I have been using the default dashboards given with Metricbeat. They are cool and have all the required features built-in. But there is a problem when I use with Auto-refresh turned on. A few of the metrices (like Disk used[Metricbeat System], Disk Usage[Metricbeat System], Memory Usage Guage[Metricbeat System] etc.) drop to 0 each time the dashboard gets refreshed. Is there a way to prevent the value from dropping to 0? I'm using Elastic Stack 6.2.0.
