Save and clear Eventlogs

Hello friends

This time i am posting "How to save and clear Eventlogs"

if most of your production servers are running on VM (virtualmachines) the space on OS drive (C) may reach above threshhold in that case you need to
clear some space.we can clear temp files and compress some logs.apart doing
all these we can create a powershellscript to save and clear eventlogs.


$applog=Get-WmiObject win32_nteventlogfile -Filter "logfilename = 'application'"
$date=Get-Date -Format ("dd-MM-yyy-mm-ss")
$applog.backupeventlog("d:\Applicationlog_$date.evtx")
$applog=Get-WmiObject win32_nteventlogfile -Filter "logfilename ='system'"
$applog.backupeventlog("d:\systemlog_$date.evtx")
Clear-EventLog -Log application,system

 

Resetting ILO's from Command Line

Last week i got a request from Application team to reboot few HP servers.

usually we use shutdown -i -r from run to reboot i have initiated the reboot and waited for more than  30 minutes but system is not coming up machine was in hung state. I tried to restart the machine using ILO. Unfortunately ILO is also not 
helping.then I seek one of my colleges help in resolving this issue and this is very good tip.

we can restart  machine using ILO commands.

use plink utility to login to the ILO.

HP Servers

Plink to the ILO ip with ID/Password.

 Plink 1.2.3.4 ( iloipaddress)

provide username and password

it will take you to the prompt :

</>hpiLO-> cd /map1
status=0
status_tag=COMMAND COMPLETED

</map1>hpiLO-> reset
status=0
status_tag=COMMAND COMPLETED
Resetting iLO. 

CLI session stopped.

You can even shutdown/restrat the server from here.

For more commands   type "help"

thanks to my brother AZAM

Getting Serial number for local system and Remote systems

Friends today i have posted a new article for getting serial number for local and remote systems

Well this is very helpful for System administrators who are maintaining the Inventory.

On local system

Getting service status on Local and remote servers

If you want to know the status of Particular service on local and Remote Servers use below Powershell cmdlets

On Local
PS C:\> Get-Service -Name spooler
Status   Name               DisplayName
------   ----               -----------
Running  spooler            Print Spooler
for remote servers

 PS C:\> Get-Service -Name spooler -ComputerName INDDC
Status   Name               DisplayName
------   ----               -----------
Running  spooler            Print Spooler

some time system admin need to disable or change the start up type of some important services on windows.If the windows Machines  are less than 10 we can manage but what will be if the count is more than 100?

Set-Service -Name "W32Time" -StartupType "disabled" -ComputerName (Get-Content C:\Computers.txt)

where computers.txt contains list of servers which we need to disable service..

It helps in saving lot of time..
