R&S®CHM System status monitoring software

Central management of system parameters of complex monitoring systems

Monitoring and communications systems include a large number of components that interact and mutually influence each other:

• Operating states (e.g. door contacts, temperature, humidity, smoke detectors, air pressure, fuel gauges, power supplies, servers, workstations)
• Storage media and databases (e.g. data volume of
  external and internal storage media, virtual memory
  capacity, database status information)
• Processor load (e.g. utilization of control computers,
  system servers, database servers)
• Network (e.g. accessibility of system components/
  IP addresses, load of network links)
• Status information about Rohde & Schwarz equipment (e.g. operating status of receivers, direction finders, demodulators or analyzers, BITE)
• Status information about system software
  (e.g. operating status of drivers and processes)

System-specific integrated monitoring appliances for monitoring relevant system components

A central server application – which can also be virtualized – manages all data from devices and subsystems that are accessible via LAN. Service personnel access Rohde & Schwarz devices via the appropriate device drivers.
Third-party devices can be accessed using standardized SNMP interfaces.
R&S^®CHM compares the incoming data against predefined thresholds. If a measured value exceeds or falls below this threshold, the user receives a notification on the user interface or the Windows system tray.

Display of measured values versus time

R&S^®CHM offers detailed views for hardware components
such as PCs. When selecting a component, the associated
detailed view is shown.
Measured values such as temperature profiles or used
memory/hard drive space are displayed in a constellation
diagram.

Quick overview of current system status

The console application available on every workstation shows all relevant information in a clear graphical and text format.
In the event of an error message, the operator is immediately transferred to the dedicated device/management interface, permitting quick and in-depth error analysis and
troubleshooting.

Easy system setup

Depending on the overall system setup and requirements, R&S^®CHM can be installed as a virtual server or as a separate hardware server. The dedicated hardware installation is significantly more robust and offers independent system shutdown and restart.
Configuration is equally simple and flexible for both models. During the system  integration, the information required for R&S^®CHM is extracted from the system
configuration tool and saved as a file. This system configuration file is read into the R&S®CHM server via the management GUI. System software updates are applied in the same way.
The software also supports hierarchical system configurations, so that distributed systems with unattended remote stations, for example, can be monitored effectively.
If errors occur, the configuration can simply be reloaded from the original configuration file. This significantly reduces downtimes.

Extensive hardware support

Radiomonitoring systems from Rohde & Schwarz typically
consist of a number of different devices, some of which
may also be supplied by third-party providers. In addition to Rohde & Schwarz devices, R&S^®CHM supports many third-party system devices, including:

• Uninterruptible power supplies (UPS)
• Power distribution units (PDU)
• A wide variety of IT hardware (servers and workstations)
• Network devices, including routers, switches and time servers
• Devices with standardized SNMP interface

User-friendly, straightforward user interface

R&S®CHM
offers different result displays. An icon on the Windows system tray provides an initial basic indication of the system status. The main window of the console application offers a more detailed overview. The operator has a complete overview of the individual subsystems and their components. This is particularly useful for distributed systems with unattended, remotely controlled stations.
The data can be called up in a web browser with restricted functionality. This makes it possible to check the system status away from the operator workstation.

Basic system control and emergency management

R&S®CHM enables the centralized startup and shutdown of radiomonitoring systems in both regular and irregular principal scenarios. The operator initiates regular system startup and shut down via the central menu item on the R&S®CHM operator console. The irregular scenario is when the failure of a single system component affects or stops a subsystem or the entire system from functioning. This is seen in particular with system-critical parameter changes, for example if critical hardware or ambient temperatures are reached after the  failure of air conditioners that cool system components. In such cases, R&S®CHM can perform an emergency shutdown. The shutdown disconnects all critical components – such as the database server – from the network to prevent damage.
