I am having issues getting this plugin to render graphs. All I am seeing is a broken image.

I have already checked the permissions on the /rra directory and they are okay (I even went the extra step and did the a+wx to make sure)

My apache logs are giving me this every time I attempt to use the plugin:

Code: Select all

Looking at those lines it is looking like a base_path issue but everything seems to check out (in reviewing my global.php).

Running 8.7b
Spine 8.7a
RHEL ES4 update 5 (64 bit)
AMD Opterons 64 bit

The following plugins are running correctly:

thold
monitor
reportit
weathermap

Ok, all of those watching. I have revised the authors plugin to provide some assistance. I have labeled it 0.3 for now. I am still awaiting feedback from the author. Here are the new features and bug fixes:

-bug: Make compatible with Windows.
-bug: Remove excessive Cacti logging where it should not be.
-bug: Make the poller_id more random to handle multiple users.
-bug: Remove table modification code that was not required.
-bug: Move RRDfiles to their own directory.
-feature: Make the default step "5" to keep all graphs compatible with one another.
-feature: Allow the designation of default timespan and update intervals.
-feature: Resize window based upon actual image size.
-feature: Allow altering of the display window timespan.
-feature: Add a cache directory setting.

Still to do are the following:

-feature: Allow to work with the boost plugin
-feature: Automatically clean the cache folder

If you ran the prior version, you might want to run the following command from the MySQL prompt:

Code: Select all

mysql cacti
ALTER TABLE `host` DROP COLUMN `myplugin`;
quit;

TheWitness,

Anything special we have to do to get this running on Windows? I installed your version (0.3) and it doesn't even look like the poller runs.

Thanks.

You have to goto Settings->Misc and setup the cache directory and then the Web Site account (typically 'apache') will need rwx access. As with other plugins, you need to grant yourself access first. What happens when you click the link under graphs?

[NetAdmin]

I did all those steps.. Even gave everyone full access to the cache directory, but there aren't any rrd files being placed in that directory. I don't think the poller is even running, as I should see the process running on the server, like I do when the 5 min poller runs.

[NetAdmin]

Interestingly enough, if I use the graph_image_rt.php and graph_popup_rt.php from version 0.2, I can at least see that the .rrd file is being created. Still displaying a red X, but certainly getting a lot farther than the version 0.3 files.

I had that problem as well (windows) look for the url string /plugin/realtime/

I think I had to remove an extra backslash, I think you'll find its trying to load the image http://plugin/realtime/xxx


After I fixed that problem I still couldn't get any data showing, only a blank graph.

[B-rad]

Ok, it does work after fixing the url

Great plugin

[NetAdmin]

Thanks B-rad! That was exactly the problem.

Removing the backslash in front of

Code: Select all

plugins/realtime/graph_image_rt.php?

in the graph_popup_rt.php file.

Hi everybody!

I'm using the TheWitness' version of the Realtime Plugin and I'm still having the following errors on Apache's error_log file:

[/size]
(I gave full permission in the "cache" dir for the Apache's user...)

What am I doing wrong?!

Thanks in advance!
(And sorry for my poor English...)

Hi all,

This plugin is really good idea in my opinion.
I installed it (one posted by TheWitness) unfortunately it does not work porperly.

After some debugging I noticed that two database queries (graph_image_rt.php:135 and graph_image_rt.php:162) do not return proper values.
Variable used in them ($local_graph_id) has correct value so it might be query which is wrong.

It would be great if you could take a look into this.

I am using cacti 0.8.7b under Ubuntu.
Please let me know if you need any more specific information.

Regards
Jacek

This plugin is really good idea in my opinion.

Second that, great idea. especially for the big NOC-style screen.

[TheWitness]

I'll do another whack at this shortly. I am going to make the graph generation work with Ajax instead of page refreshes and attempt to capture some of the anomalies in the plugin. Not too much work. I like this plugins very much. Thanks to the author.
