graph is drawn only once at the beggining

[filipn]

After configuration and constructing first graphs I only get a part of graph.. after minutes/ hours there is only a poart of graph that was created after deploying it.. what can be wrong ?

RRDTool Command:

/usr/bin/rrdtool graph - \

RRDTool Says:

OK

[daibosatsu]

Does your graph data say NaN or something?

[filipn]

Yes it is ! As I can see that values NaN on the graphs, only on the beggining in firs 5 minutes of working i see a graph , and after that i do not receive any grapfh

I will give additional information shortly !

Thanks much for your interest in my worries

for poller you're using cmd.php or spine?
And did you made them excutable?
And what's the interval of your poller if you're using spine? I am setting it at 5 minutes.
And what is your linux user account use to run cacti?

I am using cmd.php
Yes, cmd.php has appriopriate priviledges.
5 minutes for polling.
User cacti in cacti group.

As I made it one more time, graph generated only a smart part of itself (was being drawn only for 5- 10 minutes) and now is not drawing anything new.

without any warnings/errors.

And in Graph managment RRDTool says ok, but the graph is only drawn with a small part of it ( made on the begining of polling ).

My devise is Up, with availability 100, and current/average information. What is more verbose queires also show data.

Stuck in it.. ;(

Switched to debug mode, eveythign seems to be fine with data,... but still no graph generated :/

guys, I believe that this is known problem.. omg, just dying wit it


thanks for your time !

hmm strange, can you post your crontab? And which version you're running?

[filipn]

/etc/cron.d/cacti

*/5 * * * * cacti /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1

/etc/crontab

nothing.

// question, which "cron" should be filled with the command for poller ?

information from tech support :

so yes, pretty awasome, by time to time poller is broken, empty graphs with nan values and sometimes :

damnly stuck, just reading google

hey mate, thanks for being with me =)

[filipn]

when I do :

su cacti

and then php .../poller.php

iam getting :

PHP Warning: include(/var/www/html/cacti/include/config.php): failed to open stream: Permission denied in /var/www/html/cacti/include/global.php on line 46
PHP Warning: include(): Failed opening '/var/www/html/cacti/include/config.php' for inclusion (include_path='.:/usr/share/pear:/usr/share/php') in /var/www/html/cacti/include/global.php on line 46
FATAL: Cannot connect to MySQL server on 'localhost'. Please make sure you have specified a valid MySQL database name in 'include/config.php'


all permission are cacti:cacti (user), and the database config is perfectly fine..

whe the hell ?:(

[daibosatsu]

It's not a good idea, but can you try a fresh install and run cacti as root - this mean root account not su? (still change owner of rra and logs and other files to http if need as instructed by manual)
then in crontab remove the sudo http part, as you're running as root.
Give it a try

PS Or try */5 * * * * {path to su} -u cacti /usr/bin/php /var/www/html/cacti/poller.php > /dev/null 2>&1

-u
The -u (user) option causes sudo to run the specified command as a user other than root. To specify a uid instead of a username, use #uid.

I thought I died installing cacti and one day till now it's working really fine with me =)
Now I think i'm in love

[paulgevers]

Check the permission of the rrd files. If you created them with root permissions, the crontab (you created one, right?) will not add new data. The files should be writable for the cacti user.

[filipn]

installed cacti obn another machine ( 8.8a with rrdtool 1.4 ) -> without fuc** problem. (all working like a charm)
My cacti on another machine (8.7i with rrdtool 1.2) -> NOT WORKING.

but EVERYTHING including cron/permission/database is identical.

wtf ?

The problem is I have to use the 8.7i -> prod environment, very hard to get new repo/update or whatever.

And you know... cron is not working on the 8.7i , I need to launch it everytime by hand..



this is madnesssss

f

[daibosatsu]

I think it's because of your permission. DId you apply any patch or try change run by root?

[filipn]

Guys, i mede it. So appreciate all your time and help for me !!

It almost works... when I display all available graphs for the host its perfect.. but when I click on one of them to see more details ( daily, weekdly .etc ) I get empty graphs.. but the graphs shown on the main screen are just perfect..

I am getting better with cacti - bu in evey step it make me sad, it can not jsut works ?




f

[daibosatsu]

just wait, it's the weekly summary/monthly so you have to run it for some day
glad you got it working
