Описание (Description)
dbpmda is an interactive interface to the interactions between a
Performance Metric Domain Agent (PMDA(3)) and the Performance
Metric Collector Daemon (pmcd(1)). This allows PMDAs to be
attached, initialized and exercised to test for correctness.
dbpmda interactively prompts the user for commands, many of which
emulate the Protocol Data Units (PDUs) that may be sent by a
pmcd(1) process. After running dbpmda, enter the command help to
get a list of the available commands. The example section below
illustrates a session using dbpmda to test a PMDA.
To simplify repetitive testing of a PMDA, the file .dbpmdarc in
the current working directory can contain a list of commands that
will be executed by dbpmda on startup, before the user is
prompted to enter further commands interactively. While
processing the .dbpmdarc file, interactive mode and command
echoing are enabled and then reset at the end of the .dbpmdarc
file (see the -i and -e command line options below).
The -f command line option prevents startup processing of a
.dbpmdarc file (if it exists).
If the system supports readline(3) then this will be used to read
commands when input is from a tty device, so history and command
line editing are available.
As there are no timeout constraints on a PMDA while using dbpmda
(as compared to pmcd(1)), another debugger like gdb(1) can be
used on the PMDA process once it has been attached to dbpmda.
