tools/kvm_stat: use variables instead of hard paths in help output

2017-07-26T17:04:52+00:00

Using variables instead of hard paths makes the requirements information more accurate. Signed-off-by: Lin Ma Signed-off-by: Paolo Bonzini

tools/kvm_stat: add new interactive command 'b'

2017-06-27T14:44:50+00:00

Toggle display total number of events by guest (debugfs only). When switching to display of events by guest, field filters remain active. I.e. the number of events per guest reported considers only events matching the filters. Likewise with pid/guest filtering. Note that when switching to display of events by guest, DebugfsProvider remains to collect data for events as it did before, but the read() method summarizes the values by pid.

tools/kvm_stat: add new command line switch '-i'

2017-06-27T14:43:48+00:00

It might be handy to display the full history of event stats to compare the current event distribution against any available historic data. Since we have that available for debugfs, we offer a respective command line option to display what's available. Signed-off-by: Stefan Raspl Signed-off-by: Paolo Bonzini

tools/kvm_stat: fix error on interactive command 'g'

2017-06-27T14:41:55+00:00

Fix an instance where print_all_gnames() is called without the mandatory argument, resulting in a stack trace. To reproduce, simply press 'g' in interactive mode. Signed-off-by: Stefan Raspl Signed-off-by: Paolo Bonzini

tools/kvm_stat: display guest list in pid/guest selection screens

2017-06-08T16:24:49+00:00

Display a (possibly inaccurate) list of all running guests. Note that we leave a bit of extra room above the list for potential error messages. Furthermore, we deliberately do not reject pids or guest names that are not in our list, as we cannot rule out that our fuzzy approach might be in error somehow.

tools/kvm_stat: add new interactive command 'o'

2017-06-08T16:24:48+00:00

Add new interactive command 'o' to toggle sorting by 'CurAvg/s' (default) and 'Total' columns. Signed-off-by: Stefan Raspl Signed-off-by: Paolo Bonzini

tools/kvm_stat: add new interactive command 's'

2017-06-08T16:20:21+00:00

Add new command 's' to modify the update interval. Limited to a maximum of 25.5 sec and a minimum of 0.1 sec, since curses cannot handle longer and shorter delays respectively. Signed-off-by: Stefan Raspl Signed-off-by: Paolo Bonzini

tools/kvm_stat: add new interactive command 'h'

2017-06-08T16:17:59+00:00

Display interactive commands reference on 'h'. While at it, sort interactive commands alphabetically in various places. Signed-off-by: Stefan Raspl Signed-off-by: Paolo Bonzini

tools/kvm_stat: rename 'Current' column to 'CurAvg/s'

2017-06-08T16:17:37+00:00

'Current' can be misleading as it doesn't tell whether this is the amount of events in the last interval or the current average per second. Note that this necessitates widening the respective column by one more character. Signed-off-by: Stefan Raspl Signed-off-by: Paolo Bonzini
