and copied the results

http://www.e-places.net/rrd/speed.html


So i do know the functions of rrdtool themself work.

Not that this probably helps at all.

[jt]

I started over from scratch. Installed Cacti on the root of the server so I can eliminate any ensim issues.

Install ran fine, it went green on all paths and found everything.

it STILL returns the same snmp errors. but I know for sure it found rrd

Code: Select all

FYI I have also tried to apply this however the option does not exist.

If you have files in your 'rra/' directory, but your graphs still appear as broken images, you should enable graph debug mode see exactly why the graphs are not rendering. To do this go into Cacti, select Graph Management from the menu, select any graph listed, and select Turn On Graph Debug Mode.

Revert to the 0.8.6c version of lib/snmp.php and post results.

Thanks for the reply.

No change. Now just to clarify, the only file altered was the snmp.php file itself in the var/www/html/cacti/lib directory;

result:

Code: Select all

+ Running data query [1].
+ Found type = '3' [snmp query].
+ Found data query XML file at '/var/www/html/cacti/resource/snmp_queries/interface.xml'

Also, while I did not touch on it before, the rra dir is being populated and updated at the 5 minute intervals i set the cron to. However, those files sizes never change.

Also, when I click on 'add devices' i see in green letters 'UP" on each device. and it shows a min and max. so somewhere it's seeing the device itself.

Please run "php -m" and verify that php_snmp is loaded. If not, please insure that Settings->Paths snmpwalk and snmpget are accurate paths.

Hello,

yes I verified those yesterday, and again just now. they work.

Here's something VERY strange.

I figured I'd export the images to a website and just see what happened.

the export worked fine, creating the html, and all images correctly. (they're useles graphs right now, but they work, which is all I care about)

However, they still do not show up in the cacti program itself.

http://www.e-places.net/cacti/

[TheWitness]

You are supposed to schedule the export every "X" minutes and then direct the users to the exported data. With the timespan selector, it is impossible to have that real time.

TheWitness

[jt]

yes I understand that part. what I mean though is even though the graphs show up where they're exported to, they do not show up inside the cacti program still. the only way to view any charting is to look at the exports.

[TheWitness]

That's odd.
