The OpenTelemetry demo ships with three storage backends: Jaeger for traces, OpenSearch for logs, Prometheus for metrics.

I swapped all three for one GreptimeDB standalone. The collectors didn't change , only the write address moves.

#OpenTelemetry

Reference architecture diagram in four columns. Sources: Application (OTel SDK), Hosts / middleware (exporter), Log files. Collection: OTel Collector (OTLP), Prometheus (remote write), Vector / Fluent Bit (Loki push / ES bulk). All three collection paths converge on a single GreptimeDB box containing Frontend, Metasrv, Datanode, Flownode and Object storage, labelled "metrics, logs, traces in separate tables, one engine". Two arrows leave it: Dashboards and alerts (Grafana, PromQL / SQL), and Investigation and analysis (SQL, agent, Jaeger API).

oss-sec: CVE-2026-24012: Apache IoTDB: Denial of Service via Resource Exhaustion in Aggregation Query

Posted by Haonan Hou on Jul 06 Severity: moderate Affected versions: - Apache IoTDB 1.3.3 before 2.0.8 Description: Uncontrolled Resource Consumption vulnerability in Apache IoTDB. Some interface fails to impose reasonable limits on the time span and aggregation interval of the query. An attacker can construct a request with extreme parameters (e.g., a very large time range combined with a minimal interval). This forces the DataNode to build an enormous result set...
