Creating custom service or component alarms

Customizing alarm settings enables you to create a customized methodology for monitoring the StorageGRID Webscale system. You can create alarms on individual services or components in addition to creating global alarms.

Before you begin

  • You must be signed in to the Grid Manager using a supported browser.
  • To perform this task, you need specific access permissions. For details, see information about controlling system access with administration user accounts and groups.

About this task

You should not change Default alarm values unless absolutely necessary. By changing Default alarms, you run the risk of concealing problems that might otherwise trigger an alarm

Steps

  1. Select Support > Grid Topology.
  2. Select a service or component in the Grid Topology tree.
  3. Click Configuration > Alarms .

    Configuration > Alarms page
  4. Add a new row to the Custom alarms table:
    • Click Edit edit icon (if this is the first entry) or Insert insert icon to add a new alarm.
    • Copy an alarm from the Default alarms or Global Custom alarms tables. Click Copy copy icon next to the alarm you want to modify.

    Severity The icon and text indicating the level of the alarm.
    Message The reason for the alarm (connection lost, storage space below 10%, and so on).
    Operator Operators for testing the current attribute value against the Value threshold:
    • = equal to
    • > greater than
    • < less than
    • >= greater than or equal to
    • <= less than or equal to
    • ≠ not equal to
    Value

    The alarm’s threshold value used to test against the attribute’s actual value using the operator.

    The entry can be a single number, a range of numbers specified with a colon (1:3), or a comma delineated list of numbers and/or ranges.

    Additional Recipients A supplementary list of email addresses to be notified when the alarm is triggered, in addition to the mailing list’s configuration on the Configuration > Notifications page. Lists are comma delineated.
    Note: Mailing lists require SMTP server setup in order to operate. Before adding mailing lists, confirm that SMTP is configured.
