MysqlReport – Makes a friendly report of important MySQL status values

Mysqlreport makes a friendly report of important MySQL status values.Actually, it makes a friendly report of nearly every status value from SHOW STATUS. Unlike SHOW STATUS which simply dumps over 100 values to screen in one long list, mysqlreport interprets and formats the values and presents the basic values and many more inferred values in a human-readable format.

The benefit of mysqlreport is that it allows you to very quickly see a wide array of performance indicators for your MySQL server which would otherwise need to be calculated by hand from all the various SHOW STATUS values. For example, the Index Read Ratio is an important value but it’s not present in SHOW STATUS; it’s an inferred value (the ratio of Key_reads to Key_read_requests).

Install Ganglia on Ubuntu 14.04 Server (Trusty Tahr)

Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. It leverages widely used technologies such as XML for data representation, XDR for compact, portable data transport, and RRDtool for data storage and visualization. It uses carefully engineered data structures and algorithms to achieve very low per-node overheads and high concurrency. The implementation is robust, has been ported to an extensive set of operating systems and processor architectures, and is currently in use on thousands of clusters around the world. It has been used to link clusters across university campuses and around the world and can scale to handle clusters with 2000 nodes.
