Telgraf, Influxdb, and Grafana

[TravelMore]

Hello everyone,
I have searched a lot of different articles and vids on this topic of importing data from PFsense, into Influxdb, and to Grafana. I need help getting things setup.

I have PF sense & NTopng setup but it isnt as granular as i'd like so I wanted to setup something to make it more granular using grafana (specifically every device on my network and how much data it pulls per day, w/in given time frames, etc.) I really like the graphics of ntopng but its still confusing a bit for me in general. I need it to be more simple and specific which is why i wanted to try to configure something in Grafana.

I have pf sense setup to do remote logging as well and I have Telegraf installed.
My impression is that remote logging, telegraf, and ntop ng, all gather the same info just different ways to gather the info.

I have influxdb and grafana installed on a windows 10 PC. specifically because I dont use linux on a regular basis and wanted something im familiar with.
Telegraf is configured in PFsense and I believe NTopng is set to push data to influxdb and has that configured (for the most part).

Either way what i am having issues with is getting either Telegraf to talk to influx and then into grafana and or ntop ng talking to influx, and then into grafana.
I am not sure how to set either (telegraf/ntop into influx & grafana) of them up and I did come across one article that mentioned I have to setup a firewall rule to allow influxdb and grafana ports. I have not done that because I've only seen that mentioned once in all the research I've done AND I am not sure how honestly (im rather new to pfsense too). I know there are a few other plugins like Telegraf such as Netflow and maybe another one but I am not sure about the difference between all of them so I just stuck w/NTopng until i realized that its not as granular as what i want/need.

In all the research i did, i came across inputting the server ip (i think in influxdb) which I think is just the ip of my pc w/the port# at the end. I wasnt sure how to change that ip for influx or grafana and was curious how I could change that if I wanted to down the road.

Thanks in advance. Any help is appreciated. Sorry if anything is unclear I can try to re-explain something if needed.
