Get Data from heartbeat but can't show uptime in below

That is odd. Do you see any errors in your browser's debug console?
I need to send netflow data to show on kibana dashboard (Filebeat Module)
From Image, I find main 2 error 
"ERROR   registrar/registrar.go:374      Writing of registry returned error: rename /var/lib/filebeat/registry/filebeat/data.json.new /var/lib/filebeat/registry/filebeat/data.json: no such file or directory. Continuing..."
and
"ERROR   [netflow]       netflow/input.go:161    Error running harvester: listen udp 127.0.0.1:2055: bind: address already in use
"
How solve this problem ?
Did you post the right reply here? This thread is about heartbeat.
Sorry, I just change and add more question about elasticsearch
