Hi,  
I'll do an ELK-Stack with an alertingsystem.  
So my suggestion was somthing like this:

Shipper =\> Redis =\> Indexer =\> ES \<= **Alerting** (Logstash)

Can Logstash read logstash(Alerting) read or use logfiles, if my configfile looks like this:

```
input {
   elasticsearch {...}
}
output {
   email {...}
}

```

or is this the complete wrong way?

Don't do this. Logstash won't make a good alerting system. Either use Elastic's own Watcher or use a proper alerting system like Nagios or Icinga and have it poll ES.
