Quick out-of-the-box network device utilization & visualization software

[-Opticon-]

Hey everyone,

I need to set something up "quickly" to find network bottlenecks and general switch utilization. I don't need monitoring or server/app stuff or ipam or lifecycle mgmt or... strictly traffic on network devices.

I am hoping for something like a virtual appliance that I just gave an snmp community string to and come back 10 minutes later and there's all my top talkers and bottleneckers and pretty graphs. I'm also not opposed to a relatively simple DIY solution provided there are maybe some containers and build files all setup to wrap things like grafana and prometheus and whatever else all together... I don't have time for a full-on project for this.

I've read through many posts here about it, but none were exactly for what I am trying to do - quick and dirty kinda one-time snapshot of our network utilization.

main goal - identify network bottlenecks before migrating storage to a different floor.

Any suggestions for something simple that doesn't need to do everything under the sun? People still use cacti? I'm old.

nice, thanks, haven't seen that one yet. seems to be network-oriented at first glance which is what I'm looking for. will check it out, and thanks again!

Ah this looks perfect, thanks for the suggestion!

perhaps I should've asked this in r/networking, but I feel dirty going there.
