I’ve started on a “package” for monitoring Nextcloud logs with CrowdStrike’s Falcon LogScale (full disclosure: I work for CrowdStrike).
Falcon LogScale is a super-fast and affordable log management solution. LogScale is a commercial product, however, it does have a free “Community edition”. A limitation of the community edition is a sliding 7-day data retention window.
