Network Monitoring

[Swynol 375]

Wondering what people use to keep a eye on their equipment. I've started playing around with PRTG. only just installed it but so far its pretty decent. It uses sensors from the devices you add. so i added my server and it uses sensors from cpu, memory network card, disks etc which you can create graphs, tables and nice widgets to montior them. i have also added my router and switch and it can monitor the individual ports on the switch as well as throughput on each port.

 

i also have it monitoring ports on my NGINX so it knows when when emby, sonarr, nzb etc etc services are up.

Do you have a link to PRTG please ??

[Swynol 375]

ye sure its - https://www.paessler.com/prtg

 

100 sensors are free. i'm monitoring a few machines, one server, a few network devices and have used around 70 sensors.

This might be useful in figuring out my network issue.

Good job @@Swynol, I love PRTG have used it for a long time..  You can monitor individual applications too (emby, ffmpeg, nginx) as well as hardware.. Packet sniffing sensor lets you dig into your network traffic, or enable snmp on your router get about the same info.   Once you get some data captures under your belt it will alert you of abnormal patterns...    Yea its great when you have issues too, you can go back and look, compare stats from a year ago if you need to.. get text/push/email alerts based on your settings...   good to see more people using it!  Stats are fun!  

 

Fans, power supply, temperatures:

I installed it last night and only had a quick play with it, but it looks very comprehensive.

 

Need to let it run for some time to build the stats databases.

 

The mobile app is pretty good also.

how did you get the temp stats? are you using OHM and then a bat file?

[pir8radio 1292]

I'm using an HP server it has remote management iLO4  which outputs snmp info on all of the hardware.  They have like 40 temperature sensors in them...   But you should be able to get fan speeds and temps with OHM using WMI (if on windows).

[Swynol 375]

ah ok makes sense. just figured out how to use Open Hardware Monitor and a custom wmi. so managed to get cpu load and temp working across all cores.

You really should use rewrite rules, but i assume you would want access to prtg (all of it) remotely anyway?  Do you already have a PRTG.mydomain.com setup? Or do you only want to give access to the public map?   

[pir8radio 1292]

You can try this see if you can cheat, i didn't test, but it should allow the JS and whatnot to load I also removed the websocket stuff you can leave it in if you want:

Nginx might throw you an error with this though.. Let me know if not, ill show you how to do a rewrite that will work.

i mainly want to access the map but by keeping my key private so people only see the url i want them to see. i could have a separate rewrite to access the rest of prtg

thanks for the help. however i get the same error with that script.

Ok Ill see if there is a rewrite rule that will work for that..   Just curious why hide the key? You can change it/revoke it at any time, and it only allows access to that one map within prtg.

not really too bothered about hiding the key, only want it pointing to my domain name so that i dont have to remember the URL everytime i am away somewhere and want to check stats. Also i didnt know the key was linked to only one map which means i am less worried about the security of it.

 

Anyway that config you sent gets a bit further. i now get the 'loading' bar at the top of the page which i usually get just before the stats graphs load.

Using TeleGraf installed on pfSense to send data to InfluxDB, then using Grafana to display the graphs. There's more to that page (thats just a small portion of it) but I'm working on the rest still. I'll update when I have it finished.

Add another to the list of PRTG users, I use it both at home and extensively at work to monitor our nationwide sites.  It's a great tool!  Actually helped me to discover interference issues I was having at my old house with an ethernet over power connection I was running to my detached garage.  By looking at the times the interference was happening I was able to quickly determine it was being caused by the LED bulbs in my dusk till dawn lights lol weirdest thing I've ever troubleshot.

lol yea the PWM power supplies used in some of the LED bulbs put out quite a bit of EMI and harmonics on the line...  Yay PRTG!
