You can do this with two nodetool commands: nodetool compactionstats will check on active Merkle Tree calculations.
nodetool netstats will list out any active repair streams. Aaron Morton posted a Bash script/command a while back that you can just paste into the (linux) command line to monitor active streams for you: while true; do date; diff <(nodetool -h localhost netstats) <(sleep 5 && nodetool -h localhost netstats); done Hope this helps, Aaron Ploetz On Mon, Jun 22, 2015 at 8:40 AM, Jean Tremblay < jean.tremb...@zen-innovations.com> wrote: > Hi, > > What is the best way to see if a repair is finished?
