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.

HostTopProcessEntry topology object

A process detected in one of the Top-N lists, such as the top ten CPU consumers or disk users.

For Linux platforms, these metrics are collected only by the UnixAgentPlus.
