not populated with logstash output

(Christiaan Van Aken) #1

Data from Metricbeat is send to my central Logstash server and from there the output goes to Elasticsearch. If I do this, the field is always empty. If I change the Metricbeat configuration to send it to Elasticsearch directly, the field is correctly filled in with the hostname. I followed the manual for installing and configuring Metricbeat.

Please help!

Why do you use the json codec?

Well it does not matter if I put it in there or not. Either way it does give me the

Can you enable the ruby debug output on LS to see if the events you receive that the set in it?

output received {"event"=>{"@timestamp"=>2017-05-24T12:48:18.417Z, "system"=>{"process"=>{"memory"=>{"rss"=>{"pct"=>0.0009, "bytes"=>3497984}, "size"=>224391168, "share"=>2859008}, "cmdline"=>"/usr/local/psa/admin/bin/modules/watchdog/monit -Ic /usr/local/psa/etc/modules/watchdog/monitrc", "pgid"=>824, "name"=>"monit", "cpu"=>{"start_time"=>"2017-05-02T22:03:36.000Z", "total"=>{"pct"=>0.0}}, "pid"=>824, "state"=>"sleeping", "fd"=>{"limit"=>{"hard"=>4096, "soft"=>1024}, "open"=>5}, "ppid"=>1, "username"=>"root"}}, "host"=>"", "metricset"=>{"rtt"=>55135, "module"=>"system", "name"=>"process"}, "GeoLocation"=>{}}}

I suppressed the real hostname, but it looks like the beat stuff is not coming to LS.
