Products

• VMware vCenter Server

Issue/Introduction

• This KB provides the steps to find the Timestamps of the Hosts that are added/removed to or  from the vCenter

Environment

• VMware vCenter Server 6.x
• VMware vCenter Server 7.x
• VMware vCenter Server 8.x

Resolution

1. SSH into the vCenter 
2. Go to the vpxd directory
   
   

   cd /var/log/vmware/vpxd/

3. Look for the keywords 'Add_host' and 'Remove_host'
   
   

   [ /var/log/vmware/vpxd ]# less vpxd.log | grep -i 'Add_host'
   [ /var/log/vmware/vpxd ]# less vpxd.log | grep -i 'Remove_host'

   The sample output will look similar to the example below: 
   
   

   [ /var/log/vmware/vpxd ]# less vpxd.log | grep -i 'Add_host'
   ####-##-##T##:##:##.###Z info vpxd[######] [Originator@6876 sub=MoCluster opID=######] Dispatching cluster store membership request; {######, ADD_HOST, domain-c#, [vim.HostSystem:host-#,example.com], attempt: 1}
   ####-##-##T##:##:##.###Z info vpxd[######] [Originator@6876 sub=MoCluster opID=###### req=######] Cluster store membership request completed; {######, ADD_HOST, domain-c#, [vim.HostSystem:host-#,example.com], attempt: 1}, e: (null)
    
   [ /var/log/vmware/vpxd ]# less vpxd.log | grep -i 'Remove_host'
   ####-##-##T##:##:##.###Z info vpxd[######] [Originator@6876 sub=MoCluster opID=######] Dispatching cluster store membership request; {######, REMOVE_HOST, domain-c#, [vim.HostSystem:host-#,example.com], attempt: 1}
   ####-##-##T##:##:##.###Z info vpxd[######] [Originator@6876 sub=MoCluster opID=###### req=######] Cluster store membership request completed; {######, REMOVE_HOST, domain-c#, [vim.HostSystem:host-#,example.com], attempt: 1}, e: (null)

   Note:example.com is the name (FQDN) of the ESXI Host that has been added and removed from the vCenter in the above output
