The NWUI console shows: Failed to fetch latest counts for Dashboard Error is fetching count of activities based on status from Monitoring Service The C:\Program Files\EMC NetWorker\nsr\authc-server\tomcat\logs\nwui.log shows: 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
The NWUI monitoring keystore certificate is not available in the NetWorker Runtime Environment (NRE) keystore. The NWUI monitoring needs permissions in the NRE keystore to authenticate to the NetWorker datazone. The cause of the missing NWUI monitoring process keystore certificate is not known. The NRE keystore should show the emcnwuimonitoring certificate details: 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>
The NWUI monitoring keystore certificate must be imported to the NRE keystore. Open a command prompt window with the "Run as administrator" option. Change to the NRE bin directory. The NRE path varies depending on the installed NRE version and server OS: Linux: cd /opt/nre/java/latest/bin/ Windows: cd "C:\Program Files\NRE\java\jre1.8.0_321\bin>" List the NRE keystore contents to validate the emcnwuimonitoring does not exist. Default password is " changeit ." Linux: ./keytool -list -keystore ../lib/security/cacerts | grep emcnwuimonitoring Windows: keytool.exe -list -keystore ..\lib\security\cacerts | findstr emcnwuimonitoring Import the NWUI monitoring keystore to the NRE keystore: 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 Stop the "NetWorker Backup and Recover Server" service: Linux: nsr_shutdown Windows: net stop nsrd Start the "NetWorker Backup and Recover Server" service: Linux: systemctl start networker Windows: net start nsrd List the NRE keystore contents to validate the emcnwuimonitoring exists with the default password of " changeit " . Linux: ./keytool -list -keystore ../lib/security/cacerts | grep emcnwuimonitoring Windows: keytool.exe -list -keystore ..\lib\security\cacerts | findstr emcnwuimonitoring Validate the symptom is no longer encountered in the NWUI.
