  • PRTG Catches Network Issues Before They Cause Downtime Icon
    PRTG Catches Network Issues Before They Cause Downtime

    Threshold-based alerts flag problems early, so your team can act before users notice, not after.

    Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

Tested and works with Vista/7, mileage on other platforms may vary.

The instructions on this page was followed to create it: http://www.makeuseof.com/tag/create-portable-app-flash-drive/. It is not a fully 'portable' application in the sense that it will leave cache files on the host computer (i.e. under AppData). It is put here on a 'take it or leave it' basis. It may not work for you, it may break. It is in no way endorsed by the Pheonix Project in this form. No tech support will be provided. It may be updated in the future or not. Share and Enjoy~

    Advanced Traffic Simulation

    A mixture of game and simulation for public transport.

    This project is about a game and a simulation to work together. The focus lies on public transport. Manage your line network in your home area. Upgrade your vehicles, build new roads, deal with accidents or plan replacement busses for railroad construction works. But it's also possible to drive the vehicle yourself or just walk around the world and enjoy your line network. By vehicle we mean: train, tram, subway, bus and monorail. By using an addon structure it is possible to customize the whole world or even include non-existing means of transport like the hyperloop. Plan, manage and drive all together in multiplayer. Either competing or cooperative. Discord: https://discord.gg/P3SbVuD VSTS: https://advtrafficsim.visualstudio.com/
