I'm by no means an expert on debugging problems, but could you provide a little more info?? Like the DEBUG output from the poller? Can you run a snmpwalk from the command line? Versions of everything, which poller are you running?

My questions are:

Has the poller ran at least one time?

Does the web server have access to the rra files?

Do you have php safe_mode enabled?

Do you have SELinux enabled and enforced?

Next approach: perhaps the rrdtool graph statement fails. Click on one of the graphs and select a wrench to see the statement. Copy this to cli and run. Post any errors.

I am seeing the same thing ... below is the output from the wrench:




/usr/local/bin/rrdtool graph - \
--imgformat=PNG \
--start=-604800 \
--end=-1800 \
--title="Test XP Host - Available Disk Space" \
--rigid \
--base=1024 \
--height=120 \
--width=500 \
--alt-autoscale-max \
--lower-limit=0 \
--vertical-label="bytes" \
--slope-mode \
DEF:a="/var/www/html/cacti/rra/test_xp_host_hdd_total_20.rrd":hdd_total:AVERAGE \
DEF:b="/var/www/html/cacti/rra/test_xp_host_hdd_total_20.rrd":hdd_used:AVERAGE \
AREA:a#002A97:"Total" \
GPRINTLAST:"Current\:%8.2lf %s" \
GPRINTAVERAGE:"Average\:%8.2lf %s" \
GPRINTMAX:"Maximum\:%8.2lf %s\n" \
AREA:b#F51D30:"Used" \
GPRINTLAST:" Current\:%8.2lf %s" \
GPRINTAVERAGE:"Average\:%8.2lf %s" \
GPRINTMAX:"Maximum\:%8.2lf %s\n"

I ran the poller manually to be sure there were files -- there are, and they are all owned by the cacti user.

Confused!

Thanks!

Well, I am now seeing the graphs ... apparently it really needed to run from cron, or I was being impatient. However, I do not see any data! For example, I am polling a machine with VERY little disk space, and I should see a graph representing that (I would think.)

Am I just being impatient? Or (more likely) am I doing something wrong?

Thanks!

Are the rrd files updated? Run rrdtool fetch <file> AVERAGE against one to see the last values.
Set Logging Level to DEBUG, search the log file for rrdtool update statements, copy one to cli and run to see any potential problems ....
Change crontab to read

Code: Select all

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

So you'll always have to last log from the poller to look for any rrdtool errors or the like

I think I found the problem, but I'm a bit confused as to what is going on. It appears that cron thinks that 'cactiuser' is a program to run, rather than a user to execute the command. I checked my syntax and white space, and I'm not sure what is wrong. This is in the system-wide crontab ... should I create the cron entry in cactiuser's crontab instead?

Thanks!

That depends on your likings. Please post at least a snipped of the crontab for help

I have the same problem and running the poller.php manually the graphs appeared. The line on the crontab looks like this:

*/5 * * * * cacti /www/php/bin/php /www/htdocs/cacti/poller.php > /dev/null 2>&1

(I changed cactiuser for cacti in all the installation)

The crontab was created for root user, but I don't know now why it's not running automatically.

Any suggestions?

Log has these lines:

But if I look under settings -> poller -> general it is enabled.[/img]

I have found that the manual posted in documentation has an error. On the crontab file you just have to use this:

*/5 * * * * /www/php/bin/php /www/htdocs/cacti/poller.php >/dev/null 2>&1

without the root.
