Global Network Health Alert

The Global Network Health alert is included by default in CoPilot. It monitors the virtual machines of all your Aviatrix Gateways and triggers an alert when the virtual machine of any gateway meets the configured conditions.

The default settings include the following:

  • The default trigger condition for this alert is 75 PPS. More than 75 packets exceed the maximum for the instance type that are processed (bidirectionally) by the Aviatrix gateway per second. The Limit Exceeded Rate (PPS) metric is monitored. The default trigger condition can be modified.

  • The Aviatrix gateway is in a down status. The Gateway Status metric is monitored.

When the alert triggers, the event is listed in CoPilot on the Monitor > Notifications > Alerts page. In the Alerts page, search on Global Network Health to see the number of times by date the alert type was triggered.

It is recommended to upgrade the size of virtual machines if Aviatrix platform global health alerts are triggered frequently.

You can customize the configuration or configure CoPilot to send a message to a notification channel (email or webhook) of choice when this alert is triggered. See Configuring the Global Network Health Alert.

If the Global Network Health alert is triggered often, you may need to increase the size of the virtual machine running the gateway that triggered the alert.

Configuring the Global Network Health Alert

The Global Network Health alert is configured in CoPilot as a default alert. You can modify the alert, but you cannot delete the alert configuration.

You can also configure CoPilot to send a message to a notification channel (email or webhook) when this alert is triggered.

  1. Go to the CoPilot > Monitor > Notifications page and click on Alerts Configuration.

  2. In the Search box, type Global Network Health to quickly locate the relevant row in the table list and click the pencil icon in the row.

  3. In the Edit Alert dialog, do any of the following:

    • Change the OR operator if needed. By default, the alert triggers when any individual condition is met (Matches any condition (OR)). If you want the alert to trigger when all conditions are met, change the operator to Matches All Conditions (ALL).

    • Change the condition threshold of the Limit Exceeded Rate (PPS) metric. This is the number of packets per second that exceed the maximum for the instance type that are processed (bidirectionally) by the Aviatrix gateway. The condition threshold for packets per second can be any positive number.

    • Change the Evaluation Period CoPilot uses for triggering the alert. The period is the duration of time (in minutes) where CoPilot evaluates the average of the metric(s) specified to trigger the alert. When the average value is outside the ideal operating range of your conditions, CoPilot will trigger the alert. The higher the number, the more data points CoPilot includes in the average calculation.

    • Set or change the recipients (email or webhook channels) of notification messages for the alert.

    • Specify whether to send a separate notification message for each gateway that met the alert condition. If this option is off, CoPilot sends one notification message showing all gateways that met the alert condition.

    • (Reset to Defaults) Revert to default configuration values if you decide not to customize the alert’s configuration.

  4. Click Save.

CoPilot automatically resolves this alert when the alert metric(s) no longer meets the condition to trigger the alert. CoPilot resolves this alert only if the Limit Exceeded Rate (PPS) metric on the affected Gateway virtual machines do not meet the conditions any longer.
