Overview:

Power Automate holds it own set of logs and history. While Power Automate's internal logging is good and useful, it does not push logs into App Insights or Log Analytics for central monitoring.
You can manually export Power Automate logs from Power Platform and import them into Log Analytics, using the "Data Export" option.

You can use the built in action to log directly to Azure Log Analytics with a flow. Here is a 4 min recording outlining the approach in a Power Automate Flow.

Or you can create an Azure Functions that you can use to write to App Insights, below is a simple recording of the function (this is recording aims to remove complexity so there is no VS Code or publishing.

Function to write into App Insights Logs

#r "Newtonsoft.Json"
using System.Net;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Primitives;
using Newtonsoft.Json;
public static async Task<IActionResult> Run(HttpRequest req, ILogger log)
{
    string requestBody = await new StreamReader(req.Body).ReadToEndAsync();
    dynamic data = JsonConvert.DeserializeObject(requestBody);
    int eventId = data?.eventId;
    string errType = data?.errType;
    string errMsg = data?.errMsg;
    string correlationId = data?.correlationId;
    string workflowId = data?.workflowId;
    string workflowUrl = data?.workflowUrl;
    string flowDisplayName = data?.flowDisplayName;

var custProps = new Dictionary<string, object>()
{
    { "CorrelationId", correlationId},
    { "WorkflowId", workflowId},
    { "WorkflowUrl", workflowUrl},
    { "WorkflowDisplayName", flowDisplayName}
};

using (log.BeginScope(custProps))
{
    if (errType=="Debug")
    {
        log.Log(LogLevel.Debug, eventId, $"{errMsg}");
    }
    else if (errType=="Critical")
    {
        log.Log(LogLevel.Critical, eventId, $"{errMsg}");
    }
    else if (errType=="Warning")
    {
        log.Log(LogLevel.Warning, eventId, $"{errMsg}");
    }
    else if (errType=="Trace")
    {
        log.Log(LogLevel.Trace, eventId, $"{errMsg}");
    }
    else if (errType=="Error")
    {
        log.Log(LogLevel.Error, eventId, $"{errMsg}");
    }
    else
    {
      log.LogInformation($"Event is {eventId}, type is {errType}, and msg is {errMsg}");
    }
};
    string responseMessage = $"This HTTP triggered function executed successfully. {errType} - {errMsg}";
    return new OkObjectResult(responseMessage);
}

There is nice analytics inside the Power platform Admin Centre as shown below to examine Flows/Power automate:
