Instructions

如果 Isilon CEE 从 3 秒窗口之外的心跳请求获得响应，则将报告 STATUS_TIMEOUT 错误。  这是 Isilon 群集与 CEE 服务器之间的连接测试。  响应延迟可能是由许多可能的原因引起的，在这里我们将讨论我们看到的一些原因。
 
1.CEE 服务器驱动过度导致 CEE 服务器上的资源不足
  • 可能会导致处理响应延迟或过度驱动 CEE 服务器，使其无法在正确的时间内提供响应。 
2.DNS 查找时间太长
  •  导致完整的 TCP 数据包流持续时间过长
3.网络延迟

要查看 Overdriven CEE 服务器，我们可以查看该服务器上的任务管理器，并查看 CPU、内存和网络吞吐量的情况。  如果我们看到其中任何一项超过 90%，那么我们可能需要考虑添加更多 CEE 服务器以分散审核负载，或者增加允许 CEE 服务器使用的资源。  管理指南建议您保持 CEE 服务器与审核节点的 1：1 比例。

我们还希望使用以下两个命令查看当前积压的审核和当前导出率： 
# isi_for_array -sX 'isi_audit_progress -t protocol CEE_FWD'
# isi statistics query current --nodes=all --keys=node.audit.cee.export.rate

To avoid DNS lookup issues I advise to configure your CEE servers by IP instead of DNS name.  This eliminates DNS lookup and allows faster (marginally) audit performance with or without seeing the STATUS_TIMEOUT events.  


Network Delays can come up from many issues in the network configuration, a CEE server off site or on a different network with many hops can cause these requests to take longer than 3 seconds to complete.
