Clear Exchange 2013 IIS Logs

Something I’ve been working on for a while is a script to clear up all those Exchange IIS logs which are generated through time.

Why are these logs not recycled after a period of time, well for good reason in most cases is to assist with troubleshooting when something goes wrong.

Anyhow, unlike logs such as the Exchange transport log these; which are recycled after they reach a certain size. The IIS logs don’t clear down automatically.

To help clear down disk space the following script can be used. Any IIS logs older than 30 days located in the “Exchange Back end” WWW will be purged.

Download this file save as ps1 and run as administrator on your Exchange servers. I have tested this on Exchange 2013 SP1 CU6 servers.

As always please test on non-production/test servers first to check that this will work with your own environment and have a solid backup of Exchange.

Start/Stop SSH access to VMWare ESXi using PowerCli

On occasion many VMware vSphere admins have to carry out a task on a ESXi host directly. Whether this is restarting the management agents, installing vibs or general administration. To do so remotely you need SSH and the ESXi shell services running.

For enhanced security the default action in ESXi 6 is for SSH and ESXi shell services to be disabled on startup.

Previously I went through the task of opening the vSphere client and enabling these manually each time. The following script provides a scripted method to stop and start these services for you. The script could be adapted to change other services and initiate secondary actions if required.

Prerequisite:

Install VMware vSphere PowerCLI, script has been tested with version 6 R1 available hereĀ vSphere PowerCLI 6.0 Release 1

All the variables are declared at the start of the script and prefixed with the dollar $ symbol.

Clone Virtual Machine in VMware with PowerCLI

Cloning a virtual machine can either be performed when powered on or off. I personally prefer to create a clone whilst the VM is offline to ensure that all data is in a consistent state.

Turning a VM off during the business day might not go down to well with your customers/users.

The following can be saved as a ps1 script and scheduled to run out of hrs in a maintenance window. If you specify the email setting in the script an email will be generated once completed to notify that the change has been completed.

Prerequisite:

All the variables are declared at the start of the script and prefixed with the dollar $ symbol.
