ovs-parse-leaks(8)

ovs-parse-leaks8

Parses ovs leak checker log files

Usage

ovs-parse-leaks [binary] < log

Overview

Many Open vSwitch daemons accept a --check-leaks option that writes information about memory allocation and deallocation to a log file. ovs-parse-leaks parses log files produced by this option and prints a summary of the results. The most interesting part of the output is a list of memory blocks that were allocated but not freed, which Open vSwitch developers can use to find and fix memory leaks.

The log file must be supplied on standard input. The binary that produced the output should be supplied as the sole non-option argument. For best results, the binary should have debug symbols.

Options

--help

Prints a usage message and exits.

Bugs

The output can be hard to interpret, especially for a daemon that does not exit in normal operation. Using ovs-appctl(8) to invoke the exit command that some Open vSwitch daemons support sometimes helps with this.

ovs-parse-leaks usually incorrectly reports one or more ``bad frees of not-allocated address'' errors at the beginning of output. These reflect frees of data that were allocated before the leak checker was turned on during program initialization.
