Dashboard last 20 issues and trigger state

[windsurf51]

Hey

I have a problem with refresh of dashboard ,

if status does not change (problem is still there) , information of item can be different , but dashboard does not refresh this new value instead of triggers view ( i use {ITEM.VALUE} in trigger name)

Is there any patch or trick to allow dashboard to display last value of item/trigger?

Thx

Ok now i 'm now using ITEM.LASTVALUE for my triggers but because of that , events are showing last value too

=> i can't know previous value of trigger during first event


is there any option to display :

-triggers with ITEM.LASTVALUE ? (actual value)
-events with ITEM.VALUE ? (value at problem time )

well... you could try using both macros in the trigger name, maybe

Yep !

thats what i did

i add {ITEM.LASTVALUE} ( {ITEM.VALUE} ) in trigger name

Thx

Well i found a trick to only display ITEM.LASTVALUE in dashboard and triggers , and have ITEM.VALUE on events parts


-i add a new function in triggers.inc.php with a copy of expand_trigger_description_by_data function

-then i modify ITEM.LASTVALUE part as if it was a ITEM.VALUE:

if(zbx_strstr($description, '{ITEM.LASTVALUE}')){

$value=($flag==ZBX_FLAG_TRIGGER)?
trigger_get_func_value($row['expression'],ZBX_FLAG_TRIGGER,1,1):
trigger_get_func_value($row['expression'],ZBX_FLAG_EVENT,1,$row['clock']);

$description = str_replace('{ITEM.LASTVALUE}',
$value,
$description);
}

-then i used this function in events.php instead of normal function.


Hope it will be useful for you too!
