  • 772

I installed opensearch and opensearch-dashboard in my ubuntu vm. When I try to find out the resources used by opensearch-dashboard with the command

top -U opensearch

i just get

Tasks: 125 total,   1 running, 124 sleeping,   0 stopped,   0 zombie

and I think that that kind of infomation aggregate opensearch AND the opensearch-dashboard how can I find out only the memory cpu and disk space used by the dashboard?

    First we need the pid of opensearch dashboards, with this in your terminal:

    PID=$(sudo netstat -plnt | grep 5601 | awk '{print $7}' | cut -d'/' -f1)

    then, for process detail:

    ps -p $PID -o pid,user,%cpu,%mem,comm,args

    if you want to monitor in real time:

    top -p $PID

    and for the disk usage:

    du -sh /usr/share/opensearch-dashboards

    Notice that opensearch can launch multiple process, they may appear as node or opensearch-dashboards
