Trigger for IfOperStatus

[sgalliani]

Hi Guys,
I'm trying to figure out how trigger expressions work and i currently have a small problem,
I have to find a way to use IfOperstatus on my switches, to see if a port is no longer used, if it's not used for a certain amount of time.
For example if there is nothing connected to specific port for more than 5 days, it should send me an alert.
Would that be?
{Template SNMP Interfaces HP:ifOperStatus[{#IFDESCR}].diff(5d)}=1
Thanks in advance

you dont have this on diff:

diff
Checking if last and previous values differ.		Supported value types: float, int, str, text, log

Returns:
1 - last and previous values differ
0 - otherwise

you can try do it in diffrent ways-

1. make item check once a day and then make a trigger by last 5 values
2. make bash script for that
3. try this :

nodata (sec)
Checking for no data received.	sec - evaluation period in seconds. The period should not be less than 30 seconds.	Supported value types: any

Returns:
1 - if no data received during the defined period of time
0 - otherwise

Note that this function will display an error if, within the period of the 1st parameter:
- there's no data and Zabbix server was restarted
- there's no data and maintenance was completed
- there's no data and the item was added or re-enabled
Errors are displayed in the Info column in trigger configuration.
