As an APM administrator, use Metric View for a clear overview of agent metric values. Investigate agents to see their metric values for a certain time range.

Overview
APM offers two Metric Views:
  • Global Metric View
    contains all metrics from all agents that are connected to the APM infrastructure.
  • Contextual Metric View
    shows a subset of metrics that are relevant to the selected components in the map.
Both Metric Views contain a Metrics Tree that lists metrics and other information in a tree format. Metrics are organized in a 
Host|Process|Agent
 hierarchy. 
Understand the Metrics Tree
The highest level in the tree represents application server hosts. The second level represents processes. The third level represents agents that are installed on individual application server hosts. The tree view of agents, resources, and metrics refreshes every 15 seconds to show current metric data.
Custom Metric Host (Virtual)
 - This node represents a virtual host that contains metrics that a specific agent did not report. For example, aggregated metrics appear under this node. This node does not correspond to a physical host computer.
Hosts
 - This node represents a computer that hosts an agent. Each host node contains a process node for the instance of the monitored application. Process nodes in turn contain agent nodes. Nodes that correspond to application and system resources and contain metrics are stored in the agent nodes. The application resources in the agent nodes differ based on the agent type (Java or .NET).
The high-level node represents the following components:
  • Components of your J2EE or .NET application, such as servlets, EJBs, or ASP pages
  • System nodes, including the host running your app server and the host computer running CA APM
View an Agent Metric in the Global Metric View
View live data or select a range of time to view historical data. Compare, correlate, and visualize the metric values for a specific time range.
Follow these steps:
  1. In APM, click
    Metric View 
    in the left pane to open the Global Metric View.
    The Metrics Tree opens.
     
  2. Select an application server host.
  3. Drill down further in the tree and click the agent node that you want to investigate.
  4. Click on a folder in the metrics tree to view the
    Metric Overview.
    The
    Metric Overview
    contains a pie chart summary, metric counts, and percentages for the metrics that are in the individual subfolders of the selected folder. Click on a metric in the pie chart or table to open the relevant sub-folder.
  5. (Optional) Use 
    Search metrics
     to find specific metrics in the Metric Tree. 
  6. (Optional) To hide metrics that do not report any current data to the agent, right-click the agent node and click
    Hide grayed out metrics
    .
    The metric does not appear in the Metric tree.
    The Metrics Tree shows the metric again after the agent starts receiving current data from the metric.
  7. Click on a
     
    metric, for example, 
    Average Response Time (ms)
     to view its values in the metric chart. You can select multiple metrics from the Metrics Tree for comparison in the metric chart.
    The Metrics Tree shows two types of metrics:
    • String metric
       - the value of the metric is a string. The metric chart only shows the current value at the end of the time range.
    • Numeric metric 
      - the metric chart shows minimum and maximum values
  8. Use the 
    Timeline
    to select a specific time range.
  9. Drag the pointer over the chart to zoom in to a shorter time frame. 
     The
    Timeline
    shows ranges within a minimum of 8 minutes and a maximum of 1 year. 
  10. Select the time range from the 
    Resolution
     drop-down list (15 minutes, 30 minutes, 1 hour, 2 hours, 6 hours, or 12 hours) to see values for the timeframe. The possible time range values are 15 seconds, 30 seconds, 1 minute, 2 minutes, 5 minutes, 15 minutes, 30 minutes, 1 hour, 2 hours, 6 hours, 12 hours, 1 day, 7 days, 30 days, and 1 year. 
    The time range values in the
    Resolution 
    drop-down list appear based on the selected time range on the
    Timeline
    .
  11. (Optional) In the top right corner of the chart, check
    Show Min/Max Display
    .
    The minimum and maximum values show in the chart. 
  12. (Optional) Share the URL with your colleagues so they can see the same view of the particular metric in the tree. 
Open the Contextual Metric View
Open the Contextual Metric View from the Map or Analysis Notebook to view a subset of metrics for a specific node in the map.
To open the Contextual Metric View from the Map, follow these steps:
  1. In APM, click 
    Map 
    in the left pane.
  2. In the map, select a node that you want to see the agent metrics for.
    If you select more than one node, the Metrics Tree shows a union of metrics that are relevant to the selected nodes.
  3. Click the 
    Metric Browser 
    panel to open the Metrics Tree.
To open the Contextual Metric View from the Analysis Notebook, follow these steps:
  1. In APM, click
    Experience View
    in the left pane.
  2. Find an
    Experience Card
    that you want to view metrics for and click 
    Open an Analysis Notebook
    .
    An Analysis Notebook and map appear.
  3. In the map, select a node that you want to see the agent metrics for.
    If you select more than one node, the Metrics Tree shows a union of metrics that are relevant to the selected nodes.
  4. Click the 
    Metrics Tree 
    panel to open the Metrics Tree.
