If log rotation is enabled, the log_file_size parameter determines the log file size threshold at which the log is automatically rotated. Rotating log file size is multiple of 64K

• "unlimited" or "0" (default) - the feature is disabled
• "default" - default size is used (4Mb)
• <size>[KMG] - size of the current log file in bytes with additional multipliers:

  • K - Kilobyte - multiply by 1024

  • M - Megabyte - multiply by 1024*1024

  • G - Gigabyte - multiply by 1024*1024*1024

Example 1:

set session log_file_size="default"

Example 2:

set session log_file_size=10M

 Minimum LOG File size is 64K, maximum is 1G. Setting size less than 64K effectively makes the LOG File unlimited.

• "default" - default value, 7 days. This values is used even if the "log_rotation_period" is not specified.
• "daily" or "1"
• "weekly" or "7"
• "never"
• <N> - in N days where N is greater than 0

If the rotation log mode is enabled this parameter controls switching to next log file based on period of time passed. If enabled the switching to next log file appears at midnight.

Example 1:

set session log_rotation_period="weekly"

Example 2:

set session log_rotation_period=14

• <period-in-seconds>

Defines a period of flushing log to disk.

Default period is 60 seconds (it means that every minute log file is flushed to disk)

Example:

set session log_flush_period=30

license_key_id

license_id

A set of license identifiers that specifies the licenses to be used by CHARON. This parameter is applicable only to licenses on which Stromasys placed restrictions on what products can be combined on a single license key. Please contact your Stromasys representative or VAR for more information.

Example:

set session license_id = "2718281828,314159265"

If this parameter is set, Charon considers for validation only the available licenses with license ID parameter set and equal to one of the license ID's specified in the configuration. This prioritized list corresponds to the "Product License Number" line in the Product section of the license.

In case the CHARON-AXP license connection is not present when the guest starts up, this parameter specifies how many times CHARON-AXP will try to establish the connection and, optionally, a period of time between retries.

Syntax:

set session license_key_lookup_retry = "N [, T]"

Options:

• N - Number of retries to look for license keys.
• T - Time between retries in seconds. If not specified 60 seconds are used

Example 1:

set session license_key_lookup_retry = 1

If license key is not found during initial scan, do only one more attempt after 60 seconds.

Example 2:

set session license_key_lookup_retry = "1,30"

Same as above but retry in 30 seconds.

Example 3:

set session license_key_lookup_retry = "3,10"

If license key is not found during initial scan, do 3 more attempts waiting 10 seconds between them.

Example 4:

set session license_key_lookup_retry = "5"

If license key is not found during the initial scan, do 5 more attempts waiting 60 seconds between them.

Limits the number of emulated CPUs.

Example:

set session n_of_cpus=3

The maximum number of CPUs enabled by CHARON-AXP is specified by the license key, but cannot exceed the original hardware restrictions. See table below.

This parameter specifies how many host CPUs CHARON-AXP must use for I/O handling. Use of the “affinity” parameter may limit the number of CPUs available.

By default the CHARON-AXP instance reserves one third of all available host CPUs for I/O processing (round down, at least one). The “n_of_io_cpus” parameter overrides that by specifying the number of CHARON I/O CPUs explicitly.

Example:

set session n_of_io_cpus=2
