The Server Efficiency Rating Tool (SERT) is a performance analysis tool that is specifically designed to address the requirements of the Environmental Protection Agency's ENERGY STAR for Servers v2.0 specification. [1] The SERT Beta 1 was introduced in September, 2011. [2]
Network Performance Monitor (NPM) is network monitoring from the Operations Management Suite, that monitors networks. NPM monitors the availability of connectivity and quality of connectivity between multiple locations within and across campuses, private and public clouds.
Load testing (stress/performance testing) a web server can be performed using automation/analysis tools such as: Apache JMeter, an open-source Java load testing tool; ApacheBench (or ab), a command line program bundled with Apache HTTP Server; Siege, an open-source web-server load testing and benchmarking tool; Wrk, an open-source C load ...
PA Server Monitor is a server and network monitoring software from Power Admin LLC. PA Server Monitor focuses primarily on server and network health through numerous resource checks, reports, and alerting options. The agentless, on-premises [2] software can monitor thousands of devices from a single installation.
A common scenario in the early years of computing was an overload condition known as thrashing where the aggregate server performance becomes severely degraded, such as when two departments of a large company attempt to run a heavy report concurrently on the same mainframe. In such a situation, the designation of the server hog becomes a ...
These four produced the initial version of Performance Co-Pilot 1.0, which was released in April 1995 as add-on software for SGI's IRIX operating system. Components included in that initial release were: pmcd (Ken and Jonathan), pmchart (Mark), libpcp (Ken), pmie (Seppo), pmgadgets (Jonathan), and a host of other smaller bits and pieces.
The term is borrowed from control theory, where the "observability" of a system measures how well its state can be determined from its outputs. Similarly, software observability measures how well a system's state can be understood from the obtained telemetry (metrics, logs, traces, profiling). The definition of observability varies by vendor:
In these cases, editors can certainly make use of these tools to improve the performance they can measure. "Don't worry about performance" refers to site-wide performance, where the purpose of the servers is to support the wiki contents, not the other way around. The purpose of the wiki content is to serve the reader; and performance ...
