Signal is available on all Arize AX plans. Free includes 10 issues per month; Pro includes 25. Enterprise includes unlimited issues, plus repo-backed fix PRs and custom agent integrations. Through September 15, 2026, Signal and managed agents are included at no additional charge for Enterprise. See Pricing and usage.
Signal is a built-in worker that scans a tracing project’s traces on a schedule, groups recurring failure patterns into issues, and writes an investigation for each one (overview, trace evidence, suggested fix).

The Signal tab in an Arize AX project with the option to enable Signal

Requires a tracing project with traces in Arize. See Set up tracing if needed.
No repo or extra skills are required to detect issues. Free and Pro get Signal issue detection only—they cannot attach a repo, open fix PRs, or choose a custom agent integration.

​
Availability

Limits are account-wide and reset each calendar month (UTC). When Free or Pro reach the monthly cap, Signal pauses new runs until the next month or until you upgrade. The ability to purchase additional Free or Pro issues is coming soon.

​
Enable Signal

1

Open the tracing project

Signal only reads traces from the selected project.
2

Open the Signal tab

Select Signal in the project navigation.
3

Click Enable Signal

Arize creates a default automation using the Signal preset (for example, every 10 minutes). On Enterprise, you can choose which agent integration runs Signal instead of the Arize-managed default. The tab stays linked to this automation until you disable Signal or delete it.

​
Read issues

The Signal tab shows issue volume over time, a breakdown by entity when tagged, and a ranked issue list. Select an issue to read its investigation:
  • Overview: summary of the failure pattern
  • Evidence: trace IDs and filters
  • Proposed fix: suggested prompt, code, config, or eval change
Click the example traces to open evidence in Explore your traces.

​
Configure Signal

Use Configure Signal to change how often Signal runs and add extra context for the agent. On Enterprise, you can also attach a GitHub repo so Signal can open pull requests for proposed fixes.
1

Open Configure Signal

On the Signal tab, open the ⋯ menu in the tab header and choose Configure Signal.
2

Set cadence and context

Choose how often Signal reviews recent traces, and optionally add additional context for the agent.
3

Attach a repo (Enterprise)

Enable Attach Repo, choose an existing GitHub skill or create one (name + personal access token), and enter the repository as owner/repo. See Skills and permissions for token scopes.
4

Save

Click Save. When you attach a repo, Arize creates or updates the Signal agent preset for this project automatically—you do not need to visit Agent Presets first. To return to trace-only mode, clear the repo or reset the Signal agent config in the same dialog.
