Thank you for the contribution. Could you also update monitor.c to remove the tickcount to nanosecond conversion?
Switch tile_heartbeat to report UNIX nanoseconds instead of raw ticks. Update monitor.c and fd_action.h to remove the ns_per_tic logic and transition the monitoring loop to use wallclock time.

Done. Also removed obsolete ns_per_tic and tic/toc logic. The monitor loop now uses fd_log_wallclock() directly |

Fixes Issue #6848

tile_heartbeatto report UNIX nanoseconds usingfd_log_wallclock()instead of raw ticks.I'm still learning the tribal knowledge of the project, but my assessment is that
fd_log_wallclockis performant enough for the housekeeping path. It maps toclock_gettime(CLOCK_REALTIME), which typically utilizes the vDSO path.
