我使用用户名/密码和ssh密钥对在jenkins上创建了一个从节点，当我从节点打开ssh连接时，堆栈跟踪中出现错误“错误：无法监视可用交换空间”

[05/10/24 16:55:47] [SSH] SSH host key matches key seen previously for this host. Connection will be allowed.
首先，经常会看到“可用交换空间错误”，其次它是否实际连接，因为最后它说“[SSH] SSH 主机密钥与该主机之前看到的密钥匹配。将允许连接。”
是的，节点连接成功。节点监控不起作用，因为您的节点正在运行 Jenkins 不知道如何监控的操作系统版本。这显然不理想，但不会造成任何问题。
