Next, +Netdata should be re-installed from the source.

The user running the Agent +(typically `netdata`) needs read access to `google_cloud_credentials.json`, which you can set with +`chmod 400 google_cloud_credentials.json; chown netdata google_cloud_credentials.json`. Set the `credentials file` +option to the full path of the file. + +[](<>) |
