Introduction
Cloud service monitoring events generated on Tencent Cloud Observability Platform are important events that occur in the lifecycle and operation of various Tencent Cloud services and the underlying infrastructure and services. Tencent Cloud Observability Platform provides a centralized access for querying and statistically analyzing the events, which helps you associate resources and review exceptions, and supports your monitoring and OPS on the cloud.
Information sources of cloud service monitoring events are system logs and monitoring metrics of underlying service modules, which ensures the accuracy and value of the information.
Event Format
Taking a "ping unreachable" event generated by CVM as an example, the standard format for delivering the event to EventBridge is as follows:
{
"specversion":"1.0",
"id":"13a3f42d-7258-4ada-da6d-023a333b4662",
"source":"${ProductName}.cloud.tencent",
"type":"cvm:ErrorEvent:ping_unreachable",
"subject":"${resource ID}",
"time": 1615430559146,
"region":"ap-guangzhou",
"resource":[
"qcs::eb:ap-guangzhou:uid1250000000:eventbusid/eventruleid"
],
"datacontenttype":"application/json;charset=utf-8",
"tags":{
"key1":"value1",
"key2":"value2"
},
"status":"1",
"data":{
"appId":"1250000011",
"instanceId":"ins-sjdksjk",
"projectId":"11",
"dimensions":{
"ip":"127.0.0.1"
},
"additionalMsg":{
"IP":"something unnormal"
}
}
}
Event Sources
Based on event information sources, causes, characteristics, and forms, cloud service monitoring events are divided into two categories:
Events generated by resource instances and products (such as CVM instances) that are purchased and used by customers in Tencent Cloud. These events are directly or indirectly triggered by customers during use. They belong to specific resource instances. Customers can control and manage them. Resource instances affected by and associated with events can be explicitly determined.
Events generated by the underlying platform infrastructure and services that support Tencent Cloud services, such as Virtual Machine Manager (VMM) that supports CVM at the virtualization layer and the underlying physical machines, networks, and storage modules. These events are generated or caused by the infrastructure and services of Tencent Cloud, and are not the result of customer behavior. They belong to services. Customers cannot control events, which instead can only be handled by Tencent Cloud. Services or product modules affected by and associated with events can be determined, but the affected and associated resource instances cannot always be determined.
Event List
The following table describes cloud service monitoring events generated by the underlying platform infrastructure and services.
|
| | CVM infrastructure storage module | The I/O performance of the CVM instance decreases, and data read/write exceptions occur. |
| CVM network connection issue | CVM infrastructure network | The speed of the CVM instance network slows down, or the network is disconnected. |
| | | The CVM instance bears a high load or crashes, causing service unavailability. |
