Logs

Indicates what level of detail messages should be shown in the messages pane.

Standard values pertain only to detail messages; customizing allows finer control of the level:

Possible values:

• Essential - 0
• Low - 1
• Medium - 2
• High - 3
• Custom

Default value: High - 3

Indicates whether a system log file should be:

• continually appended to, or
• overwritten each time the Cleo Harmony, Cleo VLTrader, or Cleo LexiCom software is started, or
• not created at all.

Possible values:

• Append
• Overwrite
• None

Default value: Append

Indicates whether any log event for any node in the cluster should be replicated across the cluster. The Cleo Harmony and Cleo VLTrader applications use a self-contained, distributed NoSQL database for this purpose. This option must be turned on for transfers and events information to be available through the REST API and, hence, the Cleo Portal and several of the newer UI reports (for example, Transfers and Logs).

Possible values: On or Off

Default value: On

Note: It is strongly recommended that this switch remain On, as reliance on the distributed NoSQL database will increase as new Cleo Harmony and Cleo VLTrader software features are introduced.

When transitioning this switch from Off to On, all users should log out and back in to view the new UI displays. Along with this, since the newer UI reports come strictly from data within the NoSQL database, it will take a while for historical data to collect.

When switching from On to off, all users must log out and back in to see up-to-date data for the event log and transfer report.

Indicates whether a CRC-32 value should be computed on file transfers.  If computed, a CRC value is recorded in the <Result> element of the system log file; and further, if database transfer logging is enabled, the CRC will be stored in the database as well.

Note:  If special EOL processing is associated with the transfer (e.g., 'Fixed Record Outgoing Insert EOL' is on), CRC computations will take place after EOL processing on outbound payloads and before EOL processing on inbound payloads.

Possible values: selected or unselected

Default value: unselected.

This is a Cleo Harmony and Cleo VLTrader option.

When the ‘Log errors’ selection is enabled, indicates that all errors and exceptions will be logged in either the Windows Event Log or the Unix Syslog.  In Unix, messages larger than the size of the Syslog record entry will be truncated.

Additionally, logging of warnings may be selected but requires that error logging has also been enabled.

When enabled, System Event logging will be done in addition to “Email On Fail”.  Suppression of repetitive messages used for emailing does not apply to System Event logging.

If you select either of these options and you are running Harmony or VLTrader as a daemon on systemd, you must make sure your Unit file contains the following:

[Service]
Type=simple
ExecStart=/root/Harmony/Harmonyc -s service
ExecStop=/root/Harmony/Harmonyc -s service,stop

In addition, if stdout and stderr are not being sent to journald, include the following:

StandardOutput=journal
StandardError=journal

For more information, see Starting as a daemon on systemd.

Note: On newer versions of Linux and Unix Solaris 2.6+, it’s possible that the remote Syslog capability was disabled and may require additional configuration.  Refer to Knowledgebase # 2416 for further information.

Possible values: selected or unselected

Default value: unselected

Indicates what level of messages should be logged to the system log file.

Standard values pertain only to detail messages; customizing allows finer control of the level:

Possible values:

• Essential - 0
• Low - 1
• Medium - 2
• High - 3
• Custom

Default value: High - 3

Indicates whether the system log file should be automatically archived when it reaches the maximum size.

Possible values: selected or unselected

Default value: selected.

In addition to archiving when it reaches the maximum size, indicates whether the system log file should be archived at the end of every day or every week (Sun-Sat).

Possible values: selected or unselected

Default value: unselected
