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.

This metric is unavailable when the network card’s maximum bandwidth is not reported by the kernel.

HostProcess topology object

The HostProcess type captures aggregate metrics for all processes of a given type on the host. Processes are aggregated according to executables.

HostProcessInstance topology object

The HostProcessInstance complex observation captures detailed per-process statistics, but that observation may not be produced at all times.

This metric is available only on AIX systems using native collectors. The value represents the sum of bytes read and written by the process.

Some data necessary to calculate these metrics require use of sudo for the agent to collect. (For more information about sudo commands that require root access, see Configuring secure launcher permissions using sudo.) These values and the information derived from them, such as the Top 5 Processes by Disk I/O, cannot be considered fully accurate, because the Solaris kernel does not always update these metrics when the disk I/O is done on behalf of a process. As a result, these metrics should be treated as indications of the general amount of disk I/O that is done, rather than hard numbers.

HostService topology object

The HostService complex topology object captures information about the Windows® service.
