The LICENSE_AUDITS system table lists the results of Vertica’s license automatic compliance audits. You can query it to track your Vertica license usage over time!

Example: dbadmin=> SELECT * FROM ( dbadmin(> SELECT TRUNC(audit_start_timestamp)::DATE the_date, usage_percent * 100 AS usage_percent dbadmin(> FROM license_audits dbadmin(> WHERE audited_data = 'Total' dbadmin(> LIMIT 1 OVER (PARTITION BY TRUNC(audit_start_timestamp) ORDER BY audit_start_timestamp DESC) dbadmin(> ) foo dbadmin-> ORDER BY 1 DESC dbadmin-> LIMIT 7; the_date | usage_percent ------------+---------------------- 2019-06-26 | 85.04858490293070432 2019-06-25 | 85.94124716031121234 2019-06-24 | 84.73165229437051977 2019-06-23 | 82.52812722831650034 2019-06-22 | 81.48804673106092692 2019-06-21 | 83.15786945786393982 2019-06-20 | 83.07077737097440010 (7 rows) Looks like I’m going to need add some new Vertica license soon!
