How do I convert apache.status.uptime.server_uptime to human readable format and display it in a Visualization? I've tried multiple times in a scripted field but can't seem to get that to work either. Thanks.
Are you getting the value in seconds like from server-status?auto? If so, you should be able to divide by 86400 to get days, or 3600 to get hours.
Try with something like this in the scripted field
long days = ((doc['field'].value.getMillis()/1000)/86400);
