Graph Poller Times.

byrons · Post by **byrons** » Sun Feb 06, 2005 5:49 am

Hi all, if this has been done before, sorry, I couldn’t find it.

I take no responsibility for this ‘hack’. USE AT YOUR OWN RISK.

Open Poller.php

Find Line 171

Paste the code below.

Code: Select all

/* Graph Polling Times */
$time = fopen('scripts/pollertime.txt', 'w');
fwrite($time, round($end-$start,4));
fclose($time);

Next

Copy Pollertime.php into the scripts/ directory.

Data Input Method:

Click Add

Name: Cacti Poller Time
Type: Script/Command
String: <path_php_binary> -q <path_cacti>/scripts/pollertime.php <path_cacti>/scripts/pollertime.txt

Click Create

Add Output Fields

Click Add

Field [Output]: time
Friendly Name: seconds
Output Fields: checked

Create

Data Sources:

Click Add
Leave both on NONE
Click Create

Data Source Name: Cacti Poller Time
Data Input Method: Select Cacti Poller Time

Internal Data Source Name: time

Click Create and then click save

Graph Management:

Click Add
Leave both on NONE
Click Create

Title: Cacti Poller Time

Create

Graph Items:

Click Add

Data Source: select ‘No Host – Cacti Poller Time (time)
Colour: select one
Graph Item type: Area

Click Create

All done.

If anyone knows of a better way to do this, it would be good to see. Also, not sure of performance issues regarding adding code to poller.php.

Cheers
Byron

EDIT: Thanks to Phil a.k.a pvd for the graph template.

import it for 086d
go into the data input method and set YOUR paths up.
select a device (localhost)
add a specific graph

That's wierd, I thought it was a pretty useful graph. Only 14 downloads.

Anyway, thanks ihweb :p

Works swell. 'twould be sweller if it would show me that nice "fire effect" and (particularly) the last/average/max numbers, tho...

I suppose I could figure it out, but it looks like you already did, so I thought I could be lazy.

Thanks!

I borrowed the fired effect from this http://forums.cacti.net/about6039.html

Hi, this is real cool. I am not able to get this working, not sure if the placement of the code I paste to the poller.php is the issue, it would seem so, I get following errors when running the code manually:

PHP Warning: fopen(scripts/pollertime.txt): failed to open stream: No such file or directory in /var/www/html/cacti/poller.php on line 172
PHP Warning: fwrite(): supplied argument is not a valid stream resource in /var/www/html/cacti/poller.php on line 173
PHP Warning: fclose(): supplied argument is not a valid stream resource in /var/www/html/cacti/poller.php on line 174

but the pollertime.txt does exist...

running 0.8.6c

may be full path requied?
I add this in poller.php :

Code: Select all

$olddir=getcwd();
chdir('/usr/local/www/cacti/scripts');
$time = fopen('pollertime.txt', 'w'); 
fwrite($time, round($end-$start,4)); 
fclose($time);
chdir($olddir);

Other than I don't like it going into the scripts directory, this is quite cool. The power of Cacti and it's user group is awsome!

Works great. Is this something that will be build into the next cacti version. It would be a great addition for fault finding and to check the speed of the program.

Great work!

I had not considered this as the method. What we are going to do is save this information in the MySQL database and then create a template the pulls the information using a data input method call SQL Call or something like it. So, it is effectively the same thing.

Just liked the simplicity of the solution

Me too. It will continue to work in future versions.

I did apply the change you suggested and I'm not seeing the error
anymore when running the script manually. But the rrd and the graphs are still not being created..

help

$olddir=getcwd();
chdir('/usr/local/www/cacti/scripts');
$time = fopen('pollertime.txt', 'w');

fclose($time);
chdir($olddir);

Small tip - I needed to create the pollertime.txt file

cd ~cacti/scripts ( or whever it is )
touch pollertime.txt
chown cacti pollertime.txt

If you want to save yourself some typeing here is a graph template for pollertime.

import it for 086d
go into the data input method and set YOUR paths up.
select a device (localhost)
add a specific graph

Cacti

Graph Poller Times.

Graph Poller Times.
