As you may well know OnCommand Performance Manager 1.1RC1 was recently released which added the ability to send data to an external system such as Graphite. I have created the following tutorial which explains how to setup a CentOS server and install the Graphite application on it. If you run into any issues with the tutorial please let me know in the comment section below.
Provision a CentOS 6+ VM with the “Base” package group installed
Install the “EPEL” mirror on the system
rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm Install the appropriate RPM packages
yum install graphite-web graphite-web-selinux mysql mysql-server MySQL-python python-carbon -y Start MySQL and enable the service to start at boot
/etc/init.d/mysqld start chkconfig mysqld on Execute the “mysql_secure_installation” script and accept the defaults
mysql_secure_installation Add the following lines underneath the “Database Configuration” section of the “/etc/graphite-web/local_settings.py” config file
DATABASES = { 'default': { 'NAME': 'graphite', 'ENGINE': 'django.db.backends.mysql', 'USER': 'graphite', 'PASSWORD': 'netapp1-', 'HOST': 'localhost', 'PORT': '3306' } } Create the “graphite” MySQL user along with the appropriate permission entries
mysql -e "CREATE USER 'graphite'@'localhost' IDENTIFIED BY 'netapp1-';" -u root -p mysql -e "GRANT ALL PRIVILEGES ON graphite.* TO 'graphite'@'localhost';" -u root -p mysql -e "CREATE DATABASE graphite;" -u root -p mysql -e 'FLUSH PRIVILEGES;' -u root -p Create the appropriate MySQL database and tables which will be used by graphite
/usr/lib/python2.6/site-packages/graphite/manage.py syncdb Change the value for the “MAX_CREATES_PER_MINUTE” setting in the “/etc/carbon/carbon.conf” configuration file
MAX_CREATES_PER_MINUTE = 200 Add the following lines to the “/etc/carbon/storage-schemas.conf” config file
[OPM] pattern = ^netapp-performance\..* retentions = 5m:100d Create the “/etc/carbon/storage-aggregation.conf” file with the following content
# Aggregation methods for whisper files. Entries are scanned in order, # and first match wins. This file is scanned for changes every 60 seconds # # [name] # pattern = <regex> # xFilesFactor = <float between 0 and 1> # aggregationMethod = <average|sum|last|max|min> # # name: Arbitrary unique name for the rule # pattern: Regex pattern to match against the metric name # xFilesFactor: Ratio of valid data points required for aggregation to the next retention to occur # aggregationMethod: function to apply to data points for aggregation # [min] pattern = \.min$ xFilesFactor = 0.1 aggregationMethod = min [max] pattern = \.max$ xFilesFactor = 0.1 aggregationMethod = max [sum] pattern = \.count$ xFilesFactor = 0 aggregationMethod = sum [default_average] pattern = .* xFilesFactor = 0.5 aggregationMethod = average Add the following line to the “/etc/httpd/conf.d/graphite-web.conf” configuration file underneath “Alias /media/”
Alias /content/ "/usr/share/graphite/webapp/content/" Fix the following filesystem permission issues
chmod 775 /var/log/graphite-web/ chmod 775 /var/lib/graphite-web/ Start the “carbon-cache” & “httpd" services and enable them to start at boot
/etc/init.d/carbon-cache start chkconfig carbon-cache on /etc/init.d/carbon-aggregator start chkconfig carbon-aggregator on /etc/init.d/httpd start chkconfig httpd on Complete the “Configuring a connection from a Performance Manager server to an external data provider” steps outlined in the “OnCommand Performance Manager 1.1 Installation and Administration Guide For VMware Virtual Appliances” document found here. This will enable performance data to be sent from the OPM server to the new graphite server
After waiting 5 or so minutes you should now see all of the appropriate OPM data points within Graphite under the “netapp-performance” folder
