With the introduction of agent-based monitoring in OpManager MSP, users can now install a lightweight piece of software called an "agent" in their network devices such as Windows servers to aid OpManager MSP with monitoring your devices. The agent takes over all polling actions related to that device from OpManager MSP, allowing your OpManager MSP server to function more efficiently. For smooth functioning of OpManager MSP without load configuration changes, it is recommended that the agent be installed on not more than 1000 devices.
Agent monitoring feature in OpManager is available in build 127240 and above.
Before proceeding to install the agent and beginning to monitor your network devices, there are a few prerequisites that need to be addressed as follows:
These are the minimum specifications required in the device where the OpManager MSP agent will be installed:
Parameter | Minimum requirement |
Processor speed | 1.0 GHz |
RAM | 512 MB |
Hard disk space | 100 MB |
Supported OS versions:
The OpManager MSP agent supports all major versions of Microsoft Windows as listed below:
To ensure smooth functioning of Agent-based monitoring in OpManager MSP, the following ports need to be opened/available in the firewall, with respect to the device being monitored.
a. Agent-OpManager server communication
Port | Protocol | Direction | Description |
OpManager MSP probe webserver port* (https only) | TCP | Outbound | Used for communicating with the OpManager MSP probe server to transmit data. (8061 by default) |
b. Remote Agent deployment from UI(Deploy Agent)
For remote deployment, Ports 135 and 445 should be kept open and Inbound with respect to the monitored device. Initially, port 135 is used. RPC later switches it to any random port of TCP Dynamic port range. This dynamic port range must also be opened (Inbound).
NOTE:
To start using agent-based monitoring mode in OpManager MSP, SSL needs to be enabled to ensure secure communication.
Before beginning the installation process, make sure the OpManager MSP probe webclient is reachable from the end device that you are going to install the agent in.
If any Endpoint Management solutions have been employed in your network to manage your client computers, these applications need to be added in the exclusion list to ensure the OpManager MSP agent can run without any issues:
NOTE: To switch from agentless monitoring to agent-based mode for an existing device, follow these steps.
Note:
Before uninstalling OpManager MSP Probe, it is advisable to remove all the agents from your client computers. If you failed to do so and want to remove the agents after uninstalling OpManager MSP Probe, you can use either the Manual uninstallation method or the Bulk Uninstallation method to uninstall them from your client computers.
