Kibana JSON input calc fields

[Robin020 (R)]

Hi,

I use heartbeat for monitoring some url's. But unfortunately the resolving of my VPS is slow. So I would like to exclude the resolve.rtt.us field in a visualization.

In the visualization I use the monitor.duration.us field on the Y as. I try to do this calculation: monitor.duration.us - resolve.rtt.us.

{"script" : "doc['monitor.duration.us'].value - doc['resolve.rtt.us'].value"}

Above JSON input doesn't work. Could somebody help me with this?

Best regards,
Robin

Hi @Robin020,

@Robin020

Above JSON input doesn't work. Could somebody help me with this?

Do you get a specific error message? Can you show me exactly where and how you're trying to use this script?
