Monitor Items
Creating and Using Monitor Items
Monitor Items are individual items that you want to monitor or collect. For example, to collect
performance data from a Windows NT, Windows 2000, Windows XP or Windows 2003 computer, you
would use an Performance Collector. To monitor performance and be notified of potential problems, you
would use a Performance Alarm.
ELM Performance Manager includes several Monitor Items:
§
Agent Monitor. This is used to monitor an ELM Service Agent. Agent Monitors perform regular
heartbeat checks on Service Agents. If the Server Agent does not respond or is slow in
responding, a variety of actions and notification options can be triggered.
§
ELM Server Monitor. This is used to enable a Service Agent to monitor availability of the ELM
Server.
§
Performance Alarm. Performance Alarms monitor performance objects, counters and instances
and can generate a variety of Notification Methods when a counter or instance of a counter is
greater than, less than or equal to your specified threshold for your specified duration.
§
Performance Collector. This Monitor Item is used to collect and store performance data from
Windows NT, Windows 2000, Windows XP and Windows 2003. A Performance Collector is a
group of performance counters that are collected at the same time. You can use multiple
Performance Collectors that contain different groups of counte rs, or a single Performance
Collector that contains all of the counters you want to collect.
§
Process Monitor. If you need to monitor individual processes, you can do so with a Process
Monitor. The Process Monitor is multi-functional; it can let you know when a process has
exceeded the threshold of CPU usage you specify, and it can track when processes are
instantiated or terminated.
§
WMI Monitor. If you are using Windows Management Instrumentation--the Microsoft
implementation of Web-Based Enterprise Management (WBEM)--you can use WMI Monitors to
query a WMI namespace and database. If the results of the query change, a variety of actions
and notification options can be executed.
Some Monitor Items also include a checkbox for ‘Default.’ When checked, this monitor item will
automatically be assigned to any new (appropriate) Agents that you create.
