Console Hardware Monitoring on ESXi

leave a comment »

Is there a command to check the “Health Status” on ESXi

/bin/cim-diagnostic.sh

This gives a console based CIM Hardware status. You can see more information in the VMWare Communities.

How to disable Plesk 9.5 Greylisting Filter with Postfix

with 2 comments

Due to the problems that Parallels seems to have to repair the Postfix Bugs since Version 9, deployed a year ago, the suffering clients need to get a workaround to their programming problems.

First it was the postfix-queue to deliver mail that had a bug related to antivirus and greylisting. Three upgrades later, version 9.3 the problem persists and the workaround was to disable the postfix proxy on master.cf.

Now they have online the version 9.5.2 and still the have the same problem. Our clients can not deliver mail. Our phones are boiling and Plesk does not seems to matter what happen to us. The new workaround is disabling the GreyListing Service in Plesk Postfix. To do that:

/usr/local/psa/bin/grey_listing --update-server -status off

This will disable the greylisting, will allow your customers to deliver mail and time to wait `til Parallels hire a good programming team to repair all the Postfix development for Plesk.

Sometimes you need to see what is happening in your VCenter Server. You could see the logs but it is a tedious task.

One of this secrets of the VCenter is that it comes with a Online Monitoring Web Interface that can be accessed via:

Linux “watch” command and VMWare Snapshot deletion

leave a comment »

Sometimes you have a really big snapshot that takes more than the 15 minutes Virtual Center gives to delete it.

In that cases after the timeout the snapshot continues being deleted on the Host Server.

So it is better to order the Remove Snapshot in the Host not in the Virtual Center because the Host hast no timeout.

Furthermore, here is a command to console of ESX to monitor the deletion process:

watch "ls -oghut --full-time *.vmdk"

or

watch "ls -lhut --time-style=full-iso *.vmdk

If you use ESXi you don’t have watch command available but you can do the ls command to see the process.
