How can I measure Iguana Server system requirements?

Windows: View Disk

After an hour of running Iguana, the disk usage stats are as follows:

Disk Usage Counter Description Average Value Suggested Average Threshold
Disk Transfers/sec Rate of read and write operations on the disk. 18.138 disk transfers/sec The accepted value depends largely on the manufacturer’s specifications.

Disk Usage Counter Description Average Value Suggested Average Threshold
Disk Write Bytes/sec Rate at which bytes are transferred to the disk during write operations. ~145 KB/sec = 12.528 GB/24-hour period The accepted value depends largely on the manufacturer’s specifications.

Disk Usage Counter Description Average Value Suggested Average Threshold
Disk Idle Time (%) Percentage of time that the disk was idle during the specified interval. ~99% disk idle time 90% and above

Disk Usage Counter Description Average Value Percent Value Suggested Average Threshold
Free Space (%) Ratio of free space available on the logical disk unit to the total usable space provided by the selected logical disk drive. ~34 MB/hour 0.166% Depends on the volume of messages you are expecting.

To calculate your disk usage using the results found above, you would do the following:

63.825 (Maximum Value) - 63.659 (Minimum Value) = 0.166%/100% x 21,476,171,776 Bytes (Capacity of Hard Drive) = 35650445.14816 (Total Bytes)

To get the value in KB and MB, you would do the following:

35650445.14816 / 1024 / 1024 = ~34 MB

This means that Iguana writes approximately 34 MB to the disk every hour (assuming the message size is ~1 KB). This number will obviously fluctuate, depending on the size of your messages.
