argus-cache-snapshot

Simple node.js script for monitoring Argus cache size. The script uses node-cron to execute once every midnight. It will take a snapshot of cache.json file at CACHE_FILE_PATH. It will also measure size of distributor data directory at DATA_DIRECTORY_PATH. It will save results to OUTPUT_DIRECTORY_PATH. The cron schedule can be overriden using CRON_SCHEDULE env.
