Symptoms
NWUI 主控台顯示:
Failed to fetch latest counts for Dashboard
Error is fetching count of activities based on status from Monitoring Service

可使用 C:\Program Files\EMC NetWorker\nsr\authc-server\tomcat\logs\nwui.log 顯示:
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 failedCause
NetWorker Runtime Environment (NRE) 金鑰存放區中無法取得 NWUI 監控金鑰存放區憑證。NWUI 監控需要 NRE 金鑰存放區中的權限,才能對 NetWorker 資料區進行驗證。不知道 NWUI 監控程序金鑰存放區憑證遺失的原因。
NRE 金鑰存放區應顯示 emcnwuimonitoring 憑證詳細資料:
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
NWUI 監控金鑰存放區憑證必須匯入到 NRE 金鑰存放區。
- 使用 「以系統管理員身分執行」 選項開啟命令提示字元視窗。
- 變更為 NRE bin 目錄。NRE 路徑會因安裝的 NRE 版本和伺服器作業系統而有所不同:
Linux:
cd /opt/nre/java/latest/bin/
Windows:
cd "C:\Program Files\NRE\java\jre1.8.0_321\bin>"
- 列出 NRE 金鑰存放區內容以驗證
emcnwuimonitoring不存在。預設密碼為"changeit."
Linux:
./keytool -list -keystore ../lib/security/cacerts | grep emcnwuimonitoring
Windows:
keytool.exe -list -keystore ..\lib\security\cacerts | findstr emcnwuimonitoring
- 將 NWUI 監控金鑰存放區匯入 NRE 金鑰存放區:
Linux:
./keytool -import -alias emcnwuimonitoring -file /nsr/nwui/monitoring/app/conf/emcnwuimonitoring.cer -keystore ../lib/security/cacertsWindows:
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"服務:
Linux:
nsr_shutdown
Windows:
net stop nsrd
- 啟動
"NetWorker Backup and Recover Server"服務:
Linux:
systemctl start networkerWindows:
net start nsrd
- 列出 NRE 金鑰存放區內容以驗證
emcnwuimonitoring存在,預設密碼為"changeit"。
Linux:
./keytool -list -keystore ../lib/security/cacerts | grep emcnwuimonitoring
Windows:
keytool.exe -list -keystore ..\lib\security\cacerts | findstr emcnwuimonitoring
- 驗證 NWUI 中不再發生症狀。
