Hosts

The Hosts tab in the Environment console displays all of the hosts associated with an IdentityIQ instance, along with statistics about the state of each host in the selected column.

A search box in the upper right lets you search for servers. This is a "starts with" search rather than a full-text search, and it is not case-sensitive.

You can add, remove, or reorder the columns on this tab. Columns may include:

• Host Name – name of the machine hosting the IdentityIQ instance.

• Status – a color-coded arrow icon indicating whether the host is up or down.

• Last Heartbeat – the last time the host verified its functionality. Each host periodically sets a date in the server object to verify it is still running. If the verification date does not advance for a specified period of time, the other servers detect and mark the server as having crashed.

• CPU – a percentage representation of the workload sustained by the host machine CPU.

• Memory Percentage – the percentage of the maximum allowed memory which is actively in use by the application server's Java virtual machine.

• Request Threads – the number of request processor threads running on this host.

• Timestamp – the last time the monitoring service ran.

• Database Response Time – the number of milliseconds it last took to connect to the database and query from it.

• Task Threads – the number of background tasks running on this host.

• Memory – the amount of memory (in bytes) actively in use by the application server's Java virtual machine.

• Host Actions – action buttons to configure or delete hosts.

Note: For hosts running on Unix operating systems, there is an option, Open Files—Unix Only, that displays the number of open files to avoid running out of file handles. This count is on the operating system, not the application server. This column can only be enabled manually from the UI Configuration object on the debug pages.
