=pod
=head1 NAME
pt-stalk - Wait for a condition to occur then begin collecting data.
=head1 OPTIONS
=over
=item --collect
default: yes; negatable: yes
Collect system information.
=item --collect-gdb
Collect GDB stacktraces.
=item --collect-oprofile
Collect oprofile data.
=item --collect-strace
Collect strace data.
=item --collect-tcpdump
Collect tcpdump data.
=item --cycles
type: int; default: 5
Number of times condition must be met before triggering collection.
=item --daemonize
default: yes; negatable: yes
Daemonize the tool.
=item --dest
type: string
Where to store collected data.
=item --disk-byte-limit
type: int; default: 100
Exit if the disk has less than this many MB free.
=item --disk-pct-limit
type: int; default: 5
Exit if the disk is less than this %full.
=item --execute-command
type: string; default: pt-collect
Location of the C<pt-collect> tool.
=item --function
type: string; default: status
Built-in function name or plugin file name which returns the value of C<VARIABLE>.
Possible values are:
=over
=item * status
Grep the value of C<VARIABLE> from C<mysqladmin extended-status>.
=item * processlist
Count the number of processes in C<mysqladmin processlist> whose
C<VARIABLE> column matches C<MATCH>. For example:
TRIGGER_FUNCTION="processlist" \
VARIABLE="State" \
MATCH="statistics" \
THRESHOLD="10"
The above triggers when more than 10 processes are in the "statistics" state.
C<MATCH> must be specified for this trigger function.
=item * magic
TODO
=item * plugin file name
A plugin file allows you to specify a custom trigger function. The plugin
file must contain a function called C<trg_plugin>. For example:
trg_plugin() {
# Do some stuff.
echo "$value"
}
The last output if the function (its "return value") must be a number.
This number is compared to C<THRESHOLD>. All L<"ENVIRONMENT"> variables
are available to the function.
Do not alter the tool's existing global variables. Prefix any plugin-specific
global variables with "PLUGIN_".
=back
=item --help
Print help and exit.
=item --interval
type: int; default: 1
Interval between checks.
=item --iterations
type: int
Exit after triggering C<pt-collect> this many times. By default, the tool
will collect as many times as it's triggered.
=item --log
type: string; default: /var/log/pt-stalk.log
Print all output to this file when daemonized.
=item --match
type: string
Match pattern for C<processles> L<"--function">.
=item --notify-by-email
type: string
Send mail to this list of addresses when C<pt-collect> triggers.
=item --pid FILE
type: string; default: /var/run/pt-stalk.pid
Create a PID file when daemonized.
=item --retention-time
type: int; default: 30
Remove samples after this many days.
=item --run-time
type: int; default: 30
How long to collect statistics data for?
Make sure that this isn't longer than SLEEP.
=item --sleep
type: int; default: 300
How long to sleep after collecting?
=item --threshold N
type: int; default: 25
Max number of C<N> to tolerate.
=item --variable NAME
type: string; default: Threads_running
This is the thing to check for.
=item --version
Print tool's version and exit.
=back
=head1 ENVIRONMENT
No env vars used.
=cut
