Monitoring page - what creates the metrics for the "Quality" graphing category?
Still learning pfSense, and I've been struggling with some WAN service outages lately. I traced things to periodic radical increases in RTT. For instance, trace route to a destination (QuadNine DNS server at 22.214.171.124, some others that are 8 or so hops away) rises from < 100ms to > 2000ms, corresponding with the service outages.
I had been considering installing the mtr package to see if that had a graphing function but then I found the "Monitoring" page in the webGUI, and that graphing function's "Quality" graphing axis configuration. I was wondering what facilities in FreeBSD / pfSense were responsible for acquiring or generating the data that underlies that graph? I'd like to be able to share the data with my ISP.
Thanks for any help!

The quality graphs are using the data from dpinger: https://docs.netgate.com/pfsense/en/latest/book/routing/gateway-settings.html#probe-interval
@Grimson Thanks! The built-in help points to a URL that is basically broken, and there are two different blobs of documentation, that have different structures. Your link works:
But the equivalent one doesn't work in the "documentation" tree that isn't in the "book" (I get a 404):
If I do a "curl -I https://docs.netgate.com/pfsense/en/latest/book/" and a "curl -I https://docs.netgate.com/pfsense/en/latest/", the former says it was last modified March 6, while the latter has no modification date, but is out-of-date. I don't see the point in having the "pfSense Documentation" if it is out of date or inaccurate. I'll know to not read that in the future.
And could you tell me where you got the non-working link? The Book has a different structure then the documentation, so a link to the docu section concerning traffic monitoring would be these:
If there's something wrong with the documentation, there's a GIT for that (and to report errors or wrong links). Also one should note that documentation != book in content. And how do you specify the documentation is "out of date"? A simple click on "page history" shows the docus last commit at February 2nd 2019. So I somehow doubt it to be "out of date".
@JeGr Sorry for taking so long to reply.
Broken link came from navigating to the "Status" --> "Monitoring" page in my pfSense router, then clicking on the "?" icon in the top right of the page. That links to "https://192.168.1.1/help.php?page=status_monitoring.php", which seems to redirect to "http://docs.pfsense.org/index.php/No_Help_Found", which then redirects to "https://docs.netgate.com/pfsense/en/latest/index.html". I was expecting documentation about the "Monitoring" page. I guess I'm still just a n00b but I was expecting the redirect to something that actually pertained to the page I was looking at.
I don't know how the "documentation" and the "book" differ in the origin of their content. I erroneously thought they originated from the same place because their visual layout was / is nearly identical. I had to compare the URLs side-by-side to realize I was looking at a different body of documentation. We can consider this issue resolved.
