Returns a function which accepts a single event or collection of events and sends them to KairosDB. Silently drops events when KairosDB is down. Attempts to reconnect automatically every five seconds. Use:

(kairosdb {:host "kairosdb.local" :port 4242 :protocol :tcp})

or

(kairosdb {:host "kairosdb.local" :port 8080 :protocol :http})

Options:

• :protocol :tcp to use the Telnet API, or :http for the HTTP REST API. Default :tcp.
• :metric-name A function which, given an event, returns the string describing the path of that event in kairosdb. kairosdb-metric-name by default.
• :tags A function which, given an event, returns the hash-map for the tags. kairosdb-tags by default.
• :pool-size The number of connections to keep open. Default 4.
• :reconnect-interval How many seconds to wait between attempts to connect. Default 5.
• :claim-timeout How many seconds to wait for a kairosdb connection from the pool. Default 0.1.
• :block-start Wait for the pool’s initial connections to open before returning.
• :ttl A function which, given an event, returns the TTL in seconds. Note: TTL is only supported in the HTTP API, and is ignored when sent via Telnet.

Constructs a metric-name for an event.

Constructs tags from an event. Fqdn in kairosdb is usually passed as a tag.
