With that, I have about one week of metrics (seconds)
Would like to activate multi tier for longer retention
[db]
mode = dbengine
# Tier 0, per second data for a week
dbengine multihost disk space = 1280
storage tiers = 3
# Tier 1, per minute data for a month
dbengine tier 1 multihost disk space MB = 330
# Tier 2, per hour data for a year
dbengine tier 2 multihost disk space MB = 67
When I activate this config, I lose my history of one week.
We’ve discussed this a bit, and we think that the data are not actually lost, rather they are not returned by the query properly when asked from by the dashboard for the 1 week duration.
Can I assume also by the way you state the problem, that when you revert the changes to netdata.conf (i.e. keep only one tier as before), you get your history back?
If so, most likely, by trying a nightly build or waiting for tomorrow’s stable release, you should be good to go with enabling the extra tiers and also seeing your history (latest nightlies have changes to the query engine to properly return older data such in your case when enabling extra tiers).
I revert to the former config but the history is still lost.
I try on another server.

So, changing dbengine multihost disk space from [global] section to [db] section seems to be the problem.
However, when the change from taking this option from [global] to [db], the option name slightly changed as well. It is now: dbengine multihost disk space MB instead of dbengine multihost disk space.
So most likely that is the cause. And since when taking it in [db] section, Netdata could not read this option and defaulted to another value. Can you try with MB ?
I’m experiencing some strange display issue when I select more than last 8 hours, but not when I’m scrolling to the left or selecting an absolute start/end date. I will test the nightly rpm if I have some time otherwise I will wait the next stable.
The other issue sounds like a query engine issue. There have been lots of fixes since 1.36.1 there, we would be very interested to hear your thoughts after testing next stable!
