Nan values in CPU and Memory graph

magzz69 · Post by **magzz69** » Mon Jul 28, 2008 3:19 am

Hello

I have install cacti and I can do a lot of graphs, but! The graph CPU Usage and memory usage doesn't work there are the famous NAN values.

When I put the debug mode RRDTOOL says OK!

SO I don't see where is the problem!!

Please help me, cacti is on a windows 2000.

Thanks a lot

1) ** README BEFORE POSTING ** Sticky

2) post verbose queries of each broken script.

Yes, I already see this page thanks!

But I use Windows so in the command prompt I can't do this for exemple :
chown cactiuser:cactiuser *.rrd

It told me that chown is not reconize.

I'm interested by the point 6 because my rrd files are automatically created but for some graph there is NAN values...

chown is a UNIX/Linux command. My guess is that you can't read English very well as BSOD2600 does Windows and not UNIX/Linux. Sorry, I just needed to jab something this morning. Don't take any offense to it.

Set logging to Medium. Review your Log. Make sure that the user the performs the polling has permissions to update the RRDfiles, not just read them. If the log provides good values and the RRD's are not being updated, then it's a permissions problem. Giving "Everyone" RW access to the RRDfiles, may du that for you.

How can I see if my log are good? in the cacti.log file?

I've already put files and folder to everyone read and write

Set log level to MEDIUM and review Cacti Log output after a poller run. If you get good output, then your problem is a permissions problem.

In cacti log I have that after a poller run :

07/28/2008 03:29:56 PM - POLLER: Poller[0] NOTE: Poller Int: '300', Scheduled Task Int: '300', Time Since Last: '176', Max Runtime '298', Poller Runs: '1'
07/28/2008 03:29:56 PM - POLLER: Poller[0] NOTE: Scheduled Task is configured to run too often! The Poller Interval is '300' seconds, with a minimum Scheduled Task period of '300' seconds, but only 176 seconds have passed since the poller last ran.
07/28/2008 03:30:00 PM - POLLER: Poller[0] NOTE: Poller Int: '300', Scheduled Task Int: '300', Time Since Last: '180', Max Runtime '298', Poller Runs: '1'
07/28/2008 03:30:00 PM - POLLER: Poller[0] NOTE: Scheduled Task is configured to run too often! The Poller Interval is '300' seconds, with a minimum Scheduled Task period of '300' seconds, but only 180 seconds have passed since the poller last ran.

How often are you polling? If not every 5 minutes, it may never run. Can you instead run "php -q poller.php --force" it may be "-f", or "-force" though...

Hi!

So when I put the command php -q poller.php --force its told me "could not input file : poller.php"

But I have the everyone's rights of total control activate on the file poller.php .

I running poller.php every 4 minutes thanks to a planned task in windows.

Every 4 minutes is not a good poller interval. Make 5 minutes. Also, please verify the location of the poller.php file. Then, here are your testing criteria:

1) login as scheduled task user
2) cd to <path_cacti>
3) run "php -q poller.php -force"
4) look for many oks
5) cd rra
6) verify RRDfiles have good date

Alright so it found one cpu, is that correct for your system?

Did you click on the 'create graphs' in the top right corner, select the cpu and then create? Waited 10 min before trying to look at the graphs?

Hi!

Yes I wait for graph building, but the others graph are good but cpu usage graph and memory usage don't.

I give you a screen of debug mode of my graph... If it can help
