Logstash 6.2

[Misairu]

I discovered that existing script do not return pipeline stats with Logstash 6.2
spoiler alert: pipeline now called pipelines

https://www.elastic.co/guide/en/logstash/current/node-stats-api.html

Manual says that we do not need python and head anymore (API can transmit stats in pretty json format by itself)

That is my version of your script

#!/bin/bash

case $1 in
status )
initctl status logstash | grep -q running && echo 1 || echo 0 ;;
heap_bytes )
curl -s 'localhost:9600/_node/stats/jvm?pretty' | grep "heap_used_in_bytes | awk '{ print $3 }' | sed 's/,//' ;;
heap_percent )
curl -s 'localhost:9600/_node/stats/jvm?pretty' | grep "heap_used_percent | awk '{ print $3 }' | sed 's/,//' ;;
heap_max )
curl -s 'localhost:9600/_node/stats/jvm?pretty' | grep "heap_max_in_bytes | awk '{ print $3 }' | sed 's/,//' ;;
events_in )
curl -s 'localhost:9600/_node/stats/events?pretty' | grep "in | awk '{ print $3 }' | sed 's/,//' ;;
events_filtered )
curl -s 'localhost:9600/_node/stats/events?pretty' | grep "filtered | awk '{ print $3 }' | sed 's/,//' ;;
events_out )
curl -s 'localhost:9600/_node/stats/events?pretty' | grep "out | awk '{ print $3 }' | sed 's/,//' ;;
failures )
curl -s 'localhost:9600/_node/stats/reloads?pretty' | grep "failures | awk '{ print $3 }' | sed 's/,//' ;;
