  • 0

I am rolling my own simple web-based perfmon, I am not happy with some of the data I can get like cpu usage, which i use via a sql query. I am able to get memory usage just fine…I will attach a screenshot, so you can see what I currently have for my main/home/dashboard page.

I am currently using webcharts3d, which i am loving being able to use ajax, update the chart, and i have a dynamically updating dashboard. Yes of course I have to get only a few performance counter’s so in my desire to have a web-based performance dashboard i do not kill the server.

DECLARE @CPU_BUSY int, @IDLE int
SELECT @CPU_BUSY = @@CPU_BUSY, @IDLE = @@IDLE WAITFOR DELAY '000:00:01'
SELECT  (@@CPU_BUSY - @CPU_BUSY)/((@@IDLE - @IDLE + @@CPU_BUSY - @CPU_BUSY) *1.00) *100 AS 'CPU'

And all i get in results is 0.0000, so either the query is wrong, or i have very little cpu activity going on. Where as when I use my windows task manager.

Here is the code for gathering memory I am using, I do not claim credit for any of this code, I found it somewhere.

<cfscript>
      jRuntime = CreateObject("java","java.lang.Runtime").getRuntime();
      memory = StructNew();
      memory.freeAllocated = jRuntime.freeMemory() / 1024^2;
      memory.allocated = jRuntime.totalMemory() / 1024^2;
      memory.used = memory.allocated - memory.freeAllocated;
      memory.percentUsedAllo = (memory.used / memory.allocated) * 100;
</cfscript>

So I am looking for more wmi or java or scripts to get cpu usage, and perhaps any other important server stat.

    How about using Coldfusion built-in function called, GetMetricData. It can help you to monitor your server performance like Coldfusion Admin. I’ve done it with bar of cfchart. If you wanna integrate with Web3Dcharts, you can.

    http://ppshein.wordpress.com/2010/08/04/getmetricdata-for-server-monitor/

    <cfset pmData = GetMetricData(“PERF_MONITOR”) >
<cfchart chartheight=”500″ chartwidth=”700″ format=”PNG” showlegend=”yes”>
    <cfchartseries type=”bar” seriescolor=”##639526″ paintstyle=”light” colorlist=”##ff8080,##ffff80,##80ff80,##0080ff,##ff80c0,##ff80ff,##ff8040,##008000,##0080c0,##808000″>
        <cfchartdata item=”Page Hits” value=”#pmData.PageHits#”>
        <cfchartdata item=”Request Queued” value=”#pmData.ReqQueued#”>
        <cfchartdata item=”Database Hits” value=”#pmData.DBHits#”>
        <cfchartdata item=”Request Running” value=”#pmData.ReqRunning#”>
        <cfchartdata item=”Request TimedOut” value=”#pmData.ReqTimedOut#”>
        <cfchartdata item=”Bytes In” value=”#pmData.BytesIn#”>
        <cfchartdata item=”Bytes Out” value=”#pmData.BytesOut#”>
        <cfchartdata item=”Avg Queue Time” value=”#pmData.AvgQueueTime#”>
        <cfchartdata item=”Avg Request Time” value=”#pmData.AvgReqTime#”>
        <cfchartdata item=”Avg Database Time” value=”#pmData.AvgDBTime#”>
    </cfchartseries>
</cfchart>
