Issues with Set-LMWebsiteGroup
I'm working with the lm-powershell-module and I'm able to get all my website information and the groups id's but when I try to update the group information so I can bulk move websites nothing seems to happen. I have tried many different ways such as: Set-LMWebsiteGroup -Name 'CNVPABACUSS252/Servicing/Loan' -ParentGroupName 'Production/Internal/DevOps/Individual Nodes/Abacus Sync' Set-LMWebsiteGroup -Name $website.name -ParentGroupName 'Production/Internal/DevOps/Individual Nodes/Abacus Sync' -ParentGroupId 77 Set-LMWebsiteGroup -Id 3526 -ParentGroupId 77 I'm sure my syntax is not correct somewhere, but I'm drawing a blank on what it is. Thanks for your help.
NOC Rollup Status Dashboards for MSPs
LM doesn't come with it out of the box, so I built the NOC Dashboard I've wanted. It provides high level, at-a-glance health indicators for each of our client environments we manage. This makes a great "big board" for a NOC room or a second screen status board for work from home NOC/Support folks. I do have three examples in this code for ways to filter for specific teams/purposes. This all collapses for ease of reference correctly in Powershell ISE on windows. Line 282 references a dataSource I wrote that counts frequency of specific eventlog events to illustrate potential brute force attempts (CTM are my initials, we tag our scripts to make finding the best source of answers faster in the future - old habit from pen & paper change logs from a previous job). As any screenshots would contain client names, I'm unable to post any screen shots of the results of this, but my current settings for my Main dashboard are (This is the first Dashboard I've made that looks better in UIv4 than 3): ... #!!! These two need to be changed. First is a string, second an integer #!!! See the comment block below for instructions # The first chunk of your company's logicmonitor URL $company = "yourCompanyNameHere" # ID of the group to be used as a source for the NOC widget items $parentGroupID = <parentGroupID> <# Netgain Technology, llc ( https://netgaincloud.com ) 2/26/2024 - Developed by Cole McDonald Disclaimer: Neither Netgain nor Cole McDonald are not responsible for any unexpected results this script may cause in your environment. To deploy this: - COLLECTOR: you will need a collector for scripting, this will be the single applies to target. You may need to increase the script timeout depending on the size of your device deployment. - DASHBOARD: you will need a Dashboard with a NOC widget on it. The name can be whatever you'd like, there will be a name change in the "name" property for the initial array. In the case of the first example here, "NOC - Master" - PARENT GROUP: you will need to identify the ID# of the group you wish to use as the source for the subgroup list and set the $parentGroupID to the appropriate ID# Purpose: Create an auto-updating high level NOC dashboard that can show - Rollup state for a list of client subgroups from our \Clients group - Group Indicators for a specific dataSource - Group indicators for a subset of devices within each group After the API region, there are three separate dashboards referenced to illustrate the 3 methods for using this dataSource. NOTE: my code uses backticks for line continuation. Where possible in my code, each line indicates a single piece of information about the script's algorithm and the first character in each line from a block indicates the line's relationship to the one above it. #> #region Rest API Initialization and Functions # Init variables used in the RESTApi functions $URLBase = "https://$company.logicmonitor.com/santaba/rest" $accessID = "##ApiAccessID.key##" $accessKey = "##ApiAccessKey.key##" #-------- The Functions ---------- function Send-Request { param ( $cred , $URL , $accessid = $null, $accesskey = $null, $data = $null, $version = '3' , $httpVerb = "GET" ) if ( $accessId -eq $null) { exit 1 } <# Use TLS 1.2 #> [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12 <# Get current time in milliseconds #> $epoch = [Math]::Round( ( New-TimeSpan ` -start (Get-Date -Date "1/1/1970") ` -end (Get-Date).ToUniversalTime()).TotalMilliseconds ) <# Concatenate Request Details #> $requestVars = $httpVerb + $epoch + $data + $resourcePath <# Construct Signature #> $hmac = New-Object System.Security.Cryptography.HMACSHA256 $hmac.Key = [Text.Encoding]::UTF8.GetBytes( $accessKey ) $signatureBytes = $hmac.ComputeHash( [Text.Encoding]::UTF8.GetBytes( $requestVars ) ) $signatureHex = [System.BitConverter]::ToString( $signatureBytes ) -replace '-' $signature = [System.Convert]::ToBase64String( [System.Text.Encoding]::UTF8.GetBytes( $signatureHex.ToLower() ) ) <# Construct Headers #> $auth = 'LMv1 ' + $accessId + ':' + $signature + ':' + $epoch $headers = New-Object "System.Collections.Generic.Dictionary[[String],[String]]" $headers.Add( "Authorization", $auth ) $headers.Add( "Content-Type" , 'application/json' ) # uses version 2 of the API $headers.Add( "X-version" , $version ) <# Make Request #> $response = Invoke-RestMethod ` -Uri $URL ` -Method $httpVerb ` -Body $data ` -Header $headers ` -erroraction SilentlyContinue ` -warningaction SilentlyContinue Return $response } function Get-LMRestAPIObjectListing { param ( $URLBase , $resourcePathRoot , # "/device/devices" $size = 1000 , $accessKey , $accessId , $version = '2' ) $output = @() $looping = $true $counter = 0 while ($looping) { #re-calc offset based on iteration $offset = $counter * $size $resourcePath = $resourcePathRoot $queryParam = "?size=$size&offset=$offset" $url = $URLBase + $resourcePath + $queryParam # Make Request $response = Send-Request ` -accesskey $accessKey ` -accessid $accessId ` -URL $url ` -version $version if ( $response.items.count -eq $size ) { # Return set is full, more items to retrieve $output += $response.items $counter++ } elseif ( $response.items.count -gt 0 ) { # Return set is not full, store date, end loop $output += $response.items $looping = $false } else { # Return set is empty, no data to store, end loop $looping = $false } } write-output $output } # Get Dashboards $resourcePath = "/dashboard/dashboards" $dashboards = Get-LMRestAPIObjectListing ` -resourcePathRoot $resourcePath ` -accessKey $accessKey ` -accessId $accessID ` -URLBase $URLBase # Get Widgets $resourcePath = "/dashboard/widgets" $widgets = Get-LMRestAPIObjectListing ` -resourcePathRoot $resourcePath ` -accessKey $accessKey ` -accessId $accessID ` -URLBase $URLBase # Get Groups $resourcePath = "/device/groups" $Groups = Get-LMRestAPIObjectListing ` -resourcePathRoot $resourcePath ` -accessKey $accessKey ` -accessId $accessID ` -URLBase $URLBase #endregion function generateJSON { param( $dashInfo, $clientnames, $deviceDisplayName = "*", $DSDisplayName = "*" ) $itemArray = @() foreach ($name in $clientnames) { $itemArray += @{ "type" = "device" "deviceGroupFullPath" = "Clients/$name" "deviceDisplayName" = $deviceDisplayName "dataSourceDisplayName" = $DSDisplayName "instanceName" = "*" "dataPointName" = "*" "groupBy" = "deviceGroup" "name" = "`#`#RESOURCEGROUP`#`#" } } # Write JSON back to the API for that widget $outputJSON = "`n`t{`n`t`t`"items`" : [`n" foreach ($item in $itemArray) { $elementJSON = @" { `"type`" : `"$($item.type)`", `"dataPointName`" : `"$($item.dataPointName)`", `"instanceName`" : `"$($item.instanceName)`", `"name`" : `"$($item.name)`", `"dataSourceDisplayName`" : `"$($item.dataSourceDisplayName)`", `"groupBy`" : `"$($item.groupBy)`", `"deviceGroupFullPath`" : `"$($item.deviceGroupFullPath)`", `"deviceDisplayName`" : `"$($item.deviceDisplayName)`" } "@ if ($item -ne $itemArray[-1]) { $outputJSON += "$elementJSON,`n" } else { # Last Item $outputJSON += "$elementJSON`n`t`t]`n`t}" } } write-output $outputJSON } # Get Client Names from groups $clientnames = ( $groups ` | where parentid -eq $parentGroupID ` | where name -notmatch "^\." ).name | sort #ID Master Dashboard # declare dashboard name and set default id and widgetid to use in the loop later $masterDash = @{ id=0; widgetid=0; name="NOC - Master" } $master = $dashboards | ?

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 data
Example script for automated alert actions via External Alerting
Below is a PowerShell script that's a handy starting point if you want to trigger actions based on specific alert types. In a nutshell, it takes a number of parameters from each alertand has a section of if/elsestatements where you can specify what to do based on the alert.It leverages LogicMonitor'sExternal Alertingfeature so the script runs local to whatever Collector(s)you configure it on. I included a couple of example actions forpinging a device and forrestarting a service.It also includes some handy (optional) functions for logging as well as attaching a noteto thealert in LogicMonitor. NOTE: this script is provided as-is and you will need to customize it to suit your needs. Automated actions are something that must be approached with careful planning and caution!! LogicMonitor cannot be responsible for inadvertent consequences of using thisscript. If you want try it out, here's how to get started: Update the variables in the appropriate section near the top of the script with optional API credentialsand/or log settings. Also change any of the if/elseif statements (starting around line #95) to suit your needs. Save the script onto your Collector server.I named the file"alert_central.ps1" but feel free to call it something else. Make note of it’s full path (ex: “C:\scripts\alert_central.ps1”). NOTE: it’s notrecommended to place it under the Collector's agent/lib directory (typically "C:\Program Files (x86)\LogicMonitor\Agent\lib") since that location can be overwritten by collector upgrades. In your LogicMonitor portal go to Settings, then External Alerting. Click the Add button. Set the 'Groups' field as needed to limit the actions to alerts from any appropriategroup of resources. (Be sure the group's devices would be reachable from the Collector running the script) Choose the appropriate Collector in the Collectorfield. Set Delivery Mechanismto "Script" Enter the name you saved the scriptas (in step #2)in theScriptfield (ex. "alert_central.ps1"). Paste the following into the Script Command Linefield (NOTE: if you add other parameters here then be sure to also add them to the 'Param' line at the top of the script): "##ALERTID##" "##ALERTSTATUS##" "##LEVEL##" "##HOSTNAME##""##SYSTEM.SYSNAME##" "##DSNAME##" "##INSTANCE##" "##DATAPOINT##" "##VALUE##" "##ALERTDETAILURL##" "##DPDESCRIPTION##" Example of the completed Add External Alerting dialog Click Save. This uses LogicMonitor's External Alerting featureso there are some things to be aware of: Since the script is called foreveryalert, the section of if/then statements at the bottom of the script is important for filtering what specific alerts you want to take action on. The Collector(s) oversee the running of thescript, so be conscience to any additional overhead the script actions may cause. It could take up to 60 seconds for the script to trigger from the time the alert comes in. This example is a PowerShell script so best suited for Windows-based collectors, but could certainly be re-written as a shell script for Linux-based collectors. Here's a screenshot of acleared alert where the script auto-restarted a Windows service and attached a note based on its actions. Example note the script added to the alert reflecting the automated action that was taken Below is the PowerShell script: # ---- # This PowerShell script can be used as a starting template for enabling # automated remediation for alerts coming from LogicMonitor. # In LogicMonitor, you can use the External Alerting feature to pass all alerts # (or for a specific group of resources) to this script. # ---- # To use this script: # 1. Update the variables in the appropriate section below with optional API and log settings. # 2. Drop this script onto your Collector server under the Collector's agent/lib directory. # 3. In your LogicMonitor portal go to Settings, then click External Alerting. # 4. Click the Add button. # 5. Set the 'Groups' field as needed to limit the actions to a specific group of resources. # 6. Choose the appropriate Collector in the 'Collector' field. # 7. Set 'Delivery Mechanism' to "Script" # 8. Enter "alert_central.ps1" in the 'Script' field. # 9. Paste the following into the 'Script Command Line' field: # "##ALERTID##" "##ALERTSTATUS##" "##LEVEL##" "##HOSTNAME##" "##SYSTEM.SYSNAME##" "##DSNAME##" "##INSTANCE##" "##DATAPOINT##" "##VALUE##" "##ALERTDETAILURL##" "##DPDESCRIPTION##" # 10. Click Save. # The following line captures alert information passed from LogicMonitor (defined in step #9 above)...

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 $true -Phone "5558675309" There are over ~150 cmdlets exposed as part of this module and more are being added each week as I receive feedback internally and from customers. For more details and other examples/code snippets or to contribute you can visit the github repo where this is hosted. Source Repository:https://github.com/stevevillardi/Logic.Monitor Additional Code Examples:https://github.com/stevevillardi/Logic.Monitor/blob/main/EXAMPLES.md Note: This is very much a personal project and not an official LogicMonitor integration. If the concept of a native PowerShell module interest you, I would recommend putting in a feedback request so that the demand can be tracked.
Finding the culprit for TCP_StatsCollector ConnectionsEstablished alert for Windows collectors
From the collector’s device page in the LM Portal or the collectors page, get to a debug console, then here’s your !POSH one-liner to get info about the destination device that is holding your ports captive. netstat -an| sls establish | foreach { ($_ -split "\s+")[3] } | group | sort count | select count, name -last 10 In the Netstat, a shows all, n shows IP addresses rather than solving the DNS for it. TheSelect-String (aliased as sls)passes only the “Established” connection entries from the netstat down the pipeline. The foreach{} splits each line ($_ is the current object being iterated by the foreach loop) on contiguous whitespace (I use this a lot!) and takes the third element (remote address:port) to passdown the pipeline It then passes Group-Object (aliased as group) which bundles identical strings and Sort-Object (aliased as sort)by the count property of the group object. The select displays grabs the calculated match count and the name properties to limit display and just shows the -last 10 of them (which are the biggest number of matched lines due to the sort previously applied. This should give you the target/s for troubleshooting further.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?
