Users are starting to use these mistakenly thinking they'll help
with issues, and thus causing some confusion.
Thus hide them and make it clear that they're only there for testing
reasons.
The docs suggest that alert templating only works in the summary and
description annotation fields. Some testing and a review of the code
suggests this is no longer true and that you can template any
annotation field.
remove some select state that is most likely obsoleete and hoepfully doesn't braje anything :)
merge targets will sort by Discoverer name so we can have consistent tests for the maps.
As discussed generally consider SDs as unstable, as realistically they
are never going to be. Drop the words "experimental/beta" from most
places in the docs, as users are getting the wrong impression from this.
Currently when sending alerts via the go routine within `sendAll`, the value
of `ams` is not passed to the routine, causing it to use the updated value of `ams`.
Example config:
```
alerting:
alertmanagers:
- basic_auth:
username: 'prometheus'
password: 'test123'
static_configs:
- targets:
- localhost:9094
- static_configs:
- targets:
- localhost:9095
```
In this example alerts sent to `localhost:9094` fail with:
```
level=error ts=2017-10-12T10:03:53.456819948Z caller=notifier.go:445
component=notifier alertmanager=http://localhost:9094/api/v1/alerts
count=1 msg="Error sending alert" err="bad response status 401
Unauthorized"
```
If you change the order to be:
```
alerting:
alertmanagers:
- static_configs:
- targets:
- localhost:9095
- basic_auth:
username: 'prometheus'
password: 'test123'
static_configs:
- targets:
- localhost:9094
```
It works as expected.
This commit changes the behavour so `ams` is passed to the go routine so
`n.sendOne` uses the appropriate `http.Client` details.
net.Listener converts 0.0.0.0 to :: which fails for hosts where IPv6 is
disabled. This change uses the original listen address parameter instead
of grpcl.Addr().String().
