[ldv-project] Cannot visit port 8999 after installing statistics visualization

[Qiuping Yi]

I will check the versions of LDV Tools and LDV Analytics Center after my trip. I just remember I download the whole tool at the end of 2013. So maybe it is not the latest one. 

In addition，you say you have limited the consumption on time of blast to 15minutes. However, when I run blast alone on a main function with the command recorded in file xxx.ko.1.gz generated by ldv, blast took about one hour, but ldv still completed the task under the limitation of 15 minutes. I feel strange about the two very different results, could you explain them to me? Thank you very much.

Best regards,
Lucefe

I guess "Time" is the sum of the columns under "Children time" which contains "CPP", "PBLAST.OPT" and "SMT_SOLVER", but I found this is always not true. In addition, I found that NOT all the three time ( "CPP", "PBLAST.OPT" and "SMT_SOLVER") are listed for all tasks. For example, from some task, "PBLAST.OPT" may be omitted, and for some other task, "SMT_SOLVER" may be omitted. SO what is the rule?

It looks that you need to update them up to 0.5 and 0.09 correspondingly, since in LDV Tools v0.5 we have considerably changed resource consumption measurement mechanism (http://linuxtesting.org/20-02-2014). For instance, I see statics like in the picture attached. Please read carefully changes to INSTALL file in v0.5!

For example, I checked driver(drivers/gpu/drm/vmwgfx), the stats visualization tool shew that the Time is "375, 00" In addition, it also shew three sub column under "Children time", where "CPP" is "0, 04" "PBLAST.OPT"  is "329, 31" and "SMT_SOLVER" is "338, 17".

However, after the command is carried out successfully without any error message and web server was restarted with command /etc/init.d/apache2 stop&start, I can not visit http://localhost:8999 by means of my browser.
