Thanks for writing this tool. We're trying to get it to work now, but encountering an issue.
#1 Can the tool connect to influx and pull a data point? Yes, it can:

➜ check_influxdb ./check_influxdb --port 8086 --database graphite --host ***** --username root --password root --query 'select * from /servers.*****.diskspace.root.byte_percentfree/ limit 1' -w 70 -c 80

Debug output. Use -j to check value...
[
  {
    "name": “servers.*****.diskspace.root.byte_percentfree",
    "tags": null,
    "values": [
      {
    "time": "2015-08-04T23:32:47Z",
    "value": 70.84
      }
    ]
  }
]
CheckInfluxdbQuery WARNING: Check did not exit! You should call an exit code method.

#2 Can we perform a test against a data point? Yes, we can. But this is failing because we are using “select *” instead of “select x” in our query.

➜ check_influxdb ./check_influxdb --port 8086 --database graphite --host ***** --username root --password root --query 'select * from /servers.*****.diskspace.root.byte_percentfree/ limit 1' -w 70 -c 80 -j '$.test..x'

CheckInfluxdbQuery CRITICAL: Value '0' matched '80' for query 'select * from /servers.*****.diskspace.root.byte_percentfree/ limit 1'

#3 Can we change ‘*’ to ‘x’ in the query and test the data point? Sadly, no.

➜ check_influxdb ./check_influxdb --port 8086 --database graphite --host ***** --username root --password root --query 'select x from /servers.*****.diskspace.root.byte_percentfree/ limit 1' -w 70 -c 80 -j '$.test..x'

I’ve been trying this tool from CentOS 6.2, CentOS 7.1, and OSX Yosemite, all with similar results. My targets include a mix of InfluxDB 0.8 as well as 0.9 series. This particular example is against a 0.9 system. Maybe there’s just a query syntax change from 0.8 > 0.9 that is making the tool unhappy?

Any help greatly appreciated.
