Back in December i replaced my Certificate on my VMWare Appliance with a our new Wildcard certificate.
But here in January, i got an alarm saying “Certificate Alarm” and it trigger it as an Alert.

Searching around for a solution, on what certificate that expire soon, i found this command:

for i in $(/usr/lib/vmware-vmafd/bin/vecs-cli store list); do echo STORE $i; /usr/lib/vmware-vmafd/bin/vecs-cli entry list --store $i --text | egrep "Alias|Not After"; done

It showing me that a backup mackine certificate is expiring

So i exported this Machine certificate to a CRT file, and then deleted it with these commands

mkdir /certificates

/usr/lib/vmware-vmafd/bin/vecs-cli entry getcert --store BACKUP_STORE --alias bkp___MACHINE_CERT --output /certificates/old_machine.crt

/usr/lib/vmware-vmafd/bin/vecs-cli entry delete --store BACKUP_STORE --alias bkp___MACHINE_CERT -y

It then tell me that the certificate have been deleted

Deleted entry with alias [bkp___MACHINE_CERT] in store [BACKUP_STORE] successfully

Also running this command again

for i in $(/usr/lib/vmware-vmafd/bin/vecs-cli store list); do echo STORE $i; /usr/lib/vmware-vmafd/bin/vecs-cli entry list --store $i --text | egrep "Alias|Not After"; done

Show that the certificate have now gone.
