Cacti

To have the same effect, I've added to '-Y' option (or --alt-y-grid) to the "$graph_opts .= " line in lib/rrd.php.

Maybe support for activating this option could be added for next releases ?

Yes it should work
I only tested with one slave...

Hi !

The rrd files are on the 'master' Cacti server (as well as the database).

Since boost uses its own custom poller, I don't think that it would work. Anyway, my hack should also improve the performance, since polling scripts can be distributed on several hosts

Update: It seems to work better if the slave pollers are the last ones to run... Still investigating... (add a sleep 60 in your slave cron jobs).

Hi ! Here's my simple modification to have a master / slave architecture. Just replace the original poller.php with the one below and: 1- install cacti on slave servers without the DB setup. Install the new poller.php also. 2- configure cacti to use the existing master mysql server. (and set-up mysq...

Hi ! My cacti is connected to an AD, and when users containing a dash are imported from the AD, I cannot modify them with "user management". To fix this problem, I had to add a dash in the validation RE in user_admin.php: $save["username"] = form_input_validate(get_request_var_po...
