Performance Collector

Previous Next

Performance Collectors are sets of one or more performance objects, counters and/or instances that are grouped together for collection and aggregation. ELM Enterprise Manager is pre-populated with a variety of Performance Collectors. These can be edited or custom Performance Collectors can be created. Each Performance Collector has three parts: the counters to be collected; the frequency of the collection (e.g., every 30 minutes, every hour, etc.); and the days on which collection occurs.

Performance Counters

ELM is pre-populated with Performance Objects and Counters. If the required object, counter or instance is not listed, it can be added from a Windows computer that publishes the counter.

Summary

Performance data is summarized or aggregated by one of several statistical methods. Calculating an average is ELM's default method. Data aggregation is provided to help minimize database storage space requirements for collected performance data. Aggregated tables contain detailed data for the most recent collection period and summary data for previous collection periods.

•Data can be aggregated once a Week , once a Month , once a Quarter , or disabled (None).

•Use the When field to select the day of the week on which aggregation will take place.

•Use the At field to specify the time.

Note
Data aggregation maintains detail data for one aggregation period, calculated values for older data. This method provides detailed data for short-term reports, for example weekly reports. Summarized data is available for longer-term reports, for example quarterly reports.

Aggregation is not required by ELM. It can be disabled, or detailed data can be moved to the ELM Archive database.

Actions

Performance Collectors gather data, deliver it to the ELM Server, and if aggregation is enabled, minimize storage requirements. These events indicate the success of performing these tasks.

•Error 5600 - The ELM Server had trouble receiving the performance data.

•Error 5601 - The ELM Server had trouble aggregating the performance data.

•Informational 5602 - The ELM Server successfully aggregated the performance data.

Test Monitor

Test any Monitor Item against any Agent capable of running the Item using the drop-down and Test button on this dialog box. Testing a Monitor Item prior to putting it into production validates that the monitor item is configured properly. To test a monitor item:

1.Select the Agent you wish to test against from the drop-down list.

2.Click the Start Test button.

If the test was successful, you will receive a pop-up indicating this and the option to see detailed results of the test. If the test failed, detailed results of the test will automatically open in Notepad.

Schedule

Displays the Scheduled Interval and Scheduled Hours settings which control the frequency for the Monitor Item.

Scheduled Interval tab

Specify the interval at which the monitoring, polling or action is to occur. Depending on the Monitor Item type, Items can be scheduled in interval increments of Seconds, Minutes, Hours and Days. The Scheduled Interval is relative to the top of the hour or top of the minute. For example, if a Scheduled Interval is configured for 10 minutes, the Monitor Item will execute at hh:10:00, hh:20:00, hh:30:00, hh:40:00, hh:50:00, h1:00:00, etc. If a Scheduled Interval is configured for 15 seconds, the Monitor Item will execute at hh:00:15, hh:00:30, hh:00:45, hh:01:00, hh:01:15, etc.

Scheduled Hours tab

Select the days and/or hours this item is active. By default, the schedule is set to ON for all hours and all days. Mouse clicks toggle squares between ON and OFF. Clicking on an individual square will toggle the active schedule for that hour. Clicking on an hour at the top of the grid, or on a day of the week at the left of the grid will toggle the corresponding column or row. Keyboard equivalents are the arrow keys and the space bar.

Properties Tab

This read-only tab displays the properties of the selected object and the values for those properties.
