## Configuration

### Grafana
The Config for the dashboard relies on the variables defined within the dashboard in Grafana.  When importing the dashboard, make sure to select your datasource. 

Dashboard Settings -> Variables

WAN - $WAN is a static variable defined so that a separate dashboard panel can be created for WAN interfaces stats.  Use a comma-separated list for multiple WAN interfaces.

LAN_Interfaces - $LAN_Interfaces uses a regex to remove any interfaces you don't want to be grouped as LAN. The filtering happens in the "Regex" field. I use a negative lookahead regex to match the interfaces I want excluded.  It should be pretty easy to understand what you need to do here. I have excluded igb0 (WAN) and igb2 (only used to host vlans).

After writing this up, I realize I need to change this variable name, it's just not going to happen right now. 

### Telegraf
[Telegraf Config](config/additional_config.conf)

In the [/config](config/additional_config.conf) directory you will find all of the additional telegraf config. In pfSense, under Services -> Teltegraf, at the bottom of the page with the teeny tiny text box is where you paste in the included config.

I also included the config for Unbound DNS and it's commented out.  I'm not currently using it, but it's fully functional, just uncomment if you want to use it.

### Plugins
[Plugins](plugins)

I put all my plugins in /usr/local/bin and set them to 555

To troubleshoot plugins, add the following lines to the agent block in /usr/local/etc/telegraf.conf and send a HUP to the telegraf pid.

    debug = true
    quiet = false
    logfile = "/var/log/telegraf/telegraf.log"
    
I also included a wrapper script for Unbound DNS.  I'm not currently using it, but it's fully functional.

### Running on

    Grafana 6.7.1
    Influxdb 1.7.10

[Original Reddit thread](https://www.reddit.com/r/PFSENSE/comments/fsss8r/additional_grafana_dashboard/ "Originial Reddit thread")

I was going to post this in the thread made by [/u/seb6596](https://www.reddit.com/u/seb6596 "/u/seb6596") since this is based on [their dashboard](https://www.reddit.com/r/PFSENSE/comments/fsf7f7/my_pfsense_monitor_dashboard_in_grafana/ "their dashboard"), but I made quite a few changes and wanted to include information that would get lost in the thread.

What I updated:

- Created dashboard wide variables to make the dashboard more portable and easily configurable. You shouldn't need to update any of the queries.
- Took some inspiration and panels [from this dashboard](https://grafana.com/grafana/dashboards/9806 "from this dashboard")
- Included gateway RTT from dpinger thanks to [this integration](https://forum.netgate.com/topic/142093/can-telegraf-package-gather-latency-packet-loss-information/3 "this integration")
- Used[ telegraf configs](https://www.reddit.com/r/pfBlockerNG/comments/bu0ms0/pfblockerngtelegrafinfluxdb_ip_block_list/ " telegraf configs") from this post by [/u/PeskyWarrior](https://www.reddit.com/u/PeskyWarrior "/u/PeskyWarrior")
- Tag, templating - No need to specify all cpus or interfaces in the graph queries. These values are pulled in with queries.
- Added chart to show all adapters, IP, MAC and Status[ from here](https://github.com/influxdata/telegraf/issues/3756#issuecomment-485606025 " from here")
- Added Temperature data based on feedback from[ /u/tko1982](https://www.reddit.com/u/tko1982 " /u/tko1982") - CPU Temp and any other ACPI device that reports temp is now collected and reported

### TODO

- Include IP and ping methods from [/u/seb6596](https://www.reddit.com/u/seb6596 "/u/seb6596") when they are back online.
- Make it pretty. I've never been good at this part
- Get the RTT calculations right from the dpinger integration. It's in microseconds but for some reason doesn't match the graphs in pfSense when I compare them.
- Fix the go plugin to show interface status (up/down) and subnet.
