我对 Logstash 和弹性搜索很陌生。我正在尝试将日志文件存储在elasticsearch 和平面文件中。我知道logstash 支持这两种输出。但它们是同时处理的吗?还是通过工作定期完成?
是的,您可以通过使用托运人配置上的“add_tag”命令标记和克隆您的输入来执行此操作。
input
{
tcp { type => "linux" port => "50000" codec => plain { charset => "US-ASCII" } }
tcp { type => "apache_access" port => "50001" codec => plain { charset => "US-ASCII" } }
tcp { type => "apache_error" port => "50002" codec => plain { charset => "US-ASCII" } }
tcp { type => "windows_security" port => "50003" codec => plain { charset => "US-ASCII" } }
tcp { type => "windows_application" port => "50004" codec => plain { charset => "US-ASCII" } }
tcp { type => "windows_system" port => "50005" codec => plain { charset => "US-ASCII" } }
udp { type => "network_equipment" port => "514" codec => plain { charset => "US-ASCII" } }
udp { type => "firewalls" port => "50006" codec => plain }
}
filter
{
grok { match => [ "host", "%{IPORHOST:ipaddr}(:%{NUMBER})?" ] }
mutate { replace => [ "fqdn", "%{ipaddr}" ] }
dns { reverse => [ "fqdn", "fqdn" ] action => "replace" }
if [type] == "linux" { clone { clones => "linux.log" add_tag => "savetofile" } }
if [type] == "apache_access" { clone { clones => "apache_access.log" add_tag => "savetofile" } }
if [type] == "apache_error" { clone { clones => "apache_error.log" add_tag => "savetofile" } }
if [type] == "windows_security" { clone { clones => "windows_security.log" add_tag => "savetofile" } }
if [type] == "windows_application" { clone { clones => "windows_application.log" add_tag => "savetofile" } }
if [type] == "windows_system" { clone { clones => "windows_system.log" add_tag => "savetofile" } }
if [type] == "network_equipment" { clone { clones => "network_%{fqdn}.log" add_tag => "savetofile" } }
if [type] == "firewalls" { clone { clones => "firewalls.log" add_tag => "savetofile" } }
}
output
{
#stdout { debug => true }
#stdout { codec => rubydebug }
redis { host => "1.1.1.1" data_type => "list" key => "logstash" }
}
在你的主logstash实例上你可以这样做:
input {
redis {
host => "1.1.1.1"
data_type => "list"
key => "logstash"
type=> "redis-input"
# We use the 'json' codec here because we expect to read json events from redis.
codec => json
}
}
output
{
if "savetofile" in [tags] {
file {
path => [ "/logs/%{fqdn}/%{type}" ] message_format => "%{message}"
}
}
else { elasticsearch { host => "2.2.2.2" }
}
}
