monitor/graph ipaddr changes to interface

[me2017]

I have a UserParameter that returns an ip address from a given interface. I'd like to use some method of tracking 1) the address itself, 2) how long that address was applied / when it changed.

I've tried using the following in the Item configuration but no graph is being produced. Indeed, I didn't fully expect this to work.

Type of information: Numeric (unsigned)
Data type: Octal

I realize this may be a bit unconventional and may not be within the realm of Zabbix's capabilities. If you have seen a visualization of something like this I'd like to know how it might be done (eg, various Grafana plugins, some other network monintoring tool, etc).

I realize this may be an unconventional question but I'd appreciate comments with regards to ways to deal with this issue. Yes I have logs but I'd like to find a means of using other visualizations.

Hi,

You can monitor the address itself as a char type item (because 127.0.0.1 is not an integer or octal , it is interpreted as a string value by Zabbix).

Then you can create second calculated item with diff function:

https://www.zabbix.com/documentation/3.2/manual/appendix/triggers/functions

https://www.zabbix.com/documentation/3.2/manual/config/items/itemtypes/calculated

And use some trigger if diff function returns 1.
You can graph this calculated item, there will be straight line with spikes from 0 to 1 on each IP address change.

This is helpful, thank you. The method you've described will tell me WHEN (and IF) it changed, but it doesn't tell me what it CHANGED TO.

I wonder if this is possible in Zabbix...

Is there a means of providing some sort of visualization (a graph or other) that would reflect the following:
