Get the graph url

[Amaranth]

I am currently using Zabbix 2.0 to monitor some machines. My hosts have graphs.

I am in the process of creating a Python script in order to download the images of specific graphs to include them into a report. I have the host name and the graph name.

I am not there yet, I currently only did the login, but I intend to get the host from it's name, go through the graph and find the right graph.

Once I have that graph, is there a way to get the url of the image that is produced in the preview tab of the graph configuration page?

I don't want to generate the url manually with the graph attributes since the image url has over 1700 characters (many items in it).

I was able to find the graph. I added permissions to the guest account to be able to read some info and i'm able to access the graph in the browser without login with an url like this:

url = serverAdd + 'zabbix/chart2.php?' + 'graphid=' + graphid

However, when I try to dowload the graph

graphImage = urllib2.urlopen(graphUrl)
...

I get an error:
urllib2.URLError: <urlopen error [Errno 11004] getaddrinfo failed>

Finally, I was able to work around the issue, but I was wondering if there was a better way.

# DOWNLOADS and SAVES the graph image
r=requests.post(graphUrl)

# SAVES the graph image
file = open(hostname + " - " + searchedGraph + ".png", "wb")
file.write(r.content)
file.close()
