Hallo,
I've created a Template to load cores Synology NAS. I recently added a condition that I not display an error in the time of the backup server. The problem is that for some reason my condition will change and I do not know why. -1 Disappears and is therefore invalid, then the trigger. I recently upgraded to version 3.2.4 zabbix. More can be seen in the video here 41eQ84CIcdw in h-t-t-p-s-:-/-/youtu-dot-be+/41eQ84CIcdw

"Unfortunately I can not give a direct link to my uploaded video with an error and dont know how to contact administrator to make me loosen."

Ales

can you post the condition and from what it change to what?
what do you see in zabbix server logs ?

I do not know how to explain this strange behavior. Have you looked at the video?

last(0)}<>1 only means not equal
try doing last(-1)}=1 or last(-1)}<>1 demands on what u need

Incorrect trigger function "last(-1)" provided in expression. Invalid first parameter.

The strange thing is that this code does work:

Code:

{Template_Synology_AU:hrProcessorLoad[{#SNMPINDEX}].avg(300)}>90 and {Template_Synology_AU:hrDeviceCore[{#SNMPINDEX}].last(0)}<>-1 and {Template_Synology_AU:hrProcessorLoad[{#SNMPINDEX}].time(0)}<230000 and {Template_Synology_AU:hrProcessorLoad[{#SNMPINDEX}].time(0)}>020000

It's bug. When I add a fifth condition, in the last conditions disappear parameter. Example Discovery Template:

Code:

{Template_Synology_AU:hrProcessorLoad[{#SNMPINDEX}].avg(300)}>90 and {Template_Synology_AU:hrDeviceCore[{#SNMPINDEX}].last(0)}<>-1 and {Template_Synology_AU:hrProcessorLoad[{#SNMPINDEX}].time(0)}<230000 and {Template_Synology_AU:hrProcessorLoad[{#SNMPINDEX}].time(0)}>020000 and 
{Template_Synology_AU:hrDeviceDescr[{#SNMPINDEX}].str("blbost")}<>1

and Host:

Code:

{fileserver.interflag.local:hrProcessorLoad[196608].avg(300)}>90 and {fileserver.interflag.local:hrDeviceCore[196608].last(0)}<>-1 and {fileserver.interflag.local:hrProcessorLoad[196608].time(0)}<230000 and {fileserver.interflag.local:hrProcessorLoad[196608].time(0)}>020000 and 
{fileserver.interflag.local:hrDeviceDescr[196608].str("blbost")}<>

again at the end missing 1

maybe like this :

Code:

({Template_Synology_AU:hrDeviceCore[{#SNMPINDEX}].last(0)}<>-1) and
({Template_Synology_AU:hrProcessorLoad[{#SNMPINDEX}].time(0)}<230000) and
({Template_Synology_AU:hrProcessorLoad[{#SNMPINDEX}].time(0)}>020000) and 
({Template_Synology_AU:hrDeviceDescr[{#SNMPINDEX}].str(blbost)}<>1)

its all about the -1
look at this thred maybe it will help :

We’ll be back soon!
