Information Displayed

The summary screen displays the following identifying information:

The body of the Summary report displays the following information for the time period specified:
object type.name
The type and name for each object in the report. The object type is one of CLUS, NODE, TIME, or APPL.
down cnt
The number of times the object went down.
last went down when
The time of the most recent down event. This time is a date if the event did not occur the day of the report. If the down event occurred the day of the report, the time is noted by hours, minutes, and seconds using a twenty-four hour format.
total down time unplanned
The total amount of unplanned time the object was down in days, hours, minutes, and seconds. By default, all down time is logged in the event log as unplanned, but you can annotate the event log file to specify that down time is planned using the samlog -i evid -p PLANNED command.
total down time planned
The total amount of planned time the object was down. The time is displayed in days, hours, minutes, and seconds. By default, all down time is logged in the event log as unplanned. You can annotate the event log file to specify that down time is planned using the samlog -i evid -p PLANNED command.
up time%
The percent of time the object was up.
last state
The last logged state of the object when the report ran. The state can be UP, DOWN, or GONE. The UP and DOWN states are placed in the event log file by SAM. The GONE state must be added with the samlog command, and stops SAM from accumulating down time for an object. For example, if you remove a node from the cluster, SAM considers it down. When you mark its state as GONE, SAM stops accumulating down time for it.
