Start filebeat using a java code?

[Nisal_Thiwanka]

I'm using filebeat to read some log files and I need to start filebeat using a java program. And the filebeat commands are executed using the windows powerShell. I used the following code but it didn't work.

try {
ProcessBuilder b1 = new ProcessBuilder("powershell.exe", "/c", "cd "C:\Program Files\Filebeat" && ./filebeat -e -c filebeat.yml -d "publish"\");
b1.redirectErrorStream(true);
Process p1 = b1.start();
BufferedReader r1 = new BufferedReader(new InputStreamReader(p1.getInputStream()));
String line1;
while (true) {
line1 = r1.readLine();
if (line1 == null) { break; }
System.out.println(line1);
}

}catch(Exception e) {

}

Try this

ProcessBuilder pb = new ProcessBuilder("C:\\Program Files\\Filebeat\\filebeat.exe", "-c", "C:\\Program Files\\Filebeat\\filebeat.yml", "-e");
pb.redirectErrorStream(true);
Process p = pb.start();

BufferedReader bri = new BufferedReader(new InputStreamReader(p.getInputStream()));

String line;
while ((line = bri.readLine()) != null) {
   System.out.println(line);
}
p.waitFor();
