Hi Brian, 

Thanks for your response. Can the below config be enough to send an alert when i create a file like ssl_expiry.rules?

groups: 
  - name: ssl_expiry.rules 
    rules: 
      - alert: SSLCertExpiringSoon 
        expr: probe_ssl_earliest_cert_expiry{job="blackbox"} - time() < 86400 * 30 
        for: 10m
