ZeroDivisionError in bootchart when parsing data from a HP Proliant DL360 G5

Note that it looked to me as if it crashed while parsing the 3rd tgz file.

The crash is actually in pybootchartgui although the bug may lie in data files.

Guys, could you please have a look to this bug to see if the data generated is incorrect?

It is blocking our bootchart metrics for servers in Natty

James, could you have a look at this?

Hi,

I took a look at the third tgz file. The problem is the disk naming. On line 136 of parsing.py you can see the code looks for certain disk names.

def _parse_proc_disk_stat_log(file, numCpu):
 """
 Parse file for disk stats, but only look at the whole disks, eg. sda,
 not sda1, sda2 etc. The format of relevant lines should be:
 {major minor name rio rmerge rsect ruse wio wmerge wsect wuse running use aveq}
 """
 DISK_REGEX = 'hd.$|sd.$|vd.$'

But the log file contains blocks like

 104 5 cciss/c0d0p5 52 30 656 170 0 0 0 0 0 160 170

So if you extend the regex to be

 DISK_REGEX = 'hd.$|sd.$|vd.$|cciss/c0d0$'

the charting will run without crashes.

I'm working on this now.

This bug was fixed in the package pybootchartgui - 0+r141-0ubuntu3

---------------
pybootchartgui (0+r141-0ubuntu3) natty; urgency=low

  * Add patch adding-smart-array-block-devices.patch to allow pybootchartgui
    to run on devices with an HP smart array. (LP: #723663)
