Project description

Graphite is a great tool for recording metrics but it isn’t easy to get paged when a metric passes a certain threshold.

Graphite-Pager is an easy to use alerting tool for Graphite that will send notification alerts if a metric reaches a warning or critical level.


  • Python 2.7+

  • Graphite

  • Redis

  • libmagic


Using PIP:

From Github:

pip install git+git://

From PyPI:

pip install graphitepager==0.2.11


At the moment the easiest way to install Graphite-Pager is with Heroku! See the example at

  1. Set Environment variables:

    export GRAPHITE_USER=HTTP-basic username
    export GRAPHITE_PASS=HTTP-basic password
    export GRAPHITE_URL=HTTPS(hopefully) URL to your Graphite installation
    export PAGERDUTY_KEY=Specific PagerDuty application key
    export REDIS_URL=redis://localhost:6379/
    # REDISTOGO_URL is also supported
  2. Set up alerts in the alerts.yml file

  3. Run graphite-pager:

    graphite-pager --config alerts.yml

Where the file alerts.yml is in the following format.

Environment variables can also be specified in the yaml file at the top level. Simply change the casing of the environment variable to lowercase like so:

redis_url: "redis://localhost:6379/"

Configuration of Alerts

Configuration of alerts is handled by a YAML file. This can be verified with

graphite-pager verfify --config=config.yml

If it’s invalid graphite-pager will likely crash.


Notifiers are what communicate with your preferred alerting service. Currently Graphite-Pager supports the following notifiers:

  • HipChat

  • PagerDuty

  • PushBullet

  • Slack

PagerDuty requires an application key set in the environment as PAGERDUTY_KEY

HipChat requires an application key HIPCHAT_KEY and the room to notify HIPCHAT_ROOM

Slack requires an slack SLACK_URL.

PushBullet requires an application key PUSHBULLET_KEY and optionally comma separated list of devices in PUSHBULLET_DEVICES and/or comma separated list of contacts in PUSHBULLET_CONTACTS.

More notifiers are easy to write, file an issue if there is something you would like!

Documentation url

An attribute of docs\_uls in the configuration will add a link to the documentation of the alert. Currently this is in the format of {docs\_url}/{alert name}#{alert legend name}

Alert Format

Alerts have 4 required arguments and 2 optional arguments.

Required arguments:

  • name - Name of thie alert group

  • warning - Int for a warning value

  • critical - Int for a critical value

  • target - Graphtie metric to check, best if aliased

Graphite Pager understands the values for warning and critical in order to check < and >. If warning is less than critical, values above either will trigger an alert. If warning is greater than critical than lower values will trigger the alert.


    Warning: 1
    Critical: 2

    0 is fine, 3 will be critical

    Warning: 2
    Critical: 1

    0 is critical, 3 is fine.

Optional argument:

  • from - The Graphite from parameter for how long to query for ex. -10min default -1min.

  • exclude - A list of targets to include. This must match the full target so it is recommended that you use the Graphite function alias() to make these readable.

Ordering of Alerts

Alerts with the same name and target will only be checked once! This is useful if you want to have a subset of metrics with different check times and/or values

- name: Load
  target: aliasByNode(servers.worker-*.loadavg01,1)
  warning: 10
  critical: 20

- name: Load
  target: aliasByNode(servers.*.loadavg01,1)
  warning: 5
  critical: 10

In the above example, any worker-* nodes will alert for anything 10 or higher but the catchall will allow for the remaining metrics to be checked without alerting for worker nodes above 5
