Zabbix 1.8.3 : Cannot edit trigger threshold

[Kh3ops]

Hi,

I've just installed Zabbix 1.8.3 and everything's going pretty well.

The only problem is that I cannot edit triggers threshold. Let's take, for example, cpu load for one of my servers. Triggers is enabled when load > 5.

When I try to edit trigger settings, I change value to 7 or 8, then save. But when page reload, trigger comes back to 5


Any idea what I did wrong?

Thanks,

Kh3ops

I'm having the same issue - interface allows to change the threshold but doesn't save it.

RE: Zabbix 1.8.3 : update trigger threshold in the database

Here is a quick workaround for the bug:

See the URL for the update action:

http://10.0.0.27/zabbix/triggers.php?form=update&triggerid=13032&sid=e5b596e5942c2170

here you see triggerid=13032
login to the zabbix DB and run:

select expression from triggers where triggerid=13032;

I get:

EXPRESSION
-------------------------
{12550}>10


So update threshold to 20 is basic:

update triggers
set expression='{12550}>20'
where triggerid=13032;

Unfortunately your url is private, but thanks for the clue. You don't explain how to work out what triggerid refers to which host.
eg
select triggerid,description,expression from triggers where description like 'Too many processes%';
.... many lines.....
13546 | Too many processes on {HOSTNAME} | {12703}>300

I tried hunting it down from the original schema but it was taking too long. Lucky for me I only needed to change the latest, got to be a problem if it's not. Some kind of entity map would be nice

You can see the UI and get that URL from Zabbix UI:
zabbix/triggers.php?form=update&triggerid=13032&sid=e5b59 6e5942c2170

triggerid=13032 is the part you care about - it gives you the exact trigger id.

Excellent. Much obliged.

Triggers don't save but can be re-created

The problem in 1.8.3 I have is not only thresholds cannot be update (saved),
but any trigger change doesn't get persisted.

I tried to change the trigger expression, everything works properly until you hit the "save" button:

I get "Trigger updated" green message but in reality nothing changes.

I was able to work it around by creating a new trigger with the expressions I wanted though.
