Uncaught Exception When Accessing Alert API While Log DB is Down #111

Closed magneticstain closed 5 years ago

magneticstain commented 5 years ago

If the log DB (redis) is down, we should fail gracefully, as we do when the Inquisition DB (MySQL) is down.

Request:

GET /api/v1/alerts/

Response:

<br />

This also appears to generate an HTTP 500 error for the Stats API as well.

GET /api/v1/stats/
