联系方式
联系方式
联系方式主要用途有两个
- 可以控制用户信息中展示哪些联系方式,把不会用到的联系方式可以关闭
- 有时候用户自己新增加的通知媒介,比如公司内部的im,需要配置用户的联系方式,可以在这里创建
新增联系方式后可以在创建用户-联系方式选择。
使用场景
用户自己创建的通知媒介和联系方式主要在自定义通知脚本中使用,下面是一个脚本调用举例,你可以参考样例脚本,对接自己的内部通信工具。
系统会把告警事件的内容encode成json,然后通过stdin的方式传给通知脚本,脚本示例如下:
#!/usr/bin/env python
# -*- coding: UTF-8 -*-
import sys
import json
import urllib2
reload(sys)
sys.setdefaultencoding('utf8') # 设置默认编码为utf-8
class Sender(object):
@classmethod
# 方法send_newtalk,newtalk要和配置的通知媒介一致;
def send_newtalk(cls, payload):
try:
#print("Starting send_newtalk".encode('utf-8'))
# 从payload中获取事件数据
event = payload.get('event')
# 获取通知用户对象
users = event.get("notify_users_obj")
# 获取告警规则名称
rule_name = event.get("rule_name")
# 默认事件状态为“触发
event_state = "Triggered"
# 如果事件已恢复,则状态为“恢复”
if event.get("is_recovered"):
event_state = "Recovered"
# 用于存储Dingtalk机器人令牌和用户电话
tokens = {}
phones = {}
#print("Extracting user information".encode('utf-8'))
# 遍历用户,收集电话和Dingtalk令牌
for u in users:
if u.get("phone"):
phones[u.get("phone")] = 1
contacts = u.get("contacts")
# dingtalk_robot_token,需要根据需求替换对应名称,在夜莺通知设置-联系方式设定名称,用户里面配置参数
if contacts.get("dingtalk_robot_token", ""):
tokens[contacts.get("dingtalk_robot_token", "")] = 1
# 设置请求头
headers = {
"Content-Type": "application/json;charset=utf-8"
}
#print("Tokens: {}".format(tokens).encode('utf-8'))
#print("Phones: {}".format(phones).encode('utf-8'))
# 遍历令牌,构建请求并发送到Dingtalk
for t in tokens:
url = "https://oapi.dingtalk.com/robot/send?access_token={}".format(t)
body = {
"msgtype": "markdown",
"markdown": {
"title": "{} - {}".format(event_state, rule_name),
"text": "{} {}".format(payload.get('tpls').get("dingtalk.tpl", "dingtalk.tpl not found"), ' '.join(["@"+i for i in phones.keys()]))
},
"at": {
"atMobiles": list(phones.keys()),
"isAtAll": False
}
}
#print("Sending request to URL: {}".format(url).encode('utf-8'))
#print("Request body: {}".format(body).encode('utf-8'))
data = json.dumps(body)
req = urllib2.Request(url, data=data, headers=headers)
req.get_method = lambda: "POST"
response = urllib2.urlopen(req)
result = response.read()
#print("Response status code: {}".format(response.getcode()).encode('utf-8'))
#print("Response text: {}".format(result).encode('utf-8'))
# 捕获所有异常,防止程序崩溃
except Exception as e:
#print("Error in send_newtalk: {}".format(e).encode('utf-8'))
def main():
try:
#print("Reading payload from stdin".encode('utf-8'))
payload = json.load(sys.stdin)
with open(".payload", 'w') as f:
f.write(json.dumps(payload, indent=4))
#print("Payload written to .payload file".encode('utf-8'))
for ch in payload.get('event').get('notify_channels'):
send_func_name = "send_{}".format(ch.strip())
#print("Processing channel: {}, function name: {}".format(ch, send_func_name).encode('utf-8'))
if not hasattr(Sender, send_func_name):
#print("Function {} not found".format(send_func_name).encode('utf-8'))
continue
send_func = getattr(Sender, send_func_name)
send_func(payload)
except Exception as e:
print("Error in main: {}".format(e).encode('utf-8'))
def hello():
print("hello nightingale".encode('utf-8'))
if __name__ == "__main__":
if len(sys.argv) == 1:
main()
elif sys.argv[1] == "hello":
hello()
else:
print("I am confused".encode('utf-8'))
示例脚本中有很多 print 打印的输出,主要是为了方便调试使用。如果开启,可通过 n9e 的日志进行查看,日志调试在 INFO.log,报错状态在 ERROR.log,过滤关键词 event_script_notify
