basic setup outlined in the General Setup section.

LTTng is run on the target system by ssh'ing to it.

However, if you want to see the traces graphically,
|

install Eclipse as described in section

"<link linkend='manually-copying-a-trace-to-the-host-and-viewing-it-in-eclipse'>Manually copying a trace to the host and viewing it in Eclipse (i.e. using Eclipse without network support)</link>"

view them in Eclipse (i.e. using Eclipse without network support).

Be sure to download and install/run the 'SR1' or later Juno release

of eclipse e.g.:

If you already have an LTTng trace on a remote target and
|
||||
would like to view it in Eclipse on the host, you can easily
|
||||
copy it from the target to the host and import it into
|
||||
Eclipse to view it using the LTTng Eclipse plug-in already
|
||||
bundled in the Eclipse (Juno SR1 or greater).

Using the trace we created in the previous section, archive
|

it and copy it to your host system:

<note>
|

This section on collecting traces remotely doesn't currently
|
||||
work because of Eclipse 'RSE' connectivity problems. Manually
|

tracing on the target, copying the trace files to the host,
|
||||
and viewing the trace in Eclipse on the host as outlined in

previous steps does work however - please use the manual

steps outlined above to view traces in Eclipse.

|

In order to trace a remote target, you also need to add
|

a 'tracing' group on the target and connect as a user
|

who's part of that group e.g:
|
||||
<literallayout class='monospaced'>

# adduser tomz
