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 ctdb + +Installation +============ + + + # cd $PCP_PMDAS_DIR/ctdb + + + Check that there is no clash in the Performance Metrics Domain + defined in ./domain.h and the other PMDAs currently in use (see + $PCP_PMCDCONF_PATH). If there is, edit ./domain.h to choose another + domain number. + + + Then simply use + + # ./Install + + and choose both the "collector" and "monitor" installation + configuration options. + + You will be prompted to choose either a daemon implementation + or a DSO implementation of the PMDA, and in the case of the daemon + variant to select an IPC method -- everything else is automated + +De-installation +=============== + + + Simply use + + # cd $PCP_PMDAS_DIR/ctdb + # ./Remove + +Troubleshooting +=============== + + + After installing or restarting the agent, the PMCD log file + ($PCP_LOG_DIR/pmcd/pmcd.log) and the PMDA log file + ($PCP_LOG_DIR/pmcd/pmda_ctdb.log) should be checked for any warnings + or errors. + + +Adding a New Metric +=================== + +This section walks through the development task of adding a new metric to the +CTDB PMDA. + + + Define the metric in the pmns file with a unique metric id. See the pmns(4) + man page for details. + + + Add a description of the metric to the help file. + + + Taking note of the previously assigned metric id, add a new entry to the + metrictab structure in pmda_ctdb.c. See the pmdaInit(3) man page for + details. + + + Ensure the counter is already a member of the ctdb_statistics structure. + Finally, add code to pmda_ctdb_fetch_cb() to handle fetch requests for the + newly defined metric. diff --git a/ctdb/utils/pmda/Remove b/ctdb/utils/pmda/Remove new file mode 100644 index 0000000..7d1c509 --- /dev/null +++ b/ctdb/utils/pmda/Remove @@ -0,0 +1,29 @@ +#! /bin/sh +# +# Copyright (c) 1997 Silicon Graphics, Inc.
