Could not change trigger

[admin_locean]

I have zabbix 1.8.2 on Debian Squeeze.

Sorry, may be it's a silly question, but I'm novice at Zabbix and there is a little thing that I don't understand.

I could not change a trigger.

For example I have created a trigger "Processor load is too high on {HOSTNAME}"

The expression of trigger is simple:
{my_server:system.cpu.load[,avg1].last(0)}>4

Now for example, I'd like to change 4 for 2.

I could choose "Toggle input method" -> Edit -> change the value 4 for 2 -> Replace. It seems changed.
Then I click "Save"

But when I'm back to page of triggers, the value is 4 as before.

Finally I think I could change value using "Clone". I make a Clone of my trigger, I change the value, and then I delete my old trigger.
But it seems a little bit illogical.

So I summarize. I have two question:
a) how to change trigger?

b) if the solution is only to clone, change then delete the old trigger... What is the logic?

As I said, sorry if the question is silly.
Thank you for your help.

I have never used “Toggle input method” to change trigger; what I`m basically doing in order to update trigger is simply changing value in expression.
You don’t have to clone your trigger in order to apply changes.

Hmmm...

The problem is that I could not change it otherwise.

I put a little screenshot here.



The "Expression" field is grey (seems to be disable), I could put a cursor there but could not change anything.

Other possibility, use a "Select" button. In this case, I could change expression, even if I have to redefine it entirely, not only value.... but the problem that even with Select button the changes are not saved.

Just...like this trigger is read-only mode, but I don't see anything like read-only/read-write modes for triggers.

So I'm still confused about changing the triggers.

weird…
does this problem being distributed for all of you triggers? Are you using default zabbix admin user?

Yes, it seems so... I did some tests with another trigger and the behaviour is the same.

Are you using default zabbix admin user?

Yes. So for me I have a full rights for all of stuff...

Ok. Finally I got an answer in russian-language part of forum.

The problem was that I've tried to edit the trigger at the host-based level. But for this host this trigger was inherited (I don't know is this a good verb) from template.
And it's not possible to edit it on host level but only on template one.

So when I accessed this trigger via template, I could edit it and the changes, of course, have been taken in host inherited trigger.

Nevertheless, thank you very much for help.
