configuration keys available
| `ozone.recon.db.dir` | | `OZONE`, `RECON`, `STORAGE`, `PERFORMANCE` |
Directory where the Recon Server stores its metadata. This should be specified
as a single directory. If the directory does not exist then the Recon will
attempt to create it. If undefined, then the Recon will log a warning and
fallback to `ozone.metadata.dirs`. This fallback approach is not recommended
for production environments. |
| `ozone.recon.db.dirs.permissions` | 700 | | Permissions for the metadata
directories for Recon. The permissions can either be octal or symbolic. If the
default permissions are not set then the default value of 700 will be used. |
| `ozone.recon.dn.metrics.collection.minimum.api.delay` | 30s | `OZONE`,
`RECON`, `DN` | Minimum delay in API to start a new task for Jmx collection. It
behaves like a rate limiter to avoid unnecessary task creation. |
+| `ozone.recon.dn.metrics.collection.thread.count` | 0 | `OZONE`, `RECON`,
`DN` | Size of the thread pool Recon uses to collect JMX metrics from
DataNodes. A value of 0 (or any non-positive value) means "auto" and selects 2
x Runtime.availableProcessors() at startup. |
| `ozone.recon.dn.metrics.collection.timeout` | 10m | `OZONE`, `RECON`, `DN` |
Maximum time taken for the api to complete. If it exceeds pending tasks will be
cancelled. |
| `ozone.recon.export.directory` | | `OZONE`, `RECON` | Directory where Recon
stores exported TAR files containing unhealthy container CSVs. When empty
(default), the path is resolved at runtime as `{ozone.recon.db.dir}`/exports so
exports are co-located with Recon metadata. |
| `ozone.recon.export.max.downloads` | 3 | `OZONE`, `RECON` | Maximum number
of times a completed export TAR file can be downloaded. Once the limit is
reached the download endpoint returns HTTP 429. Prevents repeated downloads
from misusing network bandwidth. |
