Send Gemini CLI telemetry — traces, metrics, and logs — to Last9 via OpenTelemetry. Two paths documented: - Direct: GEMINI_TELEMETRY_* env vars set endpoint; standard OTEL_EXPORTER_OTLP_HEADERS provides auth (picked up by underlying OpenTelemetry JS SDK even though gemini-cli does not pass headers explicitly to its OTLP exporters). - Local OTel Collector: useful for batching or fan-out. Traces are opt-in via GEMINI_TELEMETRY_TRACES_ENABLED=true. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Demonstrates dual-pipeline filterprocessor approach for handling delta and cumulative OTLP metrics across multi-replica collectors: - nginx round-robin simulates K8s Service load-balancing - filter/keep_delta + setshardkey + deltatocumulative per-pod isolation - filter/keep_cumulative passthrough (SDK owns the counter) - metrics/delta_broken pipeline shows undercount without setshardkey - verify.sh queries local VictoriaMetrics for series count sanity check Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
…usions - Replace split mounts with single /:hostfs:ro,rslave to prevent ENOENT errors when hostmetrics prepends /hostfs to /proc/mounts paths - Add exclude_fs_types for squashfs/snap/tmpfs/overlay to eliminate snap loopback noise without per-revision exclusion rules - Fix exclude_mount_points patterns to match new single-mount layout - Bump image to otel/opentelemetry-collector-contrib:0.144.0 - Update process: scraper comment to document TOCTOU limitation - Add comment on when to use network_mode: host for prometheus scraping Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
