Status Alarms
If any process that keepalive monitors has a yellow or red alarm status,
the yellow or red icon is displayed next to the node listed in the left-hand
pane. When you select (double click on) the node to see the list of processes,
the alarm icon appears next to the process that caused the alarm.
Red
The red alarm status indicates the process has failed and is not running
(the process is in the down state).
Yellow
The yellow alarm status normally indicates that the process has failed
at least once and is either running again after being restarted or is in
the process of being restarted. Yellow may also mean:
-
The process has been designated to run on one or more nodes and those nodes
are not available.
-
The process may have been shut down with the spawndameon command or is
part of a group that is temporarily shut down because one of its critical
members failed.
You can determine why a process is yellow by selecting it and looking at
its state attribute. See Keepalive Process Attributes
help for an explanation of keepalive process states.
Green
The green alarm status indicates that the process is executing and
has not failed (the process is in the ok state).

process state and error (failure) count attributes.
