zabbix_sender的实际例子
#!/usr/bin/env python # -*- coding: utf-8 -*- import socket import struct import simplejson class ZabbixSender: zbx_header = 'ZBXD' zbx_version = 1 zbx_sender_data = {u'request': u'sender data', u'data': []} send_data = '' def __init__(self, server_host, server_port = 10051): self.server_ip = socket.gethostbyname(server_host) self.server_port = server_port def AddData(self, host, key, value, clock = None): add_data = {u'host': host, u'key': key, u'value': value} if clock != None: add_data[u'clock'] = clock self.zbx_sender_data['data'].append(add_data) return self.zbx_sender_data def ClearData(self): self.zbx_sender_data['data'] = [] return self.zbx_sender_data def __MakeSendData(self): zbx_sender_json = simplejson.dumps(self.zbx_sender_data, separators=(',', ':'), ensure_ascii=False).encode('utf-8') json_byte = len(zbx_sender_json) self.send_data = struct.pack("<4sBq" + str(json_byte) + "s", self.zbx_header, self.zbx_version, json_byte, zbx_sender_json) def Send(self): self.__MakeSendData() so = socket.socket() so.connect((self.server_ip, self.server_port)) wobj = so.makefile(u'wb') wobj.write(self.send_data) wobj.close() robj = so.makefile(u'rb') recv_data = robj.read() robj.close() so.close() tmp_data = struct.unpack("<4sBq" + str(len(recv_data) - struct.calcsize("<4sBq")) + "s", recv_data) recv_json = simplejson.loads(tmp_data[3]) return recv_data if __name__ == '__main__': sender = ZabbixSender(u'127.0.0.1') for num in range(0,2): sender.AddData(u'Zabbix server', u'test', u'sent data' + str(num)) res = sender.Send() print sender.send_data print res
上面的代码中
sender.AddData(u'Zabbix server', u'test', u'sent data' + str(num))
Zabbix Server为host
test为key
sent data 为value
当然,大家应该很想知道以上代码运行的结果吧,看下面
这样就用python写了一个zabbix_sender的程序,以上的代码,只要稍作改变,即可用于我们的运维系统,如果有实际的需要。
主要步骤是和Zabbix server建立socket连接,发送zabbix的数据,注意头部信息的正确性,最后就是发送实际的数据,Zabbix server对数据进行处理响应。
官方文档为https://www.zabbix.org/wiki/Docs/protocols
下面是官方文档中java的例子
String report = buildJSonString(...);
writeMessage(stream, report.getBytes());
...
private String buildJSonString(String host, String item, String value)
{
return "{"
+ "\"request\":\"sender data\",\n"
+ "\"data\":[\n"
+ "{\n"
+ "\"host\":\"" + host + "\",\n"
+ "\"key\":\"" + item + "\",\n"
+ "\"value\":\"" + value.replace("\\", "\\\\") + "\"}]}\n" ;
}
protected void writeMessage(OutputStream out, byte[] data) throws IOException {
int length = data.length;
out.write(new byte[] {
'Z', 'B', 'X', 'D',
'\1',
(byte)(length & 0xFF),
(byte)((length >> 8) & 0x00FF),
(byte)((length >> 16) & 0x0000FF),
(byte)((length >> 24) & 0x000000FF),
'\0','\0','\0','\0'});
out.write(data);
}
能自己写zabbix sender有什么好处,当然就是可以用自己的程序来发送数据给zabbix server,将极大的扩展了zabbix应用的范围和可编程性。
