• 3 visualizations ( Uptime, Total accesses, Total egress ) (Overview dashboard) are not migrated due to Not having feature to set last bucket value
• Uptime is also not migrated due to Not able to convert value into human readable format ( Seconds / Minutes / Hours )
• 3 visualizations ( Scoreboard, Load1/5/15, CPU usage ) (Overview dashboard) and 1 visualization ( Top URLs by response code ) (Access and error logs dashboard) are not migrated due to Splitting a chart into multiple smaller charts by a breakdown dimension is not supported in the lens
