CMRESHandler
Elasticsearch Log handler for the logging library
Decision gist · record as of 2026-08-14
Yes, if you are already running Elasticsearch and need a lightweight Python logging handler to send logs directly to it. No, if you require active maintenance or support for modern Elasticsearch versions—the package is dormant since 2017-10-08 and has not been updated to verify compatibility with current Elasticsearch releases. Consider it a stable but unsupported tool; test thoroughly with your Elasticsearch version before production use.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires a running Elasticsearch server accessible at the configured host and port; optional dependencies (requests-kerberos, requests-aws4auth) needed only for Kerberos or AWS IAM authentication.
- Low install friction with pure-Python wheels available for both Python 2 and 3.
- However, the package is dormant—last release was 2017-10-08 and no commits since 2024-06-06.

What it is and what it does
CMRESHandler is a logging handler that bridges Python's standard logging library and Elasticsearch, allowing you to send log records directly to Elasticsearch indices instead of (or in addition to) files or stdout. It wraps log entries as JSON documents and buffers them before flushing to Elasticsearch, supporting optional authentication (basic, Kerberos, AWS IAM) and SSL encryption.
The handler integrates with Django logging configuration and lets you attach custom fields to individual log records for instrumentation—for example, timing metrics or request IDs—which then become queryable fields in Elasticsearch. It preserves standard logging metadata like exception tracebacks, method names, and line numbers, making it useful for centralized log aggregation and analysis.
Use it for
- Centralize application logs from multiple Python services into a single Elasticsearch cluster for unified search and analysis.
- Instrument Django applications to log database query times and SQL statements alongside application events for performance monitoring.
- Add custom fields to logs on a per-message basis to enable rich filtering and aggregation in Elasticsearch.
- Replace file-based logging with Elasticsearch to avoid log rotation and disk management overhead in containerized environments.
- Combine Elasticsearch logging with other handlers to send critical errors to files while routing all logs to Elasticsearch for analysis.
