Historical Data Comparison

Compare current server statistics with historical data from a previous time period. This helps you identify trends, performance changes, and resource utilization patterns over time.

Period Selection: Choose both a historical period (to compare against) and a current period (to compare from). You can select predefined time periods or use custom date/time ranges.

Metrics Compared: All major statistics are compared including CPU usage, memory utilization, disk usage, network traffic rates (in/out), and disk I/O rates (read/write).

Visualizations: Side-by-side comparisons with visual indicators show percentage changes, absolute differences, and trend directions for each metric.

Export: Comparison data can be exported to CSV format for further analysis or reporting.

Total statistics in database: {{ $historicalComparison['total_stats'] }} @if($historicalComparison['total_stats'] == 0) - Statistics are collected automatically every hour. You can also create manual statistics using the "Create Statistics" button above. @elseif($historicalComparison['total_stats'] < 2) - At least 2 statistics are needed for comparison. Wait for more data to be collected or create a manual statistic. @endif
