No graph after update 0.8.8 > 1.0.0 > 1.0.1

Hello,

After the cacti update the graphics are not displayed. I have copied them well into the rra/

In the logs I have no errors.

Look into the databse table "poller_item". There you find the "rrd_path". Ist this the correct path to your rrd files ?

[Philippe-M]

The access path is the right one

[cigamit]

Please goto Console -> Graphs edit the Graph in question. Then turn on 'Debug' mode. Past the output you receive from Debug mode. Also, please goto /etc/php.ini and edit the php.ini. Set error_log = /tmp/php_errors.txt and restart apache so we can catch things. They will be in your Cacti log in this release, but the error_log will be easier to search.

Retour de RRDTool :

ERROR: unknown option '--pango-markup'

I think the error does not come from the path but from the error rrdtool : ERROR: unknown option '--pango-markup'

# rrdtool -v
RRDtool 1.2.27  Copyright 1997-2008 by Tobias Oetiker <tobi@oetiker.ch>

[cigamit]

This issue is resolved now. You might want to consider upgrading RRDtool as I suspect many Graph Templates will start to incorporate --pango-markup attributes. For example, the Thold HRULES already do.

[browniebraun]

Jimmy, I was just writing my answer. ;)

[browniebraun]

Please take care of updating your RRDtool version under "Console->Configuration->Settings->Tab:General" appropriate to that new version you are going to install. (1.3.x or 1.4.x or 1.5.x or 1.6.x)

[Philippe-M]

But on my server i've :

# rrdtool -v
RRDtool 1.2.27  Copyright 1997-2008 by Tobias Oetiker <tobi@oetiker.ch>

With the old version of cacti it's ok.

[browniebraun]

Well, but if you are running into trouble again you should definitely take an upgrade into account as Cacti officially no longer supports that 9 year old version of RRDtool.

Regards -Andi

[cigamit]

The reason you still have this error is that you are using RRDtool 1.27, and you have selected from the GUI, that you are using RRDtool 1.3.x. It's an obvious mistake. Make the GUI change, and you are back in business.

[Philippe-M]

@cigamit : ok but the gui does not offer an older version of rrdtool that is why I left the oldest version available in the gui.

@browniebraun : ok, that's what I started doing, I'll have to migrate from rhel 5 to rhel 7. it was scheduled but not so soon. It would be necessary to change the documentation, in the prerequisites it is written that rrdtool 1.2.x is supported: http://docs.cacti.net/manual:088:1_installation#requirements

[cigamit]

Okay, I've added RRDtool 1.2.x back. Take a fresh pull from git, and you should be able to select it.

[Philippe-M]

it's ok in graph setting

not in graph tab

[cigamit]

On the graph tab, you will have to use either the browsers debug tools, or install something like firebug on Firefox. From either of these tools, find the Network panel, and inspect the reponse for the graph_json.php? call to the web server. Open it up, and see if there are any cacti errors in that output. Post what you find. Screen shot or otherwise.

[DavidLiedke]

I had the same issue with some graphs.

Google Chrome Developer Tools:

Preview Tab: preview-tab.txt

Response Tab: response-tab.txt

Is this that what you need ?

[cigamit]

Yea, that was enough. Can you do the same viewing of graphs, but this time keep the console tab open in the debug window and see if you are getting errors as the 'response.txt' is formatted correctly and includes and image. Also, let me know your browser and version and os and version of your browser.

[Philippe-M]

response.txt

Fedora 25, firefox 51.0.1 (64bits)

[cigamit]

The team had a discussion on this and the solution was to remove RRDtool 1.2 support. The graphing on the Graphs page is dependent on RRDtool 1.3+ features. So, we don't have much of a choice.
