The Performance Manager displays performance statistics collected during a specified interval for an attribute selected from the list of Monitored Attributes on the Performance Manager window.
To open the Performance Manager screen:
Step 1 From the pop up menu available on the selected OC3 port, DS3 port, or ADSL port, select Open Performance Manager. The Performance Manager screen appears:
The Performance Manager screen has three tabs:
The information displayed on each tab is as follows:
The Line Chart tab displays a graph (shown in Figure 9-1) with the retrieved data. The X-axis depicts the time at which the polling was done. The Y-axis depicts the value retrieved or the value when the equipment did not respond properly.
Further information regarding the units, attribute and summary rule are provided using appropriate color coding at the top of the chart. Blue represents the values retrieved and red identifies any polled values missed.
The information on this tab is shown as a Bar Chart with the retrieved data.
This tab displays the data retrieved in a tabular format. The first column shows the Time of polling and the second column shows the retrieved values.
To view performance statistics select:
Step 1 Open the Performance Manager. The window shows the name of the selected object.
Step 2 From the Monitored Attributes list select the attribute that has to be monitored.
Step 3 In the Start Date entry boxes, enter the date on which you wish to begin viewing performance data. The format must be mm/dd/yyyy.
Step 4 You set a start time and an end time using the 24 hour notation. The times are inclusive. In the Start Time data entry boxes enter the time that the view of the performance statistics has to start on the Start Date.
Step 5 To set the End Date you have two options:
In the End Date entry boxes, enter the date on which you wish to stop viewing performance data. The format must be mm/dd/yyyy
or
Select the Now checkbox to view the data from the selected start date to the current time. By selecting this option you will not have to update the end date and time fields.
Step 6 To set the End Time you have two options:
In the End Time entry boxes, enter the end date on which you wish to stop viewing performance data
or
Select the Now checkbox to view the data from the selected start date to the current time. By selecting this option you will not have to update the end date and time fields.
Step 7 From the drop down list select the Summary Interval rule to be used. This will vary according to the attribute selected and is the period of time over which the rule is applied. The option to select raw is always available and which will display performance data in its most detailed format, i.e. not summarized.
Step 8 From the drop down list select the Summary Rule to be used. This gives you the option to summarize data in greater detail as follows:
totals all values gathered in the summary period
takes the average of all values gathered in the summary period
presents the lowest value received over the summary period
presents the highest value received over the summary period
will display either 1 or 0. This is typically used for status flags. Some attributes may have only two potential values, e.g. True or False; Yes or No; 1 or 0. When summaries are generated from values such as these and the logical OR rule is used, the summarized value is 1 if any value in the summary interval is 1. If all values in the summary interval are 0, then the summarized value is 0.
Step 9 Select the Refresh button.
Step 10 By default a line chart of the performance information to date will be displayed. You can view performance information in the following formats
Step 11 The performance information displayed will correspond to the attributes raw values. If a summary period is selected the information will be displayed according to the summary rule. No summary period is associated with raw data.
Step 12 Performance Manager graphs and charts also indicate when an attribute started and stopped being polled due to history storage criteria being added, edited or removed. Start and Stop polling events are shown in charts and tables:
