The Device Health dashboard shows you the cumulative health status
and performance of your deployment based on the health scores of the onboarded NGFWs.
The device health is determined by the severity of the health score (0-100) and its
corresponding health grade (good, fair, poor, critical). The health score is calculated
based on the priority, quantity, type, and status of the open alerts.
Here is an example how you can optimize device performance using the Device
Health dashboard.
As a network administrator for a large enterprise, you've been tasked with
improving the overall health and performance of your firewalls. Your goal is to
proactively identify and address potential issues before they impact network
operations.
By following the below task-based approach, you'll leverage the Strata Cloud
Manager's Device Health features to maintain a high-performing
and reliable network infrastructure, minimizing downtime and enhancing overall security
posture.
Access the Device Health dashboard in Strata
Cloud Manager to get an overview of the health status of your firewalls.
Review the Health Score for each firewall, focusing on devices with
scores below 80, which indicate potential issues.
Analyze the Device Health Statistics to identify specific areas of
concern, such as high CPU usage, memory utilization, or session count.
Examine the Device Health Score Trend over the past 30 days to spot any
recurring patterns or gradual declines in performance.
For firewalls with consistently low health scores or declining trends,
drill down into the detailed metrics to pinpoint the root causes.
Develop and implement a remediation plan for the affected devices,
which may include:
Optimizing security policies
Upgrading hardware for overutilized devices
Adjusting network configurations to balance traffic load
After implementing changes, continue monitoring the Device
Health dashboard to verify improvements and ensure sustained
optimal performance.
