Hi @renatoa12
First, please be patient. This is a community forum. Please do not ping multiple times, especially after only 1 hour In my experience, sometimes that'll actually have the opposite effect on getting help. There are many questions here and yours is no more important than any other topic.
Can you provide the actual ILM policy you defined? We can't help without seeing it.
Second, it seems like the index is still less than 2 GB, so I'm unclear why you're concerned it's not working?
Please post the ILM policy and perhaps we can help.
Go to Kibana- Dev Tools
And use this API and show us what your ILM policy is
Also as a note ILM is a background process and the data sizes may not be exact .. especially with small sizes such as 1 or 2 GB ... I would think +/- 5% or so... as indices / setting larger that percentage is small.. NOTE this is just an estimate from experience.
Here are some thoughts on the topic ...I posted a bit about it here and another elastician here
