srpwho.d
Reports SRP Events on a Remote HCA Port
This simple script produces a report of the remote HCA port and a count of srp events. This is intended to provide a quick summary of srp
activity when run on the SRP target server:
#!/usr/sbin/dtrace -s #pragma D option quiet dtrace:::BEGIN { printf("Tracing... Hit Ctrl-C to end.\n"); } srp:::login-command, srp:::login-response, srp:::task-command, srp:::task-response, srp:::scsi-command, srp:::scsi-response, srp:::xfer-start, srp:::xfer-done { @events[args[0]->ci_remote, probename] = count(); } dtrace:::END { printf(" %-33s %14s %8s\n", "REMOTE GID", "iSCSI EVENT", "COUNT"); printa(" %-33s %14s %@8d\n", @events); }
This output shows the host and the number of iSCSI operations:
# dtrace -s ./srpwho.d
Tracing... Hit Ctrl-C to end.
