Follow the optimal configuration strategies to collect all data from your VM
managers.
Pooling interval
Pooling interval is a period during which VM Manager tool is allowed to connect to all configured
VM managers, and collect and upload the data from these VM managers. If pooling interval
is exceeded, the VM Manager tool times out and the
next data collection cycle is delayed. If you want to count and report subcapacity, it
is necessary to capture mobility of virtual machines. Therefore, data from VM managers
must be collected every 30 minutes or more frequently. You can change the frequency of
data collection only if you use BigFix Inventory for
purposes other than subcapacity reporting. To specify the pooling interval, set the
value of the vmm_polling_time_interval parameter on the
Advanced Server Settings panel or in the configuration file
for VM Manager. For more information, see: Advanced server settings
and VM Manager Tool settings.
Number of virtual machines
The number of virtual machines that reside on VM
managers directly relates to the amount of data that needs to be gathered. If you configure multiple
connections from one VM Manager tool to VM managers that host
vast number of virtual machines, problems might occur. If it takes too long to collect data from all
configured connections, VM Manager tool times out as it
exceeds the pooling interval time. _BESClient_ArchiveManager_MaxArchiveSize
parameter limits the total size of files that are uploaded to the BigFix Inventory server. The limit might be exceeded by data that is
collected from all configured connections and as a result, the data is not uploaded. For more
information about the _BESClient_ArchiveManager_MaxArchiveSize parameter, see:
Configuring VM manager for subcapacity reporting
VM managers and network performance
Performance of VM Manager tool depends on the network typology of your environment as
well as the hardware specifications and the load of hypervisors. If network connection is slow or
the hypervisors take long time to respond and provide the requested data, performance of VM Manager tool can be significantly impacted.
