One row per agent that failed at least once: how often the agent failed, for how many users, and with which result codes.
Errors: failures per agent, by result code, with the messages behind them
Error detail
Opening a row shows the agent's failures by version, then by result code, then by error message. Each message comes with the path of the command in the agent where the error occurred. The same message from two different paths is reported as two entries. Queries are not shown: a query is readable only by the person who typed it.
