## Command Center Dashboard Overview
Command Center’s main dashboard was designed to provide Zadara cloud administrators
with a centralized viewpoint on their cloud utilization, and
to perform cloud level operations.
The dashboard has four main panels, each monitoring a different key aspect
of the cloud infrastructure:
- The **Resource Utilization** panel provides a birds-eye view on the core
cloud resources utilization, such as VCPUs, memory, disks etc.
- The **Network Activity** panel provides monitoring data for real-time
network throughput and utilization.
- The **Drive Utilization** panel provides a breakdown of drives by their
model and utilization per drive.
- The **IP Address Utilization** panel displays the defined IP ranges for
frontend, backend and heartbeat networks, the allocation and the level of
utilization for each range.
- The **Default Cloud Certificates** panel lists the certificates per domain,
the certificate’s start and expiration dates, and certificate issuer.
