Log Forwarding


Information:
Beta Access Required

This documentation describes support for log forwarding that is under active development and is available only to customers who have been individually approved as part of our Private Beta program.

To request an invite, submit this form.

Pantheon's Log Forwarding feature enables streaming operational logs from Pantheon sites directly into a centralized analysis tool (e.g., Splunk). This provides a critical, unified data stream for security, performance, and operational intelligence.

Access & availability

This feature is available to Private Beta participants at no additional cost. Submit this form to request an invite to participate.

Compatability

We currently support forwarding logs to the following providers:

If you rely on a provider other than Sumo Logic or Splunk, we want to hear from you! Please reach out to your Customer Success Manager (CSM) or our support team to voice your requirements.

Benefits

Integrating your Pantheon logs with your existing analysis tools allows your team to achieve a variety of critical goals:

  • Health Checks & Performance Monitoring: Proactively monitor application health, detect performance bottlenecks, and optimize resource usage.
  • Debugging & Root Cause Analysis: Accelerate the diagnosis and resolution of issues by correlating logs with other system data.
  • Security & Compliance: Perform security auditing, intrusion detection, and meet regulatory archiving requirements with a centralized view of all log activity.

Log Streams Forwarded

Pantheon forwards the following five binding-level log streams:
