Possible prometheus memory/connection leak

[jchauncey]

I am getting reports of our telegraf image running out of connections which seems to also exhibit itself as a memory leak.

A sample configuration would look like this -

# Set Tag Configuration
[tags]
# Set Agent Configuration
[agent]
  interval = "10s"
  round_interval = true
  metric_buffer_limit = 100000
  collection_jitter = "0s"
  flush_interval = "10s"
  flush_jitter = "0s"
  debug = false
  quiet = true
  flush_buffer_when_full = true
  hostname = "gke-jchauncey-default-pool-1a59a2f1-vxme"
# Set output configuration
[[outputs.influxdb]]
  urls = ["http://10.167.247.17:80"]
  database = "kubernetes"
  precision = "ns"
  timeout = "5s"




# Set Input Configuration
[[inputs.netstat]]
[[inputs.swap]]
[[inputs.system]]
[[inputs.mem]]
[[inputs.cpu]]
  percpu = true
  totalcpu = true
[[inputs.disk]]

[[inputs.diskio]]


[[inputs.net]]

[[inputs.influxdb]]
  urls = ["http://10.167.247.17:80/debug/vars"]
# Set Service Input Configuration

I'll explore this a bit more and see if I can nail down more concrete issue.
