Hello, This log is unrelated to your issue. If Logstash isn't sending data to Elasticsearch you will have more logs that reference the elasticsearch output, please share those logs. Also, what does your logstash configuration looks like? ---

This is saying the data stream names contains illegal characters. What does your output filter look like? ---

> [@Uzzi](#): > > I'm tryng to filter fortinet logs You need to share your logstash configuration, the error says that you are trying to use unsupported characters in the name of the data\_stream. It is not possible to now how you are naming the data\_stream unless you share your logstash configuration. ---

> [@Uzzi](#): > > Could you suggest me how to fix first cgroup problem? This depends entirely on your infrastructure, you didn't say what is your VM OS, how you are using it. But as I said, this is unrelated to your issue, if you want to fix it you should open another topic or edit this one. Also, if you search the forum about this issue there will be a couple of posts about it. ---
