3.4.2 Estimating the size of the operation log file
To estimate the size of the operation log file, consider your required usage of Navigation Platform, using the following table as a reference.
No. |
Item |
Scale (numbers) |
---|---|---|
1 |
Number of users interacting with an Operational Content Execution Window per day |
10 |
2 |
Number of Operational Contents to be executed per user per hour |
6 |
3 |
Number of nodes per Operational Content |
10 |
4 |
Actual hours of work on Navigation Platform per day |
8 hours |
5 |
Length of time to retain the operation log |
180 days# |
If you plan to use Navigation Platform on a scale different from the numbers shown in the table, you must estimate the disk space required according to the formulas below.
- Organization of this subsection
(1) Formulas for estimating the size of the operation log file (when using URLs without ucnpOptions parameters)
- Formula when the property ucnp.base.server.operationlog.user.analyze.info is true
-
In Table 3-3 Usage of operation log assumed by Navigation Platform, 1.0 × {(numbers assumed for the environment to be set up corresponding to rows 1 to 4 in the table} divided individually and then multiplied by (numbers in rows 1 to 4 in the table} = operation log file size required for the environment to be set up (unit: GB)
- Formula when the property ucnp.base.server.operationlog.user.analyze.info is false
-
Calculation result of the estimation formula when the property ucnp.base.server.operationlog.user.analyze.info is true × 0.25 = operation log file size required for the environment to be set up (unit: GB)
- Estimation example
-
-
In the environment to be set up, the assumed number of users (No. 1 in Table 3-3 Usage of operation log assumed by Navigation Platform) is 20.
-
In the environment to be set up, the assumed number of Operational Contents to be executed per user per hour (No. 2 in Table 3-3 Usage of operation log assumed by Navigation Platform) is 9.
-
The property ucnp.base.server.operationlog.user.analyze.info is set to true
The operation log file size required for an environment satisfying these conditions can be calculated as follows:
1.0 × {20 ÷ 10} × {9 ÷ 6} = 1 × 2 × 1.5 = 3.0 GB
-
- Tip
-
If the operation log file becomes too large, it becomes difficult to analyze for your own purposes. Therefore, if there is no need to analyze the operation log for your own purposes, we recommend specifying false for the property ucnp.base.server.operationlog.user.analyze.info in the user property file (ucnp_user.properties).
(2) Formula for estimating the size of the operation log file (when using URLs with ucnpOptions parameters)
If the URL to access Navigation Platform includes ucnpOptions parameters, the values specified in the ucnpOptions parameters will be added to the operation log. This means the results of the following formula must be added to the calculation results of the estimation formula in 3.4.2(1) Formulas for estimating the size of the operation log file (when using URLs without ucnpOptions parameters).
- Formula for the operation log file size required for ucnpOptions parameters
-
Size of the ucnpOptions parameter × row 1 × row 2 × row 3 × row 4 in Table 3-3 Usage of operation log assumed by Navigation Platform× 180 = operation log file size required for the ucnpOptions parameter (unit: GB)
