Sensu：客戶端套接字輸入（如何打印事件）

Question

我正在嘗試使用此處所述的“客戶端套接字輸入”創建事件： https : //sensuapp.org/docs/latest/reference/clients.html#client-socket-input

當我這樣做時，從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

可以工作（我可以在Uchiwa中看到事件），但是當我這樣做時，來自python代碼：

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抱怨：

==> 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]"}

似乎不是引起問題的兒子本身，而是換行符。 如何將每條打印的消息重定向到> /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()

絕招:)
