QAN issues

This section focuses on problems with QAN, such as queries not being retrieved so on.

Missing data

Why don’t I see any query-related information?

There might be multiple places where the problem might come from:

  • Connection problem between pmm-agent and pmm-managed
  • PMM-agent cannot connect to the database.
  • Data source is not properly configured.

Why don’t I see the whole query?

Long query examples and fingerprints can be truncated to 1024 symbols to reduce space usage. In this case, the query explains section will not work.
