Example: Scripts Pipeline

Pipeline Scripts

paStash can serve all sorts of script emitting JSON objects for distribution and post-processing. In this example, we'll use the input of ppsguard to power a gauge using the statsd protocol.

scola-pastash (colander)

input {
  udp {
    host => 127.0.0.1
    port => 1234
  }
}

filter {
  json_fields {}
}

output {
  studout {}
  statsd {
      host => localhost
      port => 8125
      metric_type => gauge
      metric_key => pps
    }
}

PPS Counter producer

npm install -g ppsguard
ppsguard --max_pps=100 --interface eth0 --udp 127.0.0.1:1234
