canaryd is a simple HTTP monitoring tool that watches a configurable set of URLs and emits measurement data via UDP to a configurable set of targets.
It is the basic building block of canary.io.
$ go get github.com/canaryio/sensord $ cd $GOPATH/src/github.com/canaryio/sensord $ godep get $ godep go build
sensord is configured via the environment. The following values are allowed:
CHECKS_URL- location of checks data, defaults to https://s3.amazonaws.com/canary-public-data/checks.json
TARGETS- comma separated list of host:port pairs to send measurements to
LOCATION- name of this location, defaults to 'undefined'
MEASURER_COUNT- number of measurers to run. Defaults to '1'
CHECK_PERIOD- delay between checks, in ms. Defaults to '1000' (1 second)
sensord allows operational metrics to be sent to Librato. You can enable this by configured the following environment variables:
LIBRATO_EMAIL- email address of your librato account
LIBRATO_TOKEN- token for your Librato account
If you'd like to log metrics to
STDERR, you can do so by setting
LOGSTDERR to '1'.
