Gnuplot error #1607

Open marija1705 opened 5 years ago

marija1705 commented 5 years ago

GUI on one of the nodes is not working anymore and is producing the following error:

Request failed: Internal Server Error java.io.IOException: Cannot run program "/tmp/.tsdb/tsdb-gnuplot/mygnuplot.sh": error=2

Looking on the server, the /tmp/opentsdb has indeed disappeared. Recreating it manually is fixing the issue (temporarily).

I've run into this issue too. In my case there were cron jobs on the same node that periodically cleared the contents of /tmp.

Probably best to set java.io.tmpdir, see https://github.com/OpenTSDB/opentsdb/blob/14ab3ef8a865816cf920aa69f2e019b7261a7847/src/tools/GnuplotInstaller.java#L42.

If you're running OpenTSDB on RedHat/CentOS, you can also change the behaviour of the cleanup by editing /etc/cron.daily/tmpwatch (RHEL/CentOS 6) or /usr/lib/tmpfiles.d/tmp.conf (RHEL/CentOS 7+) and prevent it from deleting the directory
