Configure Thresholds and Alerts

You can add a threshold configuration and gets alerts for the configured threshold.
To configure the analytics-associated thresholds and alerts:
  1. On the Home page, in the left navigation pane, click
    Analytics
    Thresholds
    Add
    .
    The
    Threshold - Add configuration
    page opens.
  2. In the
    Name
    text box, enter a unique name for the configuration.
  3. From the
    Scope
    drop-down menu, select the entities that are to be considered for analysis. For example the entities can be VMs, Flows, etc.
    1. To identify a subset of entities that are to be considered for analysis, enter one or more criteria in the
      Select criteria
      text box.
  4. In the
    Condition
    section, set a condition to create an alert.
    Based on the condition you set, the system decides if the threshold is violated.
    1. In the
      aggregared over
      text box, select the grouping of the entity. You can set a threshold on a cumulative metric by aggregating the data over a group of entities.
    2. In the
      when
      text box, enter the value for which you are checking the threshold.
    3. Configure a static or a dynamic threshold.
      • To configure a static threshold, select either of the following threshold conditions from the list:
        • exceeds threshold
        • drops below
        • is outside range
      • To configure the dynamic threshold, select
        deviates from the past behavior
        . Select the sensitivity based on your requirement of reporting.
    4. Enter the upper bound and lower bound range.
      When you enter the
      Upper Bound
      or the
      Lower Bound
      range, ensure that you enter the value based on the unit of measure for the selected condition. The following conversion values are for your reference:
      • 1 Kbps= 1000 bps
      • 1 Mbps= 1000 kbps
      • 1 Gbps = 1000 mbps
      • 1 KB=1024 B
      • 1 MB=1024 KB
      • 1 GB = 1024 MB
    When you set the threshold, you can view the associated graph at the top of the page. The pink bar denotes the VMs or the flows violating the threshold. You can view the list of the entities that have violated the threshold and the entities that are within the threshold in the system.
  5. From the
    Minimum Violation Duration
    drop-down menu, select a time duration after which
    VMware Aria Operations for Networks
    should trigger alerts if the violation lasts longer than the selected time duration.
    For example, If you set
    Minimum Violation Duration
    as 15 minutes, you get alerts only if the violations stays active over 15 minutes.
  6. Configure the severity of the alert.
  7. In the
    Notification
    section, configure when and who can receive notifications.
    Select
    Send SNMP Trap
    only if you have configured SNMP traps on your system.
  8. Click
    Submit
    to create the threshold configuration.
