Provided I understand these configs right, you've got: BC> AVERAGE 0.5 1 5040 #1008 5040 minutes of 1 min resolution data. (i.e. 84 hours or 3.5 days)
BC> AVERAGE 0.5 12 21600 #4320 BC> MIN 0.5 12 21600 #4320 BC> MAX 0.5 12 21600 #4320 Then the next set is 12 minute steps, and you've got 180 days of 12min data. [These compress the prior 1 min steps by a factor or 1:12. Again, provided I understand correctly. This seems excessive - I'd probably keep 30 - 90 days of 12 min data. But I'm not sure what your goals are - perhaps that 12 minute data is more important than I realize. But I think I should catch most important stuff in 3 days, and after 30 days, the data's not terribly important for higher resolution needs.] BC> AVERAGE 0.5 144 3600 #720 BC> MAX 0.5 144 3600 #720 BC> MIN 0.5 144 3600 #720 Then 360 days of 144 minute (~2.3 hr resolution) data. --- Here's what I do: I keep one minute data too, and I use BC> AVERAGE 0.5 1 4320 #3 days, 60 sec resolution BC> AVERAGE 0.5 10 4320 #30 days at 10 min resolution BC> MIN 0.5 10 4320 # BC> MAX 0.5 10 4320 # [90 days might be better, but I don't often wish for more than 30-60 days] BC> AVERAGE 0.5 144 2400 #400 days at 2 hr resolution BC> MAX 0.5 144 2400 # BC> MIN 0.5 144 2400 # IIRC, this results in about 8.5MB rrd files for each monitored device. This seems like a pretty reasonable file size for me. I just calculated it, and this appears to use roughly 0.77 KB per row of data. [~770KB per 1000 RRD rows or ~1300 rows/MB.] HTH -Greg BC> Hi All, BC> Thank you for amazing piece of software! BC> I had to very aggressively test packet loss to some servers so I BC> made the following changes to the Database config. BC> *** Database *** BC> step = 60 BC> pings = 20 BC> # consfn mrhb steps total BC> AVERAGE 0.5 12 21600 #4320 BC> MIN 0.5 12 21600 #4320 BC> MAX 0.5 12 21600 #4320 BC> AVERAGE 0.5 144 3600 #720 BC> MAX 0.5 144 3600 #720 BC> MIN 0.5 144 3600 #720 BC> Basically I multiplied the steps in the config below by 5 as I BC> was reducing the step period by a factor of 5. BC> Should I do this or should I just leave the bits below at their default values? BC> Thanks in advance.
