Glossary

This page contains definitions for terminology used throughout Exoprise CloudReady

  • Bandwidth
    The rate of data transfer, bit rate or throughput, typically measured in bits per second (bits/s) or a derivative of bits per second. Often used interchangeably as available bandwidth and consumed bandwidth.
  • Dashboard
    Dashboards within the CloudReady console are composed of different layouts or tabs. There are two primary dashboards; Personal and Shared.
  • DNS
    DNS is the system in which user friendly names like www.exoprise.com are translated into IP addresses.
  • ICMP
    ICMP or Internet Control Message Protocol is a supporting protocol in the Internet protocol suite. It is used by network devices, including routers, to send error messages and operational information indicating, for example, that a requested service is not available or that a host or router could not be reached. Internet tracing to determine hop-by-hop speed leverages ICMP packets for the return path notifications.
  • Jitter
    In telecommunications, Jitter is a measure of the variance of something when presumably it should be a regular periodic entity. For example, in audio or video conversations the delivery should be a regular stream of packets but the jitter measures how irregular the packets are which can have an effect on the quality of the audio/video conversation.
  • Layout
    Layouts are containers for widgets within the CloudReady Dashboards, often also referred to as tabs. There are some pre-configured layouts available such as the preview layout or Office 365 layout.
  • Message Transfer Agent (MTA)
    Message Transfer Agent or Mail Transfer Agent is the mail relay server and software that is responsible for transferring email messages from one computer to another. Within the CloudReady system, we refer to mail flow performance as MTA statistics.
  • Mean Opinion Score (MOS)
    Mean Opinion Score is a metric used to quantify Quality of Experience with respect to telecommunications. It is often computed as the mean of values on a predefined scale between 1 and 5 with 1 being a poor experience and 5 being an excellent experience.
  • Private Site
    A Private Site is a Windows® service that runs on any of your computers or Virtual Machines. Deploy a Private Site then configure sensors for the site. Private Sites run from behind your firewall on your computers for monitoring the end-user experience from your environment. You can also think of a Private Site as an agent.
  • Public Site
    CloudReady Public Sites are managed by Exoprise at various locations throughout the world and are great for comparing against internal LAN/WAN conditions. Public Sites are also important for monitoring and measuring end-user experience form outside the corporate LAN/MPLS/WAN. Read more about Public and Private sites.
  • Round Trip Time (RTT)
    In networking, the round-trip delay time or round-trip time is the length of time it takes for a packet to be sent plus the length of time it takes for an acknowledgement of that signal to be received.
  • Sensor
    A sensor monitors 1 application from one site emulating an end-user to give you the end-user perspective of different services.
  • Secure Sockets Layer (SSL)
    Secure Sockets Layer is a standard security protocol for establishing encrypted links between a web server and a browser in an online communication.
  • SSO or Single Sign-On
    The ability for a user to sign into cloud and web-based services without having to enter credentials again. The sign-in process is integrated with the Lightweight Directory Access Protocol (LDAP).
  • SSL Negotiate Time
    The length of time it takes to establish an SSL connection between a client and a server. The negotiation of SSL connections involves some quick back and forth and is considered “chatty” on a network. Slow SSL negotiate times are usually indicative of higher latency in a network path.
  • UDP or (User Datagram Protocol)
    User Datagram Protocol is an alternative communications protocol to Transmission Control Protocol (TCP), is a “connectionless” protocol with a minimum of mechanisms compared to TCP/IP. UDP datagrams are sent without guarantee of delivery, ordering, or duplicate protection but is generally faster delivery with less overhead than TCP.
  • Wait time
    Depending on the type of service being monitored, Wait time is calculated as the ability to successfully send packets to the service or the delay in waiting for a server to respond to a request.
  • TCP/IP
    TCP/IP, or the Transmission Control Protocol/Internet Protocol, is one of the main protocols used to interconnect network devices on the internet. TCP/IP provides reliable, ordered, and error-checked delivery of a stream of (bytes) between applications running on hosts communicating via an IP network.
  • TTFB
    Time to First Byte is a measurement used as an indication of the responsiveness of a webserver or other network resource. TTFB measures the duration from the user or client making a request to the server and the first byte of data being received back from the server.
  • VoIP or Voice over Internet Protocol
    A group of technologies for transmitting voice data and communications over Internet Protocol networks such as the Internet.
  • WGET
    WGET stands for web get. It often refers to the traditional Unix/Linux tool with the same name. Web gets are simple HTTP transactions against a web server that tests for web server performance and availability. With web gets the entire page is not retrieved, just the top-level page request against a server. CloudReady WGET sensors can monitor up to 5 different URLs (or servers) from a single sensor deployment.
  • Widget
    A widget is a sub-window or tile that exist within the layouts and dashboards in CloudReady. Widgets are for visualizing cloud performance data in real-time or historically.
