| 1 | samba PMDA
|
|---|
| 2 | ===========
|
|---|
| 3 |
|
|---|
| 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 daemon.
|
|---|
| 7 |
|
|---|
| 8 | Note:
|
|---|
| 9 | This PMDA may be remade from source and hence requires
|
|---|
| 10 | a C compiler and Perl to be installed.
|
|---|
| 11 |
|
|---|
| 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.
|
|---|
| 15 |
|
|---|
| 16 | The only remedial action is to install the C compiler, or
|
|---|
| 17 | hand-craft changes to the Makefile.

| 19 | Metrics
|
|---|
| 20 | =======
|
|---|
| 21 |
|
|---|
| 22 | The file ./help contains descriptions for all of the metrics exported
|
|---|
| 23 | by this PMDA.
|
|---|
| 24 |
|
|---|
| 25 | Once the PMDA has been installed, the following command will list all
|
|---|
| 26 | the available metrics and their explanatory "help" text:
|
|---|
| 27 |
|
|---|
| 28 | $ pminfo -fT samba
|
|---|
| 29 |
|
|---|
| 30 | Installation
|
|---|
| 31 | ============
|
|---|
| 32 |
|
|---|
| 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
|
|---|
| 37 |
|
|---|
| 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
|
|---|
| 41 | domain number.
|
|---|
| 42 |
|
|---|
| 43 | + If you are not installing on an IRIX system, edit samba.c and
|
|---|
| 44 | comment out the
|
|---|
| 45 |
|
|---|
| 46 | #define IRIX 1
|
|---|
| 47 |
|
|---|
| 48 | + Then simply use
|
|---|
| 49 |
|
|---|
| 50 | # ./Install
|
|---|
| 51 |
|
|---|
| 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
|
|---|
| 61 |
|
|---|
| 62 | # ./Install -N
|
|---|
| 63 |
|
|---|
| 64 | De-installation
|
|---|
| 65 | ===============
|
|---|
| 66 |
|
|---|
| 67 | + Simply use
|
|---|
| 68 |
|
|---|
| 69 | # cd /var/pcp/pmdas/samba
|
|---|
| 70 | # ./Remove
|
|---|
| 71 |
|
|---|
| 72 | + If you also want to remove the sources use
|
|---|
| 73 |
|
|---|
| 74 | # cd /
|
|---|
| 75 | # rm -rf /var/pcp/pmdas/samba
|
|---|
| 76 |
|
|---|
| 77 | Making something happen
|
|---|
| 78 | =======================
|
|---|
| 79 |
|
|---|
| 80 | The application "smbd" updates the shared memory segment to add
|
|---|
| 81 | profile information about smbd. By default updating is disabled.
|
|---|
| 82 | To start updating of the shared memory segment you need to run the
|
|---|
| 83 | smbcontrol command to turn on profiling for one or more smbd processes
|
|---|
| 84 | (see the man page for smbcontrol).
|
|---|
| 85 |
|
|---|
| 86 |
|
|---|
| 87 |
|
|---|
| 88 | Troubleshooting
|
|---|
| 89 | ===============
|
|---|
| 90 |
|
|---|
| 91 | + After installing or restarting the agent, the PMCD log file
|
|---|
| 92 | (pmcd.log) and the PMDA log file (samba.log) should be checked
|
|---|
| 93 | for any warnings or errors. These logs are located in
|
|---|
| 94 | /var/log/pcp/pmcd on Linux and /var/adm/pcplog on IRIX.
