Alerts

This page allows the user to view and manage different types of alerts encountered by the appliance.

 

 

The alerts are generated whenever there is a hardware change, the system is nearing its maximum available capacity, the cloud is unreachable for a certain length of time or if the system software is being upgraded.

An alert will be displayed as a banner message in red text across the top of the page. Based on their severity, the alerts can be 'information', 'warning' or 'critical'. There is also a status indicator icon at the top right of the 'Alerts' page. The color of the icon is yellow or red depending upon whether the status of any hardware component in the appliance is yellow (recovering) or red (failed or degraded) in the 'Hardware' page. The banner message presents three options to the user; acknowledge, view or configure each leading to a different set of actions. Each of these three options is discussed below:

 

  1. Acknowledge - Clicking on 'Acknowledge' will present the following confirmation dialog to the user -

    Select OK to proceed. The banner message will change to 'Alert acknowledged' and disappear.

 

  1. View - Clicking on 'View' will display all the alerts related to that specific condition to the user. For instance, in the screenshot below, the warnings triggered in response to 'Cloud being unreachable' are shown to the user along with their start date, time, severity, summary and whether or not those were explicitly acknowledged by the user.

  1. Configure - Clicking on 'Configure' will direct the user to the 'Alert Settings' screen where the user can configure the settings pertaining to alert in question. The details of how to configure the alert settings are in the 'Alert Settings' page.

 

In general, the alerts persist until these are acknowledged by the user or the user has removed the condition that caused the alert in the first place. The alerts that are acknowledged will be cleared and moved to the 'Cleared Alerts' tab.

The 'Alerts' page has tabs at the bottom of the tabular view that can be used for navigating between pages. There is also the option of specifying the number of rows per page by choosing either 10, 20, 50 from a drop-down list in the 'Page Size' field. Additionally, the user can refresh the view by clicking the refresh icon Refresh.png. The user can also export a log of alerts by clicking the CSV icon CSV.png into a tab-delimited file that be opened with a spreadsheet application for further parsing.

The user actions in response to alerts are also logged in 'Audit Logs' and can be viewed by the user.

This section discusses in detail the two tab views that are presented in the 'Alerts' page -

Active Alerts

This tab displays all the active alerts encountered by the appliance. The user needs to review the alert conditions.

These alerts can be filtered based on one or more of the following fields:

  • Alert - pertains to the type of the alert and can be chosen from a drop-down list. The user can choose from one or more of the following:

    •  All - this is the default setting and when chosen, displays all the alerts.

    • Hardware Status - this alert is raised when the hardware state of any of the components in the appliance is changed since the last time it was checked. The condition is evaluated every 1 minute. This alert is not present on the Virtual Appliance.

    • Host Capacity Consumption - this alert is raised when the provisioned/used capacity is exceeding certain defined thresholds such as 50%, 65% or 80% of the maximum host capacity. The condition will be evaluated daily. The alert continues until the utilized capacity falls below the defined threshold (80% of maximum host capacity). If the user exceeds the available capacity, then either data has to be removed or additional licenses have to be purchased.

    • Cloud Access - this alert is triggered when the cloud is unreachable for greater than 5 minutes at any given instance.

    • Upgrade Status- this alert is triggered when an upgrade is in progress.

    • Appliance Restart - this alert is raised when an appliance has restarted. The restart could be user-initiated or subsequent to a failover.

    • Configuration Change - this alert is displayed when there has been a change in the configuration of the appliance. The alert serves as a reminder to the user to back up the appliance configuration. Note that if this alert persists for 7 days and the user has still not backed up the appliance configuration, the severity of alert increases from 'Warning' to 'Critical'.

 

  • Started on - filters by the time when the alert was first triggered.

 

  • Severity - the user can filter based on the severity of the alert. The severity can be 'Information', 'Warning' or 'Critical'.
    • Information - the alert is presented to the user for informational purpose only. No user action is required.
    • Warning - the alert is presented to the user as a warning in response to the change 
    • Critical - this alert is presented to the user when an immediate user action is required.

 

  • Acknowledged - the alerts can be filtered based on whether the user has acknowledged the alert or not. The field is set to false if the user has not acknowledged the alert by clicking on 'Acknowledge' option.

 

  • Summary - the active alerts can also be filtered based on a user-specified string.

 

Checking the 'Acknowledge All' option will allow the user to acknowledge all the alerts.

Cleared Alerts 

This view shows the alerts that were once encountered but since then the condition causing the alert has been removed. The alert conditions could be actually resolved by the user or resolved on their own. For instance, the license capacity alert may be cleared if the user deletes a volume.

The 'Cleared Alerts' can be filtered based on one or more of the following fields :

 

  • Timestamp - clicking on the field below 'timestamp' pops up a calendar view and allows the user to specify a range of time.

 

  • Host - the user can type in the 'IP address' or  the 'Name' of the appliance and filter the alerts based on that information.

 

  • Details - this field will filter the 'Cleared Alerts' based on a user-specified string.
