function Get-GraphiteMetric { <# .Synopsis Get Graphite metrics data to send. .Description Calling this function will return metrics data for sending to Graphite. Note: Metrics input must be provided in the format '@(@{...}, @{...})', see example. .Example $graphiteMetrics = Get-GraphiteMetric -Metrics @{ name = 'test.series.1'; value = 3.14159 } -IntervalInSeconds 10 -Timestamp $timestamp Write-Host "Will send the following metrics to Graphite: $graphiteMetrics" .Example $graphiteMetrics = Get-GraphiteMetric -Metrics @( @{ name = 'test.series.1'; value = 3.14159 } @{ name = 'test.series.2'; value = 3.14159 } ) -IntervalInSeconds 10 -Timestamp $timestamp Write-Host "Will send the following metrics to Graphite: $graphiteMetrics" .Link Get-GraphiteTimestamp .Link https://grafana.com/docs/grafana-cloud/data-configuration/metrics/metrics-graphite/http-api/#adding-new-data-posting-to-metrics #> param ( # Specifies the metrics name/value pair to send.
