Interface statistics

[klalex]

Hi,

I have question where to get bandwitch statistic for each host/interface in zabbix database. What I found is history, history_uint, trends, trends_uint. Trends and trends_uint looks like have stats which are showing on the graphics but I see that this value is saving each hour and has min, avg and max. So it looks like calculated subtotal per each hour. From other side, history and history_uint has more clock points (each 5 seconds as I see) but it doesn't look to be saving for all date periods - just short period. Can you help me understand it please?

Also what is difference between history and history_unit, for example?

Thanks,
Alex

Item values are inserted into the respective history table depending on its type of information:

Numeric (unsigned) -> history_uint
Numeric (float) -> history
Character -> history_str
Log -> history_log
Text -> history_text

Values are removed from history tables according to the items 'Keep history' setting -on condition housekeeping process is enabled.

And what difference between history and trends tables? I see in history there are records saving each minute but in trends - each hour. So looks like trends are subtotals from history records per hour. Is it correct?

What I need is to get bandwitch for each interface each minute. Do I need to use history table?

Trends include the minimum, average and maximum values per hour
