defunkt uses a fool tools for his network

Loved episode 364. I work for a school and have found all of these tools an absolute necessity.

We have a TON of linux implemented in the rack, classroom, and elsewhere.

I would like to mention a few other tools we use.

Munin - Server stat monitoring (Windows/Linux) Requires a client but collects good information (and much easier to install and setup than Nagios's client monitoring). Zoom in on rrd graphs, etc. Custom graphs can easily be created with your choice of scripting language. Records data to RRD's (important later)

NTOP - A sniffing program to analyze traffic. We use this against our internet connection to identify the type of traffic being used on our network. We have other tools but this has proven to be VERY useful. Records all of this information to tons of RRD's. (useful later)

Observium - A opensource trending program that works with tons of equipment out of the box. It trends all kinds of information (also stored data in RRD's).

We were hit with DDOS attacks and decided we needed an "always-up dashboard" with an alarm to notify us when we were being hit. So we grabbed all of our RRD's and threw them into graphite and grafana to create: https://drive.google.com/file/d/1O6vo3t0REUZ8Aw1SHcuJVVEbEZvdDu18/view?usp=sharing

We threw a raspberry pi on the back of a 48 inch display, threw it on the wall with grafana. it updates as fast as the RRD's do, and even alarms when we set certain triggers.

The biggest decision was the audible alarm...
