grafana-alerts Collects stats from a grafana server based on information available
from the Grafana Dashboards. Then compare those values to an alert table and
throws alert emails if the case is needed.

Sites
Installation package: https://pypi.python.org/pypi/grafana_alerts
Project Home: https://github.com/pabloa/grafana-alerts
Issues and bugs: https://github.com/pabloa/grafana-alerts/issues

Installation
sudo pip install grafana-alerts
if you get an error, perhaps it is because the version available is a development
version. In this case try with:
sudo pip install --pre grafana-alerts

Configuration
Create a file /etc/grafana_alerts/grafana_alerts.cfg
with:
#
# Grafana alerts configuration file.
#

# The URL where grafana server is listening. It must finish with the character '/' (default value: http://localhost:3130)
grafana_url = http://yourgrafanaserver.com/grafana/

# Grafana token with viewer access (default value: empty string)
grafana_token = qwertysDssdsfsfsdfSFsfsfEWrwrwERwrewrwrWeRwRwerWRwERwerWRwerweRwrEWrWErwerWeRwRwrewerr==

# email to use as alert sender (default value: grafana-alert@localhost)
email_from = alert@example.com

# smtp server to use (default value: localhost)
smtp_server = localhost

# smtp server host to use (default value: 25)
# if port is not 25, starts a tls session.
smtp_port = 25

# smtp server username to use if it is needed. Optional. Leave it commented if not used. (default value: no username)
#smtp_username = my_smtp_username

# smtp server password to use if it is needed. Optional. Leave it commented if not used. (default value: no password)
#smtp_password = my_smtp_password
Add a cron task to execute grafana_alerts for example each 3 minutes::
*/3 * * * * grafana_alerts

Monitoring Dashboards
Dashboards to be monitored for alerts must be marked with the tag “monitored”
In each monitored Dashboard, add a text panel with title ‘alerts’ and a description of your alerts. For example::
50<=x<=100; normal; server@example.com

35<x<50; warning; server-mantainers@example.com

x<=35; critical; server-mantainers@example.com, sysop@example.com
Notes:

values depend of the graph in that dashboard.
x is mandatory.
