As opposed to plug-in-based monitoring: With Agent-based (zero-configuration) infrastructure monitoring, many Measures are available out of the box. In addition to simplifying the configuration process (you don't need to set up passwords or permissions, especially for Windows), retrieving measurements from hosts now has less impact on the system's performance.
The target host must have at least one active and connected Agent installed.
If you migrate AppMon from a release earlier than 4.2, you should review existing configurations of Windows Performance Monitor and Unix Monitor plugins, and remove them if the Measures that are collected by the Agent are sufficient. See Plugin vs. Agent-based Measures for a table of equivalent Measures.
If you need to install and configure a Host Monitoring Agent because there is no other active Agent on the machine, refer to Host Monitoring Agent for details.
Besides supporting pre-configured Monitoring in Application Overview Dashboard and dashboards, Agent-based Measures can be used to build custom charts and dashboards. Use the Measure Picker dialog box, as shown below.
- Create a new Chart dashlet:
- AppMon 2017 May In the Cockpit, expand the Charting node and double-click Custom.
- AppMon 2018 April In the sidebar, click Dashlets > Chart.
- Double-click the Add Series button to open the Measure Picker dialog box.
- Expand the tree as needed to display the desired Measure, then double-click the Measure to list it in the Add Measures to Chart area.
- Click Add to add the Measure.
- Repeat steps 3 and 4 as needed, then click Close.
Plugin vs. agent-based measures
It is recommended that you use Agent-based Measures whenever possible.
In the table, Agent-based Measures that are not subscribed by default are marked with an asterisk (*).
|Windows Performance Monitor||Unix Monitor||Agent-based Monitoring||Notes|
