Powershell POST to pushgateway

[Leen Tux]

Hi

What is the powershell command equivalent to:
$ echo 'metricname1 101' | curl --data-binary @- http://localhost:9091/metrics/job/jobname1/instance/instancename1

I got this error :

Invoke-WebRequest -Uri 'http://192.168.1.111:9091/metrics/job/jobname1/instance/instancename1' -Method Post -Body 'metricname1 101' -ContentType 'application/octet-stream'

Invoke-WebRequest : text format parsing error in line 1: unexpected end of input stream

I am facing the same issue here:
https://stackoverflow.com/questions/68818211/send-metrics-with-pushgateway-prometheus-using-windows-console
But the solution mentioned did not work for me.

echo "metricname1 101
" | Invoke-WebRequest -Uri http://192.168.1.111:9091/metrics/job/jobname1 -Method POST

Invoke-WebRequest : text format parsing error in line 1: expected float as value,  got "101\r"

got "101\r"

suggests that you're sending a Windows newline (.....\r\n) instead of a Unix newline (.....\n), and that pushgateway isn't happy with that.

I don't know if Windows supports some mechanism for inserting explicit control sequences, such as

-Body 'metricname1 101\n'

or

echo -ne 'metricname1 101\n'
