[研究]更新 Splunk 8.1.1 後，發現 log 沒進來之解決 (Index 爆滿)
2020-12-30
更新 Splunk 8.1.1 後，發現 log 沒進來。
df 發現磁碟空間 99%。
參考
https://docs.splunk.com/Documentation/Splunk/8.1.1/Indexer/Setaretirementandarchivingpolicy
https://docs.splunk.com/Documentation/Splunk/9.0.1/Admin/Indexesconf
發現舊設定 /opt/splunk/etc/system/local/indexs.conf 不見了，可能升級整個目錄被砍掉重新安裝。
把 /opt/splunk/etc/system/default/indexs.conf 複製過來，設定可寫入，再次把預設值 6 年重新把值設回180天。(因為磁碟空間有限)
cp /opt/splunk/etc/system/default/indexes.conf /opt/splunk/etc/system/local/indexes.conf
chmod a+w /opt/splunk/etc/system/local/indexes.conf
vi /opt/splunk/etc/system/local/indexes.conf
[main]
frozenTimePeriodInSecs = 15552000
預設值188697600秒/60/60/24/365=6年
新設值15552000秒/60/60/24=180天
reboot 作業系統 Linux 後，log又進來了。df 看到也不是99%了。

不清楚 $SPLUNK_HOME 和 $SPLUNK_DB 是甚麼值？

所以實際上 index DB 存放在 SPLUNK_DB=/opt/splunk/var/lib/splunk
(完)
