Conversation
📝 WalkthroughWalkthroughThe change adds environment-driven selection of InfluxDB, InfluxDB 2, and Elasticsearch. Docker Compose now provides profiled services for InfluxDB 2, Telegraf, and Elasticsearch with persistent volumes. Telegraf routes UDP metrics to InfluxDB 2. Documentation covers the new settings and profiles. Tests verify resolved Compose services for each backend. Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟠 High · up to When the Elasticsearch profile is enabled, monitoring data is accessible without authentication, and non-default InfluxDB 2.x endpoint or UDP settings can cause writes to fail or reach the wrong instance. These production-facing configuration risks should be addressed before merging. Sequence Diagram(s)sequenceDiagram

🗄️ Data Integrity & Integration | 🟠 Major | 🏗️ Heavy lift
Honor the configurable InfluxDB 2.x endpoint and UDP port.
images/common/openwisp/settings.py honors INFLUXDB2_HOST, INFLUXDB2_PORT, and TIMESERIES_UDP_PORT. This file fixes the listeners to 8089 and 8090 and fixes the output URL to http://influxdb2:8086. If an operator overrides these settings, UDP writes fail or are stored in a different InfluxDB instance than HTTP writes.
Pass the relevant values through docker-compose.yml, parameterize this configuration, and add a regression test with nondefault host or port values.
As per path instructions, tests must cover relevant success, error, boundary, and unusual input scenarios.

🔒 Security & Privacy | 🟠 Major | 🏗️ Heavy lift
Do not disable Elasticsearch security in the default service.
When the elasticsearch profile is enabled, xpack.security.enabled=false permits every container on the Compose network to read and modify monitoring data without authentication. A compromised peer container can alter or exfiltrate this data. Enable Elasticsearch security and configure the backend credentials or API key before enabling this service.
As per path instructions, flag potential security vulnerabilities.

Document INFLUXDB2_URL and its precedence.
images/common/openwisp/settings.py uses INFLUXDB2_URL when it is set and otherwise builds a URL from INFLUXDB2_HOST and INFLUXDB2_PORT. Add this setting and state that it takes precedence. Operators otherwise cannot discover the supported custom URL configuration.
As per path instructions, documentation must remain consistent with implemented behavior.
