Capacity planning modules assist in making proper long-term storage strategies. With this module, we can easily visualize non-standard growth patterns in our disks, directories, databases or files.
The default sampling interval for the capacity planning agent samples is daily.
Note: By default when using this module aim to have a longer time range selected (a week or above).
| Legend | |
| 1 | Disk/partition related information. The collected disks are of above 5G. For each disk, the following information is displayed:
|
| 2 | Disk important OS directory size distribution. For each directory, we can see the total size and the growth for the selected timeframe.
By default, the directories that are sampled are backup directories or mdf ldf file locations. |
Capacity Planning – Part 2
The prediction visualization chart:
The prediction chart is split into two parts. The first part (on the left) is created from actual data that has been sampled. The second part (on the right after the separator line) is the predictive part. The series is then drawn by using a dotted line to show the prediction.
Each prediction is based on the previous growth using basic linear mathematic equations.
Use this module to decide the proper time for an enlargement of disk space.
As with the rest of the capacity planning module – we suggest using long timeframes when using this module, as the sampling intervals are daily.
Chart options are depicted in the legend below.

Percent Of Use Vs. Percentage Of Growth |
| 3 | Database growth prediction chart. Shows the total size of the actual database vs. expected growth. |
Percent Of Use Vs. Percentage Of Growth
Percent of use – the total percent from the usage. For example, if C:, the first sample is 10G, and the second sample is 15G, the percentage growth will be 50%.
Percent of growth – the growth in actual values (see Y axis on chart). For example, if C:, the first sample is 20G, and the second sample is 21G. The growth will be of 1G.
Prediction Size From Chart
The size of the prediction part from the total size of the chart.
Prediction Grouping
The prediction grouping goes hand in hand with the selected timeframe. If your selected timeframe, for example, is for last month, selecting a week range will group results by week, giving approximately four points for each series in the left part of the chart.
Selecting a day range will result in approximately 30 dots for each series on the left of the chart.
