我做了什么？
通过我的 debian 8.x 主机上的命令行。
DD_API_KEY=[...] bash -c "$(curl -L https://raw.githubusercontent.com/DataDog/datadog-agent/master/cmd/agent/install_script.sh)"
预期行为：
● datadog-agent.service - "Datadog Agent"
Loaded: loaded (/lib/systemd/system/datadog-agent.service; enabled)
Active: active (running) since Tue 2018-04-24 10:42:36 CEST; 10h ago
实际行为：

问题：
由于结果状态：启动限制，我无法启动服务。我等了大约9个小时。我的想法是服务状态将从多次重启尝试中恢复。它没。有任何想法吗？
