Good day,

Hoping someone can guide me. I am a complete n00bie,i thing my needs are fairly basic but don't seem to be able to figure out how to doing.

I have 4 Netgear 48 port PoE switched and a TZ350 sonicwall. I would like to be able to monitor the following on each of these devices.

Immediate needs
Switch
1- the bandwidth on each ports and if it goes over 50% to alert me
2- is switch does offline
3- if one of the ports goes offline
Sonicwall
1- Internet speed, receive an alert if speed is over 50%
2- ping a remote site

In the future
1- monitor Hyper-V host and guest
2- monitor the speed of the nic on all workstation
3- monitor toner on HP laset printer

any help and guldens is greatly appreciated.

Thanks
Rudy

Moved to Help and Support; you'd posted this in a testimonials forum, so no replies.

Key thing for this is knowing, do your switches support SNMP? If yes, you can use MRTG, which will be included in NEMS Linux 1.6, or you can set it up on earlier versions (but easiest to wait for official support).

MRTG is the Multi Router Traffic Grapher, which is exactly what you're looking for for #1.

The rest (ping, online / offline, etc) are various check command respectively. check_ping, check_snmp, etc.

If you're brand new to NEMS (and Nagios) it'd be good to go through the initial tutorials first... watch the video(s), go through the ODROID Magazine exercises, etc. You'll find a lot of resources on the News section of the NEMS site. Let me know if you get hung up. Best to jump on the Discord server too, for community support.

Have fun!
