How can I DTrace network details on Solaris?
Networking can also be a bottleneck, as even multiple 1-Gb links can be slower than other system aspects. Even with Solaris 10, network bottlenecks can be difficult to spot owing to the lack of a DTrace networking provider.That provider was included in Solaris Nevada build 93, so it is in OpenSolaris and it should appear in a future Solaris release. For details see Sun’s wiki (http://wikis.sun.com/display/DTrace/ip+Provider). In the meantime a good tool is nicstat, also available online (http://www.brendangregg.com/K9Toolkit/nicstat).
