`-c sequence#` | List all events happening after this sequence number.
`-t countername` | List all events after this counter number.
`-c sequence#``-t countername` | Update the supplied counter with the current sequence number and clear the log. This clears the log regardless of which counter name is specified, so only one user can make use of this option.

- The `p4 logger` command is not for end users. It supports propagation of information to an external defect tracking system.
- In multi-server environments, `p4 logger` commands should be issued to the commit server, not to an edge server. If you are using P4 DTG or other third-party tools that make use of this command, ensure that your installation is properly configured.
