Error scraping for MariaDB metrics

Exporters and Metrics

Moin all.

We use bitnami/mysqld-exporter:0.12.1-debian-10-r10 to scrape our mariadb:10.5.8 container for metrics. Most metrics are successfully read, however a few seem to cause issues. We get the following errors in the logs for every scrape run:

time="2021-04-27T11:34:56Z" level=error msg="Error scraping for collect.info_schema.innodb_cmpmem: Error 1227: Access denied; you need (at least one of) the PROCESS privilege(s) for this operation" source="exporter.go:171" 
time="2021-04-27T11:34:56Z" level=error msg="Error scraping for collect.info_schema.innodb_cmp: Error 1227: Access denied; you need (at least one of) the PROCESS privilege(s) for this operation" source="exporter.go:171" 
time="2021-04-27T11:34:56Z" level=error msg="Error scraping for collect.slave_status: Error 1227: Access denied; you need (at least one of) the SUPER, REPLICATION SLAVE ADMIN privilege(s) for this operation" source="exporter.go:171"

There is nothing fancy about the MariaDB deployment, and the mysqld_exporter is configured as outlined in GitHub - prometheus/mysqld_exporter: Exporter for MySQL server metrics So we’re a bit puzzled why these errors show up.

Did anyone else run into this and solve it?

Thanks for any hints!

One possible answer might be that we don’t use those features, as we neither use compressed tables nor do we run a master-slave setup. But I’ll keep it open nonetheless.
