SCO Parameters
The following parameters affect the SCO only. If you change any of these
parameters, you must restart the SCO.
• HistoryEventDays (days)
Default: 7
Range: 1 - 365
How many days of history events to save. At midnight, history events
older than the specified age are deleted.
• SCOLogExternMeas
Default: 0 (disabled)
Range: 0 (disabled) or 1 (enabled)
Enable or disable external measurement logging.
The SCOLogInterval parameter determines how often the SCO
writes external measurement data to a log file.
In UNIX, the external measurement log files are located in the
/var/opt/webqos/stats directory. In Windows, these files are
located in the <install-directory> \stats directory.
• SCOLogInterval (minutes)
Default: 5
Range: 1 - 1440 (24 hours)
How often, in minutes, WebQoS logs aggregate service statistics to a
service statistics log file. Service statistics logging must be enabled
using the management console before aggregate service statistics are
logged. See “Service Statistics” on page 50 for a list of the logged
aggregate statistics.
In UNIX, the service statistics log file is located in the
/var/opt/webqos/stats directory. In Windows, these files are
located in the <install-directory> \stats directory.
• ServiceSLOInterval (seconds)
Default: 30
Range: 5 - 43200 (12 hours)
How often, in seconds, the SCO monitors the service level SLOs.
