Difference in notifications

[Yevgeniy Semerikov]

Hello!

I'm configured an item like "vfs.file.contents[/etc/group]" and trigger for it like "{Template OS AIX:vfs.file.contents[/etc/group].diff(0)}=1". This works fine when file /etc/group changed, but in notifications I get full content of file /etc/group. There is any way to get in notifications only difference between previous and last value, e.g. UNIX diff command output?

No one know solution for this, except scripting?

I can offer unusual way to do it.
1) create an Item "group_diff" with SSH_agent type.
in "Executed script" write a command which compare two files. (diff group group_saved, for example)

2) create an item "group_backup" with ssh_agent type
in "Executed script" write a command which Backup group file, if it changes. (for example, mv group_saved group_20141231; cp group group_saved)

3) create a Trigger which will switch if "group_diff" is not empty

OK?

Thanks aib,

I'm was considering a similar path, with using a agent-side script to do this, but I was hoping that there is a built-in path.

If there no built-in way to do this, then I have to use the script.
