python - Sensu:客户端套接字输入(如何打印事件)

Question

我正在尝试使用此处描述的“客户端套接字输入”创建一个事件:https://sensuapp.org/docs/latest/reference/clients.html#client-socket-input

当我这样做时，来自 bash:

echo '{"status": 1, "output": "x.x.x.x/22 [AS0000] | NotFound. No VRP Covers the Route Prefix.", "name": "err_rpki_rr.py"}' > /dev/tcp/localhost/3030

有效(我可以在 Uchiwa 中看到该事件)，但是当我这样做时，来自 python 代码:

print json.dumps(msg)

$ python err_rpki_rr.py > /dev/tcp/localhost/3030

{"status": 1, "output": "x.x.x.x/22 [AS0000] | NotFound. No VRP Covers the Route Prefix.", "name": "err_rpki_rr.py"}
{"status": 1, "output": "y.y.y.y/22 [AS0000] | NotFound. No VRP Covers the Route Prefix.", "name": "err_rpki_rr.py"}

Sensu 提示:

==> sensu-client.log <==
{"timestamp":"2016-07-11T22:02:21.698967+0200","level":"warn","message":"discarding data buffer for sender and closing connection","data":"{\"status\": 1, \"output\": \"x.x.x.x/22 [AS0000] | NotFound. No VRP Covers the Route Prefix.\", \"name\": \"err_rpki_rr.py\"}\n{\"status\": 1, \"output\": \"y.y.y.y/22 [AS0000] | NotFound. No VRP Covers the Route Prefix.\", \"name\": \"err_rpki_rr.py\"}\n","parse_error":"unexpected characters after the JSON document at line 2, column 1 [parse.c:590]"}

看来不是儿子本身引起了这个问题，而是换行符引起的。如何将每条打印消息重定向到 >/dev/tcp/localhost/3030 ？

Answer 1

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect( ("localhost",3030) )
sock.sendall(json.dumps(msg))
sock.close()

成功了:)
