Monitoring Socket with Vigilmon: API Health, Webhook Delivery & Supply Chain Security Uptime

Socket is a supply chain security platform that detects malicious npm, PyPI, and other package ecosystem threats before they reach your codebase. It analyzes packages for hidden network calls, shell command execution, typosquatting, obfuscated code, and dependency confusion attacks — and blocks them via GitHub PR integration, CI gates, and CLI checks. When Socket's API is degraded, PR status checks stop appearing on pull requests, developers can't see package risk scores, and new dependencies get merged without automated security analysis. Vigilmon gives you external visibility into Socket's API availability, webhook delivery health, and the dashboard your security team uses to review flagged packages.

What You'll Build

• A monitor on Socket's API health endpoint to detect service degradation
• A webhook endpoint monitor to catch delivery failures before they silently break PR checks
• An SSL certificate monitor for Socket's domain
• An alerting setup that tells you when supply chain analysis is offline

Prerequisites

• A Socket account at socket.dev with API access configured
• Socket's GitHub App installed on your repositories
• A free account at vigilmon.online

Step 1: Verify Socket's API Availability

Socket exposes a public status and API surface. The primary API endpoint used by CLI, GitHub App, and integrations is at api.socket.dev. You can probe it directly:

curl -I https://api.socket.dev/v0/

A healthy Socket API returns 200 or 401 depending on authentication. Either response confirms the API layer is up and routing requests correctly.

Step 2: Create a Vigilmon HTTP Monitor for the Socket API

1. Log in to Vigilmon → Add Monitor → HTTP.
2. URL: https://api.socket.dev/v0/.
3. Check interval: 60 seconds.
4. Response timeout: 15 seconds.
5. Expected status: 200.
6. Label: Socket API.
7. Click Save.

This monitor catches:

• Socket API outages that prevent all package analysis (CLI, GitHub App, CI integration)
• Partial API degradation where requests time out or return 5xx errors
• Routing or infrastructure failures on Socket's backend
• Disruptions that would cause GitHub PR checks to hang or fail silently

Alert sensitivity: Set to trigger after 2 consecutive failures to avoid noise from transient network blips.

Step 3: Monitor the Socket Dashboard

The Socket dashboard at socket.dev is where security teams review flagged packages, manage policies, and investigate alerts. Dashboard availability is separate from API availability — a frontend failure can block manual review without affecting automated checks:

1. Add Monitor → HTTP.
2. URL: https://socket.dev.
3. Check interval: 5 minutes.
4. Response timeout: 15 seconds.
5. Expected status: 200.
6. Keyword: Socket.
7. Label: Socket dashboard.
8. Click Save.

Step 4: Monitor Socket's GitHub Integration Endpoint

Socket's GitHub App posts PR comments and status checks by calling back to its own API. If Socket's outbound webhook processing is degraded, you'll see:

• No status check on pull requests after a new dependency is added
• Missing "Added packages" or "Removed packages" PR comments
• Security policy blocks not appearing on PRs

To validate Socket's GitHub integration surface is up, monitor the endpoint GitHub uses to send webhook events to Socket:

curl -I https://api.socket.dev/v0/github/

1. Add Monitor → HTTP.
2. URL: https://api.socket.dev/v0/github/.
3. Check interval: 2 minutes.
4. Response timeout: 15 seconds.
5. Expected status: 200.
6. Label: Socket GitHub integration.
7. Click Save.

If Socket's GitHub webhook endpoint goes down, GitHub queues webhook deliveries for retry. PR checks will be delayed rather than permanently lost, but developers will be blocked waiting for status checks to clear.

Step 5: Monitor SSL Certificates

Socket's security product must itself be secure. An expired or invalid SSL certificate on api.socket.dev or socket.dev would cause:

• CLI tool failures (socket scan returns TLS errors)
• GitHub App webhook delivery failures
• Browser security warnings blocking dashboard access

1. Add Monitor → SSL Certificate.
2. Domain: api.socket.dev.
3. Alert when expiry is within: 30 days.
4. Alert again: 14 days, 7 days, 3 days, 1 day.
5. Click Save.

Repeat for socket.dev:

1. Add Monitor → SSL Certificate.
2. Domain: socket.dev.
3. Alert when expiry is within: 30 days.
4. Click Save.

Step 6: Set Up a Canary PR Check Monitor

If you want to detect Socket PR check failures end-to-end — not just API availability — you can add a monitor that hits a specific Socket report URL for a known package risk check. This validates the full analysis pipeline, not just API routing:

# Example: check Socket's report for a specific npm package
curl https://socket.dev/npm/package/lodash/overview

1. Add Monitor → HTTP.
2. URL: https://socket.dev/npm/package/lodash/overview.
3. Check interval: 10 minutes.
4. Expected status: 200.
5. Keyword: lodash.
6. Label: Socket package analysis pipeline.
7. Click Save.

This catches analysis pipeline failures that don't show up in basic API availability checks.

Step 7: Configure Alerting

In Vigilmon under Settings → Notifications, configure your alert channels:

| Monitor | Trigger | Action | |---|---|---| | Socket API | Non-200 or timeout | PR checks will stop; alert security team and dev leads | | Socket dashboard | Non-200 or keyword missing | Manual review blocked; check Socket status page | | GitHub integration | Non-200 | PR status checks failing; developers blocked on merges | | SSL (api.socket.dev) | < 30 days to expiry | CLI and GitHub integration will break on expiry | | SSL (socket.dev) | < 30 days to expiry | Dashboard access blocked on expiry | | Package analysis canary | Non-200 or keyword missing | Full analysis pipeline degraded |

Alert channels: Route Socket API and GitHub integration alerts to your security team Slack channel. Route SSL certificate alerts to your platform team.

Common Socket Failure Modes and What Vigilmon Catches

| Scenario | Vigilmon monitor | |---|---| | Socket API outage | API monitor fires within 60 s; all PR checks stop | | Dashboard frontend down | Dashboard monitor fires; automated checks unaffected | | GitHub webhook processing degraded | GitHub integration monitor fires; PRs queue without checks | | SSL certificate expiry | SSL monitor alerts at 30 days; CLI and GitHub App break | | Package analysis pipeline failure | Canary monitor fires; PRs show outdated or missing analysis | | DNS disruption for socket.dev | All monitors fire simultaneously | | CDN outage affecting Socket's edge | API and dashboard monitors fire | | Rate limiting affecting your org | API returns 429; monitor fires if you've set expected status to 200 |

Socket's value is in the continuous, automated analysis it applies to every PR — but that analysis is only effective when the service is running. Vigilmon gives you external visibility into Socket's API health, GitHub integration endpoint, package analysis pipeline, and SSL certificates so your security team knows the moment automated supply chain analysis goes offline.
