Investigate Data Collector Table Data Produced by a Scrutinize

The diagnostics tool scrutinize collects a broad range of information from a Vertica cluster. Part of the output from a scrutinize includes data collector table data. Once extracted, we can easily load the data from a data collector table file into a Vertica Flex Table for analysis!
Let’s take a look at the data from the DC_ERRORS data collector table stored in a file called Errors on node 2…
Example:
dbadmin=> CREATE FLEX TABLE scrut_errors();
CREATE TABLE
dbadmin=> \! pwd
/home/dbadmin/VerticaScrutinize.20190903125316/v_test_db_node0002/normal/DC
dbadmin=> COPY scrut_errors FROM '/home/dbadmin/VerticaScrutinize.20190903125316/v_test_db_node0002/normal/DC/Errors' PARSER fdelimitedparser(delimiter=E'\1', record_terminator=E'\2');
