Status and State
Various PCC views show the current life cycle states of smart cells or the
status values of particular hosts or services. A status value measures relative
health. It can be associated with a
status condition that conveys a measure of
confidence in the reported value. This section defines the possible life cycle
states, status values, and status conditions.
For example, the health of a smart cell in the life cycle state
DEAD can be
reported with host status value
DOWN . If the host status value has been
checked the required number of times, the status condition is reported as
HARD (otherwise it is SOFT ).
PCC views (see
User Interface Components , on page 2-2) often use the terms
“status” and “state” loosely, and interchangeably when referring to hosts and
services. They always use “state” when referring to smart cell life cycle states,
but they use both “status” and “state” when reporting on the health of a
smart cell, regarding it as a host like any other. PCC views also refer to a
status condition as a “state” or “state type.”
Status of system components is color coded:
green indicates normal
operation;
red indicates the component has stopped or failed; yellow indicates
a warning. See
Host and Service Status Value Definitions , on page 1-6.
Smart Cell Life Cycle State Definitions
The following table defines the possible smart cell life cycle states.

DISCOVERY The metaserver and the smart cell are determining
the
start state for the cell (state following
DISCOVERY), based on the expected states of the cell
and its mirror smart cell.
The cell is not available for document storage,
search, or retrieval.
