Bonsai: An other cool zoom/history feature for Cacti

[Bisonlux]

Hi everybody,

I developed a similar Zoom/History function like the famous Cactistoric developed by Bruno Prigent (Bravo Bruno c’est du bon boulot!).
You can read the README file below and see a screenshot of the zoom function.
Two versions are available, the first for cacti-0.8.4 (bonsai-0.2-084.tar.gz) and the second for cacti-0.8.5 (bonsai-0.2-085.tar.gz).

Don’t hesitate to give me a feedback…

Bonsai README File

ABOUT:

Bonsai is very similar to Cactistoric developed by Bruno Prigent, with a little bit more user friendly interface in mind (my opinion).

Select in the graph (with your mouse) an area you are interested in. It's magic... the selected time period is displayed in a new graph.

You can also add the displayed graph to your favorites in your browser.

REQUIREMENTS:

Unix-based operating system
Cacti-0.8.5

Bonsai has been successfully tested with the following components

Redhat: 9 (Linux 2.4.20-8)
Cacti: 0.8.5
rrdtool: 1.0.40, 1.0.46
apache: 2.0.45
php: 4.3.1
IE: 6.0

Please share the experience you make with other systems and components: eric.steffen@gmx.net


INSTALLATION:

tar -zxf bonsai-0.2-xxx.tar.gz -C <path to your cacti directory>
cd <path to your cacti directory>/bonsai-0.2-xxx
./install.sh

Done!

NOTE:

As Cactistoric don't forget do change the number of rows in your rra. (Recreate your rrd files or use the rrd tune command).

I suspect your problem is being caused by cactistoric. The patch files are expecting unmodified versions of the files they are for. You probably need to get back to clean version of cacti and re-apply the patches for bonsai.

So, I must change my question at this time:
Can bonsai works with cactistoric?
Or
Can Bonsai show past data with 5 min. average? Like 2 months past?

Found another small problem with graph preview mode. graph_view.php needs to be modified to pass an end_time to graph.php.

Line 259 of graph_view.php
$now = time();
foreach ($graphs as $graph) {
print "<td align='center' width='" . (98 / read_graph_config_option("num_columns")) . "%'><a href='graph.php?rra_id=all&local_graph_id=" . $graph["local_graph_id"] . "'><img src='graph_image.php?local_graph_id=" . $graph["local_graph_id"] . "&rra_id=" . (empty($set_rra_id) ? read_graph_config_option("default_rra_id") : $set_rra_id) . "&graph_start=-" . (empty($set_rra_id) ? read_graph_config_option("timespan") : "0") . "&graph_end=" . $now . "&graph_height=" . read_graph_config_option("default_height") . "&graph_width=" . read_graph_config_option("default_width") . "&graph_nolegend=true' border='0' alt='" . $graph["title_cache"] . "'></a></td>\n";

Great job.

you can do..
just look at the patch file and apply the changes manually

its not simple but you can do it

Hello,

The mean reason I based the development on a fresh installed version of Cacti and not on Cactistoric is simple. Bonsai should be independent of other add-ons to be very easy to install.

Let’s take an example (in case of Bonsai is dependant of Cactistoric):
Someone wants to use the Bonsai’s zoom function. First of all he must install Cacti (ok normal), after that Cactistoric and at least Bonsai. So if something goes wrong it’s more difficult for him to find the problem. Imagine the complexity if you have a lot of add-ons …

So my question is (it’s for you PHP Expert), is it possible to have plug-ins (like Photoshop plug-ins) or something similar that allow you to install the feature you want. What are the best practices in developing PHP pages to simplify the integration of add-ons?

Here a link to understand the patch files (output of diff --context command)http://es-sun2.fernuni-hagen.de/cgi-bin ... %20Context for the people who have courage to modify it manually


Bonsai or Cactistoric give you the possibility to select and show graphs in the past, nothing else. If you want to display values with an average of 5 minutes and 2 month ago then the rrd file must contains these values (Rows). In your case, you have 1 sample in 5 minutes and you want an average of 5 minutes. So Step = 1. One day have 24*60=1440 minutes. So for 1 day you must store 1440/5=288 Steps and for 2 month 288*30*2=17280 Steps. So Rows = 17280.

An other example: You have an rrd files with 2 rra archives. The first represent 1 day with an average of 5 minutes (Step=1, Rows=288). The second represent 1 month with an average of 1 day (Step=288, Rows=30).

If you display a graph that shows the last 24 hours, it takes the first rra with 5 minutes average.

If you display a graph that shows 3 days ago, it takes the second rra (because the information are lost in the first rra) and take an average of 1 day.


Thank you to people who reports some bugs…

Bug:
Warning: Undefined variable: rra in /cacti-0.8.5/zoom.php line 64
fixed by adding this code in file zoom.php before line 46

Code: Select all

$rras = get_associated_rras($_GET["local_graph_id"]);
foreach ( $rras as $q )
{
    if ( $q["id"] == $_GET["rra_id"] )
    {
        $rra = $q;
        break;
    }
}

I don't now is it right but for me it works

Problem with Graph tree view, Single Pane mode:

you need to change line 561 in file lib/tree_view.php

Code: Select all

$now = time();
print "<td><a href='graph.php?local_graph_id=$local_graph_id&rra_id=all'><img align='middle' alt='$graph_title'

I just installed bonsai-0.3-085 (I have cacti 0.8.5) and when I click on zoom I can´t see the graph (neither can I select the zone in the previous graph) and get the error:
Notice: Undefined variable: local_graph_id in /var/www/html/cacti-0.8.5/zoom.php on line 90
Can you help me? Do you need any further information?

[Bisonlux]

Try this ...

In zoom.php file replace at line 90:

Code: Select all

where graph_templates_graph.local_graph_id=" . $local_graph_id);

with

Code: Select all

where graph_templates_graph.local_graph_id=" . $_GET["local_graph_id"]);
