I’d like to use Netdata for historic data and found the article below about dbengine:
The provided calculator indicates I need 211MiB per day for “dbengine multihost disk space”, however the value seems to depend on “page cache size”. There is no recommendation on “page cache size” except for the default value is 32MiB. I’d like to ask how do I know what to set for “page cache size” if I’d like to store past 30 days metrics in Netdata? Thank you!
