Which log shipper are you using, NXLOG or Filebeat?
How did you configure the Graylog Collector Sidecar?
How did you configure the log shipper (i. e. what’s the generated configuration)?
Which locale are you using on the system with the Apache httpd access logs?

Thank you for replay…
>Which log shipper are you using, NXLOG or Filebeat?
NGLOG

>How did you configure the Graylog Collector Sidecar?
the configure of Collector Sidecar as below:

server_url: http://192.168.2.9:12900
update_interval: 10
tls_skip_verify: false
send_status: true
list_log_files:
    - /var/log/httpd/
node_id: IAMANODE
collector_id: file:/etc/graylog/collector-sidecar/collector-id
cache_path: /var/cache/graylog/collector-sidecar
log_path: /var/log/graylog/collector-sidecar
log_rotation_time: 86400
log_max_age: 604800
tags:
    - linux
    - apache
backends:
    - name: nxlog
      enabled: true
      binary_path: /usr/bin/nxlog
      configuration_path: /etc/nxlog.conf

>How did you configure the log shipper (i. e. what’s the generated configuration)?
i don’t know what’s the mean of log shipper , means INPUTS?
if INPUTS,i defined it like below:

>Which locale are you using on the system with the Apache httpd access logs?
collector-sidecar OS:CentOS7.1

[root@cmdb ~]# locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

access_log is us-ascii, as below

[root@cmdb ~]# file -i /var/log/httpd/access_log
/var/log/httpd/access_log: text/plain; charset=us-ascii

and this is my snippet config:

{{end}}

also added verbatim configuration in the end of INPUT:

Exec convert_fields("AUTO", "utf-8");

i try to command the OutputType
and got right message
maybe reason is input message’s format is not mismatching to GELF??


(Xuziheng1002) #10

this issue has been resolved.
reason is collector_sidecar output into the wrong INPUT format(syslog type).
create a new type INPUT(GELF) and change collector_sidecar output to the new INPUT,everything is OK!
