Ethernet Speed Error?

[stevefxp]

Hello all,

My Zabbix server is a VM running on Proxmox. When I look at the latest data for the server it has an error on the speed of the ethernet interface. The error message is: Value of type "double" is not suitable for value type "Numeric (unsigned)". Value "-1000000". Is this an error I can resolve? I have never seen this.

Thanks,
Steve

I have the same error message. But understand where the error is comming from. This error is caused by having a device with LAN-ports without any cable in it. On my device it will register the speed on that LAN-port as "-1".
For example on my OpenWRT device:

cat /sys/class/net/lan1/speed
-1 <= no-cable/disconnected
cat /sys/class/net/lan2/speed
100 <= 100mbit
cat /sys/class/net/lan4/speed
1000 <=1gb

In the preprocessor of the item, i see the "Custom multiplier" set to "1000000". So doing the three-dimensional lineair algebra, it will result in: "-1000000". Which is a "signed" (possibly negative) number and cause the error.

As i'm pretty new to Zabbix, i've yet to find a nice solution for this. I think that replacing the value of "-1" with "0" would make sense, but will have to find out how i can do this. Probably somewhere at the item-prototype level.

Have you found a solution already?
