Calculating Network Backbone Bandwidth Requirements

@dashrender ok. What tools do you use to find the current state of the network?
-
Any kind of bandwidth graphing tool coughZabbix*cough that will let you monitor the network switches for bandwidth, packet loss, and ping times.

So much effort to get that going again. . . didn't yourself or @JaredBusch write a guide on standing Zabbix up?

@JaredBusch wrote the easy to follow one.

No tools needed most of the time. Your backbone needs to be upgraded when the existing backbone is saturated to the point of impacting system performance. Human observation and the reporting from your existing switches will tell you that.

If you only have dumb backbone components, then it is just intuition.

Yeah, this is what I have relied upon mostly.
Had a location that had a broadcast storm whenever the doc was in the office. Turned out the NIC on his PC had failed and was bringing the network to its knees.

Not really that much effort. It's quick to setup and you can probably find an snmp template for your switches.

It's a Zabbix kind of day around here.

As a MSP, when you walk in and see unmanaged switches under desks, you kind of know what needs to happen.

Last week I was onsite and uncovered a 100 Mb switch. The bonus was the 20 year old print controller hooked to it.
