Pods are ephemeral, log volumes are ephemeral, and the sheer volume of container stdout/stderr output can overwhelm simple log collection approaches. Kubernetes-native logging operators solve this problem by managing the entire log pipeline as Kubernetes resources — automatically discovering new pods, applying parsing rules, and forwarding logs to centralized storage. This guide compares three leading open-source Kubernetes logging operators: <strong>Fluent Operator</strong>, <strong>Loki Operator</strong>, and <strong>Vector Operator</strong>.</p> https://www.pistack.xyz/posts/2026-05-06-self-hosted-log-retention-lifecycle-management-elasticsearch-ilm-loki-opensearch-ism/ Wed, 06 May 2026 00:00:00 +0000 https://www.pistack.xyz/posts/2026-05-06-self-hosted-log-retention-lifecycle-management-elasticsearch-ilm-loki-opensearch-ism/ <p>Managing log retention is one of the most critical operational challenges for any self-hosted observability stack. Without proper lifecycle management, log indices grow unbounded, storage costs explode, and query performance degrades. Index Lifecycle Management (ILM), retention policies, and Index State Management (ISM) are the mechanisms that automate the movement, sizing, and deletion of log data across its useful lifetime.</p>
