Conditions/Threshold Example

Data nodes disk space (average) is consistently less 20% (or might be absolute value eg: > 1 gb) for the past 5min

Possible troubleshooting actions

• Optimize cluster for disk usage
• Implement ILM policies
• Delete older data/history that may not be needed
• Disable unused/unneeded replicas
• Add more data nodes
• Increase the disk size of the existing (data) nodes
