You must configure the Service Monitor widget before you
use it. The widget has a General Graph Settings tab
for specifying things like refresh rate and graph time length and
a Monitored Service Operations tab for specifying
what you want to monitor and how you want it to be displayed.
Procedure
- Log on to Business Space and open the Service Monitor widget.
- Click Edit Settings from the widget
menu.
- Specify general graph settings in the General
Graph Settings tab, as follows.
- Graph refresh time interval: The rate the
response time and throughput graphs refresh, measured in seconds.
Clear the check box if you do not want the graph to refresh automatically.
- Graph time length: The period of time you
want to plot operations on the graph, measured in hours or minutes.
This value forms the X-axis (elapsed time) on both the Response Time
and Throughput graphs. By default, each graph plots five minutes of
data. The value you select here affects the value in the Cumulate
measurements by field; selecting a graph time length of
minutes causes measurements to be cumulated in seconds, while a graph
time length of hours causes measurements to be cumulated in minutes.
- Cumulate measurements by: The unit of time
(seconds or minutes) used to measure cumulative statistics like mean,
minimum, and maximum. The unit of time is determined by the value
you specified in the Graph time length field.
All response times and throughput are cumulated over a second or a
minute and that cumulated data is plotted on the graphs When you select
minimum, maximum, or mean for an operation, the graphs plot the corresponding
statistic over the unit of time you specify here.
- Response time Y-axis limit: A positive
integer that sets the highest response time to plot on the graph.
This is an optional configuration parameter.
- Throughput Y-axis limit: A positive integer
that sets the highest throughput value to plot on the graph. This
is an optional configuration parameter.
- Show statistics: The option to display
operation statistics, including the cumulated statistics over the
last second or minute and since monitoring began. If you select Show
statistics, the Statistic Measurements table displays
this information below the graphs.
- Use the Monitored Service Operations tab
to define which operations to monitor and how to present the monitoring
data, as follows.
- If the operation you want to monitor is not listed on
the tab, click Add new operation to monitor and
select the operation or operations from the Select operations to add
dialog box.
- Choose a line color for each operation plotted on the
graphs. When you are plotting multiple operations, using different
colors can help you distinguish between the various operations.
- To monitor response times for an operation, use the Response
Time menu to indicate the statistical measurement you
want to plot (maximum, minimum, or mean). Optionally, specify a threshold
value for response times.
- To monitor throughput for an operation, select the Throughput check
box. Optionally, specify a threshold value for throughput.
- Click Save to save your configuration.
