Redis | redis-cli INFO / avg_ttl value

up vote1down votefavorite

when the command redis-cli INFO is run, some of the returned values indicates the avg_ttl. I'm unsure what unit of time this is represented in:

Example:

Keyspace

db0:keys=706818,expires=228745,avg_ttl=1521990750

amazon-ec2 redis nosql

This is a bit confusing indeed.

• the TTL command return value is in seconds
• PTTL command return value is in milliseconds
• avg_ttl from INFO is in milliseconds

Also, note that this average value avg_ttl is just an estimate based on random check of keys.
