RCMノードの状態の確認

概要

このドキュメントでは、Redundancy Configuration Manager(RCM)ヘルスチェックの一般的な手順について説明します。

手順

RCMで言及されているコンポーネントは次のとおりです。

• Controller
• Checkpointmgr
• Bfdmgr
• OPScenter
• Configmgr

rcm show-statistics bfdmgr           

------------------------- to check bfdmgr status

rcm show-statistics configmgr    

-------------------------  to check how many UPs are registered for config push

rcm show-statistics checkpointmgr

------------------------ to check how many UPs are registered for checkpoint sync with their no of instances

rcm show-statistics checkpointmgr-endpoint upfAddr ipv4_address

------------------------ to check how checkpoint status for one particular UP

rcm show-statistics checkpointmgr-endpointstats

------------------------ to check how checkpoint status for overall all the UPs registered with their instance

rcm show-statistics checkpointmgr-session upfAddr ipv4_address

---------------------- to check statistics of checkpoint sync per UP based on its IP address

rcm show-statistics controller

--------------------- to check no of UPs and its states registered with controller

rcm show-statistics switchover

rcm show-statistics switchover-verbose

--------------------- above 2 command to check the UP switchover details



rcm support-summary  --------- whole RCM components details would be captured

show running-config      --------- To get whole config present in opscenter

注:RCMのOpscenterからこれらすべてのコマンドを実行します。

Opscenterにアクセスするプロセスを次に示します。

kubectl get svc  -o wide -A

By this command you will get all the pods with their IPs and name

ssh -p 2024 admin@<ops-center pod IP>

Here port is 2024 and user is admin for opscenter and IP we can get from svc command

cat /etc/smi/rcm-image-version

To check RCM version which can be directly executed on RCM but verify the file name : “rcm-image-version” once in the same path as file name can be different for different customers

systemctl status kubelet                    -------------- kubelet statistics

systemctl status host_reboot.service        ------------- to check status of Active RCM

kubectl get pods -A                         ------------- list of pods created in the node

kubectl describe pod <pod name> -n rcm      ------------- shows details of each container in this pod

kubectl get svc  -n rcm                     ------------- To get service IP and port of container

ssh -p 2024 admin@<pod IP>                  ------------ Get into that Pod

kubectl get cm –n rcm                       ------------ To check different config maps

kubectl logs <pod name> -n rcm              ------------- to check pod level logs
