redis input doesn't return keyspace info

[aodj]

Looking at the fields parsed from Redis it doesn't include any of the per-database keyspace metrics. Given that it's querying the INFO command the data is available, and it would be good to include it in the dataset.

It should look something like this:

# Keyspace
db0:keys=1215407,expires=1215399,avg_ttl=2498971

Please note that this isn't referring to the keyspace_hits and keyspace_misses fields which are included.

Thanks for reporting that, I may not have time to get to this for a bit, but if you have time to submit a PR I would appreciate it immensely

Was this feature added in some version of telegraf? If so, which version has it?
I'm currently using Telegraf v1.1.2 (git: release-1.1.0 3da3a22)

Specifically looking for total keys @ host.

Looks like it was added in v0.1.10. Should be part of the redis_keyspace measurement.

Is there some configuration I need to change perhaps?

Using:

[[inputs.redis]]
  ## specify servers via a url matching:
  ##  [protocol://][:password]@address[:port]
  ##  e.g.
  ##    tcp://localhost:6379
  ##    tcp://:password@192.168.99.100
  ##
  ## If no servers are specified, then localhost is used as the host.
  ## If no port is specified, 6379 is used
  servers = ["tcp://localhost:6379"]

Try SELECT * FROM redis_keyspace WHERE $timeFilter

[ericuldall]

Yep, that did it. Thank you!
