CACTI ADD NEW GRAPHS TIMEOUT / LAG FIX!

[pestilence]

One of the few (rather few) troubling issues of cacti was when trying to create New graphs for devices with a huge interface list (such as AS routers, BRAS routers etc).
My create new graphs page would stumble when trying to create new graphs for the specific devices, so i proceeded with a modification of the Add new graphs page.
The modified page (check attachement) will allow you to define a maximum number of interfaces per page, it will break them into several pages depending the Items polled.
This solved my lag / timeout problems when querying large devices.
NOTE:
To configure the maximum number of interfaces per page, enter the Settings --> Visual --> Rows Per Page (For New Graphs Screen) Section and configure it accordingly to your likes.

INSTALL:
To install download the attachement, there 2 files included the graphs_new.php replacement, and the include/config_settings.php Just unzip and copy them to the according directories and you should be ok.

TODO:
- Implement a cactid like poller for the re-poll functions of cacti, this would allow rapid re-polling instead of the timely php re-poll function.

If anyone is interested (and rather quick in writting C code, then drop a reply...).

Pestilence,

This patch needs some real work. To test, set your num_row... to 1 and see what happens with a situation where your have 2 data queries with more than just a few items. I used interfaces and disk partitions and it was way not happy. See if you can touch it up and then we can review again.

However, I would rather see a drop down with each of the data queries in the drop down and then if you select the interfaces dropdown item for example, you get xx pages. If you could make that happen instead, it would be much preferred.
