Appendix C. Capacity Tools
MEASUREMENT, MONITORING, AND MANAGEMENT TOOLS INFORM AND GUIDE YOUR CAPACITY PLAN. IN THIS appendix, I’ve compiled a list of some of the more popular tools and utilities for your reference. We use a good deal of these tools at Flickr, and some of them are simply open-source equivalents of software that have been written within Yahoo! to achieve the same goal.

Some of the following tools have alerting abilities, some of them are more focused on graphing and collection, and some have both.
Metric Collection and Event Notification Systems
- Ganglia, http://ganglia.info
Born out of the HPC community, Ganglia has a very active community of users and developers. We use Ganglia extensively at Flickr, as do Wikipedia and other large-scale social networking sites.
- Nagios, http://nagios.org
We use a modified version of Nagios at Yahoo! to monitor services across thousands of machines.
Cacti, http://cacti.net
Zabbix, http://zabbix.com
Hyperic HQ, http://hyperic.com
Munin, http://munin.projects.linpro.no/
ZenOSS, http://www.zenoss.com/
OpenNMS, http://opennms.org
- GroundWork, http://www.groundworkopensource.com/
GroundWork is a hybrid of Nagios and Ganglia.
