App Error / Status Page

@nebulon said in App Error / Status Page:

Not sure if uptime kuma can be scripted that way to extract health and runState from the json result.

It appears to me that neither JSON key matching nor Regex are implemented yet, but there are open issues for both.

I was just taking the advice from @JLX89 because I felt that checking for runState might not be enough. But could you please explain the check behind health=healthy?

I've had it setup using the following and it seems to have been working, if the app goes offline it is reflected in Uptime Kuma.

Monitor Type: HTTPS(s) - Keyword
URL: Cloudron API URL
Keyword: healthy
HTTP Options - Method: "GET"

I'm assuming you could probably pull either of the following based on the Cloudron API documentation: "runState": "running" or "health": "healthy"?

This at least seems to be working for me -- but could be a better way of doing this. The obvious downfall is if you're tracking uptime rather than just status if you make config changes or need to restart the app this is reflected -- so we bumped up the heartbeat retry levels.

Revisiting this thread... Is a custom error page a planned feature? Or is it already possible and I just missed it?

@nichu42
If you want to hack around.

️ Notice: totally unofficial!

The files are here /home/yellowtent/box/dashboard/dist/

appstatus.html
notfound.html

You could hack a custom HTML in there, replacing the files (make a backup of the original files), which just redirects to, lets say, an uptime kuma or something else.

Have fun

I guess https://docs.cloudron.io/branding/#custom-pages

Excellent, thanks!

BrutalBirdie

@girish OH! I missed that doc. So it is official

nichu42

Ooops, I think it's the second time I have started a thread that could have been answered with a short RTFM. I'm glad that @girish is way too polite.
Thanks, I have set up the custom pages. Works perfectly. Now I can redirect visitors to my (externally hosted) uptime kuma status page when an app is not ressponding.

@nichu42 would you mind letting us know what you implemented and how as the final solution description?

@robi
Is there any specific you'd like to know?
I just did as mentioned in the doc:

Created a new directory /home/yellowtent/boxdata/custom_pages
Created two html files app_not_responding.html and notfound.html with nano and pasted in the HTML code that I had prepared on my computer
Saved and voilà

The HTML files contained an explanation of what went wrong and a link to my already existing uptime kuma status page, where I put a note to users if there is a longer downtime (planned or unplanned). I have uptime kuma running on a separate VPS so it does not depend on Cloudron to be working. I am checking for health via API as suggested earlier in this thread. You can see the result here: https://status.42bit.io

@nichu42 Yes, that's excellent, and the 2 html files are interesting for folks to see as inspirations of what to write and how to redirect to an external site.

Especially if they're nice and fancy with CSS!

Example or template code is always nice to have.

@robi I'm sorry to disappoint you, but the HTML files I created are very simple. The fancy stuff happens on the uptime kuma page. If you are still interested, here's the code:
