Graphs Stop With Upgrade / No New Graphs

Oxygen · Post by **Oxygen** » Thu Nov 24, 2005 5:00 am

I just upgraded tonight from version C to version G of Cacti. After the upgrade, all of my graphs stopped working and now when I create new graphs, they just come up as Red X's on the page.

When I got to debug any of the new graphs, I get this error:

RRDTool Says:

ERROR: opening '/usr/share/cacti/rra/wsapp_srv_min_189.rrd': No such file or directory

The log file shows the following:

Your help is appreciated!

Happy Thanksgiving!!!

Did you copy over you rra files from the old installation?

Oxygen · Post by **Oxygen** » Thu Nov 24, 2005 2:11 pm

Yes, the graphs that were there from the previous installation are still there, they are just not graphing any more.

When I create a NEW graph, the error above is the one that I get.

Oxygen · Post by **Oxygen** » Thu Nov 24, 2005 2:29 pm

Here is a screen shot.

The graphs above were there from version C.

The graphs below are the new graphs I created after the upgrade to G.

It seems the scripts are not executeable under the cacti-0.8.6g source distribution:

[root@nms1 scripts]

.........Now that's better.

chmod 700 may be more secure....

Post by **rony** » Fri Nov 25, 2005 10:27 am

That shouldn't matter, the scripts are always called with there interperter, IE perl or php.

If the permission thing helped, then there might be a path issue under php.

Oxygen · Post by **Oxygen** » Fri Nov 25, 2005 1:02 pm

I have tried that, still no go. Getting errors like:

ERROR: opening '/usr/share/cacti/rra/wsapp_srv_min_189.rrd': No such file or directory

Cacti is running as ROOT.

Oxygen · Post by **Oxygen** » Sat Nov 26, 2005 3:24 am

Okay, I was reading the posts located here: http://forums.cacti.net/viewtopic.php?t=8583

So I downloaded all the files from here: http://www.cacti.net/downloads/patches/ ... e-patched/

Now I am not getting any more RRD errors, and the graphs do show up, but they are all blank! The existing and the new ones, they all show up with "nan" for values and do not graph anything.

It looks like the poller is running fine though:

Code: Select all

11/26/2005 03:20:26 AM - SYSTEM STATS: Time: 24.3706 s, Method: cmd.php, Processes: 1, Threads: N/A, Hosts: 13, Hosts/Process: 13  
11/26/2005 03:20:25 AM - CMDPHP: Poller[0] Time: 23.5095 s, Theads: N/A, Hosts: 12

But the data is not being written to the RRD files...

Please help. I love Cacti and it makes me upset when it does not work.

Post by **gandalf** » Sat Nov 26, 2005 7:35 am

Please have a look at the device list. Host in status down won't be polled. Have a look at the Downed Host Detection to change this.
If polling works, run one polling cycle with logging set to DEBUG. Look at cacti.log for failing scripts.
If this works, run the poller from command line as cactiuser or change your crontab to

Code: Select all

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

and have the output in poller.log. Look for rrdtool update errors.

Please post a complete DEBUG log run also, please run poller.php from a shell and post it's output.

Thanks,

TheWitness

p.s. If this is only affecting script's, there was a GLIBC update that was not behaving well in certain versions of Linux that may be affecting PHP's popen command.

Looks like the graphs are generated only when I run poller.php from shell. This only started working after I applied poller.php?rev=3333 per your directions.

So it looks like that the server is not executing the poller on it's own?

First, DEBUG log means
- (optional) clear cacti.log at <path_cacti>/log
- goto Settings -> Poller Logging Level and set this to DEBUG.
- run this at least for one polling cycle
- post the output in cacti.log from the last run (if you have cleared this before, simply post the whole file)
- reset logging level (do not fill all your disk space with logs)

Second, when poller won't run from crontab, this may be solved by providing the whole path to the php binary (e.g. /usr/bin/php instead of just php)
