- **iotime** - Time spent on IO in milliseconds.
- **queue** - Lenght of IO queue.
## Filesystem Extension
### Metrics
-
- **free_bytes** - Free bytes for filesystem.
- **total_bytes** - Total bytes for filesystem.
- **free_inoed** - Free inodes for filesystem.
- **total_inodes** - Total inodes for filesystem.
### Configuration
```toml
[extension.base_filesystem]
enabled = true
exclude_type = [ "tmpfs", "ahafs" ]
exclude_mount = [ "/boot/efi" ]
```
## Process Extension
Reports metrics on one or more running processes.
