graphite-beacon
Simple alerting system for Graphite metrics.
Features:
- Simple installation
- No software dependencies (Databases, AMQP and etc)
- Light and fully asynchronous
- SMTP, HipChat, Slack, PagerDuty, HTTP handlers (PRs for additional handlers are welcome!)
- Easily configurable and supports historical values
Example:
{
"graphite_url": "http://g.server.org",
"smtp": {
"from": "[email protected]",
"to": ["[email protected]"]
},
"alerts": [
{ "name": "MEM",
"format": "bytes",
"query": "aliasByNode(sumSeriesWithWildcards(collectd.*.memory.{memory-free,memory-cached}, 3), 1)",
"rules": ["critical: < 200MB", "warning: < 400MB", "warning: < historical / 2"] },
{ "name": "CPU",
"format": "percent",
"query": "aliasByNode(sumSeriesWithWildcards(collectd.*.cpu-*.cpu-user, 2), 1)",
"rules": ["critical: >= 80%", "warning: >= 70%"] }
]}

There is an ansible role to install the package: https://github.com/Stouts/Stouts.graphite-beacon
Docker
Build a config.json file and run :
docker run -v /path/to/config.json:/srv/alerting/etc/config.json deliverous/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

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'

The default options are:
Note: comments are not allowed in JSON, but graphite-beacon strips them
{
// Graphite server URL
"graphite_url": "http://localhost",
// Public graphite server URL
// Used when notifying handlers, defaults to graphite_url
"public_graphite_url": null,
// HTTP AUTH username
"auth_username": null,
// HTTP AUTH password
"auth_password": null,
// Path to a pidfile
"pidfile": null,
// Default values format (none, bytes, s, ms, short)
// Can be redefined for each alert.
"format": "short",
// Default query interval
// Can be redefined for each alert.
"interval": "10minute",
// Default time window for Graphite queries
// Defaults to query interval, can be redefined for each alert.
"time_window": "10minute",
// Notification repeat interval
// If an alert is failed, its notification will be repeated with the interval below
"repeat_interval": "2hour",
// Default end time for Graphite queries
// Defaults to the current time, can be redefined for each alert.
"until": "0second",
// Default loglevel
"logging": "info",
// Default method (average, last_value, sum, minimum, maximum).
// Can be redefined for each alert.
"method": "average",
// Default alert to send when no data received (normal = no alert)
// Can be redefined for each alert
"no_data": "critical",

// (normal = no alert)
// Can be redefined for each alert
"loading_error": "critical"
// Default prefix (used for notifications)
"prefix": "[BEACON]",
// Default handlers (log, smtp, hipchat, http, slack, pagerduty)
"critical_handlers": ["log", "smtp"],
"warning_handlers": ["log", "smtp"],
"normal_handlers": ["log", "smtp"],
// Send initial values (Send current values when reactor starts)
"send_initial": true,
// used together to ignore the missing value
"default_nan_value": -1,
"ignore_nan": false,
// Default alerts (see configuration below)
"alerts": [],
// Path to other configuration files to include
"include": []
}
You can setup options with a configuration file. See examples for JSON and YAML.
A config.json
file in the same directory that you run graphite-beacon
from will be used automatically.
Setup alerts
Currently two types of alerts are supported:
- Graphite alert (default) - check graphite metrics
- URL alert - load http and check status
Note: comments are not allowed in JSON, but graphite-beacon strips them
"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, minimum, maximum)
"method": "average",
// (optional) Alert interval [eg. 15second, 30minute, 2hour, 1day, 3month, 1year]
"interval": "1minute",
// (optional) What kind of alert to send when no data received (normal = no alert)
"no_data": "warning",
// (optional) Alert interval end time (see "Alert interval" for examples)
"until": "5second",
// (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)
// Multiple conditions can be separated by AND or OR conditions
"rules": [ "critical: < 200MB", "warning: < 300MB" ]
}
]
Historical values
graphite-beacon supports "historical" values for a rule. For example you may want to get warning when CPU usage is greater than 150% of normal usage:
"warning: > historical * 1.5"
Or memory is less than half the usual value:
"warning: < historical / 2"
Historical values for each query are kept. A historical value
represents the average of all values in history. Rules using a historical value will
only work after enough values have been collected (see history_size
).
History values are kept for 1 day by default. You can change this with the history_size
option.
See the below example for how to send a warning when today's new user count is less than 80% of the last 10 day average:
alerts: [
{
"name": "Registrations",
// Run once per day
"interval": "1day",
"query": "Your graphite query here",
// Get average for last 10 days
"history_size": "10day",
"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"
]
}
],
Handlers
Handlers allow for notifying an external service or process of an alert firing.
Email Handler
Sends an email (enabled by default).
{
// SMTP default options
"smtp": {
"from": "beacon@graphite",
"to": [], // List of email addresses to send to
"host": "localhost", // SMTP host
"port": 25, // SMTP port
"username": null, // SMTP user (optional)
"password": null, // SMTP password (optional)
"use_tls": false, // Use TLS?
"html": true, // Send HTML emails?
// Graphite link for emails (By default is equal to main graphite_url)
"graphite_url": null
}
}
HipChat Handler
Sends a message to a HipChat room.
{
"hipchat": {
// (optional) Custom HipChat URL
"url": 'https://api.custom.hipchat.my',
"room": "myroom",
"key": "mykey"
}
}
Webhook Handler (HTTP)
Triggers a webhook.
{
"http": {
"url": "http://myhook.com",
"params": {}, // (optional) Additional query(data) params
"method": "GET" // (optional) HTTP method
}
}
Slack Handler
Sends a message to a user or channel on Slack.
{
"slack": {
"webhook": "https://hooks.slack.com/services/...",
"channel": "#general", // #channel or @user (optional)
"username": "graphite-beacon",
}
}
Command Line Handler
Runs a command.
{
"cli": {
// Command to run (required)
// Several variables that will be substituted by values are allowed:
// ${level} -- alert level
// ${name} -- alert name
// ${value} -- current metrics value
// ${limit_value} -- metrics limit value
"command": "./myscript ${level} ${name} ${value} ...",
// Whitelist of alerts that will trigger this handler (optional)
// All alerts will trigger this handler if absent.
"alerts_whitelist": ["..."]
}
}
PagerDuty Handler
Triggers a PagerDuty incident.
{
"pagerduty": {
"subdomain": "yoursubdomain",
"apitoken": "apitoken",
"service_key": "servicekey",
}
}
Telegram Handler
Sends a Telegram message.
{
"telegram": {
"token": "telegram bot token",
"bot_ident": "token you choose to activate bot in a group"
"chatfile": "path to file where chat ids are saved, optional field"
}
}
Command Line Usage
$ graphite-beacon --help
Usage: graphite-beacon [OPTIONS]
Options:
--config Path to an configuration file (JSON/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.
