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'

> bits: '2Kb', '3Mb', '4Gb'

> bps: '2Kbps', '3Mbps', '4Gbps'

> 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, sum).
// Can be redfined for each alert.
"method": "average",

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

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

// Send initial values (Send current values when reactor starts)
"send_initial": true,

// 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, sum)
"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" ]
}
]
```

##### Historical values

Graphite-beacon supports "historical" values for a rule.
By example, you want to get warning when CPU usage is more than 150% from normal usage:

"warning: > historical * 1.5"

Or memory is twice less than usual:

"warning: < historical / 2"


Graphite-beacon keeps history of values for each target in metric. Historical value
is average of values from history. "Historical" rule becames work when it has enough
values (Read about history size bellow).

History size is equal 60 by default. You can change it by using Reactor option
'history_size'.

By example, send warning when today' new user is less than 80% of average for last 10 days:

```js
...
alerts: [
...
{
"name": "Registrations",
// Run once per day
"interval": "1day",
"query": "Your graphite query here",
// Get average for last 10 days
"history_size": 10,
"rules": [
// Warning if today's new user less than 80% of average for 10 days
"warning: < historical * 0.8",
// Critical if today's new user less than 50% of average for 10 days
"critical: < historical * 0.5"
]
}
...
],
...
```

### Setup SMTP

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

```js
{
...
// SMTP default options
"smtp": {

// Set from email
"from": "beacon@graphite",

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

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

// Set SMTP port
"port": 25,

// Set SMTP user
"username": null,

// Set SMTP password
"password": null,

// Use TLS
"use_tls": false,

// Send HTML emails
"html": true,

// Graphite link for emails (By default is equal to main graphite_url)
"graphite_url": null

}

...
}
```

### Setup HipChat

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

```js
{
...
"hipchat": {
"room": "myroom",
"key": "mykey"
}
...
}
```

### Setup HttpHandler

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

```js
{
...
"http": {
"url": "http://myhook.com",

// (optional) Additional query(data) params
"params": {},

// (optional) HTTP method
"method": "GET"

}
...
}
```

### 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)
