@VictorRobellini Totally understand and thanks for the heads up.

Any idea why I would be getting the following when trying the telegraf_gateways.py option?
[inputs.exec] Error in plugin: exec: fork/exec /usr/local/bin/telegraf_gateways.py: no such file or directory for command '/usr/local/bin/telegraf_gateways.py'
I'm having the same issues, what did you do to fix this?
I am using the fastjack version from here https://gist.github.com/fastjack/a0feb792a9655da7aa3e2a7a1d9f812f

Thank you very much for your work.
I had to install Grafana & Influxdb on Windows 2019. :|
Everything is working fine except Active users / Uptime / Interface Summary. It says no data.
I downloaded the files directly on Pfsense.
The data is being populated on Influxdb, though I could not make the telegraf.log to work.
Any idea on what am I missing?
Thank you.

If you are seeing the "Active users / Uptime / Interface Summary" in the influx DB but not on the graph, it's possible that there's an issue with the query and I don't think the telegraf.log is going to help. It could be a result of a bad dashboard import or a newer versions of Grafana.
You will want to specifically see what gets returned by the below queries:
select * from system limit 5 select * from net limit 5 -
@VictorRobellini Thank you very much for the fast reply. I agree that it could be relative to a bad dashboard import.
For the uptime panel I was able to import it from another dashboard and compared to yours and it was the same but the imported one was working.
I was able to fix interface summary by importing directly from the Grafana website and copy/paste the panel.
Active users was not working either on the other dashboard I imported.
These gives data but I did not had time to format it.
select * from system limit 5
select * from net limit 5Thank you again.

after copying the file to this folder, did you chmod +x it?

For the unbound - on telegrah - looks like does not work with the latest version of pfsense and telegrah
It used to work..
In telegraf config..
[[inputs.unbound]]
server = "127.0.0.1:953"
binary = "/usr/local/bin/telegraf_unbound.sh"Command to check:
/usr/local/bin/telegraf -config=/usr/local/etc/telegraf.conf --test --input-filter unbound
Output:
2020-11-18T00:31:41Z I! Starting Telegraf 1.13.4
2020-11-18T00:31:45Z E! [inputs.unbound] Error in plugin: error gathering metrics: error running unbound-control: Command timed out. (/usr/local/bin/telegraf_unbound.sh [-s 127.0.0.1@953 stats_noreset])

Recently tried out the new version of PfBlockerNG 3.0.0_1 and was looking to test the new python integration with unbound that produces the client ip in the logs when using null blocking. (requires pfsense 2.5.x and latest version of unbound)
Wanted to confirm that not only does it work but everything still shows up in this grafana dashboard.

@erbalo I am facing this similar issue, when I see the telegraf log I have this message everywhere... Did you find any solution?
For example:
-
This dashboard is absolutely fantastic! it works very well.
It looks like it would have taken a lot of hard work, time and effort.
Thanks for doing this! -
Any idea how to install Telegraf on SG-3100? pFsense version 2.4.5-RELEASE-p1 (arm).

To calculate the monthly WAN download/upload, use the following query format
SELECT non_negative_difference(last("bytes_recv")) FROM "net" WHERE ("host" =~ /^$Host$/ AND "interface" =~ /^$WAN$/) AND $timeFilter GROUP BY time($__interval) fill(null)
Set Query Options / Relative Time to - 'now/M'. Leave Everything else as is in Query Options.
For Visualization use 'Stat'. Then under 'Display' select Calculations > Total
Then Goto Field from the TAB above / Units > bytes(SI)

Bamm! thank you, this works now for me!!! Can someone maybe upload a fully working dashboard so we can use import in grafana? With a corected Mb/s etc..

Getting Mbps on the graph is easy.
Select the WAN Panel > Edit > Panel Settings > Axis / Left Y - Change this to bits/sec
Also change the query to add *8So your query will look like this
SELECT derivative(mean("bytes_recv"), 1s) *8 FROM "net" WHERE ("host" =~ /^$Host$/ AND "interface" =~ /^$WAN$/) AND $timeFilter GROUP BY time($__interval) fill(null)
Do the same for the LAN Panel (the first one). Then click 'LAN Interfaces' (the master container for all LAN panels - see pic) . Click Settings > Repeat for Datasouce and this Mbps setting applies to all LAN panels.

Thank you, for th WAN it is now correct just i am seeing there Mb/s - Megabit per second.
But for the LAN i need to see MB/s = Megabyte per second. I mean i need to see the exact value such as when you copy a file from your NAS, you see there the rate MB/s. -

I noticed recently that the systems row is no longer tracking the time range that is selected up at the top right.
Is this something that should be defined in the query or did something break with an upgrade somewhere along the way?
Can someone else confirm if they are able to see changes in the systems row statistics whenever the change the time frame in the upper right hand corner of the dashboard?
I did go ahead and pull down the latest json from github just to be sure that wasn't the problem.

@bigjohns97 Seems to be working for me.

@ab5g I did recently upgrade pretty much everything (pfsense 12, pfblockerng 3.007 grafana. Etc)
Just a heads up. I haven't had a chance to dig into the data to see if the dates aren't being kept or what really has changed.

@bigjohns97 I am on 11.3 with pfBlockerng at 3.0.0_7. If you recently updated to 12, make sure that the Telegraf additional configs are in place and your scripts are still in usr/local/bin with the correct permissions.
