Agent Communication
As of firmware version 1.3, your EnergySwitch PDU features Agent Communication functionality.
This enables the EnergySwitch to communicate to installed Agents on connected devices
(servers, etc.) and perform actions when set parameters and rules are met. The Agent will also
monitor the system it is installed on. In order to use the full capabilities of the functionality, 2
components need to be installed and configured correctly:
Agent Communication
Communication with the Agent service on connected servers.
UPS Integration
The link with the connected UPS in the rack (for more details see the UPS Integration
chapter).
When UPS Integration is not enabled, communication to connected Agents will be limited to
manual actions only.
Configuration
Setting up Agent Communication is a 2-step process:
1.
Installing and configuring the Agent service on the connected devices.
2.
Configuring the EnergySwitch to communicate to the installed Agent.
WARNING
: If both UPS Integration is enabled and Agent Communication is correctly configured
the EnergySwitch will perform automated actions according to strict pre-defined rules (based on
battery level, UPS status, etc.).
Please review these rules and actions carefully to avoid
unexpected behavior.
Agent Service
The Racktivity Agent service can be installed on both physical and virtual machines and is used to
monitor certain system parameters and to allow the EnergySwitch or the user to perform a
graceful shutdown or restart.
The system monitoring is performed at a 30 second interval and collapsed every 5 minutes.
The collapsed data can be retrieved from the Agent or sent to a predefined URL. This data will
allow the Racktivity DCPM platform to provide very detailed and accurate power consumption
down to application level.
The current version (v1.0) of the Agent service monitors the following:
Global CPU usage
Total number of processes
Top 10 processes according to CPU usage
Disks and their storage info: mount point, used bytes, available bytes
