What is the difference between re-index method

[eb2020]

Hello,

Can someone explain what is the difference between re-index method at the Associated Data Queries,
and how it affects graph displaying.


Thanks

None means your primary key never changes, say for example username. Uptime goes backwards means the primary key can change on device restart, and Verify fields is horrific validation every poller cycle. For non-snmp stuff I use None and then manually reindex in crontab periodically just to pick up new indexes.
