<?php // Example of optimizing ELK Stack costs through indices management $retentionPeriod = '30d'; // Retain logs for 30 days // Delete old indices system("curl -X DELETE 'http://localhost:9200/logs-".date("Y-m-d", strtotime($retentionPeriod))."*'"); // Optimize resources system("curl -X PUT 'http://localhost:9200/_cluster/settings' -H 'Content-Type: application/json' -d '{ \"transient\": { \"cluster.routing.allocation.enabled\": \"all\" } }'"); ?>
