Custom Threshold export

Question

Im trying to automate the export of all custom ("INSTANCE") alert thresholds from a specific LogicMonitor device group (org.org.devices) using PowerShell and the LogicMonitor REST API. I want to get a total count and optionally a breakdown per device.I have the following script which:Authenticates using the LMv1 HMAC schemeFinds the device group by its full pathRecursively retrieves all subgroups and devicesFetches datasources and instances for each deviceCounts thresholds where thresholdSource == 'INSTANCE'Runs in parallel across devices for performance&nbsp;param (
    [string]$AccessId,
    [string]$AccessKey,
    [string]$Company,
    [string]$GroupPath,
    [int]   $MaxThreads = 10
)

function Invoke-LmApi {
    param(
        [string]$Method,
        [string]$ResourcePath,
        [string]$QueryParams = '',
        [string]$Body = ''
    )
    $epoch = [math]::Round((Get-Date).ToUniversalTime() - [datetime]'1970-01-01').TotalMilliseconds
    $toSign = "$Method$epoch$Body$ResourcePath"
    $hmac = New-Object System.Security.Cryptography.HMACSHA256
    $hmac.Key = [Text.Encoding]::UTF8.GetBytes($AccessKey)
    $hash = $hmac.ComputeHash([Text.Encoding]::UTF8.GetBytes($toSign))
    $signature = [Convert]::ToBase64String($hash)
    $auth = "LMv1 ${AccessId}:${signature}:${epoch}"
    $url = "https://$Company.logicmonitor.com/santaba/rest$ResourcePath$QueryParams"
    return Invoke-RestMethod -Uri $url -Method $Method -Headers @{ Authorization = $auth }
}

function Get-GroupIdByPath {
    param([string]$Path)
    $resp = Invoke-LmApi -Method GET -ResourcePath '/device/groups' -QueryParams "?filter=fullPath:$Path&amp;size=1"
    if (-not $resp.data.items) { throw "Group '$Path' not found" }
    return $resp.data.items[0].id
}

function Count-CustomThresholds {
    param([string]$RootPath)
    $rootId = Get-GroupIdByPath -Path $RootPath
    $groupIds = @($rootId)
    # TODO: collect subgroups, devices and count thresholds in parallel
}

Count-CustomThresholds -RootPath "$Company/$GroupPath"However, I'm having trouble getting the script to reliably find my target group and export the counts. It either reports "Group not found" or hangs/slowly processes. Here is the current PowerShell script:What I've tried so far:Switching between filtering on name: vs fullPath:Adjusting group path prefixes (with/without company)Serial vs parallel loopsVerifying the group exists via manual API callsQuestions:What is the recommended way to filter by device group path (fullPath) using LogicMonitor's API?Are there any pitfalls in the LMv1 authentication or parallel Invoke-RestMethod calls I should avoid?How can I streamline this script to reliably export a summary of custom thresholds with minimal API calls?Any guidance would be greatly appreciated. Thanks in advance!

Hey Admine,For LM Powershell script interractions i strongly suggest using the Logicmonitor PS module - it has many benefits:&nbsp; https://logicmonitor.github.io/lm-powershell-module-docs/getting-started/For filtering data, i find it easier to pull everything from LM into a PS variable/table/hash/array/etc. and then filter afterwards.you could use something like this an an example:$filteredRootPaths = $RootPath | ForEach-Object {&nbsp; &nbsp; $_ | Where-Object { $_.name -like "&lt;custom threshold&gt;" }}$filteredRootPaths.CountHope i helped. Good luck.&nbsp;

It's been awhile since I've run this report but the Alert Thresholds report I think will accomplish the same thing minus some of the summarization.&nbsp;
