You have recently migrated vCenter Server running on Windows OS with Oracle Database to VCSALast Day/Week/Month/Year performance charts shows empty result while checking from UI or WebClient (Monitor -> Performance -> Overview or Advanced ->Select Last Day / Week / Month / Year)Historical stats in VCDB shows empty rows Connect to Postgres using command /opt/vmware/vpostgres/current/bin/psql -d VCDB -U postgres Execute below query select count( * ) from VPX_HIST_STAT2; Example: VCDB=# SELECT COUNT(*) FROM vpx_hist_stat2; count ------- 0 ---->>> shows 0 rows (1 row)
This is caused due to incorrect behavior of Stats Rollup Jobs on vCenter Server
Follow below steps to resolve the issue: Login to VCSA using SSH.Change shell to bash if you are on appliance shell. * List APIs: "help api list" * List Plugins: "help pi list" * Launch BASH: "shell"Command> shellShell access is granted to rootroot@vcsa1 [ ~ ]# Take backup of /usr/lib/vmware-vpx/sql/postgres.sql file before editing. cp /usr/lib/vmware-vpx/sql/postgres.sql /usr/lib/vmware-vpx/sql/postgres.sql_backup Stop VPXD Service. service-control --stop vmware-vpxd Note: vCenter Server will be down after stopping VPXD service, stop the service and proceed with the steps if you have downtime. Edit /usr/lib/vmware-vpx/sql/postgres.sql vi /usr/lib/vmware-vpx/sql/postgres.sql Search for strings "query:kQueryStatsStatIdNullDevice1Part" , "query:kQueryStatsStatIdNullDevice2", "query:kQueryStatsStatIdNullDevice3" and "query:kQueryStatsStatIdNullDevice4" in the postgres.sql file 7. Connect to Postgres using command: /opt/vmware/vpostgres/current/bin/psql -d VCDB -U postgres 8. Download the attached scripts and copy to VCSA (/tmp location) using WinScp, follow Error when uploading files to vCenter Server Appliance using WinSCP if you face difficulty to connect to VCSA. 9. Change ownership of copied files using below command: chown vpostgres:users /tmp/sql1 chown vpostgres:users /tmp/sql2 chown vpostgres:users /tmp/sql3 10. Recreate the Stats Rollup Procedures by importing the downloaded scripts. VCDB=# \i /tmp/sql2 VCDB=# \i /tmp/sql1 VCDB=# \i /tmp/sql3 Example: VCDB=# \i /tmp/SQL2 CREATE FUNCTION VCDB=# \i /tmp/SQL1 CREATE FUNCTION VCDB=# \i /tmp/SQL3 CREATE FUNCTION 11. Start VPXD service and refresh the UI Client. service-control --start vpxd Note: It will take some time to populate the historical data post recreating the jobs. You may verify the contents using Postgres query select count( * ) from VPX_HIST_STAT2; This will show the Stats available for Past Week data.
