I want to write a trigger with system.uptime

[karzer]

Hi, I want to write a trigger with system.uptime, down from 900 last value must be given if notification closes and final value of 400 is opened up when I want to give the warning I wonder how can we do?

system.uptime.last (0))> 400 (open)
system.uptime.last (0)) <800 (closes)

Hi Karzer,
I'm not at all sure if I understand, what your question is but I'm giving it a try:

You want a trigger, that turns "ON" at uptime 400 sec.
and back "OFF" at 900 sec. That would be:

{Jysles:system.uptime.last(0)}<900 & {Jysles:system.uptime.last(0)}>400

("Jysles" is my machine, replace it with the name of yours)

If that was not what you asked, try once more

cu, Jerry

(Jysles: system.uptime.last (0)) <900 & (Jysles: system.uptime.last (0))> 400

This trigger only works between 900 and 400. I want to exceed 400 when it opened as a warning I want to give. 900 reputation has been closed down under the thoughts I want to give warnings. ACTIONS I'm also a warning. My purpose of opening and closing of real time server monitoring and to intervene accordingly.

I'm so sorry I really don't understand you.

Hi Karzer,
Try the following example:

({TRIGGER.VALUE}=0&{server:system.uptime.last(0)}>400)|({TRIGGER.VALUE}=1&{server:system.uptime.last(0)}<800)

restart control

Hi,
I created the following trigger, how can we do better work?

({Template_Windows:status.last(0)}=0&{Template_Windows:system.uptime.last(0)}>200) |({Template_Windows:status.last(0)}=1&({Template_Windows:system.uptime.last(0 )}<2000))

If the host is not close to the warning.

Hello guys,

I am trying to create a trigger for system uptime item to detect a reboot and dont wanna use the uptime<10m means a reboot because its not effective in many ways.

I was wondering if you guys have any suggestions? I have came up with this idea :
checking the previous value not to be 0 or null AND the change value from last to previous is below 0 (negative value)

{HOST:system.uptime[sysUpTime].prev()}<>0 and {HOST:system.uptime[sysUpTime].change()}<=0

But ! there is an issue with the nodes that dont have previous value for uptime to refer to, they all trigger the alert!
----------------------

getting back to my question, I need an expression to detect reboot based on system uptime value change , in a way that it wont trigger for hosts with no initial uptime data

Zabbix version is 4.4

Where did you get the expression "uptime<10m"? In default templates used expressions system.uptime.change(0)}<0

Hi there, thanks for responding
In generic device SNMPv2 template {HOST:system.uptime[sysUpTime].prev()}<10m
is the default expression.
Do you have any idea of a better expression that can meet both conditions?
