4 This PMDA is a sample that illustrates how a simple samba monitor
5 PMDA might be constructed, using a shared memory segment to transfer
6 information about transaction activity from the smb and nmbd daemons.
9 This PMDA may be remade from source and hence requires
10 a C compiler and Perl to be installed.
12 Uses of make(1) may fail (without removing or clobbering files)
13 if the C compiler cannot be found. This is most likely to
14 happen when running the PMDA ./Install script.
16 The only remedial action is to install the C compiler, or
17 hand-craft changes to the Makefile.
22 The file ./help contains descriptions for all of the metrics exported
25 Once the PMDA has been installed, the following command will list all
26 the available metrics and their explanatory "help" text:
33 + # mkdir /var/pcp/pmdas/samba
34 + # cp * /var/pcp/pmdas/samba
35 + # cp ../source/include/profile.h /var/pcp/pmdas/samba
36 + # cd /var/pcp/pmdas/samba
38 + Check that there is no clash in the Performance Metrics Domain
39 defined in ./domain.h and the other PMDAs currently in use
40 (/etc/pmcd.conf). If there is, edit ./domain.h to choose another
43 + If you are not installing on an IRIX system, edit samba.c and
52 + Alternatively, to install just the Performance Metrics Name Space
53 for the samba metrics on the local system, but not the samba PMDA
54 (presumably because the local system is running PCP 1.x and you
55 wish to connect to a remote system where PCP 2.0 and the samba PMDA
56 is running), make sure the Performance Metrics Domain defined in
57 ./domain.h matches the domain chosen for the samba PMDA on the
58 remote system (check the second field in the corresponding line of
59 the pmcd.conf file on the remote system - located in /etc on IRIX
60 and /var/pcp/config/pmcd on Linux), then
69 # cd /var/pcp/pmdas/samba
72 + If you also want to remove the sources use
75 # rm -rf /var/pcp/pmdas/samba
77 Making something happen
78 =======================
80 Samba must have been compiled with profiling data collection enabled.
81 Use the --with-profiling-data option for configure to enable this feature.
83 The applications "nmbd" and "smbd" update the shared memory segment to add
84 profile information about nmbd and smbd. By default updating is disabled.
85 To start updating of the shared memory segment you need to run the
86 smbcontrol command to turn on profiling for nmbd or one or more smbd
87 processes (see the man page for smbcontrol).
94 + After installing or restarting the agent, the PMCD log file
95 (pmcd.log) and the PMDA log file (samba.log) should be checked
96 for any warnings or errors. These logs are located in
97 /var/log/pcp/pmcd on Linux and /var/adm/pcplog on IRIX.
