processes: null (Linux)

[codeisallaround]

Trying out current master (latest commit e9cf24b on Mar 27 2017) the "processes" object is not set.

With debug output enabled it looks like this:

{
  "system": {
     ...
  },
  "processes": null,
  "host": {
    ...
  },
  "plugins": {},
  "checks": null
}

I see the '"processes": null,' on Ubuntu Linux 17.04 and Raspbian. I read that the processes listing isn't for Windows yet, but it should work for Linux - right? I used 'go get github.com/amonapp/amonagent' and added the missing packages also with go get. I altered a path in makefile (building works fine) and altered address in the conf file to point to a local script that just writes down the POST data to a log file.

@codeisallaround Can you try listing them with pidstat -ruhtd? The agent relies on sysstat for process metrics

Thanks, it was my mistake.

I just looked at the makefile. The deb would install systat. I had compiled the arm binary from source and run it without using the deb file. With systat enabled it, processes object is filled with data.

I closed it too early.

pidstat -ruht shows me correct values but amonagent's JSON lists gives me only 0 or 0.00 as values. e.g. for Firefox:

Edit2: With number format set to US-english it works, but not with using a non-US format (number separator ',' instead of '.').

{
"cpu":0,
"memory_mb":"0.00",
"kb_read":0,
"kb_write":0,
"name":"firefox"
}
...

...

Edit: It might be because my Linux uses non-US regional format for numbers and dates (number separator ',' instead of '.')

@codeisallaround Can you try with the precompiled ARM binary from releases: https://github.com/amonapp/amonagent/releases

I will take a look, I usually optimize for both separators - . and ,, because my Linux install also uses non-US regional format as well
