Outliers and coexistence are the new normal for big data
+0 Vote Up -0Vote Down

Letting data speak for itself through analysis of entire data sets is eclipsing modeling from subsets. In the past, all too often what were once disregarded as "outliers" on the far edges of a data model turned out to be the telltale signs of a micro-trend that became a major event. To enable this advanced analytics and integrate in real-time with operational processes, companies and public sector organizations are evolving their enterprise architectures to incorporate new tools and approaches.

Whether you prefer "big," "very large," "extremely large," "extreme," "total," or another adjective for the "X" in the "X Data" …

MySQL Analytics: updated query for table engine data statistics
+1 Vote Up -0Vote Down

This is a follow up to my previous post titled “MySQL analytics: information_schema polling for table engine percentages”. Here’s an updated query with more output and quicker execution time. What you get: innodb table space utilization percentage, data+index usage total and per innodb/myisam engine, innodb data/index/percentage, myisam data/index/percentages, and overall percentage values. Rather useful for profiling your table engine usage.

Sample output:
innodb_tablespace_utilization_perc: 100
total_size_gb: 26.275011910126
index_size_gb: 2.994891166687
data_size_gb: 23.280120743439
innodb_total_size_gb: …

Not excited about paying for MySQL monitoring for your enterprise?
+1 Vote Up -2Vote Down

I think most people will agree that one of the biggest advantages of MySQL Community Server is that it’s free. Being free doesn’t get you a multi-million user community though; MySQL offers a great array of transactional engines, advanced high-availability features, robust I/O performance, and it powers many of the top-500 internet sites. When it […]

MySQL analytics: information_schema polling for table engine percentages
+1 Vote Up -0Vote Down

If you’ve ever needed to know how the data and index percentages per table engine were laid out on your MySQL server, but didn’t have the time to write out a query… here it is!

select
(select (sum(DATA_LENGTH)+sum(INDEX_LENGTH))/(POW(1024,3)) as total_size from tables) as total_size_gb,
(select sum(INDEX_LENGTH)/(POW(1024,3)) as index_size from tables) as total_index_gb,
(select sum(DATA_LENGTH)/(POW(1024,3)) as data_size from tables) as total_data_gb, 

(select ((sum(INDEX_LENGTH) / ( sum(DATA_LENGTH) + sum(INDEX_LENGTH)))*100) as perc_index from tables) as perc_index,
(select ((sum(DATA_LENGTH) / ( sum(DATA_LENGTH) + sum(INDEX_LENGTH)))*100) as perc_data from tables) …

+2 Vote Up -0Vote Down

Let's take quick look at the performance of the new InfiniDB Subquery processing available with the 1.1.1 Alpha.  The arrow was added to be sure our timings weren't confused with the axis.



This was against a relatively small dataset, the Star Schema Benchmark with 6 million rows in the fact table.  A base query was run where the outer query...

Kontrollbase – revision 297 fixes Reporter-CLI “alert_22″ sub-routine
+0 Vote Up -0Vote Down

Quick note to let our users know that there was an XML tag closure error on the “alert_22″ subroutine in the “bin/kontroll-reporter-cli.pl” script. This does not affect the webapp portion of Kontrollbase – only reports generated via the command line reporter script. It is not a fatal error but will cause the XML file to […]

Kontrollbase – graph “no data to display” on new install has been fixed
+0 Vote Up -0Vote Down

If you have been wondering why the overview and graphs pages say “no data to display” on the graphs when you first install Kontrollbase, it’s because there’s no data in the database being returned from the queries that generate the graphs – this is because a new install has no data to graph. This has […]

Kontrollbase rev292 gets important UI layout fixes

However, it is an important one to speak about as it solves a former issue when running the application on a screen smaller than 1024px wide. While most users may not have noticed this since they have larger monitors it has been noticed [...]
