Known Issues

  • Host monitoring using a password rather than a private key file fails with Host Sensor - (No such file or directory). The workaround is:
    • Open a terminal window on the DBmarlin server logged in as the dbmarlin user and in the dbmarlin install directory.
    • cd scripts/dbadmin/
    • ./
    • update host set key_file = null where key_file = '';
    • \q
    • If the DBmarlin server is running on Windows then use a cmd window and use psql.bat instead.
  • If you enable SQL Statistics collection for CockroachDB 21.1 or below if will show zeros for statement statistics.
  • If you are monitoring a server which requires TLS v1.0 or v1.1 which are now obsolete you will need to edit ./lib/security/ to change disabledAlgorithms and restart the DBmarlin Tomcat. See this FAQ for more details.
