The DRS Dump Insight web app takes existing drmdump log files (each drmdump log file contains the actions proposed and taken by DRS within a certain time or file size) and provides a summary of the DRS run, along with changes in host resource consumption in a plain text format.
With this tool, you can answer questions like:
- What recommendations did DRS drop due to cost/benefit analysis?
- Why did DRS make a certain recommendation?
- Why is DRS not making any recommendations to balance my cluster?
- How is my custom affinity/anti-affinity rule affecting load balancing in my cluster?
- Can I get all the recommendations made by DRS?
How does this tool work? DRS Dump Insight:
- Automates dump replay (with pre-built custom DRS replayers)
- Uses custom replayers to give additional info not available in regular replayer logs (like recommendations dropped due to rule conflicts)
- Parses and analyzes a custom replayed log to get insight into DRS decisions
- Generates a final summary in a plain text format
