Pruebas de Stress Con herramientas OpenSource[AB-GNUPLOT]

ab - Apache HTTP server benchmarking tool ejemplo del AB con una peticion GET: ab: The Apache Bench benchmarking utility -n 400: The number of requests for your benchmark (yes, this one is crazy small; it’s so people don’t hammer example.com by copy pasting) -c 10: Number of concurrent requests -g apache-1.tsv: This tells ab to write a “gnuplot-file” (that’s right from the man page) "http://example.com": The URL you want to benchmark against

ab -k -n50000 -c100 "172.29.151.82:17503/v1/pcrf/provisioning/subscriber/56911111112?platform=SCOB"

ej: del AB para una petición POST:

ab -g resultcreatePD.plot -k -T "content-type: text/xml" -H "SOAPAction: createPD" -p POST_crearpasediario.txt -n 10000 -c 400 http://localhost:17506/v1/WSPASEDIARIO

Ahora la opción -g nos entrega una salida un archivo de texto plano con los valores. EJ:

Esos valores se pueden graficar para crear un gráfico de dispersión: gnuplot es un programa muy flexible para generar gráficas de funciones y datos. Este programa es compatible con los sistemas operativos más populares (Linux, UNIX, Windows, Mac OS X...). El origen de gnuplot data de 1986. gnuplot puede producir sus resultados directamente en pantalla, así como en multitud de formatos de imagen, como PNG, EPS, SVG, JPEG, etc. Se puede usar interactivamente o en modo por lotes (batch), usando scripts.
