ZBXPCP(3) Library Functions Manual ZBXPCP(3)
zbxpcp - Zabbix Agent Loadable PCP Module
The zbxpcp loadable module extends Zabbix agent by making
Performance Co-Pilot (PCP) metrics available to it. With the
zbxpcp module configured in zabbix_agentd.conf all the PCP metrics
are available from the Zabbix agent like any other agent items.
As a loadable module (DSO) zbxpcp does not rely on any external
programs but directly uses the PCP APIs to fetch PCP metrics when
requested.
A typical Linux PCP installation offers over 1,000 metrics by
default and is in turn extensible with its own plugins, or PMDAs
(``Performance Metrics Domain Agents''). In addition to very
complete /proc based statistics, readily available PCP PMDAs
provide support for such system and application level components
as 389 Directory Server, Apache, containers, HAProxy, GFS2,
Gluster, libvirt, MySQL, NFS, Oracle, Postfix, PostgreSQL, Samba,
and Sendmail, among others. PCP also runs on many platforms,
including Linux, Mac OS X, FreeBSD, NetBSD, Solaris, and Windows.
For PCP introduction, see PCPIntro(1). To investigate the
available PCP metrics, use for example pminfo(1). The PCP Quick
Reference Guide is available at the PCP home page https://pcp.io/.
For general information about Zabbix data collection and loadable
modules, see
https://www.zabbix.com/documentation/3.0/manual/config/items. For
Zabbix introduction and downloads, see https://www.zabbix.com/.
zbxpcp is compatible with the Zabbix module API version 1.
First make sure PCP is installed and configured properly, see the
above references for instructions and use for example pminfo(1) to
make sure the PCP metrics can be fetched. To enable the zbxpcp
loadable module in a Zabbix agent, the following lines must be
added to the Zabbix agent configuration file zabbix_agentd.conf
(make sure to use the correct LoadModulePath):
LoadModulePath=/usr/lib64/zabbix/agent/
LoadModule=zbxpcp.so
After restarting the Zabbix agent all the PCP metrics will be
available with the ``pcp.'' prefix like all the other agent
items. This can be verified with the commands:
$ pminfo -t
$ zabbix_agentd -p
$ pminfo -f kernel.all.sysfork
$ zabbix_get -s 127.0.0.1 -p 10050 -k pcp.kernel.all.sysfork
Then to collect PCP metrics from Zabbix agents, the Zabbix server
side configuration is as usual (see Zabbix documentation if
needed).
The PCP pmcd service must always be running when starting up a
zbxpcp enabled Zabbix agent, otherwise the module will fail to
load and the PCP metrics will not become available. Special care
must be taken to make sure this happens also when rebooting the
system.
/etc/zabbix/zabbix_agentd.conf
Typical Zabbix agent configuration file location.
/etc/zabbix/zbxpcp-derived-metrics.conf
Optional PCP derived metrics configuration file for zbxpcp.
See pmLoadDerivedConfig(3) for more info on derived
metrics.
$PCP_LIB_DIR/zabbix/agent/zbxpcp.so
Zabbix agent loadable PCP module.
