Housekeeping

[whoever]

I'm not sure if it's not implemented already. Thought I saw it in forum, but can't find any description about it anymore.

Suppose I want to keep traffic history for a year. To keep database amount to minimum I have to create 3 items:
1st: every minute get traffic keep it for 1 week;
2nd: every 5minutes get 5min avg and keep for 1 month;
3rd: every 15minutes get 15min avg and keep for 1 year.

The way I would like it to be: 1 item - every minute get traffic keep it for 1 year. And house keeping for data that is older than 1 week calculates avg for 5min and stores it instead of original data. For data that is older than 1 month - 15min avg.

ZABBIX automatically calculates 5 min average and stores it in a separate table 'trends'. You may keep detailed history for a week, and trends, say, for a couple of years.

No need to monitor all three processor loads, keep the 1st only.
