Roadmap

Find a brief overview of what is planned:

• add time support in threshold, ex.: warn=time > 18:00 && load > 10
• open telemetry
• improve configuration
  • add config validator
  • use strong typed config items
  • add module enable/disable option directly in the module section

Not gonna happen

• CheckMK support
• Embedded LUA support
• Embedded Python support
• Graphite support
• NRDP support
• NSCA support
• SMTP support
• Website/Rest API (except doing checks)
• check_nt support
