request system debug-info
语法
request system debug-info <node node-name>
语法（Junos EVO 设备）
request system debug-info <mode custom | lite | normal> <since duration> <node node-name>
描述
从 Junos OS 演化版收集调试信息，例如日志。日志存储在 / var/tmp/ 目录中。调试收集器收集核心、应用程序跟踪、配置、提交等。它还收集来自 CLI 和 CLI-PFE 命令的输出。您需要以 root 用户身份登录到设备才能使用此命令。输入 root 密码并在请求时进行确认。
选项
node node-name |
（可选）节点的标识符。如果给定了 （例如， ， ， |
mode |
|
since |
指定日志持续时间。支持的格式为 yyyy-mm-dd 或 #d（例如：2d）或 #h（例如：5h）。默认情况下，您可以收集持续时间为 90 天的日志。 |
其他信息
调试收集器在收集日志和跟踪时花费的时间最长。您可以使用命令从 request system debug-info / var/tmp 快速调试收集，示例格式如下：
-
request system debug-info node re0,fpc0,fpc1,fpc2 since 1h—正常模式，从主 RE 和所有 FPC 收集的日志和跟踪日志最少。 -
request system debug-info node re1 since 1h- 正常模式，仅从备份 RE 收集最少的日志和跟踪日志。 -
request system debug-info mode lite node re0,fpc0,fpc1,fpc2 since 1h— 精简模式，从主 RE 和所有 FPC 收集的日志和跟踪日志最少。 -
request system debug-info mode lite node re1 since 1h- 精简模式，仅从备份 RE 收集最少的日志和跟踪日志。
要查看 debug_collector.log 文件，请执行以下操作：
-
转到 / var/tmp/ 目录。
root@host:~# cd /var/tmp root@host:/var/tmp# ls debug_collector_2017-11-20_13_16_45.tar.gz
-
解压缩 / var/tmp/ 文件。
root@host:/var/tmp# tar -xf debug_collector_2017-11-20_13_16_45.tar.gz root@host:/var/tmp# ls debug_collector_2017-11-20_13_16_45 debug_collector_2017-11-20_13_16_45.tar.gz
-
转到 / var/tmp/debug_collector_timestamp 目录。
root@host:/var/tmp# cd debug_collector_2017-11-20_13_16_45 root@host:/var/tmp/debug_collector_2017-11-20_13_16_45# ls debug_collector.log re0 re1 fpc0
-
