PROGRAM:
NAME
vv_treemap - Interactive and dynamic treemap visualization of a Paje trace file
SYNOPSIS
vv_treemap [OPTIONS] <TRACEFILE>
DESCRIPTION
The vv_treemap(1) command displays a dynamic, interactive and hierarchical treemap
visualization of a Paje trace file. It is dynamic since the user can change in runtime the
time slices that should be applied to calculate the treemap. This interactivity is
enhanced by enabling the selection of specific types and containers to be rendered. Most
of the times, the user should do it in first place, since most of the metrics registered
in traces are incompatible among them. Since the Paje trace file is naturally hierarchical
(see the trace format description for details), vv_treemap reflects that in the
representation: the user can change the level of details by using the mouse scroll within
the main window. The vv_treemap tool is a particularly useful program to compare the
behavior of processes/threads (containers) on different time scales. If wisely used, it
can be show the imbalances that might occur in a parallel application, for instance. A
good analysis using vv_treemap depends on the dynamic selection of performance metrics
along with a good time slice configuration.
OPTIONS
vv_treemap accepts the following options:
-a, --stop-at=TIME
Stop the trace simulation at TIME. This way the user won’t have to wait until the
complete trace is loaded (and simulated) into memory.
-f, --flex
Use a flex-based file reader. The flex reader of PajeNG framework can be used in
vv_treemap to allow an alternative way of reading trace files. In some rare
situations, it might be faster to read trace files with this option.
-n, --no-strict
Support old file names in event definitions.
-z, --ignore-incomplete-links
Tells the PajeNG simulator to ignore incomplete links. Only use if you know what you
are doing, since most of the times, incomplete links indicate a corrupted or malformed
trace file.
-?, --help
Show all the available options.
--usage
Give a short usage message.
