Partial patch to add all graphs support.

[akschu]

Zabbix Devs,

I find it very useful to see more than one graph at a time so I went to go create a patch that would add 'All' to the graph drop down which would allow you to view all of the graphs for a host. While I thought this would be real simple, the form validation kept getting in the way because it converts $_REQUEST["graphid"] to zero whenever an invalid graphid is used. Furthermore, graphid 0 seems to be the default and thus is already used by the app.

To work around the validation I used graphid 0.1 as the graphid for displaying all of the graphs, but that foces me to use $_GET instead of $_REQUEST in one part of the app. Now this shouldn't cause a security problem because it is never used in a SQL query, it is still a hack.

Anyway, can someone look at my patch and tell me what the zabbix way of doing this is?

I used this patch when I was running an older version of Zabbix server and it really helped me to get a quick complete view over the entire host.
At the moment I need to make a screen for every host to get the same kind of result and with a lot of hosts it is very time consuming.

And again I have the same question. Alexei, would it be possible to implement that functionality in future release of Zabbix?

i think it should be cool to be able to create something like 'screen template' so it won't be needed to create screens for ever host separately. but this 'all graphs' idea looks fine too.

It is already implemented in pre-1.6.
