please consider deprecating this repo in favor of https://github.com/seegno/sensu-influxdb-extension ?

I have this extension installed on my rhel 6 server sensu 0.12 with rvm 2.1, and 1.9.3 and the influxdb, timeout and the rubygems gems installed and when I restart the sensu-server I get the following in the logs, what am I doing wrong?

Hi,
I'm using Influxdb v0.8.8 with this handler.

this handler created a Serie with the same plugin name, exemple:
metric_cpu_pcnt
with the columns below:

time sequence_number value host metric
1421090211000 193692360001 1 i.5e2e894b.lb.tnt.portal.core.uat.sa.east.1.test.net lb.tnt-portal.core.uat.sa-east-1.cpu.total.user

I would like be a query to find a CPU consume per host like this:

select value from "metric_cpu_pcnt" where host =~ /^i.5e2e894b/ AND metric =~ /cpu.total.user$/ and time > now() - 15m;

This query is very slow because when the query use regex in the columns the regex needs to be match for EVERY measurement, and measurements for ALL "metrics" needs to be loaded.

Why this extension work this away?

The correct are not this: (serie name = hostname + metric) ?
series name: i.5e2e894b.lb.tnt-portal.core.uat.sa-east-1.cpu.total.user , columns: [time, value]

Because:
when the query use regex on the series names, not the column values, the series names are in memory in influxdb and the lookup and regex mach is quick as it only needs to be done once.

tks
Joao

I have done a "gem install influxdb", and i setup my /etc/sensu/handlers/metrics.json to look like the example. Is there something else I'm missing in this error or in the requirements?
