-NOTE! The samba.c source in this directory has been removed pending
-approval from SGI to use it under the GPLv3 license.
-
-Please see Samba 3.0.xx for a copy of this code under the GPLv2
-license if required.
-
-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 and Perl 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/include/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.
