LIST 10 LARGEST TABLES (vPostgres)

Posted by

Connecting to a vPostgres instance:

For most VMware products you can connect to the vPostgres instance using the command below

/opt/vmware/vpostgres/current/bin/psql -U postgres -d VCDB

Sometimes, the default user for vPostgres is not “postgres”. The above command will fail in that case. One such application is Site Recovery Manager. For these applications, you can find the vPostgres user details by reviewing the out of ps -aux command.

Look at the line 3, the location following “-D” is where you should find pg_hba.conf. Look at the line 11 and 22, the information following “postgres:” is “user” followed by “database”

ps -aux | grep -i postgres

To connect to a vPostgres instance using an application specific user like “vc” or “vumuser” you can use following commands. The command requires “vc” or “vumuser” password when prompted.

/opt/vmware/vpostgres/current/bin/psql -U vc -d VCDB
Password for user vc:
/opt/vmware/vpostgres/current/bin/psql -U vumuser -d VCDB
Password for user vumuser:

The password for “vc” and “vumuser” can be found in their respective database configuration file. These files can also be used to find application specific users.

cat /etc/vmware-vpx/vcdb.properties
driver = org.postgresql.Driver
dbtype = PostgreSQL
url = jdbc:postgresql://localhost:5432/VCDB
username = vc
password = fJ{>5cD^h9*WuIUq

Listing 10 largest tables (vc):

After connection to vPostgres instance on vCenter server execute the following code. Just copy and past

SELECT schema_name, relname, pg_size_pretty(table_size) AS size, table_size FROM ( SELECT pg_catalog.pg_namespace.nspname  AS schema_name, relname, pg_relation_size(pg_catalog.pg_class.oid) AS table_size  FROM pg_catalog.pg_class JOIN pg_catalog.pg_namespace ON relnamespace = pg_catalog.pg_namespace.oid) t WHERE schema_name NOT LIKE 'pg_%' and schema_name like 'vc' ORDER BY table_size DESC limit 10;
