3-44 Chapter 3: Understanding the RSM LE Start Up Delay The Start Up Delay setting determines how long RSM waits after startup before it begins monitoring. The default values are selected to provide the system time to fully start up before monitoring begins and to not start all monitoring at the same time. If the Start Up Delay is changed, the change takes effect on the next startup. Monitoring Interval The Monitoring Interval setting determines how often periodic checks occur after monitoring begins. If the Monitoring Interval is changed, the change takes effect immediately and the interval starts over. If the Monitoring Interval is set to zero, that particular OS Monitoring occurs once on startup (after the Start Up Delay period) and then ends. Any error that occurs when the checks occur on startup results in SOH transitions to an error state. These SOH errors cannot be cleared until the next time the monitoring is done and the condition that caused the error has cleared up, either on the next startup or if the monitor interval is changed to some periodic value. If you intend to use Monitor Interval of zero, you may want to consider changing the configuration of your system to use Critical Events instead of SOH for the related error conditions. If the Monitoring Interval is set to zero, the related monitoring thread ends after the check is done, to conserve system resources. If you change the monitoring interval later so that periodic checks occur, the thread is started up again as at startup. The Startup Delay period is used first as on startup, and then the periodic Monitoring Interval is used after that. If an error was logged for some condition on startup and the condition is still present after the monitoring restarts, it does not remember that it already logged an event for that error condition on the initial startup and will log it again. To access the OS Monitoring parameters, select Administration→OS Monitoring. The following are the three sections defined for OS Monitoring: CPU & Memory Disks & Files Processes & Services
Chapter 3: Understanding the RSM LE 3-45 CPU and Memory The CPU & Memory tab displays the monitoring information for CPU and memory usage of the overall system. System–wide Monitor The System–wide Monitor displays the following monitoring settings for CPU and memory usage: Information System–wide Monitoring System–wide Monitor Interval System–wide Start Up Delay Definition Refers to the option to enable or disable the monitoring of CPU and memory usage. Refers to the time (in seconds) that determines how often the RSM application checks the CPU and memory usage. If you set the monitor interval to zero, the monitoring of CPU and memory usage occurs only at the startup of the NCRLoader. Refers refers to the time (in minutes) before monitoring of CPU and memory usage starts at the startup of the NCRLoader. You can set this to allow time for the system startup to complete before monitoring begins since high activity during startup may be normal. Changes to this setting take effect on the next startup.
