Writing PowerCLI for Performance

Writing PowerCLI for Performance

I was building a piece of PowerCLU code to check on my vCD Deployed vAPPs for certain errors and because it’s me I was curious what performance difference there was between using array based operations verses piped operations in powershell. Here’s what I found out. Here is the array based operation – time to completion 2 minutes 30 seconds. $myVAPP = @(Get-CIVApp | Select-Object Org, Name, Status)        foreach ($myVAPP.Name in $myVAPP)            {                IF ($myVAPP.Status -eq “FailedCreation”)                     {                        Write-Host ‘vAPP’…

vFabric Hyperic Server Heartbeat

I wrote a quick safety feature for my Hyperic server that monitors the Hyperic Server process every minute and if the Server stops or dies the script will attempt to restart it.

To do this go to Administration > Escalation Schemes Configuration. Next Let’s go ahead and build the process of…

Agentless / Network Monitoring with Hyperic

So… I’ve installed Hyperic and am using it to monitor a bunch of stuff (Disk Space, RAM, CPU, Services) on boxes that I have installed the Hyperic Agent on but I really want to just do a simple ping against a bunch of network devices for network monitoring…. Looking at the UI it is not at all obvious how I would accomplish such a task. The answer is you have to run the job against an agent, and here’s how…

Using VMware vCenter Operations Manager

Using VMware vCenter Operations Manager

As part of my day to day routine this morning I ran into a quick use case that offers a perfect introduction to VMware vCOPS and what it can do for your environment to help detect issues before they become issues as well as finding the root causes of performance problems. If you have never seen vCOPS before here is a funny video that pretty much explains what the product is all about: http://www.youtube.com/watch?v=mwYjwrE81eg This example is a real life…
