"value" column to collectd

[kimor79]

https://github.com/influxdb/influxdb/blob/master/collectd/collectd.go#L174 adds a column named <plugin>_<value name> with the value. Some tools expect there to be a column named "value" with the value. Since the plugin and value name are already the name of the point, what about changing that line to

fields["value"] = data.Values[i].Value

Based on conversation in https://groups.google.com/d/msg/influxdb/JxRmWPom6ao/QAIw0H8Vi5QJ

(I would have submitted this as a patch but I don't have a dev/test environment at the moment)

Same applies for the graphite plugin. When sending a value for a metric named, say "cpu_load_short", the value is stored in a column "cpu_load_short" instead of "value".

Example:
echo "host.server02.region.us-east.cpu_load_short 0.64 date +%s" | nc -q0 localhost 2003

Query:
SELECT * FROM cpu_load_short

Result:

{
    "results": [
        {
            "series": [
                {
                    "name": "cpu_load_short",
                    "columns": [
                        "time",
                        "cpu_load_short"
                    ],
                    "values": [
                        [
                            "2015-04-27T13:07:37Z",
                            0.99
                        ]
                    ]
                }
            ]
        }
    ]
}

Shouldn't the value stored in a column named 'value'? Otherwise in i.e. Grafana you have to create queries such as SELECT mean(cpu_load_short) FROM cpu_load_short GROUP BY time(10s) ORDER BY asc which seems kind of redundant.

All fixed in RC29.
