NAMEpmdabind2 − BIND performance metrics domain agent (PMDA)
DESCRIPTIONThis PMDA extracts performance data from BIND (Berkeley Internet Name Domain). It enables collection of most of the statistics metrics from the Bind server version 9 or later, which includes: • overall memory statistics • overall per-query statistics (general queries, EDNS/truncated responses, Update/Notify/AXFR/IXFR messages) • overall error statistics (Rejected, SERVFAIL, Update/XFR failures ...) • overall statistics per transport protocol, EDNS and per version of IP protocol • resolver statistics (successes, errors, round-trip times in several ranges) • detailed per-socket statistics with respect to the transport protcol and IP version including errors • detailed per-file-descriptor statistics including errors The PMDA performs per-second collection of the whole data set (148 metrics on the test environment) with modest requirements (2% CPU usage on Intel i7-4700MQ @2.4 GHz, cca 30 MB RAM). If more than 1 requests/sec is performed, the memoized values are used so that the statistics interface of the Bind server does not get overloaded.
INSTALLATIONConfigure BIND to export XML statistics via its REST interface. This requires BIND configuration to enable statistics exporting locally (at least). statistics-channels {
inet 127.0.0.1 port 8080 allow { 127.0.0.1; };
}
options { zone-statistics yes; }
# ./InstallThe hostname (localhost), port (8080 above) and other configuration information must be specified in both the BIND configuration file as well as the $PCP_PMDAS_DIR/bind2/bind2.conf file. # cd $PCP_PMDAS_DIR/bind2
# [ edit bind2.conf ]
host=localhost.localdomain:8080Once this is setup, you can access the names and values for the bind2 performance metrics by doing the following as root: # cd $PCP_PMDAS_DIR/bind2
# ./InstallTo uninstall, the following must be done as root: # cd $PCP_PMDAS_DIR/bind2
# ./Removepmdabind2 is launched by pmcd(1) and should never be executed directly. The Install and Remove scripts notify pmcd(1) when the agent is installed or removed.

PCP ENVIRONMENTEnvironment variables with the prefix PCP_ are used to parameterize the file and directory names used by PCP. On each installation, the file /etc/pcp.conf contains the local values for these variables. The $PCP_CONF variable may be used to specify an alternative configuration file, as described in pcp.conf(5).
