after upgrading to Grafna 7 i got that error:
t=2020-10-09T15:09:37+0100 lvl=info msg=“Registering plugin” logger=plugins name=“Boom Table”
t=2020-10-09T15:09:37+0100 lvl=eror msg=“Failed to read plugin provisioning files from directory” logger=provisioning.plugins path=/etc/grafana/provisioning/plugins error=“open /etc/grafana/provisioning/plugins: no such file or directory”
This happens to me, because I update my grafana from grafana repo. So, I have fixed by creating by hand these directory and sample.yaml file.
As root user:
mkdir /etc/grafana/provisioning/plugins/
vim /etc/grafana/provisioning/plugins/sample.yaml
Paste these text:
# # config file version
apiVersion: 1
# apps:
# - type: grafana-example-app
# org_name: Main Org.
# disabled: true
# - type: raintank-worldping-app
# org_id: 1
# jsonData:
# apiKey: "API KEY"
Then, change your file permissions
chown -R root:grafana /etc/grafana/provisioning/plugins/
Finally restart your grafana server and all have to be working perfectly!
