Trying to get graphs to a file

Votes:

0

I have a script that will call prtg to get a graph, how can i do this? I do not want to show the graph on a page, rather download it to a folder for further processing.

$url = "https://monitor.newcoit.com/chart.png?type=graph&width=900&height=420&graphid=1&id=2192&username=username&userhash=somehas"; echo "<img src='" . $url . "'>";

i am trying to use php file_get_contents or fopen() and when it try these, i get the login page for my prtg instance

api graphs php

Hello,

thank you very much for your KB-Post. Can you please try the URL first in a normal browser? Do you then get a graph image shown? Just to check, please use 'passhash' not 'userhash'. The latter does not work.

best regards.

the browser works fine.

i can also do echo "<img src='http......'>";

and that works fine too.

$url = "http://....."; the problem is with file_get_contents($url) or fopen($url). when i do these, it returns the login page....

That would be a problem in your script then. I'm sorry, but we can't assist with that.

so as far as you know, there are no limitations to the types of calls that request the graphs? browser type, curl options or anything?
