Backing Up and Recovering a Remote Collector Server
The vCenter Operations Manager remote collector is a remote host that has only the
vCenter Operations Manager collector installed. A remote collector does not store data. You might want to
install one or more remote collectors to navigate firewalls, reduce bandwidth across data centers, and reduce
the load on the vCenter Operations Manager server.
If a remote collector server becomes unavailable, the primary vCenter Operations Manager server does not
receive data from the portion of the monitored environment that is configured for that particular remote
collector.
Although you can install a remote collector on a cluster, typical implementations install a separate collector
on another server. This backup remote collector should have the same vCenter Operations Manager collector
adapters folder and the same vCenter Operations Manager collector configuration folder as the primary remote
collector. If the primary remote collector becomes unavailable, you can bring the backup remote collector
online.
Backing Up and Recovering a Remote DT Processor Server
A remote DT processor is a vCenter Operations Manager Server process that performs analytics calculations.
It does not store data. You can distribute the load by starting a separate analytics process on one or more remote
hosts to perform just the dynamic threshold (DT) portion of analytics processing.
If a remote processor server goes down, vCenter Operations Manager continues to collect and store data, but
dynamic thresholds are not recalculated based on the new data.
You do not need to have a backup of a remote DT processor. If the remote DT processor becomes unavailable,
you can configure the analytics process on the vCenter Operations Manager server to perform the dynamic
threshold calculations. See “Configure the Analytics Process to Perform DT Calculations,” on page 129.
You can also install the remote DT analytics process on a different host. See the VMware vCenter Operations
Installation Guide.
Configure the Analytics Process to Perform DT Calculations
If the remote DT processor becomes unavailable, you can configure the analytics process on the
vCenter Operations Manager server to perform dynamic threshold calculations.
IMPORTANT Always make a backup copy of the advanced.properties file. Changes that you make might cause
errors in the file that can adversely affect vCenter Operations Manager operations.
Prerequisites
Become familiar with how to start and stop the Analytics service. See “Start or StopvCenter Operations
Manager Services,” on page 102.
Procedure
1 Make a backup copy of the advanced.properties file in the vcenter-ops \user\conf\analytics directory
on the vCenter Operations Manager server.
2 Open the original advanced.properties file and find the distributedDTCalculationsEnabled property.
3 Change distributedDTCalculationsEnabled to false.
4 Save your changes and close the advanced.properties file.
5 Restart the Analytics service.
