stackstorm 18. 源码分析之----stackstorm表结构分析
1 查看stackstorm的mongodb中的表结构
1.1 查看mongodb的用户名和密码
StackStorm - /etc/st2/st2.conf
database.username - MongoDB database username.
database.password - MongoDB database password.
messaging.url - RabbitMQ transport url (amqp://
Mistral - /etc/mistral/mistral.conf
database.connection - PostgreSQL database connection string (postgresql+psycopg2://
transport_url - RabbitMQ transport url (rabbit://
参考: https://docs.stackstorm.com/install/rhel7.html#install-webui-and-setup-ssl-termination
1.2 登录mongodb的st2数据库
use st2
db.auth("stackstorm","OLQaFY714tcl9WRoBn4OHJjK")
结果如下:

2 action表结构分析
首先相关的表有:
action_alias_d_b
action_d_b
action_execution_d_b
action_execution_output_d_b
action_execution_scheduling_queue_item_d_b
action_execution_state_d_b
接下来一个一个表分析。
2.1 action_d_b分析
db.action_d_b.findOne()
输出结果样例如下:
> db.action_d_b.findOne()
{
"_id" : ObjectId("5c3823a59dc6d67dc88dbda1"),
"uid" : "action:core:announcement",
"metadata_file" : "actions/announcement.yaml",
"name" : "announcement",
"ref" : "core.announcement",
"description" : "Action that broadcasts the announcement to all stream consumers.",
"enabled" : true,
"entry_point" : "",
"pack" : "core",
"runner_type" : {
"name" : "announcement"
},
"parameters" : {
"message" : {
"type" : "object",
"description" : "Message to broadcast."
},
"experimental" : {
"default" : true,
"immutable" : true
}
},
"output_schema" : {
},
"notify" : {
}
}
分析:
这里介绍了core.announcement这个action的具体信息。
查看:
db.action_d_b.findOne({'ref': 'default.counter'})
输出样例结果如下:
> db.action_d_b.findOne({'ref': 'default.counter'})
{
"_id" : ObjectId("5c6f61f59dc6d64891ab5330"),
"uid" : "action:default:counter",
"metadata_file" : "actions/counterActionMeta.yaml",
"name" : "counter",
"ref" : "default.counter",
"description" : "counter action description",
"enabled" : true,
"entry_point" : "counterAction.py",
"pack" : "default",
"runner_type" : {
"name" : "python-script"
},
"parameters" : {
"count" : {
"position" : 1,
"required" : true,
"type" : "integer",
"description" : "the count parameter"
},
"age" : {
"position" : 2,
"required" : true,
"type" : "integer",
"description" : "the age parameter"
},
"cmd" : {
"position" : 0,
"required" : true,
"type" : "string",
"description" : "the cmd parameter"
},
"params" : {
"position" : 3,
"required" : true,
"type" : "string",
"description" : "the params parameter"
}
},
"output_schema" : {
},
"notify" : {
}
}
分析:
uid: 作用尚不清楚 , 样例: "action:default:counter"
name: action的名称， 样例: counter
ref : 可以被其他actionchain或者mistral或者rule引用的动作名称， 样例: "default.counter"
metadata_file: action的元数据文件 , 样例: "actions/counterActionMeta.yaml"
entry_point: action的脚本文件， 样例: "counterAction.py"
pack: action所在的包名称
runner_type: 运行该action的运行器的类型， 是一个字典，样例: {"name" : "python-script"},
parameters: 该action脚本文件需要的参数，是字典，字典中每个元素(也就是该action脚本的一个参数信息)是一个字典，样例如下:
{
"count" : {
"position" : 1,
"required" : true,
"type" : "integer",
"description" : "the count parameter"
},
"age" : {
"position" : 2,
"required" : true,
"type" : "integer",
"description" : "the age parameter"
},
"cmd" : {
"position" : 0,
"required" : true,
"type" : "string",
"description" : "the cmd parameter"
},
"params" : {
"position" : 3,
"required" : true,
"type" : "string",
"description" : "the params parameter"
}
}
而counterActionMeta.yaml
内容如下:
name: "counter"
description: "counter action description"
runner_type: "python-script"
enabled: true
entry_point: "counterAction.py"
parameters:
cmd:
type: "string"
description: "the cmd parameter"
required: true
position: 0
count:
type: "integer"
description: "the count parameter"
required: true
position: 1
age:
type: "integer"
description: "the age parameter"
required: true
position: 2
params:
type: "string"
description: "the params parameter"
required: true
position: 3
比较action的元数据文件和mongodb中action_d_b这个表中定义的动作
两者很很相似。
可以推断: action的元数据文件用于action_d_b这个表中定义对应的动作
查看:
db.action_d_b.findOne({'ref': 'default.multiTask'})
输出结果样例如下:
> db.action_d_b.findOne({'ref': 'default.multiTask'})
{
"_id" : ObjectId("5c8f2acd9dc6d64fd709a7ae"),
"uid" : "action:default:multiTask",
"metadata_file" : "actions/multiTaskMistralMeta.yaml",
"name" : "multiTask",
"ref" : "default.multiTask",
"description" : "multi task mistral description",
"enabled" : true,
"entry_point" : "workflows/multiTaskMistral.yaml",
"pack" : "default",
"runner_type" : {
"name" : "mistral-v2"
},
"parameters" : {
"count" : {
"required" : true,
"type" : "integer"
},
"age" : {
"default" : 20,
"type" : "integer"
},
"cmd" : {
"required" : true,
"type" : "string"
},
"params" : {
"type" : "string"
},
"timeout" : {
"default" : 60,
"type" : "integer"
}
},
"output_schema" : {
},
"notify" : {
}
}
分析: 同上
总结:
action_d_b实际就是st2的动作表，里面包含了每个动作的详细信息，例如:
动作名称，元数据文件，脚本文件，参数，是否开启，锁在的pakc等。
2.2 action_alias_d_b分析
db.action_alias_d_b.findOne()
1) 查询任意一条数据

分析:
目前发现action_alias_d_b这个表中的记录的ref大多是:
packs.pack_get
packs.pack_install
st2_actions_list
st2_executions_list
st2.st2_rules_list
st2_sensors_list
这些实际就是st2中自带的一些动作，推断 action_alias_d_b 中的动作都是st2自带的动作，
但不确定。
总结:
action_alias_d_b尚不清楚，推断是st2_actions_list
st2_executions_list
st2.st2_rules_list
等st2内置的动作表。
3 action_execution_d_b分析
3.1 任意一条数据分析
db.action_execution_d_b.findOne()

分析:
1) action_execution_d_b表的作用应该是记录一个动作具体的一次执行情况。
2) action_execution_d_b表的一条记录大致可以分为4块内容:
第一部分是action， 第二部分是runner， 第三部分是liveaction,第四部分是result
action部分:
是介绍此次action执行的action的具体信息，主要包括:
action的元数据文件，脚本文件，运行器类型，参数等。

总结:
action_execution_d_b表主要是记录一个动作具体的一次执行情况。
一次动作的执行情况大致可以分为4块内容:
第一部分是action(介绍待执行的action参数，元数据文件，脚本文件等)，
第二部分是runner(介绍执行该action的运行器，模块，所在包等)，
第三部分是liveaction(介绍action名称，传入的action执行的参数，运行情况等),
第四部分是result(介绍是否成功/失败，输出结果等)

综上总结:
动作相关的表如下:
action_d_b: 实际就是st2的动作表，里面包含了每个动作的详细信息，例如: 动作名称，元数据文件，脚本文件，参数，是否开启，所在的pakc等。
action_alias_d_b: 尚不清楚，推断是st2_actions_list，st2_executions_list，st2.st2_rules_list等st2内置的动作表。
action_execution_d_b: 主要是记录一个动作具体的一次执行情况。一次动作的执行情况大致可以分为4块内容:
第一部分是action(介绍待执行的action参数，元数据文件，脚本文件等)，
第二部分是runner(介绍执行该action的运行器，模块，所在包等)，
第三部分是liveaction(介绍action名称，传入的action执行的参数，运行情况等),
第四部分是result(介绍是否成功/失败，输出结果等)
action_execution_output_d_b:不清楚
live_action_d_b :不清楚(这个表应该挺重要)
action_execution_state_d_b :数据为空，无法分析，不清楚
action_execution_scheduling_queue_item_d_b: 数据为空，无法分析，不清楚
runner_type_d_b: 定义了不同的运行器类型，例如python-script,local-shell-script等,包含每个运行器的名称，模块，参数，输出样式等
规则相关的表如下:
rule_d_b: 主要就是定义各个规则，每个规则包含名称，引用名称，trigger, criteria, action等信息。
rule_type_d_b: 没有看出来 rule_type_d_b的作用
rule_enforcement_d_b: 不清楚，看上去应该是校验某个规则是否可以执行
pack相关的表如下:
pack_d_b: 就是定义了每个pack的信息，每个pack包含名称，引用名称，文件列表，包路径等信息。
传感器和触发器相关的表如下:
sensor_type_d_b: 主要就是定义不同的传感器类型，每个传感器包括: 传感器执行的python文件的类名，触发器类型，元数据文件等。
trigger_type_d_b: 定义了各个触发器，每个触发器包含元数据文件，发送给规则的数据的字段信息等。
trigger_d_b: 表看上去也是罗列来了每个触发器，不清楚这个表的作用是什么
trigger_instance_d_b: 应该是记录每个触发器每次触发的实例，每个触发器触发实例中包含了本次触发传递给rule中的payload数据。
执行相关的表如下:
trace_d_b: 不清楚，这张表应该挺重要
task_execution_d_b: 数据为空，无法分析，不清楚
