Aggregate Item and Trigger

[clahti]

Hello all:

We have a storage device that returns some SNMP information, for example:

vol01:Name = "My Test Volume"
vol01:Size = 10000 (MB)
vol01:Used = 2500 (MB)

You can see in the above example that the volume is 25% used or 75% free, depending on how you look at it . What I need to do now is:

1. I need an item to calculate either the percentage used or free on this volume
2. create a trigger if free percentage is less than 10% or percentage used is more than 90% (take your pick)
3. this may be a stretch but I would love for the trigger email to say something like {HOSTNAME} Free Disk Space Low on {vol01:Name.value()}

I am at a loss on how to do this, can this be done with zabbix? I am guessing this would be done with aggregate items but I have no idea how to get this going.

Thanks for any help!

Hello,

You can create a Calculated item that looks like this:

100*(last("vol01:Used")/last("vol01:Size"))

Then add any trigger for that item.
