Telegraf not working with sysstat options like `-d` or `-n ALL`?

Question

I am attempting to setup Telegraf on a Proxmox (Debian-based distro) to send metrics to InfluxDB. However, it seems to be complaining about sysstat syntax.

I am using the sysstat plugin in Telegraf.

Per the configuration file, I have a section like this

#   ## sysstat version.
#   [inputs.sysstat.options]
#     -C = "cpu"
#     -B = "paging"
#     -b = "io"
#     -d = "disk"             # requires DISK activity
     "-n ALL" = "network"
#     "-P ALL" = "per_cpu"
#     -q = "queue"
#     -R = "mem"
     -r = "mem_util"
#     -S = "swap_util"
#     -u = "cpu_util"
#     -v = "inode"
#     -W = "swap"
#     -w = "task"
#   #  -H = "hugepages"        # only available for newer linux distributions
#   #  "-I ALL" = "interrupts" # requires INT activity

However, it appears to be erroring out on these options:

root@syd1:/var/run/ceph# telegraf --test

Yet if I run sysstat -h, I see:

        -W      Swapping statistics
        -w      Task creation and system switching statistics
        -y      TTY devices statistics

So things like -d or -n ALL are available.

Any idea what's going on?

Whoops, this was actually a syntax error in my config file. Specifically, I needed to uncomment the line:

[inputs.sysstat.options]

which comes just before the

#     -C = "cpu"
#     -B = "paging"
#     -b = "io"
     -d = "disk"             # requires DISK activity
     "-n ALL" = "network"
#     "-P ALL" = "per_cpu"
#     -q = "queue"
#     -R = "mem"
     -r = "mem_util"
#     -S = "swap_util"
#     -u = "cpu_util"
#     -v = "inode"
#     -W = "swap"
#     -w = "task"
#   #  -H = "hugepages"        # only available for newer linux distributions
#   #  "-I ALL" = "interrupts" # requires INT activity

Without it, it didn't parse the above lines correctly.

Telegraf not working with sysstat options like `-d` or `-n ALL`?
