Unisphere Analyzer Must the Unisphere Analyzer

for VNX be running to collect

metrics?

No. VNX Block metrics are gathered through naviseccli commands.

VNX File metrics are gathered through CLI commands. However,

statistics logging must be enabled on each SP on VNX Block, and

statistics logging has a performance impact on the array. No

additional services are required for VNX File.
