Monitor Device Level Information

 

You can view the following device information and device level statistics for the past 1 hour, 8 hours, 1 day, 1 week, and 1 month in the Overview tab of the Device-Name page:

  • Port Link Status—Represents the number of links that are up and down in the switch as a Donut chart.

    Mouse hover over the chart to view the number and percentage of links that are up and down; see Figure 1.

    Click the More Details link to view the Ports tab.

  • Recent Alarms—Lists the recent critical, major, and minor alarms generated on the switch; see Figure 2.

    Click the View All Alarms link to view information about all the alarms, on the Alarms page.

    See About the Alarms Page for more information.

  • Details—Displays generic details, such as serial number, management IP address, OS version, and device template used to configure the switch.

  • Resource Utilization—Displays the percentage of memory and CPU utilized in the switch for the selected time span; see Figure 3.

    CPU utilization is displayed for the following processes—user, background, system, interrupt, and idle.

    Note

    The CPU user process indicates the percentage of time that the CPU is handling user operations.

  • Top Ports by Input Bandwidth—Displays the top 10 ports on which the incoming packets consume the maximum bandwidth.

  • Top Ports by Output Bandwidth—Displays the top 10 ports on which the outgoing packets consume the maximum bandwidth.

  • Top Ports with Input Errors—Displays the top 10 ports with the highest number of errors in incoming packets.

  • Top Ports with Output Errors—Displays the top 10 ports with the highest number of errors in outgoing packets.

  • Top Ports with Input Packet Loss—Displays the top 10 ports that drop the highest number of incoming packets.

  • Top Ports with Output Packet Loss—Displays the top 10 ports that drop the highest number of outgoing packets.

  • Licenses—Displays details of licenses (such as license name and description) installed on the switch.

    Click the More Details link on this pane to view additional information about the licenses, on the Device License Files page.

    See About the Device License Files Page for more information.
