(This cache is internal to the server and unrelated to L1/L2 system memory cache.) Because these operations occur faster with less resource contention than non-cached memory functions, a higher percentage indicates greater server efficiency. The difference represents memory that the server has reserved for use, but that is currently idle.Ĭache_Hit_Ratio- This monitor returns the percentage of memory operations during this RSS period that were carried out using the server's memory cache. This may be less than the amount of application memory reported by the operating system. Used - This monitor returns the amount of memory, in units defined by a script, in use by the server when the RSS report was written. This component monitor returns statistics about actual server memory usage, memory allocation according to the operating system, and allocated memory, in Kilobytes, divided by the number of currently connected media players at the time the RSS report was written. System - This monitor returns the total system CPU load, including CPU used by other applications. Kernel - This monitor returns the percentage of time used by the operating system kernel on behalf of the server. User - This monitor returns the percentage of time used by the server itself, not counting operating system time and kernel time. For machines with more processors, the number may fall short in representing the actual server load. For machines with up to 4 CPUs, these statistics provide an accurate guide to the server processing load. This component monitor returns the overall use of system processor time. The script in monitors automatically determine which log file is the most recent and will retrieve statistical information from it. The entire argument should be within in double brackets. Following is an example using the arguments field:Ĭ:\Program Files\Real\Helix Server\Logs\rss ( rmserver.cfg file, " RSS Logging" section)īefore using this template, the correct arguments should be set to all PowerShell monitors. By default, the RSS interval is set to one minute in the following folder. Note: All PowerShell monitors retrieve statistical information from RSS log files which can be found here:Įach RSS configuration varies as to how many log files will be stored and how often this statistic will be updated. It is recommended to monitor counters for some length of time to understand potential value ranges and then set the thresholds accordingly. Note: You need to set thresholds for counters according to your environment. Winrm set winrm/config/client IP address is the IP address of your APM server. Winrm set winrm/config/client On the target server, open a command prompt as an Administrator and enter the following: Enter the following in the command prompt: Go to the Startmenu and right-click the cmd.exe and then select Run as Administrator.ģ. On the APM server, open a command prompt as an Administrator. If not already done so, install PowerShell 2.0 and WinRM on the APM and target servers. APM and Helix servers should be in the same domain.Ĭredentials: Domain administrator credentials on the target server (WinRM requirement).Ĭonfiguring Windows Remote Management (WinRM)ġ. Prerequisites: WinRM must be installed and properly configured on the target server. It uses PowerShell scripts to get statistics from RSS log files and WMI process monitors for monitoring Universal Media Server process. The patch for the vulnerabilities is available here.This template assesses the performance of the Real Helix Universal Media Server on Windows machines. Its widely used by companies that host webcasts and other online events. The Helix Universal Server is a back-end system designed to deliver thousands of concurrent audio streams. This, too, would result in the execution of the attackers code, according to a bulletin on the vulnerabilities released Friday by Next Generation Security Software Ltd., which discovered the issues. In order to exploit the third flaw, an attacker would need to make two simultaneous HTTP requests. Again, the attackers code would overwrite the saved return address and execute. The second vulnerability requires an attacker to send an overly long URL to the Describe field. The attackers code would then overwrite the saved return address and run with system privileges. The first flaw can be exploited by sending a large character string to the Transport field within a particular GET request. While they are all buffer overruns, each vulnerability has a different attack method. Its unknown whether any previous versions are vulnerable. The vulnerabilities, all buffer overruns, could enable an attacker to run code on remote machines.Īll of the flaws affect version 9.0 of the server running on all of the available platforms. has issued a patch for three newly discovered vulnerabilities in its Helix Universal Server media delivery software.
