For log collection.
Info
- No ingestion log format requirements.
- Index-free (somewhat).
- Meaning it indexes less data from log lines.
- This gives a smaller index file and faster ingestion, but slower querying.
- Specifically, the timestamp and a set of labels (key-value pairs) are indexed, but the content is unindexed.
- Prometheus-inspired query language.
- Typically uses Promtail for log collection from servers, sometimes with syslog-ng for log format conversion.
- Good integration with e.g. Kubernetes, Grafana and Prometheus.
Logging Challenges
- Privacy:
- Access control.
- Masking/de-identification of sensitive data.
- Re-identification of sensitive data, if required.
- Right to be forgotten.
- Right of access.
- Retention period.
