Subject: run-report: Fix CPU usage stats computation
X-Git-Tag: v2.1.0~20
X-Git-Url: https://git.lttng.org/?p=lttng-tools.git;a=commitdiff_plain;h=1db84787a06a9dcea6ebad95ebefc4e449507ea6;ds=sidebyside

run-report: Fix CPU usage stats computation

The CPU usage statistics are computed by grepping the top command
output. The top output format as since changed so the CPU usage
statistics were not properly computed.

Fix this by adjusting to the new top command output format.
