show profiling

Description

Specify the category of data desired: status, tasks, memory, or all.

By default, output is sorted by usage. As an alternative, you can specify the byaddr or bytime argument to sort by address or by total execution time, respectively.

Specify the aggr argument to aggregate task activity by called function instead of displaying all details.

By default, all profiling information is dumped. To limit the number of lines of output for each category, append a maximum line limit.

Examples

Show profiling settings, one per line, as well as the command needed to change them.

$ echo "show profiling status" | \
   sudo socat stdio unix-connect:/var/run/hapee-2.7/hapee-lb.sock

Per-task CPU profiling              : on            # set profiling tasks {on|auto|off}
Memory usage profiling              : off           # set profiling memory {on|off}

Report details for the top three tasks, sorted by time:

$ echo "show profiling tasks bytime 3" | \
   sudo socat stdio unix-connect:/var/run/hapee-2.7/hapee-lb.sock
