The scripts found in [.filename]#/usr/share/dtrace# have been specifically ported to FreeBSD. Not all of the scripts found in the DTrace Toolkit will work as-is on FreeBSD and some scripts may require some effort in order for them to work on FreeBSD.
Os scripts encontrados em <filename>/usr/share/dtrace</filename> foram especificamente portados para o FreeBSD. Nem todos os scripts encontrados no DTrace Toolkit funcionarão no FreeBSD e alguns scripts podem exigir algum esforço para que funcionem no FreeBSD.

Finally, install the current DTrace Toolkit, a collection of ready-made scripts for collecting system information. There are scripts to check open files, memory, `CPU` usage, and a lot more. FreeBSD 10 installs a few of these scripts into [.filename]#/usr/share/dtrace#. On other FreeBSD versions, or to install the full DTrace Toolkit, use the package:sysutils/DTraceToolkit[] package or port.
Por fim, instale o DTrace Toolkit atual, uma coleção de scripts prontos para coletar informações do sistema. Existem scripts para verificar arquivos abertos, memória, uso de <acronym>CPU</acronym> e muito mais. O FreeBSD 10 instala alguns desses scripts em <filename>/usr/share/dtrace</filename>. Em outras versões do FreeBSD, ou para instalar o DTrace Toolkit completo, use o pacote ou port <package>sysutils/DTraceToolkit</package>.

The [.filename]#hotkernel# script is designed to identify which function is using the most kernel time. It will produce output similar to the following:
O script <filename>hotkernel</filename> é projetado para identificar qual função está usando a maior parte do tempo do kernel. Ele produzirá uma saída semelhante à seguinte:

DTrace scripts consist of a list of one or more _probes_, or instrumentation points, where each probe is associated with an action. Whenever the condition for a probe is met, the associated action is executed. For example, an action may occur when a file is opened, a process is started, or a line of code is executed. The action might be to log some information or to modify context variables. The reading and writing of context variables allows probes to share information and to cooperatively analyze the correlation of different events.
Os scripts do DTrace consistem em uma lista de um ou mais testes <firstterm>probes</firstterm>, ou pontos de instrumentação, em que cada teste é associado a uma ação. Sempre que a condição de uma sonda é atendida, a ação associada é executada. Por exemplo, uma ação pode ocorrer quando um arquivo é aberto, um processo é iniciado ou uma linha de código é executada. A ação pode ser registrar algumas informações ou modificar variáveis de contexto. A leitura e a escrita de variáveis de contexto permitem que os probes compartilhem informações e analisem cooperativa-mente a correlação de diferentes eventos.
