Trigger Specification
This specification describes the huawei-cloudeye trigger that scales based on a Huawei Cloudeye.
triggers:
- type: huawei-cloudeye
metadata:
namespace: SYS.ELB
metricName: mb_l7_qps
dimensionName: lbaas_instance_id
dimensionValue: 5e052238-0346-xxb0-86ea-92d9f33e29d2
targetMetricValue: "100"
minMetricValue: "1"
Parameter list:
namespace- Namespace of the metric.The format is service.item; service and item must be strings, must start with a letter, can only contain 0-9/a-z/A-Z/_, the total length of service.item is 3, the maximum is 32.metricName- Name of the metric.dimensionName- Name of the metric dimension.dimensionValue- Value of the metric dimension.targetMetricValue- Target value for your metric.minMetricValue- Minimum value for your metric. If the actual value of the metric you get from cloudeye is less than the minimum value, then the scaler is not active.metricCollectionTime- Collection time of the metric in seconds. Equivalent to the earliest start time of the end time. (default: 300)metricFilter- Aggregation method of the metric. (Values:average,max,min,sum, Default:average, Optional)metricPeriod- Granularity of the metric in seconds. (Default: 300, Optional)
Authentication Parameters
You can use TriggerAuthentication CRD to configure the authenticate by providing a set of IAM credentials.
Credential based authentication:
IdentityEndpoint- Identity Endpoint.ProjectID- Project ID.DomainID- Id of domain.Domain- Domain.Region- Region.Cloud- Cloud name. (Default:myhuaweicloud.com, Optional)AccessKey- Id of the user.SecretKey- Access key for the user to authenticate with.
The user will need access to read data from Huawei Cloudeye.
