#### Logger as an `io.Writer`
Logrus can be transormed into an `io.Writer`. That writer is the end of an `io.Pipe` and it is your responsibility to close it.
```go
w := logger.Writer()
defer w.Close()
srv := http.Server{
// create a stdlib log.Logger that writes to
// logrus.Logger.

```
Each line written to that writer will be printed the usual way, using formatters
and hooks. The level for those entries is `info`.
#### Rotation
Log rotation is not provided with Logrus. Log rotation should be done by an
external program (like `logrotated(8)`) that can compress and delete old log
external program (like `logrotate(8)`) that can compress and delete old log
entries. It should not be a feature of the application-level logger.

# Sentry Hook for Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:" />
[Sentry](https://getsentry.com) provides both self-hosted and hosted
solutions for exception tracking.
Both client and server are
[open source](https://github.com/getsentry/sentry).
## Usage
Every sentry application defined on the server gets a different
[DSN](https://www.getsentry.com/docs/). In the example below replace
`YOUR_DSN` with the one created for your application.
```go
import (
"github.com/Sirupsen/logrus"
"github.com/Sirupsen/logrus/hooks/sentry"
)
func main() {
log := logrus.New()
hook, err := logrus_sentry.NewSentryHook(YOUR_DSN, []logrus.Level{
logrus.PanicLevel,
logrus.FatalLevel,
logrus.ErrorLevel,
})
if err == nil {
log.Hooks.Add(hook)
}
}
```
## Special fields
Some logrus fields have a special meaning in this hook,
these are server_name and logger.
When logs are sent to sentry these fields are treated differently.
- server_name (also known as hostname) is the name of the server which
is logging the event (hostname.example.com)
- logger is the part of the application which is logging the event.
In go this usually means setting it to the name of the package.
## Timeout
`Timeout` is the time the sentry hook will wait for a response
from the sentry server.
If this time elapses with no response from
the server an error will be returned.
If `Timeout` is set to 0 the SentryHook will not wait for a reply
and will assume a correct delivery.
The SentryHook has a default timeout of `100 milliseconds` when created
with a call to `NewSentryHook`. This can be changed by assigning a value to the `Timeout` field:
```go
hook, _ := logrus_sentry.NewSentryHook(...)
hook.Timeout = 20*time.Second
```
