Build Status Test Coverage

This is a PowerShell module for interacting with the time-series database platform Influx: At the moment the primary purpose is to enable a consistent experience for writing metrics in to Influx via the REST API, UDP or StatsD.


This module was written to allow metrics from different sources to be written to InfluxDB, for presentation via one or more Grafana Dashboards. By utilising this module, InfluxDB and Grafana you can create and populate interactive dashboards like these (note: sensitive data has been redacted from these screenshots):

For more details on how to implement these tools, check out my blog post. For more information on how to use the Influx PowerShell module, read on below.


The module is published in the PSGallery, so if you have PowerShell 5 can be installed by running:

Install-Module Influx -Scope CurrentUser


There are 3 methods for writing to Influx currently implemented:

  1. Write-Influx which uses the Influx REST API to submit metrics via TCP.
  2. Write-InfluxUDP which transmits metrics to an Influx UDP listener.
  3. Write-StatsD which transmits metrics via UDP to a StatsD listener (the StatsD listener can be enabled via the Influx Telegraf component -- see the Statsd Server section in the telegraf.conf).

For example:

Write-Influx -Measure Server -Tags @{Hostname=$env:COMPUTERNAME} -Metrics @{Memory=50;CPU=10} -Database Web -Server http://myinflux.local:8086 -Verbose

#REST API with authentication
Write-Influx -Measure Server -Tags @{Hostname=$env:COMPUTERNAME} -Metrics @{Memory=50;CPU=10} -Database Web -Server http://myinflux.local:8086 -Credential (Get-Credential) -Verbose
#Influx UDP
Write-InfluxUDP -Measure Server -Tags @{Hostname=$env:COMPUTERNAME} -Metrics @{Memory=50;CPU=10} -Database Web -IP -Port 8089 -Verbose
#StatsD UDP
Write-Statsd "Server.CPU,Hostname=$($env:COMPUTERNAME):10|g" -IP -Port 8125 -Verbose

This project was created so that PowerShell could be used to routinely query various infrastructure metrics and then send those metrics in to Influx for storage, where they could then be presented via a Grafana dashboard.

As such the module also contains a number of cmdlets for retrieving data various sources. Current implementations include: VMWare, 3PAR, Isilon and TFS. You will find these cmdlets under \Public\<source>.

The Get-SomeMetric cmdlets return a Metric type object which can be consumed by any of the Write-* cmdlets above via the pipeline or the `-InputObject' parameter. For example:

# Get metrics for VMWare Datastores and write to Influx via the REST API
Get-DatastoreMetric | Write-Influx

# Get metrics for 3PAR Systems and write to Influx via the Influx UDP listener
Get-3ParSystemMetric -SANIPAddress '' -SANUserName someuser -SANPasswordFile 'C:\some3parpasswordfile.txt' | Write-InfluxUDP

# Get TFS Build data and send to Influx via StatsD (note that Write-StatsD converts the metric object received via the pipleine to StatsD formatted strings automatically)
Get-TFSBuildMetric -TFSRootURL 'https://mytfsurl.local/tfs' -TFSCollection somecollection -TFSProject someproject -Database tfs | Write-StatsD -Type g

There are also Send-SomeMetric cmdlets that were implemented to retrieve metrics from a datasource and send it to Influx via the REST API in one step. These continue to exist for backwards compatibility, but for more flexibility use the Get-SomeMetric cmdlets and pipe their results to whatever Write-* method you want to use for interacting with Influx.

Results of other Powershell commands or custom objects can be sent to Influx. Simply map the object properties to a Metric object using the ConvertTo-Metric cmdlet.

#Send data from Get-Process to InfluxDB using the REST API with authentication
Get-Process -Name <__Processname__> | ConvertTo-Metric -Measure test -MetricProperty CPU,PagedmemorySize -TagProperty Handles,Id,ProcessName | Write-Influx -Database windows_system_monitor -Server http://<__InfluxEndpoint__>:8086 -Credential (Get-Credential) -Verbose

Implementation Example

Here is an example script which could be run as a scheduled task every 5 minutes to send stats from various sources in to Influx. Note this requires a number of dependent modules be present such as the VMWare PowerShell cmdlets.

This script uses the Send-SomeMetric cmdlets which combine the equivalent Get-SomeMetric cmdlet with Write-Influx to transmit metrics in one command via the REST API.

Import-Module Influx

Connect-VIServer | Out-Null


Send-3ParSystemMetric -SANIPAddress '' -SANUserName someuser -SANPasswordFile 'C:\some3parpasswordfile.txt'

Import-Module SSLValidation

Send-IsilonStoragePoolMetric -IsilonName someisilon -Cluster test -IsilonPasswordFile 'C:\someIsilonpasswordfile.txt'

Send-TFSBuildMetric -TFSRootURL 'https://mytfsurl.local/tfs' -TFSCollection somecollection -TFSProject someproject -Database tfs


A full list of implemented cmdlets is provided below for your reference. Use Get-Help <cmdlet name> with these to learn more about their usage.

Cmdlet Description
Get-3ParSystemMetric Returns a metric object for 3PAR systems.
Get-3ParVirtualVolumeMetric Returns a metric object for 3PAR virtual volumes.
Get-DatacenterMetric Returns a metric object for VMWare datacenters.
Get-DatastoreClusterMetric Returns a metric object for VMWare datastore clusters.
Get-DatastoreMetric Returns a metric object for VMWare datastores.
Get-HostMetric Returns a metric object for VMWare hosts.
Get-IsilonStoragePoolMetric Returns a metric object for Isilon storage pools.
Get-ResourcePoolMetric Returns a metric object for VMWare resource pools.
Get-TFSBuildMetric Returns a metric object for TFS builds.
Get-VMMetric Returns a metric object for VMWare virtual machines.
Send-3ParSystemMetric Sends metrics via the Influx REST API for 3PAR systems.
Send-3ParVirtualVolumeMetric Sends metrics via the Influx REST API for 3PAR virtual volumes.
Send-DatacenterMetric Sends metrics via the Influx REST API for VMWare datacenters.

Send-Statsd Alias of Write-StatsD (for backwards compatibility).
ConvertTo-StatsDString Converts a metric object output from one of the Get-SomeMetric cmdlets to StatsD string format. This is also performed automatically if a metric object is piped to Write-StatsD.
ConvertTo-Metric Converts the specified properties of any object to a metric object, which can then be easily transmitted to Influx by piping to one of the Write- cmdlets.
ConvertTo-InfluxLineString Convert metrics to the Influx line protocol format, output as strings.
