The above command is an example of how to execute the Show CPU Usage command on a Fortigate device. The output will display detailed information about the CPU usage.

Interpreting the Output

The output of the Fortigate Show CPU Usage CLI command provides valuable insights into the CPU utilization on the device. Here are some key elements to consider when interpreting the output:

• CPU utilization percentage: This indicates the overall CPU utilization at the time of execution. Lower percentages represent lower CPU load, while higher percentages indicate higher load.
• Processes consuming the most CPU resources: This section lists the processes or tasks that are utilizing the most CPU power. Identifying resource-intensive processes can help administrators investigate the root causes of performance issues.
• Overall CPU load: This provides information about the distribution of CPU load across different system components, such as user processes, kernel processes, interrupts, and idle time. It helps administrators understand which components are the most resource-intensive.

By analyzing these elements, network administrators can identify anomalies, troubleshoot performance bottlenecks, and optimize the CPU usage on their Fortigate devices.

Best Practices for Monitoring CPU Usage

To effectively monitor CPU usage on Fortigate devices, here are some best practices to consider:

• Regular monitoring: Continuously monitor the CPU usage to detect any patterns, spikes, or abnormalities that may indicate performance issues or security threats.
• Baseline establishment: Establish a baseline of normal CPU usage under typical operating conditions. This baseline will serve as a reference point for detecting deviations and abnormal behavior.
• Threshold setting: Set thresholds for CPU utilization percentages to receive alerts when the CPU load exceeds certain predefined values. This helps administrators proactively address potential performance issues.
• Process analysis: Regularly analyze the processes consuming the most CPU resources and investigate their impact on the overall system performance. Optimize or mitigate resource-intensive processes when necessary.

Another Aspect of Fortigate Show CPU Usage CLI

In addition to monitoring CPU usage, Fortigate Show CPU Usage CLI also provides the capability to view historical CPU usage data. This feature allows network administrators to analyze trends, identify patterns, and make informed decisions regarding system optimization and resource allocation.

Syntax for Viewing Historical CPU Usage Data

The syntax for viewing historical CPU usage data with the Fortigate Show CPU Usage CLI command is as follows:

diagnose sys cpu-history

This command provides a historical overview of the CPU usage on the Fortigate device, allowing administrators to observe trends over a specified period.

The command output includes information such as the CPU utilization percentages for different time intervals, system temperature, and memory usage. Administrators can use this data to analyze CPU workload patterns, identify peak utilization periods, and optimize system performance accordingly.

Example:

Fortigate# diagnose sys cpu-history

Above is an example of how to execute the command to view historical CPU usage data on a Fortigate device. The output will display detailed historical data, allowing administrators to analyze trends.

Best Practices for Analyzing Historical CPU Usage Data

Analyzing historical CPU usage data is a valuable component of proactive system optimization and capacity planning. Here are some best practices for effectively analyzing historical CPU usage data on Fortigate devices:

• Data retention: Configure appropriate data retention policies to retain historical CPU usage data for a sufficient period. This enables administrators to observe trends over a meaningful timeframe and plan system upgrades or resource allocation adjustments.
• Granularity selection: Choose the appropriate time interval for data collection to balance resource utilization and data granularity. Collecting data at shorter intervals provides more detailed insights but may increase system overhead.
• Trend analysis: Analyze trends and patterns in historical CPU usage data to identify recurring workload peaks or specific timeframes with increased resource demands. This analysis facilitates capacity planning and system optimization.

By closely monitoring and analyzing historical CPU usage data, network administrators can proactively optimize system performance, allocate resources efficiently, and avoid potential performance bottlenecks.

In conclusion, the Fortigate Show CPU Usage CLI command provides essential insights into the CPU performance of Fortigate devices. By utilizing this command, administrators can monitor real-time CPU usage and historical trends, identify potential performance issues, and optimize system resource allocation. Regular monitoring and analysis of CPU usage data play a crucial role in ensuring optimal system performance and network security. Implementing best practices for CPU usage monitoring and analysis enables administrators to proactively address performance bottlenecks and make informed decisions regarding system optimization.
