You can check Gateway Load Balancer (GWLB) monitoring metrics for the real-time usage and status of GWLB instances as well as potential risks, then promptly troubleshoot unhealthy instances and make sure that the GWLB service is running as expected.
Background information
To call the CloudMonitor API, you need to set the Namespace, Period, MetricName, and Dimensions parameters for your GWLB instance.
Set Namespace to
acs_gwlb.Period defaults to 60 (in seconds) and you can also set it to a multiple of 60.
Set Dimensions to a JSON string. Set the instanceId field in Dimensions to the ID of your GWLB instance. Example:
[{"instanceId":"gwlb-0jl04f66daa388ec****"}].
GWLB monitoring metrics
In the Dimensions column of the following table, some fields are described as follows:
addressIpVersion indicates the IP version that the GWLB instance supports.
For IPv4 instances, the field should be set to ipv4, and Dimensions should be set to the following:
[{"addressIpVersion":"ipv4"}].For dual-stack instances, the field can be set to ipv4, ipv6, or dualstack. For example, if the field is set to dualstack, Dimensions should be set to the following:
[{"addressIpVersion":"dualstack"}]. If the field is set to dualstack, the values of monitoring metrics indicates the sum of the IPv4 and IPv6 metric values of the GWLB instance.
availableZone indicates the zone ID of the GWLB instance.
To query the monitoring metrics of an GWLB instance in one of its zones, set Dimensions to a value similar to the following:
[{"availableZone":"cn-wulanchabu-a"}].To query the monitoring metrics of an GWLB instance in all its zones, set Dimensions to the following:
[{"availableZone":"all"}].
