Monitoring Tools (Additional Content)

1. HealthCheck – Automating Cluster Health Checks & Log Analysis

HealthCheck is a built-in tool that performs diagnostics on PowerScale clusters, identifying issues related to hardware, network, and system components.

Automating HealthCheck Execution

Instead of running HealthCheck manually, administrators can schedule it to run automatically at regular intervals.

isi healthcheck schedule set --interval=24h

• This schedules HealthCheck to run once every 24 hours for proactive monitoring.

Viewing Detailed HealthCheck Logs

isi healthcheck view --detail

• Displays detailed diagnostic reports, including:
  • Disk health
  • Network status
  • Node connectivity
  • File system integrity

Common HealthCheck Alerts & Resolutions

Alert Type	Possible Cause	Recommended Action
Degraded Disk	Disk nearing failure.	Replace disk immediately to prevent data loss.
Network Issue	Port blockage, switch failure.	Check switch logs & verify VLAN configuration.
Node Down	Hardware failure, power issue.	Restart node & check power supply.
