# OpenTSDB TCP handler | |
# === | |
# | |
# This handler sends metrics to a OpenTSDB server via | |
# TCP socket. | |
# | |
# Compatible checks should generate output in the format: | |
# metric.path.one timestamp value host=fqdn\n | |
# metric.path.two timestamp value tag=mytag\n | |
# | |
# OpenTSDB 'server' and 'port' must be specified in a config file | |
# in /etc/sensu/conf.d. See opentsdb.json for an example. | |
