• "all" (default)
• "info"
• "warning"
• "error"

Defines the message types to be shown. The parameter is a string of comma delimited words.

Example:

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

Examples:

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

• "default" - default value, 7 days. This value 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 the next log file based on a period of time. If enabled, the switching to the next log file occurs at midnight.

Examples:

Specifies if repeated messages should be filtered or not. Possible values are "on" and "off" (default).

If the value is "on", immediately following messages with the same identifier and system error code are not listed in the log but they are counted. When a different log message is generated, the repeat count of the earlier log message is reported with the entry "The previous message has been repeated N times." and the counter is cleared.

Stromasys highly recommends to let this value to "off" otherwise important information will not be reported in the log file.

Example:

• <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)

Examples:

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:

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.

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

By default the Charon VM 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:

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

Syntax:

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:

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

Example 2:

Same as above but retry in 30 seconds.

Example 3:

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

Example 4:

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