Counts

Count:

$ cd feedback.osafoundation.org/manage/desktop/fetch
$ ls | wc -l
170

Count with uptime (these are the valid ones, haven't checked what all the other junk is):

$ grep "\<Seconds\-since\-last\-error\>" *|wc -l
138

Count with nonzero uptime:

$ grep "\<Seconds\-since\-last\-error\>" *|grep -v \>0\<|wc -l
84

I am using only the nonzero values for the numbers below, which skews them in our favor. Need to figure out why so many zeros.

Times Between Failures

Lowest uptime:

$ grep "\<Seconds\-since\-last\-error\>" *|grep -v \>0\<|sed "s/[a-zA-Z\<\>\-]//g"|sed "s/.*://"|sed "s/\///"|sort -g|tail -1
1

Highest uptime:

$ grep "\<Seconds\-since\-last\-error\>" *|grep -v \>0\<|sed "s/[a-zA-Z\<\>\-]//g"|sed "s/.*://"|sed "s/\///"|sort -g|tail -1
1013742

(about 281 hours)

Median uptime:

$ grep "\<Seconds\-since\-last\-error\>" *|grep -v \>0\<|sed "s/[a-zA-Z\<\>\-]//g"|sed "s/.*://"|sed "s/\///"|sort -g|head -42 | tail -1

Tracebacks

1824 tracebacks recorded.

toptracebacks (all tracebacks with at least two reports):

Note: I counted these from the last line of the traceback, and selected the latest traceback with that line as last. This means there could be tracebacks that result in the same last line but different path to the exception.
