High CPU usage detected on heysalad-ai-01 with 86.1% utilization and 1-minute load average of 6.887 across 8 cores. The top CPU consumer is the java process.

Suggested actions:

1. Investigate the java process (PID 1358737) as it is consuming the most CPU. Consider checking for runaway threads or memory leaks.
2. Monitor CPU load trends and check if the load average remains high over the next 15 minutes to decide if scaling or resource allocation changes are needed.
3. Notify the platform engineering team to review the high CPU usage and prepare for potential mitigation steps.

Decisions:

• The java process is confirmed as the primary CPU consumer.
• Immediate investigation and mitigation are required to prevent service degradation.

Next Steps:

• Analyze the java application logs and performance metrics to identify possible causes (e.g., infinite loops, memory leaks).
• Restart the java process during a low-traffic window to temporarily reduce CPU usage.
• Check recent deployments or configuration changes that might correlate with the CPU spike.
• Profile the java process using appropriate tools (e.g., jstack, VisualVM) to pinpoint bottlenecks.
• Evaluate the possibility of scaling resources or load balancing if the high CPU load is due to legitimate demand increase.
• Document findings and update incident tracking for further review by the engineering team.
