• NEW: Notifications and integrations
• NEW: Changelog displayed when updating
• NEW: New-look WebUI page

Notifications and Integrations

Currently, supported mechanisms for notifications/integrations are:

• Email
• Discord webhook (https://support.discord.com/hc/en-us/articles/228383668-Intro-to-Webhooks)
• Pushover (https://pushover.net/)
• Custom actions (write your own scripts to do whatever you'd like)
• Healthcheck monitoring (https://healthchecks.io/)
• InfluxDB data export (if you already run InfluxDB, you can push connmon data to it and visualize it in Grafana, for example)

There are 4 events which trigger the notifications:

• On each ping test
• Ping threshold exceeded
• Jitter threshold exceeded
• Line Quality threshold exceeded

Email configuration

connmon v3.0.0 marks a move to a standalone email configuration that can be utilised by other scripts. If you have Diversion installed, connmon will detect this and migrate Diversion's config to the new standalone location with is /jffs/addons/amtm/mail

connmon will create links for Diversion to follow the configuration to the above location.

Really like the new-look WebUI. Pop ups and all. Also like the email integrations.

 

[pinkgrae]

Just upgraded to 3.0.0 - loving the new UI and email notifs - thanks @Jack Yaz!

 

[heysoundude]

Eagerly anticipating the new WebUI in spdMerlin...after you've enjoyed your hard-earned and well-deserved break

 

[JT Strickland]

COOL, man, Thanks!

 

[Adooni]

would be possible to add to connmon something like it line ping click to extend info like here https://support.8x8.com/cloud-phone...interpret-mtr-winmtr-ping-and-traceroute-tool

I was thinking about Traceroute that you would know that issue was between PC and our router, router and ISP modem etc. all steps until pined address. This would be very helpful even for ISP discussion as they always try to point that it is because we using our router

Connmon just stopped working. Pings are not working see attached. What do you need from me to debug this? I have vers 3.0.2 with no updates available.

Run a manual ping test, i suspect something wiped out the cron job

Run a manual ping test, i suspect something wiped out the cron job

Manual ping test gives no results. I did it yesterday when I 1st noticed the problem, then did it again this morning, both with the same no results. There is an entry in the cron table table for connmon. By way of comparison, ntpMerlin which also uses ping seems to be doing fine.

 

[Jack Yaz]

try a different IP? equally try manual ping:

ping 75.75.75.75

I think I found the problem. I was using 75.75.75.75, and it seems that has stopped responding. I tried doing pings from the Tools tab and that too did not show results. But if I used another location, 1.1.1.1, or google.com, all seems to be OK. So let's put this one into the category of Comcast's problem.

I think I found the problem. I was using 75.75.75.75, and it seems that has stopped responding.

Maybe because skynet seems to have been blocking outbound connections to 75.75.75.75 lately?

Where can I look to see if that is happening?

Update: Without me doing anything to my configuration including with Skynet, 75.75.75.75 is now working again, so I'm guessing it really was a Comcast problem that they fixed.

Getting this error when trying to install. Any clues why I wouldn't have Entware on my router?

Thanks

Entware doesn't come preinstalled on Asus routers. Most of us find that the most convenient way to install entware (as well as conmonn and a number of other scripts) is through amtm, which comes preinstalled on recent versions of asuswrt-merlin - see Entware · RMerl/asuswrt-merlin.ng Wiki · GitHub
