Manager Status - Field Help

Configuration Settings

Edit any of the values on the Configuration Settings tab, then click Update Configuration.

Sensitivity level
A number from 1-to-100, used as the weight percentage to set the minimum sensitivity to weights update. This setting defines when the manager should change its weighting for the server, based on external information. The default of 5 creates a minimum sensitivity of 5%.

Smoothing index
A positive floating point number representing an index that smooths the variations in weight when load balancing. The default value is 1.5.

Weights refresh cycle
A positive number representing the number of intervals that occur before the CSS switch is queried for a refresh of information about new and active connections. The default value is 1.

Update interval (seconds)
A positive number representing, in seconds, how often the manager updates weights of the servers to the CSS switch. The manager updates the criteria that the CSS switch uses to load balance client requests. The default value is 15.

Reach update interval (seconds)
A positive number representing the number of seconds between attempts to reach targets in the configuration. The default value is 15.

Manager logging level
The level at which the manager logs its activities. The range is None to Verbose, with None meaning nothing is logged and Verbose meaning everything is logged. The default is Minimal. Select from the following values:
  • None
  • Minimal
  • Basic
  • Moderate
  • Advanced
  • Verbose

Maximum manager log size (bytes)
Sets the maximum size of the manager log. When you set a maximum size for the log, the file wraps; when the file reaches the specified size, the subsequent entries are written from the top of the file, overwriting the previous log entries. This log size cannot be set smaller than the current size of the log. Log entries are time-stamped to display the order in which they were written. The higher you set the log level, the more carefully you must choose the log size, because you can quickly run out of space when logging at the higher levels.

You can specify a positive number greater than zero, or up to 1 MB. The log file may not reach the exact maximum size before overwriting, because the log entries vary in size. The default value is 1048576 kbytes.

Reach logging level
The level at which the manager logs the Reach activities. The range is None to Verbose, with None meaning nothing is logged and Verbose meaning everything is logged. The default is Minimal. Select from the following values:
  • None
  • Minimal
  • Basic
  • Moderate
  • Advanced
  • Verbose

Maximum reach log size (bytes)
An integer representing the maximum number of bytes logged by the reach advisor. The default value is 1048576.

Binary logging interval (seconds)
How often, in seconds, information is written to the binary logs. The binary logging feature allows server information to be stored in binary log files for each server defined in the configuration. The manager sends server information to the log server every manager interval. The information is written to the logs only when the specified log interval seconds elapse since the last record was written to the log. The default binary logging interval is 60. The following information is stored in the binary log for each server:
  • time stamp
  • nonforwarding address
  • cluster address
  • port number
  • server ID
  • server address
  • weight
  • total connections
  • active connections
  • port load value
  • HasPortLoad (boolean)
  • system load value
  • HasSystemLoad (boolean)

Note: There is some interaction between the settings of the manager interval and the log interval. Since information is provided to the log server than the manager interval, setting the log interval less than the manager interval is the same as setting both the intervals the same.

Binary log retention (hours)
The time, in hours, that log files are kept. Log files older than the retention hours specified are deleted. The default value is 24 hours.

Current Statistics

Metric port
The number of the port on which a system-monitoring program reports system loads. The default value is 10004.

Log file name
The name of the manager log file. The default is manager.log

Binary logging
Status for binary log setting. The default is off
