Nagios XI - Leveraging and Understanding Performance Data and Graphs - NWC13
Leveraging and Understanding Performance Data and Graphs
In the world of monitoring, there is more to Nagios than simply sending alerts because a server is about to run out of hard disk space. Collecting and storing performance data is one of the most useful features in Nagios. With this information, you can get an understanding of your environment's day to day trends. Analyzing this data can be very helpful; perhaps to look at growth, or identifying performance bottlenecks. This session is about understanding how the performance data is stored in the back end and how Nagios accesses it. Topics include understanding the .rrd and .xml files, understanding how pnp generated graphs, creating custom graph templates in pnp, and writing plug-ins that will output the performance data you want.
