How IT administrators can streamline operations using the LogicMonitor API
In this article, we’re going to review how LogicMonitor administrators can maximize efficiency and transform their IT operations using LogicMonitor’s REST API and PowerShell. We will cover the following use cases: Device onboarding/offboarding User management Retrieving dataLogic.Monitor (PowerShell) module
If you're a LogicMonitor user looking to streamline your workflows and automate repetitive tasks, you'll be pleased to know that there's is a PowerShell module available to help you do just that. As a longtime Windows administrator, I've relied on PowerShell as my go-to tool for automating and managing my infrastructure. I've found that the ability to automate tasks through PowerShell not only saves time, but also reduces errors and ensures consistency across the environment. Developed by myself as a personal side project, this module provides a range of cmdlets that can be used to interact with the LogicMonitor API, making it easier than ever to manage your monitoring setup directly from the command line. Whether you're looking to retrieve information about your monitored devices, update alert thresholds, or perform other administrative tasks, this module has you covered. In this post, we'll take a closer look at the features and capabilities of this module, and show you how to get started with using it in your own automation scripts. This project is published in the PowerShell Gallery at https://www.powershellgallery.com/packages/Logic.Monitor/. Installation From PowerShell Gallery: Install-Module -Name "Logic.Monitor" Upgrading: #New releases are published often, to ensure you have the latest version you can run: Update-Module -Name "Logic.Monitor" General Usage: Before you can use on module commands you will need to be connected to a LM portal. To connect your LM portal use the Connect-LMAccount command: Connect-LMAccount -AccessId "lm_access_id" -AccessKey "lm_access_key" -AccountName "lm_portal_prefix_name" Once connected you can then run an appropriate command, a full list of commands available can be found using: Get-Command -Module "Logic.Monitor" To disconnect from an account simply run the Disconnect-LMAccount command: Disconnect-LMAccount Examples: Most Get commands can pull info by id or name to allow for easier retrieval without needing to know the specific resource id. The name parameters in get commands can also accept wildcard values. Get list of devices: #Get all devices Get-LMDevice #Get device via id Get-LMDevice -Id 1 #Get device via hostname Get-LMDevice -Name device.example.com #Get device via displayname/wildcard Get-LMDevice -DisplayName "corp*" Modify a device: #Change device Name,DisplayName,Descrition,Link and set collector assignment Set-LMDevice -Id 1 -DisplayName "New Device Name" -NewName "device.example.com" -Description "Critical Device" -Link "http://device.example.com" -PreferredCollectorId 1 #Add/Update custom properties to a resource and disable alerting Set-LMDevice -Id 1 -Properties @{propname1="value1";propname2="value2"} -DisableAlerting $true ***Using the Name parameter to target a resource during a Set/Remove command will perform an initial get request for you automatically to retrieve the required id. When performing a large amount of changes using id is the preferred method to avoid excessive lookups and avoid any potential API throttling. Remove a device: #Remove device by hostname Remove-LMDevice -Name "device.example.com" -HardDelete $false Send a LM Log Message: Send-LMLogMessage -Message "Hello World!" -resourceMapping @{"system.displayname"="LM-COLL"} -Metadata @{"extra-data"="value";"extra-data2"="value2"} Add a new user to LogicMonitor: New-LMUser -RoleNames @("administrator") -Password "changeme" -FirstName John -LastName Doe -Email jdoe@example.com -Username jdoe@example.com -ForcePasswordChange $true -Phone "5558675309" There are over ~150 cmdlets exposed as part of this module and more are being added each week as I receive feedback internally and from customers. For more details and other examples/code snippets or to contribute you can visit the github repo where this is hosted. Source Repository:https://github.com/stevevillardi/Logic.Monitor Additional Code Examples:https://github.com/stevevillardi/Logic.Monitor/blob/main/EXAMPLES.md Note: This is very much a personal project and not an official LogicMonitor integration. If the concept of a native PowerShell module interest you, I would recommend putting in a feedback request so that the demand can be tracked.
Can we grab Multiple time range data from the RESTAPI?
I’m working on another thread to report some predictive models and metrics to drive engineer response actions around volume growth/expansion. To do so, I’m calling the RESTAPI 10x per volume instance per device. (one datapoint value sample every 9 days back to 90). To do so, I’m building out a request for each of the day’s values (today - 9 days, today - 18 days, etc...). Is there a way to request multiple start/end values from the restAPI in a single request?Device DataSource Instance datapoint historical data using RestAPI v3
I am having problems getting the RestAPI to return any data regardless the combination of paths, query params, time filters I try using. What am I doing wrong? Here’s my ultimate URL I’ve built for this effort: $ddsiis a successfully retrieved object (DeviceDataSourceInstance) Start and End are from these: [int]$start = get-date (get-date).addMonths(-3) -uformat %s [int]$end = get-date (get-date).addMonths(-3).AddMinutes(5) -uformat %s /device/devices/$($ddsi.deviceid)/devicedatasources/$($ddsi.devicedatasourceid)/data?size=500&offset=0&start=$start&end=$end&datapoints=Capacity,PercentUsed All of the pieces and parts seem to line up with examples I’ve found here and in the LM Docs…it doesn’t error out, but returns nothing. Goal is to get volume capacity metrics from 3 months ago. Where am I going awry here? Everything works up until I add the /data at the end.
