Requirements¶

MongoDB¶

MongoDB has to be installed and a replica set configured prior to the installation of PLOSSYS Output Engine. We recommend to use MongoDB as of version 7.0.0. For how to install and configure MongoDB, refer to the SEAL-specific MongoDB documentation.

Hint - older versions

MongoDB 4.4.4 works with Local Spooler 6.1.3 but has reached its end of life date in February 2024. Refer to MongoDB Software Lifecycle Schedules.

SEAL NATS¶

The SEAL NATS message broker as of version 2.10.0 has to be installed.

Hint - separate installation

For more information about the SEAL NATS installation, refer to the SEAL NATS documentation.

SEAL Logrotate¶

As of version 6.1.3, the seal-logrotate service is no longer included in the installation of Local Spooler. The service cleans up outdated log files to free up storage space and prevent performance and memory issues. You can run Local Spooler without Logrotate, but we strongly recommend to install it. When running a cluster, this should be done on each server. For more information, refer to SEAL Logrotate documentation.
