Information that applies to all sensors

Point North Networks Server Monitor offers a wide range of sensor types to monitor many different aspects of a network device. When creating and editing sensors there are special parameters for each sensor type and there are also some parameters that are available for all sensors.

The following parameters are common to all sensors:

· Associated Server—use the drop-down menu to select a server to which to attach this sensor

· Name—enter a descriptive name for the sensor

· Comments—enter a description for the sensor (i.e., what it does or when it will check)

· Status—use the drop-down menu to set the status of the sensor (Active or Paused)

· Dependency—You can pause this sensor if a sensor of another server is not UP. Choose the dependency sensor from the dropdown list. Do not choose the current sensor itself and avoid circular dependencies. Use with caution. See “Managing Dependencies”.

· Schedule – allows you to select a schedule defined under My Account. From the drop-down menu you can select from the defined schedules.

· Probe – If the admin has set up more than one remote probe you can select one or more probes from the list to monitor a server or service from various locations.

· Interval—use the drop-down menu to select an available interval.

· Latencies - "Latencies" are used to defer notifications after warnings or errors have occurred. You can set latencies on group, server and sensor level. The latencies for warnings, errors and escalations can be set individually. Choose “Use Group Settings” if you want this server to use the latency settings of the associated group or choose the latencies for this server individually.

· Notifications - "Notifications" are used to send alarms when warnings or errors occur. You can set notifications for groups, servers and sensors. Choose “Use Group Settings” if you want this server to use the notifications of the associated group or choose the notifications for this server individually.

Most sensors also have one or more of the following common parameters:

· Timeout—specify a time (in seconds) when the sensor should stop trying to accomplish its objective and send a failure notification

· Warning level—specify a time (in seconds) when the response time of the sensor should generate a warning notification. If you have the On Warning Notification set to active, this will determine when the notification is sent.
