splunk 日常运维操作笔记。

0x01 场景

1.agent 安装

linux：

tar -zxvf splunkforwarder-8.0.3-a6754d8441bf-Linux-x86_64.tgz -C /opt
cp -r config /opt/splunkforwarder/etc/apps
vi /opt/splunkforwarder/etc/apps/prefix_app_inputs/local/inputs.conf
[monitor:///home/var/log/*log] #修改监控路径

/opt/splunkforwarder/bin/splunk start --accept-license # 输入app账号密码
/opt/splunkforwarder/bin/splunk show deploy-poll # 检查配置文件是否配置好DS指向
/opt/splunkforwarder/bin/splunk enable boot-start # 开启自启动

2.splunk接入log（读取日志文件方式）

登录DS 后台

vim /opt/splunk/etc/development-apps/prefix_all_indexes/local/indexes.conf

新增索引 [prefix_mailcasph]

[prefix_mailcasph] homePath = volume:hotwarmdb/prefix_mailcasph/db coldPath = volume:colddb/prefix_mailcasph/colddb thawedPath = $SPLUNK_DB/prefix_mailcasph/thaweddb

inputs 负责数据采集，props负责数据解析

配置inputs文件夹

vim prefix_mailcasph_inputs/local/app.conf (这个一般参考default/app.conf 不做修改)

[install]
state = enabled

[package]
check_for_updates = false

[ui]
is_visible = false
is_manageable = false

vim prefix_mailcasph_inputs/local/inputs.conf

[monitor://D:\Exchange Server\Logging\HttpProxy\Eas\HttpProxy*.log]
index = prefix_mailcasph
sourcetype = ms:exchange:http_proxy
crcSalt = <SOURCE>
disabled = false

metadata 文件夹
local.meta：[]
access = read : [ * ], write : [ admin ]
export = system

配置props文件夹

vim prefix_mailcasph_inputs/local/app.conf

[install]
state = enabled

[package]
check_for_updates = false

[ui]
is_visible = false
is_manageable = false
