The two main categories of risks are those created by the nature of the tool (e.g. read-only tools vs. read-write tools) and those created by bugs. .PP pt-mext is a read-only tool. It should be very low-risk. .PP At the time of this release, we know of no bugs that could cause serious harm to users. .PP The authoritative source for updated information is always the online issue tracking system. Issues that affect this tool will be marked as such. You can see a list of such issues at the following \s-1URL:\s0 http://www.percona.com/bugs/pt\-mext . .PP See also \*(L"\s-1BUGS\s0\*(R" for more information on filing bugs and getting help. .SH "DESCRIPTION" .IX Header "DESCRIPTION" pt-mext executes the \f(CW\*(C`COMMAND\*(C'\fR you specify, and reads through the result one line at a time. It places each line into a temporary file. When it finds a blank line, it assumes that a new sample of \s-1SHOW\s0 \s-1GLOBAL\s0 \s-1STATUS\s0 is starting, and it creates a new temporary file. At the end of this process, it has a number of temporary files. It joins the temporary files together side-by-side and prints the result. If the \*(L"\-r\*(R" option is given, it first subtracts each sample from the one after it before printing results. .SH "OPTIONS" .IX Header "OPTIONS" .IP "\-r" 4 .IX Item "-r" Relative: subtract each column from the previous column. .SH "ENVIRONMENT" .IX Header "ENVIRONMENT" This tool does not use any environment variables. .SH "SYSTEM REQUIREMENTS" .IX Header "SYSTEM REQUIREMENTS" This tool requires the Bourne shell (\fI/bin/sh\fR) and the seq program. .SH "BUGS" .IX Header "BUGS" For a list of known bugs, see http://www.percona.com/bugs/pt\-mext . .PP Please report bugs at https://bugs.launchpad.net/percona\-toolkit .

Percona Toolkit was forked from two projects in June, 2011: Maatkit and Aspersa. Those projects were created by Baron Schwartz and developed primarily by him and Daniel Nichter, both of whom are employed by Percona.
