Symptoms

NWUI 控制台显示：

Failed to fetch latest counts for Dashboard
Error is fetching count of activities based on status from Monitoring Service


监视错误

而 C:\Program Files\EMC NetWorker\nsr\authc-server\tomcat\logs\nwui.log 显示：

HH:MM:SS [https-jsse-nio-9090-exec-2] ERROR c.e.n.c.n.i.MonitoringApi - Error in fetching count of activities based on status from Monitoring Service. javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path validation failed: java.security.cert.CertPathValidatorException: signature check failed

Cause

NetWorker Runtime Environment (NRE) 密钥库中不提供 NWUI 监视密钥库证书。NWUI 监视需要 NRE 密钥库中的权限才能向 NetWorker 数据区进行身份验证。NWUI 监视进程密钥库证书缺失的原因未知。


NRE 密钥库应显示 emcnwuimonitoring 证书详细信息：

C:\Program Files\NRE\java\jre1.8.0_321\bin>keytool.exe -list -keystore ..\lib\security\cacerts | findstr emcnwuimonitoring
Enter keystore password:  changeit
emcnwuimonitoring, Apr 27, 2022, trustedCertEntry,

C:\Program Files\NRE\java\jre1.8.0_321\bin>

Resolution

必须将 NWUI 监视密钥库证书导入 NRE 密钥库。 

  • 使用 “以管理员身份运行” 选项打开命令提示符窗口。
  • 更改为 NRE bin 目录。NRE 路径因安装的 NRE 版本和服务器作系统而异： 
Linux： 
cd /opt/nre/java/latest/bin/
Windows： 
cd "C:\Program Files\NRE\java\jre1.8.0_321\bin>"
  • 列出 NRE 密钥库内容以验证 emcnwuimonitoring 不存在。默认密码为 "changeit."
Linux：  
./keytool -list -keystore ../lib/security/cacerts | grep emcnwuimonitoring
Windows： 
keytool.exe -list -keystore ..\lib\security\cacerts | findstr emcnwuimonitoring
  • 将 NWUI 监视密钥库导入 NRE 密钥库：
Linux： 
./keytool -import -alias emcnwuimonitoring -file /nsr/nwui/monitoring/app/conf/emcnwuimonitoring.cer -keystore ../lib/security/cacerts
Windows： 
keytool.exe -importcert -alias emcnwuimonitoring -file "C:\Program Files\EMC NetWorker\nwui\monitoring\app\conf\emcnwuimonitoring.cer" -keystore ..\lib\security\cacerts
  • 停止 "NetWorker Backup and Recover Server" 服务：
Linux： 
nsr_shutdown
Windows： 
net stop nsrd
  • 启动 "NetWorker Backup and Recover Server" 服务：
Linux： 
systemctl start networker
Windows： 
net start nsrd
  • 列出 NRE 密钥库内容以验证 emcnwuimonitoring 存在，默认密码为 "changeit"。
Linux：  
./keytool -list -keystore ../lib/security/cacerts | grep emcnwuimonitoring
Windows： 
keytool.exe -list -keystore ..\lib\security\cacerts | findstr emcnwuimonitoring
  • 验证是否在 NWUI 中不再遇到症状。
