The
Trusted Certificate Authorities
section lists the certificate authorities to use for
authentication of a Ranger Gateway connection. If the Ranger Gateway private key is not
signed by one of the trusted certificate authorities, the connection will be rejected. The
Add
Certificate Authority
section may be used to install additional trusted certificate authorities.
The certificate must be either an X.509 Certificate or a JKS Keystore format.
Root Cause
ZoneRanger includes a sophisticated root cause analysis service, which when triggered by status
polling failures, that determines which device is the root cause of the problem, and which
devices are impacted by the root cause device.
The root cause service divides root cause analysis into two categories: IP and TCP. The
Configuration > Root Cause
page is used to configure the reporting of IP and TCP root causes.
