Record metrics from a remote system
###############################################
1. Setup instructions for client systems
* Install required packages:
.. code-block:: bash
# dnf -y install pcp
* Allow incoming connections on TCP/44321:
.. code-block:: bash
# firewall-cmd --permanent --zone=public --add-port=44321/tcp
# firewall-cmd --reload
* Ensure that PMCD talks to the outer world:
.. code-block:: bash
# if grep -q ^PMCD_LOCAL /etc/sysconfig/pmcd; then
sed -ie 's,PMCD_LOCAL.*,PMCD_LOCAL=0,' /etc/sysconfig/pmcd
else
echo 'PMCD_LOCAL=0' >>/etc/sysconfig/pmcd
fi
# grep ^PMCD_LOCAL /etc/sysconfig/pmcd
PMCD_LOCAL=0
* Restart & activate PMCD:
.. code-block:: bash
# systemctl restart pmcd
# systemctl enable pmcd
2. Setup instructions for collector system
* Install required packages:
.. code-block:: bash
# dnf -y install pcp-zeroconf
* Create a default config for the clients:
.. code-block:: bash
# CLIENT='rhel7u8a'
# pmlogconf /var/lib/pcp/config/pmlogger/config.$CLIENT
* Optionally: execute again, to customize:
.. code-block:: bash
# pmlogconf /var/lib/pcp/config/pmlogger/config.$CLIENT
* Create the controller config for the client:
.. code-block:: bash
# echo "$CLIENT.local n n PCP_ARCHIVE_DIR/$CLIENT.local" " -r -T30d -c config.$CLIENT" \
>/etc/pcp/pmlogger/control.d/$CLIENT
* Restart pmlogger:
.. code-block:: bash
# systemctl restart pmlogger
3. Verify data collection on collector system
.. code-block:: bash
# pcp
