Metrics Monitored for Aviatrix Resources
The system metrics and network metrics that you can access in CoPilot are captured by the Aviatrix Controller. The Controller pulls the data from virtual machines (instances/hosts) that Aviatrix Gateways run on and feeds that data to CoPilot.
Some metrics can be used for triggering actions such as alerting and Gateway scaling. You can also use metrics to monitor the performance of Gateway hosts. You can monitor performance in CoPilot from the Monitor > Performance page.
In addition, with the Aviatrix Network Insights API add-on license, you can use APIs to analyze the performance and health of your Aviatrix-managed resources in external monitoring systems. See Monitoring with Network Insights API for information about using Network Insights Metric and Status APIs.
About Metrics that are Monitored for Aviatrix Resources
Aviatrix Controller captures system metric and network metric information about the virtual machines (instances/hosts) that Aviatrix Gateways run on.
Health-type metric information is also captured for Controller and CoPilot virtual machines. See Global Control Plane Health Alert.
Metrics that are monitored by Aviatrix Controller and Aviatrix CoPilot include the following:
On the CoPilot Monitor > Performance page, you can select metrics to monitor performance on your resource VMs.
On the CoPilot Monitor > Notifications > Alerts Configuration page, you can configure how to use the pre-existing set of metrics to send notifications about events that occur in your network, such as performance bottlenecks or other problems.
To better understand how notifications and alerts work and how to configure them in CoPilot, see documentation:monitoring-troubleshooting:user-alerts-network.adoc.
For more information about integrating Aviatrix metric and status APIs with external monitoring tools, see Monitoring with Network Insights API.
Health Metrics for Triggering Notifications or Other Actions
The following health metrics are available in CoPilot. They are listed in alphabetical order, by the name used in the CoPilot UI.
| Name (Health Metric) | Description | Internal Metric Name | Accessible by API |
|---|---|---|---|
BGP Peering Status |
Any BGP peering status change triggers an alert. |
BGPpeeringStatus |
|
Connection Status |
Any connection status change on the specified gateways/connections triggers an alert. |
ConnectionStatus |
|
Gateway Status |
Any gateway status change triggers an alert. |
GatewayStatus |
|
Underlay Connection Status |
Monitors the syslog from any connection that includes the host as the source or destination. When syslog data indicates a potential problem from each direction of the connection between that host and another host within 30 seconds of the other, the alert is triggered. On the same connection, if the syslog data later indicates the problem is resolved from either direction, the alert is automatically resolved. |
