Have a checking on that directory to make sure you have 'write' permission on it:) ________________________________ From: Li, Cathy Sent: 2009年7月24日 11:50 To: Zhang, Austin; Johnson, Ryan A; dev@moblin.org Subject: RE: [Moblin Dev] bootchart (was "how to calculate boottime in moblin?") I tried “#bootchart -o test.png /var/log”, but get errors ”IOError: error while writing to output stream”, while “#bootchart /var/log” works fine.

Now, don't need trouble like that. In the recently moblin image, you can achieve that by: bootchart -o test.png /var/log --> to get the png file in Moblin directly Or you can: bootchart /var/log --> to see the picture launched in Moblin directly -----Original Message----- From: dev-boun...@moblin.org [mailto:dev-boun...@moblin.org] On Behalf Of Li, Cathy Sent: 2009年7月24日 10:25 To: Johnson, Ryan A; dev@moblin.org Subject: Re: [Moblin Dev] bootchart (was "how to calculate boottime in moblin?") I’m not sure why the PNG file wasn’t generated in /var/log/ in your netbook. But one workaround is to copy bootchart.tgz to your working PC (Linux system such as installed FC10), yum install bootchart on your working PC, then use command “#bootchart bootchart.tgz” to generate the PNG file.

I've installed bootchart from the moblin repo, and after booting up, it creates /var/log/bootchart.tgz. However I am not seeing the PNG file as mentioned above. It appears that the moblin build of bootchart doesn't depend on java for creating the graphical output, and instead installs /usr/bin/bootgraph.py, which I see can create SVG files from dmesg output. However I am not seeing how to use it for the bootchart.tgz output. What am I missing?
