Mayby we have now got the facts right and someone else mayby have the golden answer

yes, unfortunately this is a problem
strlen This function is supported since Zabbix 1.8.4.

hmm damn.. okay i will see to if i can upgrade the zabbix server, the documentation states that i don't need to upgrade my clients for that

{HP LaserJet P2055dn:display.diff(0)}>0

In this case your trigger will fire up on string value change, however, this condition has downside as well
So if value of item is "Ready " and item receives new value like "Load Paper" - trigger will fire up, however, if item receives this value again it will be acknowledged as normal and there will be no longer trigger active. And if after a while you`ll receive "Ready " again, your trigger will fire up and so on…

See diff function
http://www.zabbix.com/documentation/...onfig/triggers

there might be something i`m missing about this function and you`ll be able to accomplish your goal

I got it
{HP LaserJet P2055dn:display.str(Load Paper)}
shell work!!!!!!!!

I got it
{HP LaserJet P2055dn:display.str(Load Paper)}
shell work!!!!!!!!

I Have now upgraded my zabbix server installation to 1.8.5 and tried this one -with no luck. It does not trigger when the field changes (Can see it change allright in the Latest Data)

You did remember to put the =1 at the end, right?

{HP LaserJet P2055dn:display.str(Load Paper)}=1

Also, if Load Paper is referring to the Item key 'paper', then it would be

{HP LaserJet P2055dnaper.str(Load Paper)}=1

Failing that, keep in mind that the string is case sensitive, for example - Load paper.

That seemed to do the trick -thanks!

[Davidus]

my trigger looked exactly like this

{HP LaserJet P2055dn:display.str(Load Paper)}

I tested it and it worked for me. Trigger fired up as soon as string value appeared to be “Load Paper”

Hi,

I try to use the diplay.str parameter in trigger in Zabbix 4, but I can't find it.
I try to set if the disk status recieved as a string changes on our storage in trigger prototypes.

Please can you help me how should I do it?
Thanks.
