Netdata doesn't store data longer than 8hrs (Unraid setup)

Help

I have netdata running on Unraid and it never goes back more than 8hrs.

[Setup]
Unraid 6.12.4
Installed via docker container and up-to-date

This is what my netdata.conf [db] section looks like

[db]
	 update every = 1
	 mode = dbengine
	 dbengine multihost disk space MB = 256
	 storage tiers = 3
	 dbengine tier 1 multihost disk space MB = 128
	 dbengine tier 1 update every iterations = 60
	 dbengine tier 2 multihost disk space MB = 64
	 dbengine tier 2 update every iterations = 60

When I try to look back, my charts break off after the 8hr mark

Ideally, I’d want this to go back at least a year using the tiered storage system, which seems possible based on the documentation

Hi @frosty_hedgehog

You just need to increase the disk space MB of all tiers.

Now, how much exactly, really depends on how many metrics the agent is collecting.
