OpsRamp supports Agentless monitoring in addition to regular gateway-based monitoring (ICMP, SNMP, and VMware). Agentless monitors use the gateway to monitor the remote resources and to track the health and performance of the network, storage, virtual resources, and Platform as a Service (PaaS) cloud resources.
The following Ports and Protocols are used for monitoring on the remote resource.
|WSMan (WBEM WS-Management)||5985||TCP|
Supported protocols and gateway types
For Agentless custom monitors, the gateway connects to a remote device. The table below describes the possible combinations of supported protocols and gateway types.
|Gateway Type||Remote Linux Resource||Remote Windows Resource|
|Classic Gateway (Linux)||Possible - SSH-based discovery||RSE - Shell script based monitor is supported||Not possible||Not possible|
|Classic Gateway (Linux)||RSE - Python script based monitor is supported|
|Classic Gateway (Linux)||RSE - PowerShell based monitor is not supported|
|Windows Gateway||Possible - SSH-based discovery||RSE - Shell script based monitor is supported||Possible - WMI-based discovery||RSE - Shell script based monitor is not supported|
|Windows Gateway||RSE - Python script based monitor is supported||RSE - Python script based monitor is supported|
|Windows Gateway||RSE - PowerShell based monitor is not supported||RSE - PowerShell based monitor is supported|
After connecting to the remote device, the gateway collects data and displays it as graphs or notifications based on the threshold.
