Try
Code:
/usr/bin/time -v command

With GNU coreutils, this outputs:
Code:
Command exited with non-zero status 1
        Command being timed: "test"
        User time (seconds): 0.00
        System time (seconds): 0.00
        Percent of CPU this job got: 0%
        Elapsed (wall clock) time (h:mm:ss or m:ss): 0:00.01
        Average shared text size (kbytes): 0
        Average unshared data size (kbytes): 0
        Average stack size (kbytes): 0
        Average total size (kbytes): 0
        Maximum resident set size (kbytes): 0
        Average resident set size (kbytes): 0
        Major (requiring I/O) page faults: 1
        Minor (reclaiming a frame) page faults: 120
        Voluntary context switches: 3
        Involuntary context switches: 1
        Swaps: 0
        File system inputs: 0
        File system outputs: 0
        Socket messages sent: 0
        Socket messages received: 0
        Signals delivered: 0
        Page size (bytes): 4096
        Exit status: 1

Careful not to use just "time", because this might be a shell builtin.

If you need tracing whilst the command is doing its thing, you can use the ps command. The options for that are very much OS specific.
