2 Graph with same template didn't show the same (title & vertical scale)

[Rno]

Hello,
I create a template to display how many named process I got.

so here is the cacti/scripts:

Code: Select all

#!/usr/bin/env perl

delete @ENV{qw(PATH)};
$ENV{PATH} = '/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/sbin';

open(PROCESS, "ps ax | grep -v grep | grep -c $ARGV[0] |");
$output = <PROCESS>;
close(PROCESS);
chomp($output);
print $output;

When I call him in CLI it always show me 1 process even if none are running, like Perl doesn't do the 'grep -v grep' part. But that's not the current point.

Then I have source template who look like that:

unix_named_DS_template.png (30.28 KiB) Viewed 2191 times

Has for the graphe template it's looke like that:

unix_named_Graph_template-1.png (68.42 KiB) Viewed 2191 times

unix_named_Graph_template-2.png (44.83 KiB) Viewed 2191 times

But when I look a graph how i expecting to look like:

pool_mac_graph.png (194.96 KiB) Viewed 2191 times

And the latest graph I add it's not correct: Title and scale:

process_graph.png (123.38 KiB) Viewed 2191 times

And displaying the Graph debug mode doesn't show any difference, excpect for the title, it's look like that:

Code: Select all

/bin/rrdtool graph - \
--imgformat=PNG \
--start='-86400' \
--end='-60' \
--pango-markup  \
--title='Local Linux Machine -  pool_mac.php  - Process' \

--slope-mode \
--base=1000 \
--height=200 \

Any clue why is that ?
What I'm doing wrong ?

thanks for your input

Go to the Graph Templates page, select the Graph Template in question, and from the drop down, select Sync Graphs and press the Go button.

Hello,
NO luck it didn't change!

[TheWitness]

There must be a bug then. I'm a bit disappointed though. When you search by template from the Graph Management page, do you see both Graphs? One option would be to delete the old graph, save the RRDfile, create it anew, and then rename the old RRDfile to be the same as the new one.

[Rno]

The problem is not on old graph, it's on new graph.
But don't ask what I change, I'm remember messing arround with the title only.

As for a bug, I can't argue with that, but it will be odd to have one like that now!

Hmm interesting.

I select my 2 grpah who where having a bad name, and I chose the action 'reapply suggested name'
and, the first next popup give me the right name:

Code: Select all

Click 'Continue' to re-apply suggested naming to the following Graph(s).

    Local Linux Machine - findhost - Process
    Local Linux Machine - php - Process

Then when I click OK, the name appear correctly.
So one thnik resolved, then I have to find why the scale is not the same.

I try to make some trace to see where is the glitch, so far, nothing.

here is the step I did:
Click on create new graph for the Unix Named Process,
enter the name httpd as process, then click create:

This it the post seen on my browser

Code: Select all

{
	"c_0_109_122_113": "httpd",
	"host_template_id": "4",
	"host_id": "1",
	"save_component_new_graphs": "1",
	"selected_graphs_array": "a:1:{s:2:\"cg\";a:1:{i:109;a:1:{i:109;b:1;}}}",
	"action": "save",
	"__csrf_magic": "sid:044801c49736e3830406bf26d12981675f7fbedd,1696584126"
}

And on the popup:

Code: Select all

The Operation was successful. Details are below.

Created: Local Linux Machine - httpd - Process

So, so far the name of the process (as |input_process|) is correct.
The DS has the correct name:

Code: Select all

Local Linux Machine - httpd - Process

The graph name is wrong:

Code: Select all

Local Linux Machine - |input_process| - Process

the gprint on the graph is correct.

I was not able to dig through the 'html_graph_new_graphs' and 'html_graph_custom_data' to clearly understand what is going on.

The only way for me to fix the name issue it to do a 'reapply suggested name'
