Copy old item History/Trends to new item

[markfree]

There was some item changes in my production Zabbix that ended up with a few duplicated items.

I have the old item which has history and trends up to 2021-01-04 when it was disabled.
The new item has data since 2020-12-29 and is enabled.

I wish to maintain only the new...

My boss wants us to keep a 10-year track record. I would like to confirm that 3500d (ie 10 years) is functional as I will have to configure the history and trends of major items like this.

Our housekeeper is still disabled. My boss wants me to activate only after placing 3500d of history...

Hi there

Since the housekeeper process runs about 3 to 6 hours each time, we have to change something in our configuration/setup. Somehow the trends and history database tables grew to

trends_uint 29 GB
trends 17 GB
history_uint 416 GB
history_text...

Trends are calculated based on all item data collected or only from data collected within one hour?...

Hello everybody,
I just like to know if is it possible to change the trend average time by default (1 hour average) to something different, like some few seconds or 1 minute, in order to have more detailed data. I'm new in Zabbix and I'm just begining to try it. Thanks in advance.

Hello,

I recently found out that I had items with the value 0d (trends) and 90d (History). This makes me only see data up to 90 days on graphs.
These items were added +5 months ago.

Therefore, I changed the trends from 0 to 365 days and now I only get data of the last...

I'm trying to get a report on the number, type and duration of tickets raised by Zabbix monitoring. I would like to know how many Disaster and High alerts have been received each day over the last month in one graph, then to have another graph that shows the duration of events. Is this possible through...

Is there any way to retrieve item trends through the API? We are new to and exploring Zabbix, version 2.0.6, and would like to remotely retrieve the reduced history over extended time for items. However, after researching it appears that item trends are not available through the API. I found the...

I changed the template in a host so as to arrange items disk.
Using unlink and clear the old items were lost, losing along the historic discs.

Seeking to improve the administration, it is possible with some trick, migrate or keep history or trends?

Thank you.

Currently if I extend the period of a graph beyond ~3.5 days my graphs display no data. Under 3.5 days and I see history data. I do not keep trends, if I enable trends then I get trend data beyond 3.5 days.

I'd like zabbix to always use historical data instead of trends for ALL time periods,...

I just changed data unit (from B to b) in some items i use to plot the bandwidth usage and I need to reset the data (history and trends) stored till now to be able to plot...
