PT-SIFT(1) User Contributed Perl Documentation PT-SIFT(1)NAMEpt-sift - Browses files created by pt-stalk.
SYNOPSIS
Usage: pt-sift FILE|PREFIX|DIRECTORY
pt-sift browses files created by pt-stalk. If no options are given,
the tool browses all pt-stalk files in "/var/lib/pt-stalk" if that
directory exists, else the current working directory is used. If a
FILE is given, the tool browses files with the same prefix in the given
file's directory. If a PREFIX is given, the tool browses files in
"/var/lib/pt-stalk" (or the current working directory) with the same
prefix. If a DIRECTORY is given, the tool browses all pt-stalk files
in it.
RISKS
Percona Toolkit is mature, proven in the real world, and well tested,
but all database tools can pose a risk to the system and the database
server. Before using this tool, please:
· Read the tool's documentation
· Review the tool's known "BUGS"
· Test the tool on a non-production server
· Backup your production server and verify the backups
DESCRIPTIONpt-sift downloads other tools that it might need, such as pt-diskstats,
and then makes a list of the unique timestamp prefixes of all the files
in the directory, as written by the pt-stalk tool. If the user
specified a timestamp on the command line, then it begins with that
sample of data; otherwise it begins by showing a list of the timestamps
and prompting for a selection. Thereafter, it displays a summary of
the selected sample, and the user can navigate and inspect with
keystrokes. The keystroke commands you can use are as follows:
· d
Sets the action to start the pt-diskstats tool on the sample's disk
performance statistics.
· i
Sets the action to view the first INNODB STATUS sample in less.
· m
Displays the first 4 samples of SHOW STATUS counters side by side
with the pt-mext tool.
· n
Summarizes the first sample of netstat data in two ways: by
originating host, and by connection state.
· j
Select the next timestamp as the active sample.
· k
Select the previous timestamp as the active sample.
· q
Quit the program.
· 1
Sets the action for each sample to the default, which is to view a
summary of the sample.
· Sets the action to just list the files in the sample.
· *
Sets the action to view all of the sample's files in the less
program.
OPTIONS--help

--version
