簡介

本檔案介紹有關備援Configuration Manager(RCM)日誌收集的一般程式。

RCM日誌收集過程

以下是RCM的元件：

• 控制器
• 檢查點管理器
• BFDMGR
• OPScenter
• Configmgr

根據問題場景，必須精確定位可作為捕獲日誌基礎的棘手元素。

所有元件的步驟都相同，如下所述。

• 如果您需要檢視最近的日誌，例如最近1到2小時內的日誌，您可以簡單地收集該特定元件的Pod日誌。
  
  

kubectl get svc  -o wide -A -n rcm

With this command, you get all the pods with their IPs and name.

kubectl logs <pod name> -n rcm

Just mention the pod name for which logs are required.

• 如果需要檢查超過2小時的日誌，RCM系統最多儲存所有生成的日誌4天。您可以按照此處列出的步驟檢索它們。

1.導航到目錄路徑： /var/log/containers 並使用  grep  命令，以搜尋所需的特定元件日誌。

In this scenario, let's take the controller as an example. If you require logs for configmgr/checkpointmgr, you need to use the 'grep' command, while the rest of the procedure remains unchanged.

root@h10-126-83-128:/var/log/containers# ls -la | grep controller 
lrwxrwxrwx  1 root root     107 Mar 29 07:07 rcm-controller-6547b466ff-zsrcd_rcm_rcm-controller-4c149c1e962992a241dd5201aadb07237f52947740724c1df2a01b1b6bfbc671.log -> /var/log/pods/rcm_rcm-controller-6547b466ff-zsrcd_ff74e5fc-9a07-4073-8956-90cd978ac98e/rcm-controller/0.log

2.查詢控制器目錄。

From Step 1., you can see the controller directory as mentioned here:

/var/log/pods/rcm_rcm-controller-6547b466ff-zsrcd_ff74e5fc-9a07-4073-8956-90cd978ac98e/rcm-controller/0.log

Get into this path

root@h10-126-83-128:/var/log/containers# ls -la /var/log/pods/rcm_rcm-controller-6547b466ff-zsrcd_ff74e5fc-9a07-4073-8956-90cd978ac98e/rcm-controller/

drwxr-xr-x 2 root root 4096 Mar 29 07:07 .
drwxr-xr-x 3 root root 4096 Mar 29 07:07 ..
lrwxrwxrwx 1 root root  165 Mar 29 07:07 0.log -> /var/lib/docker/containers/4c149c1e962992a241dd5201aadb07237f52947740724c1df2a01b1b6bfbc671/4c149c1e962992a241dd5201aadb07237f52947740724c1df2a01b1b6bfbc671-json.log

3.獲取所有 .log  檔案(tar/zipped)。

In Step 2, once you have obtained the path where log files are stored, navigate to that path and collect the .log/.gz files as needed.

root@h10-126-83-128:/var/log/containers# ls -la /var/lib/docker/containers/4c149c1e962992a241dd5201aadb07237f52947740724c1df2a01b1b6bfbc671/
