APM Insight Dashboard


Overview

Applications Manager provides a primary set of application performance metrics such as response time, CPU utilization, disk, and memory utilization, error states, etc. These metrics will help you to keep track of the efficiency of applications, during regular intervals. You can also find the number of applications that are active, down, and unmanaged. Attributes like Availability, Application name, Agent type, APDEX score, Errors, Throughput, Fatal count, Avg. Response time etc.. can be viewed and managed either in tabular or grid view.

The performance metrics of the applications being monitored in APM Insight are displayed under the APM tab. These metrics include mainly:

  • Application Performance Index (APDEX)
  • Response Time
  • Throughput, etc.

Configure Alarms

  • In APM, the 'Monitor actions' dropdown->'Configure Alarm' option is supported at the Instance level (and not the Application level) and is provided on the Instance page so that we can use it to configure Threshold and Actions.

    Note: In APM Insight versions 16430 and below, the 'Actions' dropdown->'Configure Alarm' option is supported at the Instance level (and not the Application level) and is provided on the Instance page so that we can use it to configure Threshold and Actions.

  • By default, for the Availability and Health attributes, we fetch average data for the last 5 minutes while applying a threshold every minute. For other attributes, we fetch average data for the last 5 minutes while applying a threshold for 5 minutes.

    Note: In APM Insight versions 16560 and below, the average data for the last 5 minutes is fetched while applying a threshold for the respective attributes by default. Users can update the 5 minutes interval in the apminsight.properties file under <Applications Manager Home>\working\apminsight\conf directory (Key Name: attribute.update.timeinterval). Restart is required to apply these changes.

Enable Reports

  • In APM, the the 'Monitor Actions' dropdown->' Enable Reports' option is also supported at the Instance level (and not the Application level) and is provided on the Instance page so that we can use it to enable/disable reportsfor APM Insight attributes.

    Note: In APM Insight versions 16430 and below, the Actions' dropdown->' Enable Reports' option is also supported at the Instance level (and not the Application level) and is provided on the Instance page so that we can use it to enable/disable reports for APM Insight attributes.

  • By default, reports are enabled for all APM Insight attributes (under Setting → Enable Reports → Custom Reports → Set Monitor Type to APM Insight) and can be customized based on the requirement. Following is the list of reports that can be generated for APM Insight attributes:
    • Trend Analysis Report
    • At a Glance Report
    • Forecast Report
    • Inventory Report
    • Schedule Reports
    • Availability Report
    • Health Report
    • Attributes Report

Note: Common time zone should be maintained between the Applications Manager server and APM Insight agent-installed server for proper functioning.
