Show refresh trigger in UI without having the updatable env endpoint

Hello SBA Team,

I just wanted to start an enhancement request regarding the /refresh endpoint please.

Currently, on server side, I do have:

spring.boot.admin.probed-endpoints=beans,caches,conditions,configprops,env,health,heapdump,info,loggers,mappings,metrics,scheduledtasks,threaddump,refresh

(note the last one on the list, refresh)

On app start up, after registration, I do see on client side (the service that is going to be registered to SBA server) log:

[or-http-epoll-4] reactor.netty.http.server.AccessLog      : 1x.1xx.1xx.1xx:45504 - - [18/Feb/2021:00:25:14 +0000] "OPTIONS /refresh HTTP/2.0" 200 - 13 ms

But that is all. No further call to refresh endpoint by SBA server.

It will be interesting on the SBA Serverside, maybe through the UI, to have a way to “trigger” those refresh (without making it a periodic poll like /health).

Many clients that expose the @refreshScope can benefits from this feature, making SBA server even more useful for dynamic content.

Thank you

I think this feature would be useful just with the /actuator/refresh. Could you make it work, please? I would not like to expose the /actuator/env push just for this.

Hello @joshiste,

So you are correct, I went to activate the /POST to /env, and was able to see the difference.

As expected, very well designed.

But the UI expect some kind of input, on the left and right side (two text boxes to fill)

I was more suggesting a simple refresh button, that will trigger the /refresh endpoint of the registered app, no matter the registered app has /env ready or not.

This way, the Admin will have the possibility to trigger the dynamic hot reload of properties of registered apps, which can be a very strong feature.

I believe it is what you said here:

“accept a PR that a refresh button is shown depending on whether /refresh is present or not (and don’t depend on the POST-ability of /env”
