Introduction
Mistral is a powerful tool designed to report on and resolve I/O performance issues encountered when running complex Linux applications on high-performance compute clusters. Originally developed by Ellexus, now an Altair company, Mistral enables users to monitor application I/O patterns in real-time. It allows for the logging of undesirable behavior through the use of rules defined in a configuration file known as a contract.
Key Features
- Contract Configuration: Define I/O limits and rules for processes using contract files.
- Log Entries: Detailed logging of I/O events, including violations and performance metrics.
- Traffic Light Log: Categorizes I/O operations into good, medium, and bad based on defined rules.
- Scheduler Integration: Seamless integration with various job schedulers like IBM Spectrum LSF, OpenLava, Univa Grid Engine, Slurm, and PBS Professional.
- Container Support: Monitors workloads within Singularity containers.
- Mistral Healthcheck: Tools for analyzing log data to generate reports and graphs.
- Troubleshooting: Guidance on disabling monitoring for specific binaries and resolving common issues.
