Data from Filebeat Not Showing in Elastic

Hi, Hoping you can help.

I am fairly new to Elastic Stack, but the company i work for have a running implementation monitoring Apache logs.

I am attempting to add to the functionality by also monitoring the access log of some of our servers.

I have Filebeat set up and running (config says OK), and i have the config file and pipeline set up in logstash

However there is no data showing up in Kibana, and i don't know what i have missed.

Can anyone point me in the right direction?

Thanks in advance

To add to this slightly, i have now got logstash logs showing that the pipeline is running, and it seems to be sending everything where it is meant to go.

Nothing showing on Kibana though
