The APM system looks really promising, and I'm hoping we'll be able to use it to solve our needs.
We've a slightly difficult situation as we've an app that runs in the cloud, but also on client operated site boxes. Site boxes are often offline when in use, and we synchronise data when they next have an internet connection.
We've successfully managed to collect logs by using Logstash's persistent queues, and we're investigating using metricbeat (outputting to Logstash) for system metrics for our site boxes. We're also looking for an APM solution, and I'm hoping that Elastic's APM Server will be up to the job.
Currently, the documentation doesn't mention any way of configuring APM Server to output to Logstash.
Is there any way we could support offline collection of metrics using APM Server (either by outputting to Logstash or otherwise)? If not, is this something that's planned?
