Regularly collecting performance data allows you to baseline systems, perform capacity planning, see bottlenecks and immediately recognize unusual resource demands. ELM includes a built-in feature for collecting performance data from Windows systems and stores it in a database. Without using local resources on the systems being monitored, ELM can aggregate and chart the data through the ELM Editor reporting engine. This is a powerful yet easy way to proactively manage system resources.
In the ELM Console, the Reporting container has a Performance Table sub-container with nodes for all the configured performance objects and counters. You can have Performance Collectors that contain different groups of counters, or a single Performance Collector that contains all of the counters you want to collect. In previous versions of ELM you could see all performance objects listed here whether they were were active (contained data) or not. Depending on the size of your environment and the scope of performance monitoring you are doing, this can be overwhelming with potentially dozens of performance objects listed, some containing no data.
By default, ELM shows only Active Performance Data – those performance counters with collected data. So if you have been adding Performance Counter Definitions and are wondering why the performance object groups are not showing up in the Performance Tables container, they may actually be there, but are not displaying because they have no collected data yet.
To view all assigned performance counters, simply right-click the Performance Tables container and select Show All in the context menu.
This will expand the Performance Data sub-container and show all performance objects the ELM Server knows about. This “library” of counters can then be assigned to collect data with either a Performance Collector Monitor Item or watch levels with a Performance Alarm Monitor Item.
When showing all, ELM will now specify if a performance object does not have data by tagging the end of the container name with [No data]. This is a very helpful quick point of reference so that you can update collection intervals and schedule reports accordingly based on the performance data you want to trend over time.
Performance monitoring is available in ELM Enterprise Manager System, Core and Performance licenses.
