在 MetroCluster IP 交换机上配置日志收集

贡献者 netapp-aoife

在 MetroCluster IP 配置中，您可以配置日志收集以收集交换机日志以用于调试目的。

注意 在 Broadcom 和 Cisco 交换机上，每个具有日志收集功能的集群都需要一个新用户。例如，MetroCluster 1、MetroCluster 2、MetroCluster 3 和 MetroCluster 4 均需要在交换机上配置单独的用户。不支持为同一用户配置多个 SSH 密钥。
开始之前

  • 如果使用 FIPS 模式，请在设置日志收集之前完成以下操作：

    1. 按照供应商说明在交换机上重新生成SSH密钥。

    2. 使用 debug system regenerate-systemshell-key-pair 在 ONTAP 中重新生成 SSH 密钥。

    3. 使用 `system switch ethernet log setup-password`命令重新运行日志收集设置。

  • 您必须能够访问交换机 `show`命令。如果没有访问权限，请创建新的交换机用户并授予必要的权限。

  • 必须为交换机启用交换机运行状况监控。通过检查 `Is Monitored:`字段在 `system switch ethernet show`的输出中是否设置为 true 来验证。

  • 要使用Broadcom和Cisco交换机收集日志、请执行以下操作：

    • 本地用户必须具有网络管理员权限。

    • 为每个启用了日志收集的集群创建新的交换机用户。这些交换机不支持同一用户使用多个 SSH 密钥，再次运行设置将覆盖现有的 SSH 密钥。

  • 要使用 NVIDIA 交换机支持日志收集，日志收集用户必须能够在没有密码的情况下运行该 `cl-support`命令。要执行此操作，请运行：

    echo '<user> ALL = NOPASSWD: /usr/cumulus/bin/cl-support' | sudo EDITOR='tee -a' visudo -f /etc/sudoers.d/cumulus

步骤

按照适用于您的 ONTAP 版本的步骤设置日志收集，启用定期数据收集，并可选择请求按需支持日志。

ONTAP 9.15.1 及更高版本

  1. 要设置日志收集、请对每个交换机运行以下命令。系统会提示您输入交换机名称、用户名和密码以收集日志。

    注意：*如果对用户规范提示回答 *y，请确保用户具有必要的权限，如[开始之前] 。

    system switch ethernet log setup-password
    cluster1::*> system switch ethernet log setup-password
Enter the switch name: <return>
The switch name entered is not recognized.
Choose from the following list:
cs1
cs2

cluster1::*> system switch ethernet log setup-password

Enter the switch name: cs1
Would you like to specify a user other than admin for log collection? {y|n}: n

Enter the password: <enter switch password>
Enter the password again: <enter switch password>

cluster1::*> system switch ethernet log setup-password

Enter the switch name: cs2

Would you like to specify a user other than admin for log collection? {y|n}: n

Enter the password: <enter switch password>
Enter the password again: <enter switch password>
备注 对于 CL 5.11.1，创建用户 cumulus 并对以下提示回复 y：Would you like to specify a user other than admin for log collection? {y|n}: y

  1. 启用定期日志收集：

    system switch ethernet log modify -device <switch-name> -periodic-enabled true
    cluster1::*> system switch ethernet log modify -device cs1 -periodic-enabled true

Do you want to modify the cluster switch log collection configuration? {y|n}: [n] y

cs1: Periodic log collection has been scheduled to run every hour.

cluster1::*> system switch ethernet log modify -device cs2 -periodic-enabled true

Do you want to modify the cluster switch log collection configuration? {y|n}: [n] y

cs2: Periodic log collection has been scheduled to run every hour.

cluster1::*> system switch ethernet log show
                                          Periodic    Periodic    Support
Switch                                    Log Enabled Log State   Log State

cs1                                       true        scheduled   never-run
cs2                                       true        scheduled   never-run
2 entries were displayed.

  2. 请求支持日志收集：

    system switch ethernet log collect-support-log -device <switch-name>
    cluster1::*> system switch ethernet log collect-support-log -device cs1

cs1: Waiting for the next Ethernet switch polling cycle to begin support collection.

cluster1::*> system switch ethernet log collect-support-log -device cs2

cs2: Waiting for the next Ethernet switch polling cycle to begin support collection.

cluster1::*> *system switch ethernet log show
                                          Periodic    Periodic    Support
Switch                                    Log Enabled Log State   Log State

cs1                                       false       halted      initiated
cs2                                       true        scheduled   initiated
2 entries were displayed.

  3. 要查看日志收集的所有详细信息、包括启用、状态消息、定期收集的先前时间戳和文件名、请求状态、状态消息以及支持收集的先前时间戳和文件名、请使用以下命令：

    system switch ethernet log show -instance
    cluster1::*> system switch ethernet log show -instance

                    Switch Name: cs1
           Periodic Log Enabled: true
            Periodic Log Status: Periodic log collection has been scheduled to run every hour.
    Last Periodic Log Timestamp: 3/11/2024 11:02:59
          Periodic Log Filename: cluster1:/mroot/etc/log/shm-cluster-info.tgz
          Support Log Requested: false
             Support Log Status: Successfully gathered support logs - see filename for their location.
     Last Support Log Timestamp: 3/11/2024 11:14:20
           Support Log Filename: cluster1:/mroot/etc/log/shm-cluster-log.tgz

                    Switch Name: cs2
           Periodic Log Enabled: false
            Periodic Log Status: Periodic collection has been halted.
    Last Periodic Log Timestamp: 3/11/2024 11:05:18
          Periodic Log Filename: cluster1:/mroot/etc/log/shm-cluster-info.tgz
          Support Log Requested: false
             Support Log Status: Successfully gathered support logs - see filename for their location.
     Last Support Log Timestamp: 3/11/2024 11:18:54
           Support Log Filename: cluster1:/mroot/etc/log/shm-cluster-log.tgz
2 entries were displayed.
ONTAP 9.14.1及更早版本

  1. 要设置日志收集、请对每个交换机运行以下命令。系统会提示您输入交换机名称、用户名和密码以收集日志。

    *注：*如果回答 `y`用户规范提示，请确保用户具有中所述的必要权限[开始之前]。

    system switch ethernet log setup-password
    cluster1::*> system switch ethernet log setup-password
Enter the switch name: <return>
The switch name entered is not recognized.
Choose from the following list:
cs1
cs2

cluster1::*> system switch ethernet log setup-password

Enter the switch name: cs1
Would you like to specify a user other than admin for log collection? {y|n}: n

Enter the password: <enter switch password>
Enter the password again: <enter switch password>

cluster1::*> system switch ethernet log setup-password

Enter the switch name: cs2

Would you like to specify a user other than admin for log collection? {y|n}: n

Enter the password: <enter switch password>
Enter the password again: <enter switch password>
备注 对于 CL 5.11.1，创建用户 cumulus 并对以下提示回复 y：Would you like to specify a user other than admin for log collection? {y|n}: y

  1. 要请求支持日志收集并启用定期收集，请运行以下命令。此时将开始两种类型的日志收集：详细 Support 日志和每小时数据收集 Periodic 。

    system switch ethernet log modify -device <switch-name> -log-request true
    cluster1::*> system switch ethernet log modify -device cs1 -log-request true

Do you want to modify the cluster switch log collection configuration? {y|n}: [n] y

Enabling cluster switch log collection.

cluster1::*> system switch ethernet log modify -device cs2 -log-request true

Do you want to modify the cluster switch log collection configuration? {y|n}: [n] y

Enabling cluster switch log collection.

    等待10分钟、然后检查日志收集是否完成：

    system switch ethernet log show
注意 如果日志收集功能报告了任何错误状态(在的输出中可见 system switch ethernet log show)，请参见以了解更多详细信息。 "对日志收集进行故障排除"
