snmp trigger with time delay

[karpath]

Hello everyone,

i'm using zabbix 2.4 and i'm currently using default snmp discovery trigger for a few host.

I want to do the following:
-be warn when free disk space is under 5% but only if so during 2 hours.

using

Template SNMP Disks:hrStorageUsedInBytes[{#SNMPVALUE}].last(0)} / {Template SNMP Disks:hrStorageSizeInBytes[{#SNMPVALUE}].last(0)} > 0.95

works be generate unwanted alerts due to some batch processing at night.

How can i add a time condition in this calculated trigger.

i tried a few things but none worked.

try something like

Template SNMP Disks:hrStorageUsedInBytes[{#SNMPVALUE}].max(7200)}<5

[karpath]

try something like

Template SNMP Disks:hrStorageUsedInBytes[{#SNMPVALUE}].max(7200)}<5

HI, i think this will be false; my trigger is calculated: usedpsace/totalspace give me free % left. Yours will give me an alert when the usedspaceinbytes will be less than 5, but 5 what? Bytes?

Last night i tried the following

{Template SNMP Disks:hrStorageUsedInBytes[{#SNMPVALUE}].max(7200)} / {Template SNMP Disks:hrStorageSizeInBytes[{#SNMPVALUE}].max(7200)} > 0.90

i got the alert mail at 03:24am an the recovery one at 05:28am, 2hrs later (7200 seconds)
If i understand right the max(7200) only delay the recovery email for 2 hours...

Anyone with an idea or some help?
I am certainly not the first one who encountered this problem.
