# Papertrail Hook for Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:" />
[Papertrail](https://papertrailapp.com) provides hosted log management. Once stored in Papertrail, you can [group](http://help.papertrailapp.com/kb/how-it-works/groups/) your logs on various dimensions, [search](http://help.papertrailapp.com/kb/how-it-works/search-syntax) them, and trigger [alerts](http://help.papertrailapp.com/kb/how-it-works/alerts).
In most deployments, you'll want to send logs to Papertrail via their [remote_syslog](http://help.papertrailapp.com/kb/configuration/configuring-centralized-logging-from-text-log-files-in-unix/) daemon, which requires no application-specific configuration. This hook is intended for relatively low-volume logging, likely in managed cloud hosting deployments where installing `remote_syslog` is not possible.
## Usage
You can find your Papertrail UDP port on your [Papertrail account page](https://papertrailapp.com/account/destinations). Substitute it below for `YOUR_PAPERTRAIL_UDP_PORT`.
For `YOUR_APP_NAME`, substitute a short string that will readily identify your application or service in the logs.
```go
import (
"log/syslog"
"github.com/Sirupsen/logrus"
"github.com/Sirupsen/logrus/hooks/papertrail"
)
func main() {
log := logrus.New()
hook, err := logrus_papertrail.NewPapertrailHook("logs.papertrailapp.com", YOUR_PAPERTRAIL_UDP_PORT, YOUR_APP_NAME)
if err == nil {
log.Hooks.Add(hook)
}
}

# 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)
}
}
```
If you wish to initialize a SentryHook with tags, you can use the `NewWithTagsSentryHook` constructor to provide default tags:
```go
tags := map[string]string{
"site": "example.com",
}
levels := []logrus.Level{
logrus.PanicLevel,
logrus.FatalLevel,
logrus.ErrorLevel,
}
hook, err := logrus_sentry.NewWithTagsSentryHook(YOUR_DSN, tags, levels)
```
If you wish to initialize a SentryHook with an already initialized raven client, you can use
the `NewWithClientSentryHook` constructor:
```go
import (
"github.com/Sirupsen/logrus"
"github.com/Sirupsen/logrus/hooks/sentry"
"github.com/getsentry/raven-go"
)
func main() {
log := logrus.New()
client, err := raven.New(YOUR_DSN)
if err != nil {
log.Fatal(err)
}
hook, err := logrus_sentry.NewWithClientSentryHook(client, []logrus.Level{
logrus.PanicLevel,
logrus.FatalLevel,
logrus.ErrorLevel,
})
if err == nil {
log.Hooks.Add(hook)
}
}
hook, err := NewWithClientSentryHook(client, []logrus.Level{
logrus.ErrorLevel,
})
```
## Special fields
Some logrus fields have a special meaning in this hook,
these are `server_name`, `logger` and `http_request`.
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.
- `http_request` is the in-coming request(*http.Request). The detailed request data are sent to Sentry.
## 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
```
