Logic.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.
Retrieving data from an external API via a Groovy Scripted module
1) Using Expert mode, define a resource as the hostname of the api in question, i.e. api.someapinamehere.com. For the purposes of this example, I'm going to make a call to worldtimeapi.org for data on the timezone America/Chicago to determine if daylight savings time is in effect. 2) Next, choose an available collector and group (optional) and click save. Note: normally you would also add your api user name (if any) and api token as properties, but in this case, it's not necessary. 2) Next, go to Settings -> LogicModules -> DataSources and click Add -> Datasource 3) Follow the steps below to adjust the DataSource: 4) Insert this script in the text box entitled Groovy Script under Collector Attributes import com.santaba.agent.groovyapi.expect.Expect; import com.santaba.agent.groovyapi.snmp.Snmp; import com.santaba.agent.groovyapi.http.*; import com.santaba.agent.groovyapi.jmx.*; import org.xbill.DNS.*; import groovy.json.*; //Defines host as the name of the resource added, in this case worldtimeapi.org def host = hostProps.get("system.hostname"); //Defines the path to endpoint def endpointUrl = "/api/timezone/America/Chicago" //Defines port. SSL would require 443. def port = 80 //Opens connection def httpClient = HTTP.open(host, port) //Get response def response = httpClient.get(endpointUrl) //Define status code def statusCode = httpClient.getStatusCode() //Close connection httpClient.close() //Extract values or handle error if(statusCode == 200){ response = new JsonSlurper().parseText(httpClient.getResponseBody()) if(response['dst'] == true){ status = 1 println("dstStatus=${status}") } else { status = 0 println("dstStatus=${status}") } } else { println("Your HTTP get request was not successful. StatusCode=${statusCode}") } 5) Add Normal datapoint named dstStatus 6) Save Module 7) You will see data painted in your portal for the device worldtimeapi.org under the name of the DataSource you created.

Hi All, I am trying to authenticate in servicenow using script but it is not working.

Hello, We have a need to via API, CLEAR an alert. I don’t see any API Methods to clear an alert. I only see methods to GET or POST a Note/ACK. Can you assist me with what API method we can use to clear (toggle on/off) an alert? Thanks, Darren Dudgeon
REST API 503 errors
Hello everyone We have been using various PowerShell scripts for years and have never had any problems with them. Now, since last week Monday, we are getting random 503 “server is busy” HTTP errors on some GET queries such as Devices, Device DataSources, Dashboards, etc. There is no recognizable pattern to the errors. Does this problem also occur for others using script automation via the REST API (occurs in V2 and V3)? I have submitted a support request to LM, but progress is slow... Have a nice day everyone Dorian
