scripts/kvm/kvm_stat: Fix tracefs access checking

2016-02-09T14:45:26+00:00

On kernels build without CONFIG_TRACING kvm_stat will bail out even when traces are not used. This is not very helpful, especially if the user can't install a new kernel. Instead, we should warn the user and fall back to debugfs statistics. These changes check if trace statistics were selected without kernel support, warn with a small timeout, set the debugfs statistics option to True and the tracefs one to False.

scripts/kvm/kvm_stat: Add optparse description

2016-01-26T14:58:13+00:00

Added a description text that explains what the script does and which requirements have to be met to let it run. The help formatter class is needed as the default optparse formatter makes the text unreadable.

scripts/kvm/kvm_stat: Add interactive filtering

2016-01-26T14:58:13+00:00

Interactively changing the filter is much more useful than the drilldown, because it is more versatile. With this patch, the filter can be changed by pressing 'f' in the text ui and entering a new filter regex.

scripts/kvm/kvm_stat: Fixup filtering

2016-01-26T14:58:13+00:00

When filtering, the group leader event should not be disabled, as all other events under it will also be disabled. Also we should make sure that values from disabled fields will not be displayed. This also filters the fields from the log and batch output for better readability. Also the drilldown update now directly checks for the stats' field filter and (un)sets drilldown accordingly.

scripts/kvm/kvm_stat: Fix rlimit for unprivileged users

2016-01-26T14:58:13+00:00

Setting the hard limit as a unprivileged user either returns an error when it is higher than the current one or irreversibly sets it lower. Therefore we leave the hardlimit untouched as long as we don't need to raise it as this needs CAP_SYS_RESOURCE. This gives admins the possibility to run the script as an unprivileged user to increase security.

scripts/kvm/kvm_stat: Read event values as u64

2016-01-26T14:58:13+00:00

The struct read_format, which denotes the returned values on a read states that the values are u64 and not long long which is used for struct unpacking. Therefore the 'q' long long formatter was exchanged with 'Q' which is the format for u64 data.

scripts/kvm/kvm_stat: Cleanup and pre-init perf_event_attr

2016-01-26T14:58:13+00:00

All initializations of the ctypes struct that don't need additional information were moved to its init method. The unneeded initializations for sample_type and sample_period were removed as they do not affect the counters that are read. This improves readability of the setup_event_attribute by halfing its LOC.

scripts/kvm/kvm_stat: Fix output formatting

2016-01-26T14:58:13+00:00

The key names in log mode were capped to 10 characters which is not enough for distinguishing between keys. Capping was therefore removed. In batch mode the spacing between keys and values was too narrow and therefore had to be extended to 42.
