Escaping # in metric instance name in telegraf.conf

[Aleyho]

Bug report

Relevant telegraf.conf:

System info: Windows Server 2012, Telegraf 1.0.0-beta3

Steps to reproduce:

While calling a inputs.win_perf_counters.object, Object type process, I'm running into a problem with having an instance name with a # as part of the instance. On a particular server I have two of the same processes running but I only need to monitor the 2nd. As I label the instance "process#1" for example naturally it comments out the rest of the line. If I attempt to escape it with "process#1" this also breaks the entire process and no results from telegraf are collected.

Expected behavior:

\ should escape the # and allow "process#1" as an instance name for a process

Actual behavior:

"process#1" as an instance name causes Telegraf to relay no data

Additional info:

[[inputs.win_perf_counters.object]]
ObjectName = "Process"
Counters = ["% Privileged Time", "% User Time"]
Instances = ["Ax32Serv#1"]
Measurement = "win_process"

what happens if you double-escape it?

[[inputs.win_perf_counters.object]]
ObjectName = "Process"
Counters = ["% Privileged Time", "% User Time"]
Instances = ["Ax32Serv\\#1"]
Measurement = "win_process"

[sparrc]

or also try it with single quotes, with no escaping:

[[inputs.win_perf_counters.object]]
  ObjectName = "Process"
  Counters = ["% Privileged Time", "% User Time"]
  Instances = ['Ax32Serv#1']
  Measurement = "win_process"

Incidentally those are the first two things I tried, but unfortunately neither worked.

that's unfortunate....might be a bug in the toml parsing library we use then 😕, don't really have time now to track it down but any PRs or additional debugging are greatly appreciated.

No worries, I'll see what I can do.

I think i have the same problem, follow config doesn't working

  [[inputs.win_perf_counters.object]]
    # Example query where the Instance portion must be removed to get data back, such as from the Memory object.
    ObjectName = "NVIDIA GPU"
    Counters = ["% GPU Usage", "% GPU Memory Usage", "Temperature (ºC)"]
    Instances = ["*"] # Use 6 x - to remove the Instance bit from the query.
    Measurement = "win_nvidia_gpu"
    #IncludeTotal=false #Set to true to include _Total instance when querying for all (*).

maybe this happens because my nvidia card instance also have # in the name!
#0 Quadro 2000 (id=1, NVAPI ID=3840)

I believe this has been fixed by #1827.
