What is SIEM? Security Information and Event Management solutions are a combination of the formerly disparate product categories of SIM (security information management) and SEM (security event management). SIEM technology provides real-time analysis of security alerts generated by network hardware and applications. The objective: To help companies respond to attacks faster and organize mountains of log data. Security Information and Event Management (SIEM) technologies take part in a crucial role in addressing the compliance, efficiency, and security needs of an enterprise. The central part of SIEM technologies is the ability to collect security data from all the critical assets on a network and present that data as actionable information via a single interface. SIEM solutions come as software, appliances, or managed services. Increasingly, SIEM solutions are being used to log security data and generate reports for compliance purposes. SIEM S...
Check and make sure that the process is actually stuck and not just taking a very long time. To do this, follow these steps: 1. Make sure SSH service is running on the ESXi host Navigate to configuration -> security profile -> services -> Click on Properties Choose the ‘SSH’ service, ‘Options’, and click ‘Start’ Once SSH is enabled, connect to the ESXi host using your favorite ssh client. 2. Run -> vim - cmd vmsvc / getallvms Find the vmid of the virtual machine, in this case its 20. 3. Now run -> vim - cmd vmsvc / get . tasklist 20 <- this is the # of the vm from above 4. Find the removeallsnapshots task # then run: vim - cmd vimsvc / task _ info 185720854 <- this # will be different for you If you see: “The object has already been deleted or has not been completely created” or similar, your snapshot removal is probably frozen, but in order to be sure, let’s loo...
After transferring and/or trying to restart a VM in ESX you may be presented with the error message “Unable to access a file since it is locked”. Now what you need to do is work out what is actually locking this file and then (unsurprisingly) find a way to unlock it. Generally the problem will be caused by one of three things. 1. Process Lock: There is a process on the ESX server that still has hold of a file(s) used by the VM. This is one of the most common causes. To resolve this there have been a couple of good VMware Forum postings here and here that have been consolidated to this useful posting over at GabesVirtualWorld.com (*Note: It is worth checking out the comment by Kent at the bottom of the posting). Also, check out Tecumseh’s posting here . 2. Disk Naming Conflict: Two or more disks with the same VMDK name. This can be caused by another disk with the same VMDK file name...
