Pivotal Greenplum Command Center (GPCC) 3.x
Dashboard and Cluster Metrics views show no data in the histogram charts.
This issue is caused when the default timezone has changed for the gpmon user and the gpperfmon database. Pivotal Greenplum Command Center (GPCC) requires that the gpmon user and the gpperfmon database use the same default timezone as that of the system they are operating on.
Run the following query to fix this issue:
alter user gpmon reset timezone;
alter database gpperfmon reset timezone; restart gpcc
