Hello  
I am having 2 issues with logstash:

1. i have installed winlogbeat on my windows servers. I see that redis is getting all the logs and while looking into logstash-plain.log, i saw errors of type invalid index name. Index cannot contain chsraxters .....

I want to have like syslog-(machinename)-win on kibana. Can you please guide?

1. if for example i will be adding syslog of linux servers, apache logs,etc. How can i configure logstash to parse the logs and have index like

Syslog-(machinename)-(logtype) on kibana?

Thanks,

If I recall correctly there are some characters that are not allowed and I also think index names need to be all lower case.

It should to me like this will result in [a lot of very small indices and shards which is very inefficient and is very likely to lead to performance problems](https://www.elastic.co/blog/how-many-shards-should-i-have-in-my-elasticsearch-cluster). Why can these not live in a single time-based index?
