no more alert notifications since last update

I don't understand anything : since last night, without any new action on our part, we receive all the alerts again.
It was as if the tool had been in global maintenance for 1 week.
Except that, of course, there was no scheduled maintenance, and none appears in the history.

Could it be that the tool is consider a "ghost" maintenance?
=> that something were scheduled / cancelled, and was finally considered, without appearing in the interface?

I'm glad that's working now, but it's really a strange thing...
if you have any explanation / theory: I take it !
Could be useful in the futur.

You don't really need to do the rebuild thing, certainly not after updates or reboots.

The alert test script uses basically the same path of generating a notification that the normal poller does, so I'm not sure what might not be working, since you're getting other notifications via other contacts, and testing the telegram contact works.

You should probably make screenshots of all of the relevant parts in the chain, showing configuration of checker and contact, and alert log entries which didn't generate a telegram notification.

As i said in my comment 3 days ago :
I clicked on "rebuild" after the update and reboot of the master.

I also tried setting up a new alert, then clicking rebuild again.

do you have another process to follow?

we didn't get any notifications during the whole weekend, and it's becoming very annoying not to be able to react in time.

Are you sure the alert was triggered?

yes, we received this test alert message on telegram.

we still do not receive the current notifications that are supposed to be sent by the checkers

well... it's work better with an accurate contact id...

(the last number taken for testing was the "recipient":"-1001158003268")

see the test_alert-c1.txt file in attachment ; note that we did get a message on telegram after this script

You didn't include the command you ran to get this output.

Why does it think you gave it that weird number as a contact id? What contact id did you give it?

oops, sorry, you're right i didn't saw this request.

here is the result in attachment : test_alert.txt

this line appeals to me:

o Unknown contact Contact ID -1001158003268 not exist.

yet this configuration was previously functional.

See mike's request for output of the test alert command.

I don't get it : what do you need?

what is the process?

we are on an : Observium Enterprise edition (id = Coverage-2165593)
