pt-query-digest --processlist can't merge correctly show full processlist outputs for slave thread. As a result wrong queries could be listed in a report.
percona toolkit 2.1.8 and 2.1.5 versions are affected.
/usr/local/sbin/pt-query-digest --interval 0.2 --filter '$event->{Query_time} > 1' --processlist h=SERVER,u=USER -p PASSWORD --print --no-report --run-time 3600 > logs/SERVER-`date +%Y%m%d-%H`
