Automated management and remediation processes, supported by tools such as AWS CloudWatch, Azure Monitor, and Google Cloud Operations Suite, help detect and respond to large-scale failures. Despite these tools, managing QoS in highly distributed and multi-tenant systems remains complex.
In computing, virtual machine introspection (VMI) is a technique "for monitoring the runtime state of a system-level virtual machine (VM)", which is helpful for debugging or forensic analysis. [1] [2] The term introspection in application to the virtual machines was introduced by Garfinkel and Rosenblum. [3]
A queue is a temporary storage location from which messages can be sent and received reliably, as and when conditions permit. This enables communication across networks and between computers, running Windows, which may not always be connected. By contrast, sockets and other network protocols assume that direct connections always exist.
Microsoft released Version 5 of App-V in late November 2012, which is a third generation major redesign of the entire platform. Version 5 modernized the product, replacing components designed for use originally against Windows NT and Windows 2000 some 11 years earlier.
Programmers typically use debugging NMIs to diagnose and fix faulty code. In such cases, an NMI can execute an interrupt handler that transfers control to a special monitor program. From this program, a developer can inspect the machine's memory and examine the internal state of the program at the instant of its interruption.
Hyper-V is a native hypervisor developed by Microsoft; it can create virtual machines on x86-64 systems running Windows. [1] It is included in Pro and Enterprise editions of Windows NT (since Windows 8) as an optional feature to be manually enabled. [2]
High-availability clusters usually use a heartbeat private network connection which is used to monitor the health and status of each node in the cluster. For example, the split-brain syndrome may occur when all of the private links go down simultaneously, but the cluster nodes are still running, each one believing they are the only one running.
On 19 July at 04:09 UTC, CrowdStrike distributed a faulty configuration update for its Falcon sensor software running on Windows PCs and servers. A modification to a configuration file which was responsible for screening named pipes, Channel File 291, caused an out-of-bounds memory read [14] in the Windows sensor client that resulted in an invalid page fault.
