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).
