SystemTap permite realizar una observaci\u00f3n detallada de un sistema Linux en funcionamiento, recolectar estad\u00edsticas sobre el rendimiento de las aplicaciones, realizar perfiles y controlar llamadas al sistema. La gesti\u00f3n se realiza a trav\u00e9s de una interfaz de l\u00ednea de comandos y un lenguaje de scripts parecido a C. El sistema es compatible con n\u00facleos de Linux desde la versi\u00f3n 3.10 hasta la 6.6-rc0.     <\/p>\n<p>El desarrollo del proyecto cuenta con la participaci\u00f3n de empresas como Red Hat, IBM, Intel, Hitachi y Oracle. En el cat\u00e1logo de ejemplos se presentan m\u00e1s de 190 scripts para diversas situaciones, adecuados para el seguimiento de la distribuci\u00f3n de memoria, entradas\/salidas, operaciones de disco, tr\u00e1fico de red (por ejemplo, an\u00e1lisis del funcionamiento de NFS), trabajo de planificadores de tareas, manejo de interrupciones, uso de buffers del sistema, establecimiento de bloqueos, ejecuci\u00f3n de llamadas al sistema, manejo de se\u00f1ales, etc.    <\/p>\n<p>Principales cambios:  <\/p>\n<ul>\n<li class=\"l\"> Se ha descontinuado el soporte para la rama del n\u00facleo 2.6.32 utilizada en RHEL6. Las pruebas de SystemTap ahora se realizan con n\u00facleos 3.10 (RHEL7), 4.18 (RHEL8 + CentOS Stream 8), 5.14.0 (RHEL9 + CentOS Stream 9), 6.4 (Fedora 38), 6.5 (Fedora 39) y 6.6-rc (Fedora rawhide).\n<li class=\"l\"> Se ha a\u00f1adido soporte para el proceso debuginfod para la obtenci\u00f3n din\u00e1mica de informaci\u00f3n de depuraci\u00f3n y metadatos sobre archivos ejecutables instalados.\n<li class=\"l\">  Se ha a\u00f1adido soporte para datos de depuraci\u00f3n en formato DWARF5, que se pueden utilizar en la funci\u00f3n print_ubacktrace_fileline().\n<li class=\"l\"> En el frontend (utilidad stap) se ha implementado la posibilidad de usar m\u00e1scaras al definir procesos objetivo cuando debuginfod est\u00e1 disponible. <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/es\/server\/\"   title=\"servidores\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"1660\">servidores<\/a> se ha implementado la posibilidad de usar m\u00e1scaras al determinar procesos objetivo en debuginfod. Por ejemplo, stap -e 'probe debuginfod.process(\"\/usr\/*\/curl\").begin { log(\"hi\")}'. Se ha mejorado la granularidad de la informaci\u00f3n sobre los procesos en la lista, la cual se muestra al utilizar la opci\u00f3n \"-L\" junto con varias \"-v\".\n<li class=\"l\"> En el backend, se ha mejorado el rendimiento del registro de uprobe y se ha acelerado el inicio del m\u00f3dulo del n\u00facleo. Se ha propuesto un sistema de mensajer\u00eda m\u00e1s r\u00e1pido y confiable entre el n\u00facleo y el espacio de usuario.\n<li class=\"l\"> Se han a\u00f1adido macros que se procesan en tiempo de ejecuci\u00f3n: STP_TIMING_NSECS para obtener informaci\u00f3n sobre el tiempo de verificaci\u00f3n en nanosegundos y STP_FORCE_STDOUT_TTY para anular STP_STDOUT_NOT_ATTY.     <\/ul>\n<p>Fuente: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=60051\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041e\u043f\u0443\u0431\u043b\u0438\u043a\u043e\u0432\u0430\u043d \u0440\u0435\u043b\u0438\u0437 \u0441\u0438\u0441\u0442\u0435\u043c\u044b \u0434\u0438\u043d\u0430\u043c\u0438\u0447\u0435\u0441\u043a\u043e\u0439 \u0442\u0440\u0430\u0441\u0441\u0438\u0440\u043e\u0432\u043a\u0438 SystemTap 5.0, \u043f\u0440\u0435\u0434\u043e\u0441\u0442\u0430\u0432\u043b\u044f\u044e\u0449\u0438\u0439 \u0434\u043b\u044f \u043f\u043b\u0430\u0442\u0444\u043e\u0440\u043c\u044b Linux \u0441\u0440\u0435\u0434\u0441\u0442\u0432\u0430 \u043e\u0442\u043b\u0430\u0434\u043a\u0438, \u043f\u043e\u0445\u043e\u0436\u0438\u0435 \u043d\u0430 \u0442\u0435\u0445\u043d\u043e\u043b\u043e\u0433\u0438\u044e DTrace.
