Bustle is a better
dbus-monitor! It records and draws sequence diagrams of
D-Bus activity, showing signal emissions,
method calls and their corresponding returns, with timestamps for each
individual event and the duration of each method call. This can help you check
for unwanted D-Bus traffic, and pinpoint why your D-Bus-based application isn't
performing as well as you like. It also provides statistics like signal
frequencies and average method call times.
Bustle 0.4.8 (2015-03-22)
- Be compatible with recent versions of Gtk2HS which use Text rather than Strings in many places. Should still build against older releases. Let me know if not.
- #89712: Add symbolic icon. (Arnaud Bonatti)
- Binary tarballs: x86_64 (signature); i486 (signature). You will need a recent-ish Glib and GTK+ 2 installed.
- Source: Hackage; tarball (signature); git.
- Older releases are available if you like laborious archæology.
- Open bugs; file a new bug.
- If you'd like to get involved, but don't know where to start, take a look at bugs flagged with the 'love' keyword, which we hope are good introductory tasks. Chat to wjt on freenode if you'd like a helping hand!
Now click File → New… to start recording session bus traffic. When you're done, click Stop, and explore the log.
If you want to record traffic without running the UI (maybe on an embedded platform which doesn't have Gtk+ and/or a Haskell compiler), you can use the stand-alone logger:
You can then open
logfile.bustle in Bustle.
You can also get some ASCII-art version of the statistics shown in the UI:
bustle --count logfile.bustle bustle --time logfile.bustle
If you want to log all system bus traffic, you need to edit
/etc/dbus/system.conf to enable eavesdropping, and then remove the include of
/etc/dbus-1/system.conf.d which seems to re-enable strictness. Then you can run
the stand-alone logger against the system bus:
bustle-pcap --system system-log.bustle
Please remember to undo these changes when you're done.
