NOTE: This applies to both open source and commercial editions of Chocolatey.

1. Ensure you are set for organizational deployment

Please see the organizational deployment guide

  • Open Source or Commercial:
    • Proxy Repository - Create a proxy nuget repository on Nexus, Artifactory Pro, or a proxy Chocolatey repository on ProGet. Point your upstream to https://chocolatey.org/api/v2. Packages cache on first access automatically. Make sure your choco clients are using your proxy repository as a source and NOT the default community repository. See source command for more information.
    • You can also just download the package and push it to a repository Download

3. Enter your internal repository url

(this should look similar to https://chocolatey.org/api/v2)

4. Choose your deployment method:


choco upgrade aws-monitor-diskusage -y --source="'STEP 3 URL'" [other options]

See options you can pass to upgrade.

See best practices for scripting.

Add this to a PowerShell script or use a Batch script with tools and in places where you are calling directly to Chocolatey. If you are integrating, keep in mind enhanced exit codes.

If you do use a PowerShell script, use the following to ensure bad exit codes are shown as failures:


choco upgrade aws-monitor-diskusage -y --source="'STEP 3 URL'" 
$exitCode = $LASTEXITCODE

Write-Verbose "Exit code was $exitCode"
$validExitCodes = @(0, 1605, 1614, 1641, 3010)
if ($validExitCodes -contains $exitCode) {
  Exit 0
}

Exit $exitCode

2016-05-16 DarwinJS.  Version 1.2.0
   - Corrected script help - was an unedited paste of mon-put-metrics-mem
   - Added help examples for new functionality.
   - Fixed to find .NET 3.5 with newer installs of AWS SDK on Amazon AMIs.
   - allows -disk_drive 'all' to simple upload stats on all local disks - whatever they are for that instance.
     Will also dynamically adjust if disks are added to or removed from instance in the future.
   - drops any non-existent disks from the list given in -disk_drive, rather than generating an error.
   - removed assumption of credentials being provided so that code can rely on the much better practice of using instance roles.
   - replaced all "write-host" lines with better practice "write-output".
   - updated parameters and defaults so that if the script is used with no parameters it reports disk utilization for
     all installed disks and relies on instance roles for permission to post to cloudwatch.
   - switch -selfschedulewiththeseparams schedules the script in the task scheduler instead of running.  Uses all parameters
     given on the script call in the scheduled task (except, of course the parameter "-selfschedulewiththeseparams" itself)

.SYNOPSIS
Collects disk utilization (%), available disk space and used disk space on an Amazon Windows EC2 instance and sends this data as custom metrics to Amazon CloudWatch.

.DESCRIPTION
This script is used to send custom metrics to Amazon Cloudwatch. This script pushes disk utilization (%), available disk space and used disk space to cloudwatch.
This script can be scheduled or run from a powershell prompt.
When launched from scheduler you can optionally specify logfile and all messages will be logged to logfile. You can use whatif and verbose mode with this script.

.PARAMETER disk_util
		Reports disk utilization in percentages.
.PARAMETER disk_used
		Reports disk space used.
.PARAMETER disk_avail
		Reports available disk space.
.PARAMETER disk_space_units
		Specifies units for disk metrics.
.PARAMETER disk_drive
		List of disk specifiers for which to report space.  Special value 'all' reports for all local disks.
.PARAMETER from_scheduler
		Specifies that this script is running from Task Scheduler.
.PARAMETER aws_access_id
		Specifies the AWS access key ID to use to identify the caller.
.PARAMETER aws_secret_key
		Specifies the AWS secret key to use to sign the request.
.PARAMETER aws_credential_file
		Specifies the location of the file with AWS credentials. Uses "AWS_CREDENTIAL_FILE" Env variable as default.
.PARAMETER logfile
		Logs all error messages to a log file. This is required when from_scheduler is set.
.PARAMETER scheduletaskwiththeseparams
		Schedules this script to run in the Windows Scheduler.
.PARAMETER scheduletaskwiththeseparams
  	Unschedules a previously schedule job.

.EXAMPLE
    powershell.exe .\mon-put-metrics-disk-darwinjs.ps1  -EC2AccessKey ThisIsMyAccessKey -EC2SecretKey ThisIsMySecretKey -disk_space_util -disk_space_avail -disk_space_units kilobytes

    Encoded credentials are a bad idea.  This script works with Instance Roles as well (V1.2.0).

.EXAMPLE
	powershell.exe .\mon-put-metrics-disk-darwinjs.ps1  -aws_credential_file C:\awscreds.conf -disk_drive C:, d -disk_space_util -disk_space_used -disk_space_avail -disk_space_units gigabytes

    Encoded credentials are a bad idea.  This script works with Instance Roles as well (V1.2.0).

.EXAMPLE
	powershell.exe .\mon-put-metrics-disk-darwinjs.ps1  -aws_credential_file C:\awscreds.conf -disk_drive C:,D: -disk_space_util -disk_space_units gigabytes  -from_scheduler -logfile C:\mylogfile.log

    Encoded credentials are a bad idea.  This script works with Instance Roles as well (V1.2.0).

.EXAMPLE
	powershell.exe .\mon-put-metrics-disk-darwinjs.ps1

     V1.2.0: Posts *usage* metrics for all local drivers - whatever they are in gigabytes.  Will automatically handle differences in attached disks.

.EXAMPLE
	powershell.exe .\mon-put-metrics-disk-darwinjs.ps1  -disk_drive all -disk_space_util -disk_space_units gigabytes -from_scheduler -logfile C:\mylogfile.log

    V1.2.0: Posts metrics for all local drivers - whatever they are.  Will automatically handle differences in attached disks.

.EXAMPLE
	powershell.exe .\mon-put-metrics-disk-darwinjs.ps1 -scheduletaskwiththeseparams -disk_drive all -disk_space_util -disk_space_units gigabytes -from_scheduler -logfile C:\mylogfile.log

    V1.2.0: Schedules a job every 5 minutes to post disk utilization for all local drives every 5 minutes.  Does not run the metrics when scheduling the job (but the scheduled job does post them).
.EXAMPLE
  powershell.exe .\mon-put-metrics-disk-darwinjs.ps1 -unschedule

    V1.2.0: Unschedules a previously scheduled job.

.NOTES
    PREREQUISITES (should be available ahead of time for any Amazon provided AMIs):
    1) Download the SDK library from http://aws.amazon.com/sdkfornet/
    2) Obtain Secret and Access keys from https://aws-portal.amazon.com/gp/aws/developer/account/index.html?action=access-key
