show profiling

Dump profiling details.

Description

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

To sort by address instead of usage, specify the byaddr argument.

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-2.4/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-2.4/hapee-lb.sock
