An alert is saying a VM is low on disk space, but it isn't low on space
I have VMs that are alerting on low disk space, but when I go to Analysis | Capacity Remaining, everything is green. When I go to Troubleshooting | All Metrics, it says it has 24% left. I notice the alert hasn't updated since 11/30/2015. The metrics are from today, and show values for the past couple weeks. How do I get the alert to update again?
