Page 11: Overview Of The Software Availability Manager
Event Log. SAM is one of two NEC-supplied MMC snap-ins. The other is the ftServer Management Console (ftSMC) snap-in, which is documented in the system administrator’s guide. SAM and ftSMC both monitor system functionality. Most of the elements (called... -

Instances are the system performance elements that you specify to be monitored; for instance, CPU usage, disk free space, and so on. The list of instances you can monitor appears on the Express5800/320Ma Monitored Instances tab of the SAM snap-in. (See “SAM Instances” on page 1-3 for a complete list of instances that you can monitor). -
Page 13: Sam Instances
Software Availability Manager SAM Instances You can monitor and configure the following instances: • Context Switches (Per Second). The number of switches per second from one thread to another. A context switch occurs when the processor stops processing one thread and starts processing another. Context switches per second is a measure of how the microkernel is distributing the CPU processing of threads and processes on the system. -

Warning messages. These are reports of the email alerts that SAM sent in response to configured threshold specifications. • Error messages. These are SAM-based errors, such as invalid configurations, or email failures caused by invalid addresses, and so on. Express5800/320Ma: Software Availability Manager... -
Page 15: Sam Settings Reference
You view and configure the SAM instances and their threshold values on the Express5800/320Ma Monitored Instances tab. To display the Express5800/320Ma Monitored Instances tab 1. On the Express5800/320Ma desktop, click the ftServer version Management Tools icon. 2. Right-click the ftServer Software Availability Manager icon, then click Properties. -
Page 16: Instance Parameters
Instance Parameters Instance Parameters Instances are the system performance elements that the Express5800/320Ma SAM monitors; for example, CPU usage, free disk space, and so on. A description of the instances and related settings follows. The Enable alerts for selected instance setting enables warnings and alarms to be generated when the monitored component highlighted in the Select Instance menu exceeds its thresholds. -
Page 17: Figure 2-3. Scan-Related Parameters
Instance Parameters If an instance’s value exceeds its threshold: • and Scan retry is disabled, a threshold violation has occurred. In this case, SAM does whatever it has been configured to do in the event of a threshold violation. For instance, it might send email notification or run a program. - Page 18 You must enable Scan idle in order to use Time between alerts. The maximum value for this parameter is 72 hours (259200 seconds). A more typical value is 3600 (1 hour). Express5800/320Ma: Software Availability Manager...
-
Page 19: Alert Thresholds
Figure 2-4 shows the threshold settings (as well as the Units parameters) on the Express5800/320Ma Monitored Instances tab. The figure shows High Threshold Warning and High Threshold Alarm as they might be set for the CPU Usage instance. A CPU Usage level of 80% causes a High Threshold Warning; a 90% usage level causes a High Threshold alarm. -
Page 20: Threshold Units
CPU is operating at 90% of capacity. On the other hand, the Memory Available instance’s Units parameter is set to Megabytes. Therefore, a Low Threshold Alarm value of 4 means that the system will produce a Low Threshold Alarm alert when only 4 MB of memory are available. Express5800/320Ma: Software Availability Manager... -
Page 21: How Sam Scans An Instance
How SAM Scans an Instance How SAM Scans an Instance SAM scans the instance at the Scan poll rate (for example, every 30 seconds). If it finds a threshold violation, it checks Scan retry and Number of scan retries. If Scan retry and (therefore) Number of scan retries are disabled, SAM issues an alert. (Therefore, if you disable Number of scan retries, a single threshold violation generates an alert condition.) If SAM finds a threshold violation and Scan retry and Number of scan retries are... -
