DTrace

• A dynamic troubleshooting and analysis technology first

introduced in Solaris 10 :

– a tool

– a programming language & interpreter

– an instrumentation framework

• Provides observability across the entire software stack

from one tool, allows to examine software execution like

never before.


DTrace in Action

Probes : Which events we are interested in monitoring

Predicates (optional) : When do we want to monitor the events

Actions (optional): What do we want to do when the above happens

One liner syntax : #dtrace –n 'probe /predicate/ {actions}'

Script syntax: #!/usr/bin/dtrace -s

probe description

/predicate/

{

actions

}


DTrace in Solaris 11

• USDT provider for Kerberos

• Networking providers for TCP, UDP and IPv4/6 protocols

• Storage providers for SMB and iSCSI

• CPC provider for processor-related events

• DTrace-based implementation of LatencyTOP

• Integration of DTrace with runtime languages


DTrace Toolkit

Over 230 scripts

Installed by default in Solaris 11

/usr/dtrace/DTT

More examples at /usr/demo/dtrace (also in Solaris 10)

Documentation, man pages, user guide

Each category has its own sub-directory

Most used scripts in top-level directory
