Remarks

Consider the following remarks and requirements for this sensor:

Remark	Description
IBM Systems Director Platform Agent	This sensor requires the IBM Systems Director Platform Agent on the target system. For more information, see the Knowledge Base: What are the requirements to monitor IBM System x?
IPv6	This sensor supports IPv6.
Performance impact	This sensor has a low performance impact.
Lookups	This sensor uses lookups to determine the status values of one or more channels.
Limits	This sensor has predefined limits for several metrics.
IMM	This sensor can also run directly on an Integrated Management Module (IMM) network port and can show the overall health of IMMs.
Unexpected format	If the IBM device returns a string in an unexpected format for the percentage of fan revolutions (for example, "offline"), this sensor shows -1% in the corresponding channel. You can define the Down status for this via channel limits.
Knowledge Base	Knowledge Base: What are the requirements to monitor IBM System x? Knowledge Base: IBM System X sensors could not find any disk/data on this device (PE187/PE188/PE194)

The SNMP IBM System X System Health sensor can also run directly on an IMM network port and can show the overall health of IMMs.

Basic Sensor Settings

The sensor has the following default tags that are automatically predefined in the sensor's settings when you add the sensor:

snmpibmsystemhealthsensor
systemhealth

For more information about basic sensor settings, see section Sensor Settings.

IBM System X System Health Specific

Setting	Description
Source	The source of the measurement that this sensor monitors.
Measurement	The type of measurement that this sensor monitors.

Sensor Display

Setting	Description
Primary Channel	Select a channel from the list to define it as the primary channel. In the device tree, PRTG displays the last value of the primary channel below the sensor's name. The available options depend on what channels are available for this sensor. You can set a different primary channel later by clicking below a channel gauge on the sensor's Overview tab.
Graph Type	Define how this sensor shows different channels: Show channels independently (default): Show a graph for each channel. Stack channels on top of each other: Stack channels on top of each other to create a multi-channel graph. This generates a graph that visualizes the different components of your total traffic. You cannot use this option in combination with manual Vertical Axis Scaling (available in the channel settings).
Stack Unit	This setting is only visible if you select Stack channels on top of each other above. Select a unit from the list. PRTG stacks all channels with this unit on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. However, there is an advanced procedure to do so.

Description

Primary Channel

Select a channel from the list to define it as the primary channel. In the device tree, PRTG displays the last value of the primary channel below the sensor's name. The available options depend on what channels are available for this sensor.

You can set a different primary channel later by clicking below a channel gauge on the sensor's Overview tab.

Graph Type

Define how this sensor shows different channels:

Show channels independently (default): Show a graph for each channel.
Stack channels on top of each other: Stack channels on top of each other to create a multi-channel graph. This generates a graph that visualizes the different components of your total traffic.
You cannot use this option in combination with manual Vertical Axis Scaling (available in the channel settings).

Stack Unit

This setting is only visible if you select Stack channels on top of each other above.

Select a unit from the list. PRTG stacks all channels with this unit on top of each other. By default, you cannot exclude single channels from stacking if they use the selected unit. However, there is an advanced procedure to do so.

Inherited Settings

By default, all of these settings are inherited from objects that are higher in the hierarchy. We recommend that you change them centrally in the root group settings if necessary. To change a setting for this object only, click under the corresponding setting name to disable the inheritance and to display its options.

For more information, see section Inheritance of Settings.

Channel List

Which channels the sensor actually shows might depend on the target device, the available components, and the sensor setup.

Channel	Description
Ambient Temp	The ambient temperature
CMOS Battery	The CMOS battery voltage
CPU [#] Temp	The CPU temperature
Downtime	In the channel table on the Overview tab, this channel never shows any values. PRTG uses this channel in graphs and reports to show the amount of time in which the sensor was in the Down status.
Fan [#] Tach	The fan RPM or the percentage of the possible maximum
Overall Status	The overall status Up status: Normal, System Level Warning status: Non Critical Down status: Critical
SysBrd 3.3V	The 3.3V-system board voltage
SysBrd 5V	The 5V-system board voltage
SysBrd 12V	The 12V-system board voltage
