]}
```

Requirements
------------

- python (2.7, 3.3, 3.4)
- tornado

Installation
------------

### Python package

**Graphite-beacon** could be installed using pip:

pip intall graphite-beacon

### Debian package

echo "deb http://dl.bintray.com/klen/deb /" | sudo tee -a /etc/apt/sources.list
echo "deb-src http://dl.bintray.com/klen/deb /" | sudo tee -a /etc/apt/sources.list

Install the package using apt-get:

apt-get update
apt-get install graphite-beacon

### Ansible role

There is an ansible role to install the package: https://github.com/Stouts/Stouts.graphite-beacon

Usage
-----

Just run `graphite-beacon`:

$ graphite-beacon
[I 141025 11:16:23 core:141] Read configuration
[I 141025 11:16:23 core:55] Memory (10minute): init
[I 141025 11:16:23 core:166] Loaded with options:
...

### Configuration

___

> Time units: '2second', '3.5minute', '4hour', '5.2day', '6week', '7month', '8year'
> short formats are: '2s', '3m', '4.1h' ...

> Value units:
> short: '2K', '3Mil', '4Bil', '5Tri'
> bytes: '2KB', '3MB', '4GB'
> time: '2s', '3m', '4h', '5d'

**Graphite-beacon** default options are:

> Comment lines are not allowed in JSON, but Graphite-beacon strips them

```js

{
// Path to a configuration
"config": "config.json",

// Graphite server URL
"graphite_url": "http://localhost",

// HTTP AUTH username
"auth_usernamename": null,

// HTTP AUTH password
"auth_password": null,

// Path to a pidfile
"pidfile": null,

// Default values format (none, bytes, s, ms, short)
// Can be redfined for each alert.
"format": "short",

// Default query interval
// Can be redfined for each alert.
"interval": "10minute",

// Notification repeat interval
// If an alert is failed, its notification will be repeated with the interval below
"repeat_interval": "2hour",

// Default loglevel
"logging": "info",

// Default method (average, last_value).
// Can be redfined for each alert.
"method": "average",

// Default prefix (used for notifications)
"prefix": "[BEACON]",

// Default handlers (log, smtp, hipchat)
"critical_handlers": ["log", "smtp"],
"warning_handlers": ["log", "smtp"],
"normal_handlers": ["log", "smtp"],

// Default alerts (see configuration below)
"alerts": []
}
```

You can setup options with a configuration file. See
`example-config.json`.

#### Include

You can include any configuration files:
```js
...
"include": [ "path/to/config1.json", "path/to/config2.json"]
```

#### Setup alerts

At the moment **Graphite-beacon** supports two type of alerts:
- Graphite alert (default) - check graphite metrics
- URL alert (default) - load http and check status

> Comment lines are not allowed in JSON, but Graphite-beacon strips them

```js

"alerts": [
{
// (required) Alert name
"name": "Memory",

// (required) Alert query
"query": "*.memory.memory-free",

//(optional) Alert type (graphite, url)
"source": "graphite",

//(optional) Default values format (none, bytes, s, ms, short)
"format": "bytes",

// (optional) Alert method (average, last_value)
"method": "average",

// (optional) Alert interval [eg. 15second, 30minute, 2hour, 1day, 3month, 1year]
"interval": "1minute",

// (required) Alert rules
// Rule format: "{level}: {operator} {value}"
// Level one of [critical, warning, normal]
// Operator one of [>, <, >=, <=, ==, !=]
// Value (absolute value: 3000000 or short form like 3MB/12minute)
"rules": [ "critical: < 200MB", "warning: < 300MB" ]
}
]
```

### Setup SMTP

Enable "smtp" handler (enabled by default) and set the options in your beacon
configuration.

```js
{
...
// Set from email
"smtp_from": "beacon@graphite",

// Set "to" email
"smtp_to": []

// Set SMTP host
"smtp_host": "localhost",

// Set SMTP port
"smtp_port": 25,

// Set SMTP user
"smtp_username": null,

// Set SMTP password
"smtp_password": null,

// Use TLS
"smtp_use_tls": false,

...
}
```

### Setup HipChat

Enable "hipchat" handler and set the options in your beacon configuration.

```js
{
...
"hipchat_room": "myroom",
"hipchat_key": "mykey",
...
}
```

### Command line

```
$ graphite-beacon --help
Usage: graphite-beacon [OPTIONS]

Options:

--config Path to an configuration file (YAML)
(default config.json)
--graphite_url Graphite URL (default http://localhost)
--help show this help information
--pidfile Set pid file

--log_file_max_size max size of log files before rollover
(default 100000000)
--log_file_num_backups number of log files to keep (default 10)
--log_file_prefix=PATH Path prefix for log files. Note that if you
are running multiple tornado processes,
log_file_prefix must be different for each
of them (e.g. include the port number)
--log_to_stderr Send log output to stderr (colorized if
possible). By default use stderr if
--log_file_prefix is not set and no other
logging is configured.
--logging=debug|info|warning|error|none
Set the Python log level. If 'none', tornado
won't touch the logging configuration.
(default info)
```
