Sidecar confusion


#1

Trying to figure out, what’s wrong with my simple Sidecar setup, which fails with error:
Collector Status: At least one backend with errors
Filebeat: Unable to start collector after 3 tries, giving up!

Status data and Log filenames from source server are listed on Collector Status screen, server port in /generated/filebeat.yml file changes from 5555 to 5044, if modified via Graylog Collector ”Configure Beats Outputs” - so tags should be o.k.
But Filebeat prospectors of generated yml file are empty and logs on both sides doesn’t provide much additional data.
It seems Beats Inputs configuration isn’t reflected in /generated/filebeat.yml file and filebeats can’t start. What could be the reason?

/etc/graylog/collector-sidecar/generated/filebeat.yml:

filebeat:
  prospectors: []
output:
  logstash:
    hosts:
    - 10.201.40.11:5555
path:
  data: /var/cache/graylog/collector-sidecar/filebeat/data
  logs: /var/log/graylog/collector-sidecar
tags:
- mysql-slow-query

/etc/graylog/collector-sidecar/collector_sidecar.yml:

server_url: http://10.201.40.11:9000/api/
update_interval: 10
tls_skip_verify: true

      binary_path: /usr/bin/filebeat

Picture of Inputs:

Log source server: Ubuntu 14.04. with Sidecar 0.1.4., run as root.
Graylog server v2.3.2, CentOS - iptables, firewall and selinux are disabled.


#2

Got it - removal of “Enable multiline” tick did magic and Filebeat backend status became green.
Magic was dirty and graylog got all records in a split form :frowning_face:
Problem were caused by wrong multiline configuration.

BTW nxlog backend in Sidecar behaves differently with wrong multiline configuration - it shows green status, but nothing comes in.
