Basic Commands for Synthetic

[xu_guo]

HTTP Monitor

• If the HTTP monitor fails on the AG what are the troubleshooting steps? Verify if the request works on the AG itself and request for the logs of the output of curl command.

  • No proxy:

    curl –vvv –i –k –L -H "User-Agent: DynatraceSynthetic/1.179" url

  • Proxy:

    curl –vvv –i –k –L -H "User-Agent: DynatraceSynthetic/1.179" –x http(s)://proxyhost:proxyport –proxy-user username:password url

  • Auth: Adjust URL to this: https://username:password@test.com

• If an HTTP Monitor Times out. Verify that the request is not taking longer than 10 seconds (default). Run the following from ActiveGate (If required add proxy configs from above):

  • time curl –vvv –i –k –L -H "User-Agent: DynatraceSynthetic/1.179 url

Browser Monitor (ClickPath)

• If the Browser Monitor is having connection issues, verify if the request works on the AG itself and request for the logs of the output of curl command

  • Without GUI on private synthetic location

cd ~ export DISPLAY=:99; /opt/dynatrace/synthetic/browser --headless --screenshot https://<site-of-interest>

A full command line example with our extension loaded would look something like

cd ~ export DISPLAY=:99;  /opt/dynatrace/synthetic/browser --user-data-dir=/var/tmp/dynatrace/synthetic/cache/vuc_work_diagnostics --disk-cache-dir=/var/tmp/dynatrace/synthetic/cache/vuc_work_diagnostics_cache --disk-cache-size=104857600 --disable-popup-blocking --ssl-version-min=tls1 --test-type --ignore-certificate-errors --no-default-browser-check --no-first-run --disable-translate --disable-web-security --disable-background-networking --disable-plugins-discovery --dns-prefetch-disable --noerrdialogs --disable-default-apps --disable-desktop-notifications --disable-crl-sets --allow-outdated-plugins --always-authorize-plugins --disable-web-resources --silent-debugger-extension-api --disable-internal-flash --disable-bundled-ppapi-flash --disable-appcontainer --user-agent="Mozilla/5.0 (X11; Ubuntu; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.87 Safari/537.36 RuxitSynthetic/1.0 v87769033 t7840928177123288742" --load-extension=/opt/dynatrace/synthetic/vucontroller/playback/playbackengine,/opt/dynatrace/synthetic/vucontroller/playback/websocketextension --disable-extensions-except=/opt/dynatrace/synthetic/vucontroller/playback/playbackengine,/opt/dynatrace/synthetic/vucontroller/playback/websocketextension --window-size=1024,768 --window-position=100,100 --proxy-server="http=<proxy-host>:<proxy-port>;https=<proxy-host>:<proxy-port>;" --proxy-bypass-list="localhost;<list-of-coma-separated-hosts>;" --headless --screenshot http(s)://<site-of-interest>

With GUI on private synthetic location default path: /usr/bin/chromium-browser (double click on the chromium browser to start up and use just like the chrome browser)

On Windows with redirects following and printing raw response:

Invoke-WebRequest -MaximumRedirection 10 -Uri "<url you are testing>" | Select-Object -Expand RawContent
