Good monitoring tool Ubuntu 12.04 + nginx + virt hosts
Hey guys, As the title mentions, I'm searching for an monitoring tool to watch my webtraffic on my virt. hosts websites. All websites are running on 1 Ubuntu 12.04VPS. I've searched around and found some options like cacti and nagios but I'm wondering if they support vhosts and if their memory comsumption is okay? Also I found ntopng which I love (<3) from the visiual display part but that one is not free? http://www.ntop.org/products/ntop/ also with ntop it tries to install apache2 when I use apt-get but I already have nginx installed so I don't want that. So guys, what would you guys advise me for an webserver 1VPS vhost nginx config on Ubuntu 12.04? Thanks!!
