ezelkow1 opened a new pull request #3104: Add monitoring.json snapshotting
URL: https://github.com/apache/trafficcontrol/pull/3104
 
 
   These changes are to fix the issue of the monitoring.json and crconfig's being out of sync. Currently it is possible to make a change to a status (or other field that the monitoring.json presents) and have it show up
   immediately while the changes are not reflected in a crconfig until it has been snapshotted, causing an inconcsistency across the files.
   
   This will change the column name in the snapshot table from 'content' to 'crconfig' and then add a new column 'monitoring'. When a snapshot is done we then store both the crconfig and monitoring.json in the table at
   the same time, maintaining consistency. Monitoring.json is then pulled from the table instead of being generated on the fly like was done previously.
