A performance report takes the CPU, memory, disk, and network data covered in Performance Monitoring and turns it into a summarized view over a chosen period, suitable for review or sharing rather than reading straight off a live dashboard graph.
What's in a performance report
- Trend graphs for the selected metric(s), across one host, a host group, or your whole environment
- A chosen time range (a week, a month, a custom period) and aggregation method — the same Min/Avg/Max concepts covered in Performance Metrics apply here too
- Peak and average figures for the period, useful for spotting whether normal load has been quietly creeping up
- A comparison view, where supported, against a previous period of the same length
Generating one
- Choose the scope — a single host, a host group, or a broader selection.
- Pick the metric(s) to include and the time period to cover.
- Choose the aggregation method appropriate to what you're trying to show — Avg for a smooth trend line, Max if spikes are what matters.
- Generate the report, then export or share it as needed.
Common uses
- Capacity planning — a report spanning several months makes a slow upward trend in resource usage obvious in a way a single dashboard graph rarely does
- Change validation — pulling a report for the period just before and after a configuration change or upgrade, to confirm it had the intended effect
- Routine infrastructure reviews — a recurring summary for a technical team or stakeholder who doesn't need day-to-day dashboard access
For a report that needs to go out automatically on a recurring basis rather than being generated on demand, see Scheduled Reports.
