)1. 架构关系图
?
集群架构通常可以通过图来表征，其中节点表征组件，边表征交互关系，通过图结构可以直观把握集群的架构，形如下图：
?
可通过形如下的数据结构描述：
{
"nodes": [
{
"_id": "0ce0e913f6e5516846c654dbd81db6ecab1f684e",
"name": "kube-apiserver",
"description": "XXX VPC 内",
"type": "managed component",
"dependencies": {}
},
{

"name": "etcd",
"description": "XXX VPC 内",
"type": "managed component | storage",
"dependencies": {}
},
{

"name": "eni-operator",

}
},

"description": "访问阿里云 ECS OpenAPI，管理 VPC/VSwitch 等网络资源"
}
]
}

)2. 架构运行图
?
集群运行过程中，组件及交互关系可以通过外部观测数据推测内部状态，如 log/metrics/trace。与集群架构图结合，可以在静态架构的基础上叠加动态的洞察数据，更直观把握集群的健康状态，如下图：
?
其中的数字表征洞察数据，可以是「异常数量」「请求流量」等。除了通过数字进行洞察，还可以使用「颜色表征健康状态」「线条粗细表征流量大小」等。
可通过形如下的数据结构描述：
{
"nodes": [
{
"_id": "ea4538dc0625d06b0dc93579998e04288656050f",
"name": "mutatehook",
"deploy": {
"type": "K8s:Deployment",
"namespace": "kube-system",
"replicas": 3
},
"insight": [
{
"source": {
"vendor": "cloud:aliyun:sls",
"log_project": "xxx",
"log_store": "mutatehook",
"log_url": "https://sls.console.aliyun.com/lognext/project/xxx"
},
"signal": {
"exception": {
"fuzzy": "fail OR Fail OR error OR Error"
}
}
}
]
}
],
"edges": [
{
"_id": "38bce9ca8a0cec6d8586d96298bd63b0523fc946",
"source": "eni-operator", "target": "kube-apiserver",
"insight":[
{
"source": {
"vendor": "cloud:aliyun:sls",
"log_project": "xxx",
"log_store": "xxx",
"log_url": "https://sls.console.aliyun.com/lognext/project/xxx"
},
"signal": {
"exception": {
"unauthorized": "Unauthorized",
"throttling": "'Throttling' OR 'throttling'"
}
}
}
]
}
]
}

)3. 资源构成图
资源管理是个复杂的话题，通过分析集群中资源的构成关系，也可以尝试通过图结构来表征集群的资源构成，节点表征资源，边表征资源的从属或绑定关系。
?
可通过形如下的数据结构描述：
{
"kinds": ["vpc", "vswitch", "securitygroup", "ecs", "clb", "rds", "nat", "eip"],
"tags": {
"cluster/product": "xxx",
"cluster/id": "2736f42d4e882ad6825d6364545a3f1cb5136859",
"cluster/name": "xxx",
"cluster/env": "staging"
},
"nodes": [
{

"nodes": [

)4. 资源运行图
?
资源使用过程中，也可以对资源及资源间的关系通过外部观测数据推测内部状态，如 log/metrics/event。与资源构成图结合，可以在静态资源的基础上叠加动态的洞察数据，直观把握集群资源的使用状态。
