Hello,

I just want to know how a logical separation should/could look like for different types of devices.

Let's say I have a bunch of switches and a bunch of servers which can send syslog messages.  
How should I separate them in Elasticsearch (two groups: switches and servers)? How could this look like in the logstash configuration? Are there any guidelines?

Is there any function I can group devices? Maybe lets say all devices in a specific range will get index "X" and other ones get index "Y"?

Regards

You could do that with a conditional block and then add a tag to the event with mutate. That'd be the easiest way I can think of.

Are you using filebeat to send logs to Logstash?
