ezelkow1 opened a new pull request #3053: Traffic Monitor Disk Support
URL: https://github.com/apache/trafficcontrol/pull/3053
 
 
   With these changes traffic monitor will create TM and CR backup files on disk. If TO is unreachable and these files exist then it will pull its data from these files. Any time a new valid one is available it will write them back to disk. On startup TM will still follow its exponential backoff scheme but once it hits the max it will create a non-authenticated TO session so that we can use the disk files. If at any point TO comes back up then TM will attempt to authenticate and continue as normal
   
   This depends on #3045
