rsp (Remote System Probe)

The Remote System Probe (rsp) allows you agentless retrieval of performance data of a system. The probe can be installed on the remote hub to remotely monitor the performance of the following system parameters:

The Remote System Probe (rsp) allows you agentless retrieval of performance data of a system. The probe can be installed on the remote hub to remotely monitor the performance of the following system parameters: 
  • CPU
  • Disk
  • Memory
  • Load
  • NTEvents
  • Processes
  • Services
  • WMI objects
What does the probe monitor?
The probe gathers statistics on the CPU utilization, disk, memory usage, and load along with processes, services, WMI events, with minimal increase in resource utilization of the monitored system. For more information on these statistics, see rsp Metrics.
These statistics help you to monitor:
  • current system performance
  • system performance trend over time
  • proactive resource planning based on historical trends
  • avoid system downtime
  • performance tuning based on the QoS parameters
The probe monitors thresholds for all the retrieved data points and also allows you to retrieve the QoS data. The QoS names match with the cdm probe as the monitored data is the same.
How does the probe collect data?
To retrieve remote data, the probe uses:
  • WMI on Windows systems, using port 135
  • Commands on UNIX/Linux systems on SSH, using port 22
The probe supports only password-based and key based authentication. Keyboard-Interactive and authentication less method are not supported. If the unix-based remote server is not password-based or key-based authentication that is enabled, the rsp probe is unable to discover the remote host.
How does the probe display data on USM?
The probe does not automatically discover any host(s) for monitoring. You need to specify administrator credentials to connect to the monitored hosts, and then add the hosts in the probe it can discover and connect to the host. After a successful connection, configure the probe to enable data retrieval and monitoring.
The following diagram shows how the probe connects to the host and displays its performance data on the Unified Service Management (USM):

Probe Architecture
  1. The probe connects to the host using administrator credentials.
  2. After a successful connection, you can enable the profile for monitoring.
  3. You must define the QoS and thresholds to retrieve performance data of the monitored host.
  4. The probe monitors the defined thresholds and QoS for the activated monitors.
  5. The probe stores this data in the database through the Discovery Server.
  6. The USM gathers performance data from the database to display it.
