Hi Zabbix support,
Seems like the default Linux interface discovery template has a small issue. Some systems might give back their interface speed item as a negative value. Seems like this means it cannot be detected and it throws an error:
I think it's a discussion wether or not the unsupported item is fine like this, but it seems cleaner to use a pre-processing step "Check for not supported values" Related ticket: Regards,

Hi, I'm having the same issue, the content of the file /sys/class/net/eth0/speed is -1 in all the VMs. Some short and good info about it. |

Similar issue, with the status toggling: {{389222:20250221:082312.593 item "HOST:vfs.file.contents["/sys/class/net/enp1s0/speed"]" became not supported: Value of type "string" is not suitable for value type "Numeric (unsigned)". Value "-1000000" }} |

got this on every ubuntu 18-24. check 'vfs.file.contents["/sys/class/net/enX0/speed"]' is not supported: Cannot read from file: read /sys/class/net/enX0/speed: invalid argument |
