Monitoring/status page

[anarchivist]

Hydra depends on many services, but the site may have partial functionality if some of the services are missing/degraded. It would be nice to have a status page that showed if the application was set up correctly. This would include:

• Connection to Solr
• Connection to Fedora
• Connection to Redis
• Job queue depth and any failures
• Status of queue workers (how many are working?)
• FITS exists on configured path
• imagemagick exists on the configured path
• soffice exists on the configured path
• ffmpeg exists on the configured path
• It should warn if the minter state file is in the tmp directory.

"Minter state file"? I haven't run into this yet. Can you point me to a resource describing the meaning/significance of this?

@aeschylus You bet. Start here and let me know if you have any questions: https://github.com/projecthydra/sufia/blob/master/README.md#identifier-state
