OneSight Administrator Guide

Updating Data Collectors and Remote Agents
The agent does not need to be removed prior to upgrading nor does
the machine need to be rebooted after upgrading. The agent is
stopped, its status is off-line, the update script updates the agent
with the new files, then restarts the agent.
Note: The update process may take several minutes. During the time
that the agent is stopped, no sampling occurs.
Agents must be running for the remote update to work. The
following agent types can be updated remotely:
Remote Agents – Agent Host Processes (AHP) only, and native
C/C++ agents.
Data Collectors – AHP and Java Host Process (JHP) together.
Remote agent update is not supported for agents with a version
prior to 4.7.465. The OneSight server version is displayed above the
table on the Agent Update screen. In addition, the Data Collector or
Remote Agent must have been installed with the auto-update option
turned on.
For UNIX, a signed gzipped tar file is sent from the server to the
agent:
Solaris - sunos_agent_update.tar.gz.sgn
Linux - linux_agent_update.tar.gz.sgn
If these files are not in the correct directory, the server may show
that it cannot update the Remote Agent.
If you are updating a VQ Probe, and the status on the Agent Update
page is, ― No update package available for this version of VQ
Probe,‖ you will need to run the
OneSightVQProbePackagesUpdater.exe file on the system where the
VQ Probe is installed. This file can be downloaded from eSupport.
Note that this program restarts the Hammer services.
