Advanced Monitors

Specialized monitoring for complex infrastructure

Monitoring

ATStatus provides advanced monitoring capabilities for specialized infrastructure including containers, cloud services, APIs, and custom script-based checks.

Advanced Monitor Types

Docker Container

docker

Monitor Docker container health and status via the Docker API.

• Container running state
• Health check status
• Resource usage metrics

Kubernetes

kubernetes

Monitor Kubernetes deployments, pods, and services.

• Pod health and readiness
• Deployment status
• Service endpoints

gRPC Health

grpc

Monitor gRPC services using the standard health checking protocol.

• gRPC health check protocol
• Service-specific health
• TLS support

GraphQL

graphql

Monitor GraphQL APIs with custom queries.

• Custom GraphQL queries
• Response validation
• Authentication headers

JSON API

json_api

Monitor REST APIs with JSON response validation.

• JSONPath validation
• Response value checks
• Schema validation

SSL Certificate

ssl_only

Monitor SSL certificate validity and expiration.

• Certificate expiry warnings
• Chain validation
• Hostname verification

Custom Script

script

Run custom scripts for specialized monitoring needs.

• Shell/Bash scripts
• Exit code validation
• Custom output parsing

Script Monitor Example

Custom scripts should exit with code 0 for success, non-zero for failure:

#!/bin/bash
# Example: Check disk space

THRESHOLD=90
USAGE=$(df -h / | awk 'NR==2 {print $5}' | tr -d '%')

if [ "$USAGE" -gt "$THRESHOLD" ]; then
  echo "Disk usage critical: $USAGE%"
  exit 1
fi

echo "Disk usage OK: $USAGE%"
exit 0

Best Practices

Use appropriate monitor types for each service (don't use HTTP for databases)
Set SSL expiry warnings at least 14 days before expiration
Keep custom scripts simple and fast-executing
Use service accounts with minimal permissions for cloud monitors
