  • Log Based Metrics, from different types and apply them to log messages with specific labels.
  • Log Exports, that send them to Cloud Storage (buckets) or Cloud Pub/Sub (log streaming).
  • Log Alerts.
  • Avanced Analytics with BigQuery.
  • Log retention for 30 days or longer with Cloud Storage.

Logs

  • Agent logs.
  • Logs available in Stackdriver Logging

Ingestion

  • Integration with different GCP products, services and audit logs, Splunk, AWS.
  • All logs are stored into with same structure, a LogEntry, but they can have different payloads.

Stackdriver Trace

Stackdriver Trace is a distributed tracing service that collects latency data for finding performance bottleneck in production apps in Google App Engine, HTTP Load Balancer and applications that use Stackdriver SDK.

  • Latency shift detection.
  • No need to provide credentials in Google Cloud Platform:
    • Enabled in Googled App by default.
    • It can be enabled in Google Kubernetes Engine on creating cluster (by adding trace.append).
