Which process generates the rrd-files?

Deviloper · Post by **Deviloper** » Mon Aug 17, 2009 8:21 am

Hi there,

I got cacti 0.8.7 running on a Debian 5.02, Apache2, MySQL5, PHP 5.2.6.

I have this Problem:
###############################################
adding new graphs from within the webinterface I keep getting the errors:

Error: opening '/var/www/cacti-0.8.7e/rra/test-router_de_tmptotal_19824.rrd': No such file or directory

This "mostly" applies to rrd created via the WebGUI. RRDs greated from the commandline of (user cacti) using add_device and add_graphs works "mostly" fine. (See last post,,,)

So I thought it is a problem of the Web-Servers User-permissions.
I thought about adding the webserver user an additional group, the group auf the user cacti "cacti gid 1001".

I have no idea how to figure out the effective gid of the www-data apache2 processes... but don´t think that this is the problem because 777 the dirs and files don´t help.

Although I was not able to purge the log-files from the webgui, but changing /logs/cacti.log to cacti cacti to rw-r--rw- helps here...

cacti also owns the database "cacti7".

I use "new graphs" selecting the host test

+ Created graph: test - Temp. - VTT 1 outlet te
+ Created graph: test - Temp. - VTT 2 outlet te
+ Created graph: test - Temp. - VTT 3 outlet te
+ Created graph: test - Temp. - module 1 outlet
+ Created graph: test - Temp. - module 1 inlet
+ Created graph: test - Temp. - module 4 outlet

the graphs are not displayed all I see is a blank site with the graph titles.

The properties looks like that:
/usr/bin/rrdtool graph - \

After deleting the Graph Templates from the list of "Associated Graph Templates" for this host I am not able to add it again. It does not show up in the select box....

the same with "create graphs for this host".... the graph template is not listed, althought it is in the host-template of the device and data query looks good.

when I reapllie the host_template by cli with

php -q host_update_template.php --host-id=384 --host-template=10

I get:

Poller Item Cache:
The Script does not show up in the poller item cache.
Neither under host: any action: any nor host: any action:scriptserver ss_cisco_temp....

I guess this is the core of the problem....

Thats it don´t have any more debugging information...

Tell me how to fix this....

Can really nobody tell me the STEP (Process situation) in which the RRD should be created?

schurzi · Post by **schurzi** » Tue Aug 18, 2009 4:13 am

The RRD files should be created by the poller.
So the first poller run after you create a graph/datasource creates the rrd file.

Deviloper · Post by **Deviloper** » Tue Aug 18, 2009 4:32 am

Thanks so far.

But in this case the rrd-files are not created.

What does the poller check to notice that a rrd-files does not exit?

How can I use the poller on the cli to check manuelly for cinfiguration errors or errormessages that show up when it tries to set up an rrd file?

This also means it could take up to "n"-minutes until the rrd is created?

schurzi · Post by **schurzi** » Tue Aug 18, 2009 4:42 am

you can run the poller in debug mode:

Code: Select all

php /path/to/cacti/poller.php --debug

I gues the poller checks if the file exists, if it doesn't it will be created. Also make sure the user who runs the poller has permissions to write to your rrd directory.

Deviloper · Post by **Deviloper** » Tue Aug 18, 2009 4:51 am

Thanks!

Joop I check that. permissions should be no-problem here.

I figured out that normaly the rrd-files will be generated asychron, not directly. I thought that cmd.php will be triggered at the same moment I hit the button...

ok but still the files in my case are not created. So I wll turn on the --debug hope that this will give me a deeper look.

PS: Great fooder you have there.

Post by **TheWitness** » Tue Aug 18, 2009 6:51 am

Way too much information, but whatever.

1) The poller cache dictates what is polled
2) The poller.php launches cmd.php or spine to ask questions of devices
3) The cmd.php or spine write to poller_output table
4) poller.php empties poller_output, by first creating the rrdfile, if it does not exist, and then adding the values from the poller_output table to that rrdfile

There are a few things that can go wrong:

1) There is no entry in the poller cache for the item in question - Template Issue
2) There are entries but no RRDfiles - Either permissions, or problem with poller, or RRDtool crashing, or less likely Template issue

Diagnosis:

1) Run "php -q poller.php --force" as root. If you don't get Ok's, then RRDtool crash likely
2) If files suddenly appear in rra folder. Permissions.

Hope this helps, "a little".

Having same problem (rra not created) while trying to debug I change from spine to cmd.php in Settings/Poller and miracle, it works

coming back to spine my rra are not seen

nota : I use --graph-type=cg

Hi all,

I have the same problem like the other ones before me, but still see no RRDfiles. I am using cmd.php and e.g.

Code: Select all

php add_graphs.php --graph-type="cg" --graph-template-id=57 --host-id=105 --graph-title="abcdef"

as the command to add the graphs.
Debugging through the poller.php only shows... nothing... the graphs are not in the poller.php (except the graphs, I creating directly within cacti). Although, the graphs, which were created by cli, I find in the poller cache.

As Witness said, there must be an error in one of those:

2) There are entries but no RRDfiles - Either permissions, or problem with poller, or RRDtool crashing, or less likely Template issue

So I checked permissions --> permissions are ok (777)
problem with poller --> might there be a (general) problem, if the graphs created in cacti itself were polled correctly?
RRDTool crashing --> How may I check this? Same as with problem with poller: A problem, although the graphs in cacti are ok?
template issue --> I use the same templates for my cacti created graphs

crontab etc. is working fine, too.

Hope someone could help me

Please see 2nd link of my sig for debugging. I suspect downed host detection to be the root cause

Which process generates the rrd-files?
