Monitoring: queries-failed
The queries-failed variable counts how many database queries have failed since the server started.
There are only a few conditions that can make this be non-zero:
- Postgres restarting while Archiveopteryx is running. This is usually handled gracefully.
- Race conditions while inserting into e.g. the addresses or field_names tables. These races are handled using SQL savepoints.
- Bugs in Archiveopteryx.
In case of questions, please write to info@aox.org.
