All graphs stopped graphing at Thursday 8/16 midnight

I noticed this morning that all of my graphs stopped graphing data on 8/16 at midnight. Running ./validate.php yields the following results:

Component Version
LibreNMS 1.42.01-34-g731da95
DB Schema 258
PHP 7.0.30-0ubuntu0.16.04.1
MySQL 10.0.34-MariaDB-0ubuntu0.16.04.1
RRDTool 1.5.5


[OK] Composer Version: 1.7.1
[OK] Dependencies up-to-date.
[OK] Database connection successful
[OK] Database schema correct

I checked disk space and there is plenty left in the directory that is being used to store data. Also, looking through htop, the poller process is clearly running and gathering data

Run ./poller.php -d -h anydeviceaffected and pastebin the output

I’ll have to do this after I recover the vm and insure the problem wasn’t with a vmware side service. I just checked my machine in vsphere and it is hung up trying to consolidate its disk. As part of my troubleshooting I attempted to reboot the host, but it appears to have shutdown and is down and out for the moment.

This has been resolved, the hangup was due to vmware experiencing problems with disk consolidation. Once I shut the box down and had our VM admin disable/stop the hung up disk consolidation task, upon reboot the box was able to being displaying graphs seamlessly.
