To perform manual log rotation, use the following procedure to implement a custom log rotation process.
No log messages are lost during the procedure.
1. Rename or archive the vertica.log file that is produced. For example:
$ mv vertica.log vertica.log.1
2. Send the Vertica process the USR1 signal. For example:
$ killall -USR1 vertica
This will create a new vertica.log file. From there configure log rotation so the vertica.log rotates every day
