Citrix Systems 6 manual Pool-retrieve-wlb-diagnostics, Host-retrieve-wlb-evacuate-recommendations

pool-retrieve-wlb-diagnostics

Use the pool-retrieve-wlb-diagnosticscommand to return the full contents of the Workload Balancing Log file for the Workload Balancing server that the pool is currently using. This command also returns some version information.

xe pool-retrieve-wlb-diagnostics \

host-retrieve-wlb-evacuate-recommendations

host-retrieve-wlb-evacuate-recommendations uuid=<host_uuid>

Returns the evacuation recommendations for a host, and a reference to the UUID of the recommendations object.

vm-retrieve-wlb-recommendations

Returns the workload balancing recommendations for the selected VM. The simplest way to select the VM on which the operation is to be performed is by supplying the argument vm=<name_or_uuid>. VMs can also be specified by filtering the full list of VMs on the values of fields. For example, specifying power-state=haltedselects all VMs whose power-state is halted. Where multiple VMs are matching, specify the option --multipleto perform the operation. The full list of fields that can be matched can be obtained by the command xe vm-list params=all. If no parameters to select VMs are given, the operation will be performed on all VMs.

pool-certificate-list

XenServer Workload Balancing component lets you use certificates to secure communication between XenServer pools and the Workload Balancing server. You can either use the default test certificate, which is created automatically during Workload Balancing configuration, or you can specify a certificate from a Trusted Authority.

To use a Trusted Authority certificate, the certificate must be in X.509 format and comply with the guidelines provided earlier in the Workload Balancing Administrator's Guide. If you want to verify the presence of a certificate from a Trusted Authority, you must:

pool-certificate-list

Lists all installed SSL certificates.

pool-certificate-install

pool-certificate-install filename=<certificatefilename>

Run this command on the pool to install the certificate on the Workload Balancing virtual appliance on the pool master.

pool-certificate-sync

pool-certificate-sync

Run this command on the pool, after running the pool-certificate-install command, to make sure the certificate and certificate revocation lists are synchronized from the pool master to all slaves on the pool.

pool-param-set

pool-param-setwlb-verify-cert=<true>uuid=<uuid_of_pool>

Run this command on the pool, after running the pool-certificate-sync command, to make XenServer always verify the certificate when communicating with the Workload Balancing server.

Tip:

Pressing the Tab key automatically populates the UUID of the pool.
