+samba PMDA
+===========
+
+This PMDA is a sample that illustrates how a simple samba monitor
+PMDA might be constructed, using a shared memory segment to transfer
+information about transaction activity from the smb daemon.
+
+Note:
+ This PMDA may be remade from source and hence requires
+ a C compiler to be installed.
+
+ Uses of make(1) may fail (without removing or clobbering files)
+ if the C compiler cannot be found. This is most likely to
+ happen when running the PMDA ./Install script.
+
+ The only remedial action is to install the C compiler, or
+ hand-craft changes to the Makefile.
+
+Metrics
+=======
+
+The file ./help contains descriptions for all of the metrics exported
+by this PMDA.
+
+Once the PMDA has been installed, the following command will list all
+the available metrics and their explanatory "help" text:
+
+ $ pminfo -fT samba
+
+Installation
+============
+
+ + # mkdir /var/pcp/pmdas/samba
+ + # cp * /var/pcp/pmdas/samba
+ + # cp ../source/includes/profile.h /var/pcp/pmdas/samba
+ + # cd /var/pcp/pmdas/samba
+
+ + Check that there is no clash in the Performance Metrics Domain
+ defined in ./domain.h and the other PMDAs currently in use
+ (/etc/pmcd.conf). If there is, edit ./domain.h to choose another
+ domain number.
+
+ + If you are not installing on an IRIX system, edit samba.c and
+ comment out the
+
+ #define IRIX 1
+
+ + Then simply use
+
+ # ./Install
+
+ + Alternatively, to install just the Performance Metrics Name Space
+ for the samba metrics on the local system, but not the samba PMDA
+ (presumably because the local system is running PCP 1.x and you
+ wish to connect to a remote system where PCP 2.0 and the samba PMDA
+ is running), make sure the Performance Metrics Domain defined in
+ ./domain.h matches the domain chosen for the samba PMDA on the
+ remote system (check the second field in the corresponding line of
+ the pmcd.conf file on the remote system - located in /etc on IRIX
+ and /var/pcp/config/pmcd on Linux), then
+
+ # ./Install -N
+
+De-installation
+===============
+
+ + Simply use
+
+ # cd /var/pcp/pmdas/samba
+ # ./Remove
+
+ + If you also want to remove the sources use
+
+ # cd /
+ # rm -rf /var/pcp/pmdas/samba
+
+Making something happen
+=======================
+
+The application ./smbd updates the shared memory segment to add
+profile information about smbd. By default updating is disabled.
+To start updating of the shared memory segment you need to run the
+smbcontrol command to turn on profiling for one or more smbd processes
+(see the man page for smbcontrol).
+
+
+
+Troubleshooting
+===============
+
+ + After installing or restarting the agent, the PMCD log file
+ (pmcd.log) and the PMDA log file (samba.log) should be checked
+ for any warnings or errors. These logs are located in
+ /var/log/pcp/pmcd on Linux and /var/adm/pcplog on IRIX.
