No idea how I'm supposed to regex values.

I'm having a really difficult time trying to figure out how to use regex to get values of the same series from different hosts. or even values from the same host, for example.

I have a series in influxdb sent from collectd, CPU usage, for instance.

/localhost/cpu-0/cpu-idle
/localhost/cpu-1/cpu-idle
/localhost/cpu-2/cpu-idle

But there's no way to grab all the cores information via regex, I keep getting errors. What is supposed to be the proper regex to return all the values?

I've tried
/localhost/cpu-/cpu-idle
/localhost/cpu-./cpu-idle
/localhost/*/cpu-idle

I'm no fool to SQL, or regex. But there's no implementation of sql's LIKE, I can't find a way to fuzzy match these values. Even your examples reference "app.*" but there isn't a single value being collected that splits values out by periods, only slashes. Maybe that's another issue I need to address first?

What version of influxdb are you using?

I'm running 0.8.8.

I've found that collectd can aggregate before putting items into influxdb, so perhaps that's the better route to take.
