for the cluster. You can specify a time period for the statistics,
and
you can update the statistics by clicking the Update View button.

Information Displayed
The summary screen displays the following identifying information:
- Cluster name
- Current time
- Reporting period, including the years, days, hours, minutes, and seconds covered by the report
- Period begin and end dates
- Log format version
- Times of first and last events in the report
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.
