Troubleshooting Known problems - exasol/nagios-monitoring GitHub Wiki

• on Windows docker hosts you need to start your command line prompt (CMD.EXE) with administrator privileges, otherwise pulling the image won't work properly

• if you got an error like "WARNING - internal error <Fault -1: 'Volume could not be found'>" from check_db_diskspace plugin please check your permissions on the EXAStorage volumes and make sure that you didn't change the system labels of those volumes (create own labels if you want to tag them instead of renaming the given ones).

• Nagios shows the follwing error message for the check_db_performance.py plugin: CRITICAL "('08S01', '[08S01] [unixODBC][EXASOL][EXASolution driver]No server listening. (-1) (SQLDriverConnect)'). This error occours, if you use more than one public interfaces. You can use the following workaround to fix this:

1. connect to license server via SSH
2. from there connect to a database node (like n11) and create /etc/exawolke directory: (mkdir -p /etc/exawolke)
3. create the file "public_interface" (by using 'echo eth0 >/etc/exawolke/public_interface')
4. copy this file on all nodes (can be done by using the following command: "cos_sync_files /etc/exawolke/public_interface")
5. restart EXAoperation via EXAoperation Web Interface
