Alarm after a special timeperiod

[Hawky]

Hi,

I'm playing around with zabbix at the moment, its a great tool, but I looking for some features.

I want to monitor the CPU Treshold, and if the load is over 90% for 60min I want to send an alert.

Is this possible to configure zabbix that way? That it send alarms after a time period?

Thanks,

regards,
Hawky

I would use something like that:

{host:system.cpu.util[,idle,avg1].max(3600)}<10


Trigger is true if over the past hour, idle percentage has never been above 10% (that is: CPU usage has never been below 90%).

Nice! Thank you

Hi,

i played aound a bit with that trigger but I have one strange problem.

I monitor the bandwithusage of my server, in bit/s, te server is connected with a 100Mbit link, that means I've a maximum capacity of 100 000 000bit/s so I created following trigger:

{{HOSTNAME}:net.if.out[eth0].max(3600)}&gt;80000000</expression>

Anything wrong? I don't think so?

net.if.out[eth0] actually means net.if.out[eth0,bytes]. So you get the amount of incoming data (in bytes).

So if you want traffic as bits per second, you have to:
- set type to float
- set multiplier to 8 to go from bytes to bits
- set storage as delta (speed per second)

thanks for your answer, but I think you got me wrong, how to get the bandwith in bits is clear, it works already, but my trigger doesn't work.

I always get an mail when the usage is over 80Mbit but I only wants a message if the usage is over 80Mbit for 1hour, i think zabbix ignores the max(3600) in my trigger.

.max(3600)>80M will be true if over the last hour there was traffic above 80M over even a single minute.

What you want is: .min(3600)>80M

"Trigger is true if over the last hour traffic as never been lower than 80M", that is to say "Minimum traffic over the last hour as always been above 80M".

oh ok thanks, I'll try it tomorrow
