[inputs.swap]: Error in plugin: error getting swap memory info: xswdev version mismatch

[nbari]

Relevant telegraf.conf:

[[inputs.swap]]

System info:

Telegraf 1.9.3
FreeBSD 12.0-STABLE r343881 amd64

Steps to reproduce:

use swap on ZFS only:

zfs create -V 64G -o org.freebsd:swap=on -o checksum=off -o compression=off -o dedup=off -o sync=disabled -o primarycache=none tank/swap

Output of swapinfo:

# swapinfo -h
Device          1K-blocks     Used    Avail Capacity
/dev/zvol/tank/swap  67108864       0B      64G     0%

Expected behavior:

Get metrics/status from swap

Actual behavior:

E! [inputs.swap]: Error in plugin: error getting swap memory info: xswdev version mismatch

Would it be possible to run this Go program? Place the following code in a file main.go:

package main

import (
	"fmt"

	"github.com/shirou/gopsutil/mem"
)

func main() {
	res, err := mem.SwapMemory()
	if err != nil {
		fmt.Println(err)
		return
	} else {
		fmt.Println(res)
	}
}

To run it you will need Go 1.9 or later:

go get -d github.com/shirou/gopsutil/mem # downloads to ~/go
go run main.go

Can you also run freebsd-version -k -r -u and uname -a?

Hi @danielnelson, this is the output of the code:

xswdev version mismatch

The out put of freebsd-version -k -r -u:

> freebsd-version -k -r -u
12.0-STABLE
12.0-STABLE
12.0-STABLE

and uname -a:

FreeBSD dev 12.0-STABLE FreeBSD 12.0-STABLE r343685 DL360  amd64

I opened an issue with gopsutil, if you could subscribe to that issue I'm sure there will be some follow up questions.

[nbari]

Is this fixed in latest version 1.10.0 ?

[danielnelson]

Unfortunately no, we need to update gopsutil to v2.19.02. We don't normally update gopsutil on patch releases unless something major comes up, because it often causes other issues, so this will likely need to wait for 1.11. I will update master now though, are you using our official packages?

[nbari]

I use the port: https://www.freshports.org/net-mgmt/telegraf/
