Performance

Exercise 1: Accessing Device Performance Data​

Objective: Learn how to access real-time performance data for a specific device.

  1. Search for Device: Enter the name of a device (e.g., atl-edge-fw01) in the search bar and press enter.
  2. View Device Health: In the device card, find the dropdown labeled "Device health as of {time:Date}" and click it to view current health metrics.

Exercise 2: Analyzing Trend Data​

Objective: Examine performance trends over specified periods.

  1. Select "See Charts": From the device card, choose "See charts" to review performance trends over the last day or 7-day period.

Exercise 3: Evaluating Interface Performance​

Objective: Access and analyze performance data for specific interfaces.

  1. Navigate to Interfaces: Return to the device card, click on "Interfaces," and select an interface (e.g., gi0/0).
  2. View Interface Health: Click the dropdown labeled "Interface Health" to see the latest metrics.

Exercise 4: Reviewing Trend Data for Interfaces​

Objective: Explore performance trends for interfaces over time.

  1. Choose "See Charts": Select "See Charts" to examine performance trends for the chosen interface over the past day and 7-day periods.

Exercise 5: Path Search for Health Data​

Objective: Integrate health and performance data with path search functionality.

  1. Input Search Criteria: Use the search bar to enter criteria from a previous exercise.
  2. Select Device: In the path results, choose a device and open the "Device Health" dropdown to view health metrics and charts.

Objective: Analyze interface health within the context of path search results.

  1. Locate Interfaces: In the L3 section, find ingress/egress interfaces and select an egress interface (e.g., gi0/1).
  2. Analyze Performance Data: Click "See charts" to review performance data over time.
