Datadog has several default attributes that are appended to all log entries.
## `status`
The default `status` attribute is based off of the Syslog severity standards. You should use these values for any `status` attributes that you have to remap.
| Value | Description |
| --------|--------------|
| `emerg` | System is unusable |
| `alert` | Action must be taken immediately |
| `critical` | Critical condition |
| `error` | Error condition |
| `warning` | Potentially dangerous condition |
| `notice`| Normal but significant conditions |
|`info`| Informational messages confirming application is working.|
| `debug`| Messages useful when debugging an applicaiton.|
| `OK` | Success |
### Default mapping rules
Each incoming status value is mapped as follows:
- Integers from `0` to `7` map to the [Syslog severity standards](https://en.wikipedia.org/wiki/Syslog#Severity_level)
- Strings beginning with **`emerg`** or **f** (case-insensitive) map to **`emerg` (0)**
- Strings beginning with **`a`** (case-insensitive) map to **`alert` (1)**
- Strings beginning with **`c`** (case-insensitive) map to **`critical` (2)**
- Strings beginning with **`e`** (case-insensitive)—that do not match `emerg`—map to **`error` (3)**
- Strings beginning with **`w`** (case-insensitive) map to **`warning` (4)**
- Strings beginning with **`n`** (case-insensitive) map to **`notice` (5)**
- Strings beginning with **`i`** (case-insensitive) map to **`info` (6)**
- Strings beginning with **`d`**, **`trace`** or **`verbose`** (case-insensitive) map to **`debug` (7)**
- Strings beginning with **`o`** or **`s`**, or matching **`OK`** or **`Success`** (case-insensitive) map to **`OK`**
- All others map to **info (6)**
