[smokeping-users] Smokeping only keeping ~8 weeks of data

Your database section isn't configured to save data any older than 72 days.

1008 minutes of full res data [Just under 17 hours - that's kind of an odd number, but whatever.]
36 days of 12m data
72 days of 144m data

If you want to have more data, you're going to have to change the database section to keep more rows.

Your step is 60s - so 1008 samples of 60s data.
Then 4320 rows averaging 12m of data. (4320*12=Total minutes of data. That comes out to 36 days worth.]
Then 720 rows of 144m averaged data. [720*144=Total minutes of data. That comes out to 72 days.]

I'll leave it as an exercise to figure out how many rows you'll need to keep of each sample type to have history long enough to cover the time-frame you want.

But, for example. the 144m samples - if you want 2 years of data [365*2] - you'd need 
365 days * 2 = 2 years or 730 days
730 days * 24 hours = 17520 hours.
17520h * 60minutes = 1,051,200 minutes in 2 years.
Now divide those minutes by 144, and that's how many rows you'll need, if you want two years of 144m averaged data.
(i.e. 7300)
***That all assumes you continue to use 60s step times. If you change the step, you'll have to recalculate given the new step size.
If you change your step, you'll either have to re-sample your data, or more likely, dump the old data and let it rebuild the RRD files again with the proper structure and lose the historical data.

Hi All,

I am having an issue with smokeping not displaying any graphs older than ~8 weeks. I have it configured to display graphical data for 3hrs, 30hrs, 10days and 400days. 
So far, it does not show anything before the 7th week(in February 2020). 

Is there anything I have configured wrongly here?
