CL-INFLUXDB
-------------

This package is a native Common Lisp interface for the InfluxDB time series database.

[InfluxDB](http://influxdb.org) is a scalable time series database.

News
----
CL-INFLUXDB has been upgraded to support influxdb version 1

The interface `cl-influxdb` that works with version 0.8 and below has been changed to `cl-influxdb-v8` specific information regarding the v8 interface can be obtained by reading README-v8.md.The interface that works with 0.9 is now `cl-influxdb`.
    
One of the major changes starting in version 0.9 and above is that much functionality including most administrative functions have been pulled into the InfluxDB query language. Therefor many of the administrative interface functions have been removed from this interface.

Installation
------------
cl-influxdb is distributed via [Quicklisp](http://quicklisp.org).
It can also be obtained via it's [github repository] (http://github.com/mmaul/cl-influxdb)

Usage
------
For query and administrative commands see the [InfluxDB Documentation](https://influxdb.com/docs/v0.9/). All administrative commands are issued via the `query` method.

Load library and create a instance of class INFLUXDB, using the default is
user = root, password = root, host = 127.0.0.1, port = 8086.



    (ql:quickload :cl-influxdb)       

    To load "cl-influxdb":
      Load 1 ASDF system:
        cl-influxdb
    
    ; Loading "cl-influxdb"
    ..........
    (:CL-INFLUXDB)

    (defpackage #:cl-influxdb-example
      (:use #:cl #:cl-influxdb
            ))

    #<PACKAGE "CL-INFLUXDB-EXAMPLE">

    (in-package :cl-influxdb-example)

    #<PACKAGE "CL-INFLUXDB-EXAMPLE">



Lets create a instance of class INFLUXDB to get started the default is
user = root, password = root, host = 127.0.0.1, port = 8086.


    (defparameter influxdb  (make-instance 'influxdb :database "cl_influxdb_example" :user "root" :password "root"))    

    INFLUXDB



Create a database, or if the database already exists handle the `command-fail` condition.


    (handler-case (create-database influxdb "cl_influxdb_example" ) (command-fail (e) e))

    T



Data is writtent by populating a influxdb-data structure and writing it to the database


    (write-points influxdb 
        (make-influxdb-data :key :response_times :tags '((:host . "server1") (:region . "one")) 
            :columns '(:t1 :v1 :c1) 
            :points '((1394761721 "Y" 1.0 1442377210) 
                      (1394761722 "X" 2.0 1442377211)))
                      :time-precision :s)

    T

    (query influxdb "select time,v1,c1,t1 from response_times;")

    ((:RESULTS
      ((:SERIES
        ((:NAME . "response_times") (:COLUMNS "time" "v1" "c1" "t1")
         (:VALUES ("2015-09-16T04:20:10Z" "Y" 1 1394761721)
          ("2015-09-16T04:20:11Z" "X" 2 1394761722)))))))



Now clean up and drop the database


    (query influxdb "drop database cl_influxdb_example")

    ((:RESULTS NIL))
