Intelligence/CLI

Your monitoring data, for you and your coding agent.

The AppSignal CLI puts your errors, logs, and performance data in the terminal, for you and for any agent that can run a shell command. See what broke, read the logs around it, and close it out.

Stay in your terminal

Check errors, read logs, and close issues from the place you already work. No tab switching.

Works with your agent

Any agent that can run a shell command can use it. Claude, Codex, and OpenCode get a ready-made skill.

Simple to set up

One install command, sign in with your AppSignal account, and you're looking at production data.

What you can do

Your errors, logs, and alerts, in your terminal.

Same errors, logs, and alerts as the web app and the MCP server. Find what broke, act on it, and get back to work, without leaving the terminal.

Errors

See which errors, slow requests, and metric spikes are open right now. Assign one to a teammate, set its severity, leave a note, or close it out.

Logs

Watch your logs live, or search back through them. Filter by severity or source, reuse your saved views, and turn log lines into metrics and alerts.

Traces

Open the trace behind any error, filter by tag or deploy, and see where the time went, step by step.

Alerts

Create, update, and retire alerts on any metric, like CPU or response time, before a spike turns into an outage.

Dashboards

List your dashboards, create a new one, or update an existing one, without clicking through the app.

Agent skill

A skill for Claude, Codex, and OpenCode is included. Install it once and your agent knows when to reach for the CLI and how to read what it returns.

For coding agents

Let your coding agent debug production.

Point your agent at a failing request and it can look up the error, read the logs around it, and propose a fix. Every command can return JSON, so agents and scripts read it too. You review. They do the digging.
