After the user upgrades/imports log files into R80.x SmartLog/SmartEvent server, it shows logs only for the last 1-14 days (since the date of the upgrade/import).
The $RTDIR/log_indexes/ directory on R80.x SmartLog/SmartEvent server contains directories that go back only for the last 1-14 days (since the date of the upgrade/import).
If an offline job is run, the events appear in the Events tab, but not in the tabs of specific blades.
If an offline job is run to send historical log files to R80 SmartEvent server, the "Files" read as "DDD MM DD HH:MM:SS 1969" (e.g., Wed Dec 31 18:00:00 1969) and show "0" for the number of logs.
DDD MM DD HH:MM:SS 1969
Wed Dec 31 18:00:00 1969
By default, R80.x SmartLog/SmartEvent server indexes and shows logs only up to 14 days back (counting back from the date of the upgrade/import).
Starting from R80.20, only 1 day is indexed by default (fw.log only).
