Pandora FMS server automatically stops when it can not connect to MySQL Server. If the Pandora FMS server is not running, the packages are still stored in the input directory (
/var/spool/pandora/data_in ) as long as the Tentacle server remains active.
All the remote monitoring configured will be kept stopped until the Pandora FMS server is started again. When the Pandora FMS server is restarted it will process these packages and no data will be lost.
