Host topology object

Host objects are identified in Foglight by their Name property. This property typically contains the host’s fully qualified domain name. The fully qualified name is also decomposed into the localName and domainName properties. The IP addresses assigned to a host are captured in the primaryIpAddress and ipAddresses properties. The addresses are not unique to a particular host.

The percentage of paging space available on the host.

HostCPUs topology object

There is a single HostCPUs instance attached to a Host that provides host level summary metrics for the processors on a host. The HostCPUs instance is identified by the reference to the associated Host object and has its name set with the constant string CPUs.

The average percentage of time that processors on the host were idle while there was at least one I/O in progress.

HostCPUs — Physical CPU Utilization

The CPU usage of AIX® LPAR (Logical Partition) is not easily or consistently measurable via a percentage. Depending on the LPAR configuration, the numbers can vary widely (often exceeding 100%, as in prior releases).

The current formula for calculating the Physical CPU Utilization provides a more meaningful value for this metric, which is reflective of physical CPU allocation (regardless of virtualization setup) and does not exceed 100%.

Customers who prefer using the old formula from the legacy agent (delivered with the Cartridge for Operating Systems) can revert to the old calculation by using the following formulas:

HostNetwork topology object

There is a single HostNetwork instance attached to a host that provides host level summary metrics for the network interfaces on the host. The HostNetwork instance is identified by the reference to the associated Host object and has its name set with the constant string Network.
