4.5.4 Guidelines for disk space requirements for the operation log database
Use the following formula as a guideline for estimating the disk space required for automatically restoring operation logs to the database.
- When all the operation logs are acquired
-
Number of managed computers x Period for storing automatically restored operation logs (days)# x 1.52 (MB) = Disk space required for automatic restoration (in MB)
#: The period for storing automatically restored operation logs is 300 days at maximum.
However, if the disk space required for automatic restoration is less than Period for storing automatically restored operation logs (days) x 1.5 (GB), the guideline for the disk space should be Period for storing automatically restored operation logs (days) x 1.5 (GB).
The following shows a guideline for the disk space required when the number of automatically restored operation logs is 100,000,000 and 300,000,000.
- With 100,000,000 operation logs
-
54.7 GB
- With 300,000,000 operation logs
-
161.0 GB
When the number of automatically restored operation logs is 100,000,000 and 300,000,000, the operation logs can be stored in the database for the following period.
|
Number of managed computers |
Guideline for the number of days during which the operation logs can be stored |
|
|---|---|---|
|
100,000,000 operation logs (54.7 GB of disk space) |
300,000,000 operation logs (161.0 GB of disk space) |
|
|
500 |
4 months |
1 year |
|

2 months |
6 months |
|

1 month |
3 months |
|

2 weeks |

|
10,000 |
1 week |
3 weeks |
|
30,000 |
3 days |
1 week |
Note: A month is calculated as 20 business days.
Use the following formula for estimating the disk space required when you manually restore the operation logs.
- When you manually restore the operation logs for 3 months for 200 managed computers
-
90 days x 1.5 (GB) = 135 (GB)
