This wikipage gives some details about the "Files Monitoring" software.

Objectives

The objectives of the "Files Monitoring" software are:

• Make sure that nebulous doesn't lose any OTA
• Provide statistics about the storage nodes usage

Implementation

• The software is still installed and run as schastel. TODO: Move it to ippm
• The source code is in ~schastel/dev/FilesMonitoring. In the rest of this documentation, all paths are relative to it. TODO: SVN it
• On each storage node, every hour, the NodeRelated/refresh_table.py script is started (from the crontab file defined in NodeRelated/deployment/scripts/crontab.<node name>). To prevent cluster/nfs overwhelming, the scripts are not run at the same time. The crontab files as well as the deployment script can be generated from NodeRelated/deployment/generate_crontabs_and_deployment_script.py. Run it and follow its (last) instruction to deploy. Note that error messages are currently sent to schastel@ifa.hawaii.edu.
