This can be fixed by enabling sflow service in init_cfg.json.j2. But need to know what is the reason for disabling sflow? was it causing delayed startup or any ? Why the monit script is checking for a disabled service?

The Monit to monitor the processes in sflow container is merged into repo before sflow service is disabled. Right now I am working on the solution which will not monitor the processes in the service according to whether such service is enabled or disabled in configuration file.
