Hi,
Which daemon monitor and doing logrotate?

Its not a daemon but an application (see 'man logrotate') but log rotation usually is driven by a cron job.

It seems there should be a cronjob to execute logrotate command with relevant logrotate configuration, if logs are fast growing then we should decide how often need to rotate the logs by cronjob.

What is your question?

Aah may be not clean enough..!! if no daemon monitor the logrotate process, either need to manually rotatate the logs(#logrotate --force /etc/logrotate.d/someconfig.conf) or need to add in the cronjob to execute the (#logrotate /etc/logrotate.d/someconfig.conf)

I am worrying about the effectiveness of adding logrotate in cronjob for fast growing logs

Logrotate allows you to rotate on several criteria like log file size and it allows you to execute a specific configuration file only. So if a log file is expected to grow to say 100mb within an hour it's easy to add a specific logrotate cron job addressing only that log file.
