Storage event reporting and monitoring - PoC

In the previous blog post we have presented a proposal for reporting and monitoring storage-related events using journald and structured logging. To test if the proposal is viable we need some proof of concept. Such a PoC should demonstrate the complexity of the proposed solution as well as the sufficiency of the proposed set of stored (logged) items and the catalog entry.

Reporting and monitoring storage events

With any type of storage failures and errors happen. Depending on the setup and the their extent such failures and errors might be anything from mere annoyance to critical import. However, they all have one thing in common -- they need to be properly reported so that counter-actions and fixups (e.g. replacing a failed drive, restoring data from a backup, etc.) can happen.
