Access Control

  • Other administrators remain restricted to their active group and assigned memberships.

    • Servers
    • Agents
    • Monitoring checks
    • Regions and countries
    • SSH credentials
    • Installation tasks
    • User and group management
  • Removed agent UUIDs from regular API responses.
  • Prevented cross-group access through mismatched server IDs, IP addresses, or agent IDs.

  • Added configurable JWT signing using RS256 or HS256.
  • Reduced the default JWT lifetime to one hour.

  • Fixed access validation for agent status, uptime, version, scheduler, and check endpoints.
  • Improved credential selection so users only see shared credentials or credentials available to their group.
  • Added safer handling of invalid or inaccessible resources.

Operations

  • Added a dedicated scheduler process entry point.
  • The embedded scheduler can be disabled with RMON_SCHEDULER_ENABLED=0.
  • Added configurable public URL support for deployments behind a reverse proxy: RMON_PUBLIC_URL=https://rmon.example.com.
  • Added configurable paths for Flask and JWT keys.
  • Added secure automatic generation of the Flask session secret when no explicit secret is provided.

RMON Server 6.33 / Agent 1.20

Improvements
  • Improved result delivery reliability:
    • Automatic retries for temporary server errors.
    • Correct failover between multiple RMON servers.
    • Reliable cleanup of delayed-result queue locks.
  • Manual executions of the same check can now run independently without scheduler conflicts.
  • Server and agent APIs now validate incoming payloads and return clear errors for invalid requests.
