Hello ,
I've also got a similar problem with Harvest 1.3 with a cluster recently upgraded to Ontap9.1P1.
Harvest and Grafana seems to work fine... Everything seems correct but :
Every hour I've got a security.invalid.login [ALERT] , username: netapp-harvest, application: ontapi.
But the collect seems to be OK .
Some log :
