Over the last 4 years I have been working on the Database Health Monitor. I am about a week away from releasing Version 2, which will finally be out of the beta process. In preparation for the release I am sharing some of the history of this program.
In 2011 version 1 was released as a set of my favorite monitoring queries that had been formatted and made available through SSRS. As people started to try it out in late 2011 and early 2012, I quickly discovered that the process for distributing shared queries via SSRS reports wasn’t very easy for the people trying to use them. Many people quickly discovered the difficulty of installing these reports. The set of reports looked something like this.
There were 10 reports that were linked from the top panel in the SSRS user interface. Although SSRS has some great features, it was challenging to switch database connections and monitor multiple servers.
In April of 2012 I gave up on the concept of using SSRS reports, and converted all the queries into a windows application and started enhancing the program. In September of 2012, I finally had the Beta 1 release of Database Health Reports out. It was a bit rough in the beginning, but from 2012 to 2015 through a series of almost 20 beta releases labeled names like Beta 1, Beta 8.2, Beta 10.1, and so forth I kept enhancing the program. Here is an early screenshot of somewhere around Beta 1 or Beta 2.
Late in 2012 I release a new feature in the program called “Historic Reporting” which installs a small agent on a monitoring server and keeps track of wait stats, cpu, plan cache and other stats over time. This is logged to a small database that allows you to go back to a point in time and see what was happening on your SQL Server. So when it is Thursday afternoon and someone says “The database was really slow on Tuesday morning”, you have the ability to see what was running, and what was actually going on at the point it time is was reported to be slow.
In 2014 I stumbled a bit and lost interest. It didn’t seem like many people were interested in the program, until the beginning of October when the previous beta expired. Boy did I get a lot of email from people who wanted to use the program and could no longer use the program since the beta had expired and there was no new beta. This was the catalyst that got things going again. I quickly released another beta to keep these current user base happy, and moved on to adding more features, fixing bugs, and driving towards a completing version 2.0.
From October 2014 to June 2015 I added many new features, fixed bugs and made the program much more robust. I tried out some things like crowd funding, which turned out to not work so well. If you were one of those people who contributed to the total of $180 that I received from the crowd funding campaign, thank you. That wasn’t enough to fund the development through crowd funding, so I shifted gears, and decided to make it a free program available to the SQL Server Community to give back for everything I have learned from others.
After deciding to make this a free product, I worked through 2015 until now to get it ready for final release, and continued to improve the program with new reports, new icons, and overall improvements. When I say free, I really mean free.
New in the full (non beta) release of Version 2.
Some of the most recent additions that will be part of the Version 2 release include the following:
- Removed Beta 3 month expiration.
- Added the Database I/O overview panel.
- Added the I/O by database instance level report.
- Database overview reports on databases set to autoshrink.
- Added a check for those using Veeam backups. There is a configuration where the Veeam backup breaks the log restore chain. This is now shown in the errors and warnings page.
- Filtered snapshot backups from the backup restore chain.
- Backup report now differentiates copy only backups from normal backups.
- Added ctrl+a for select all on the historic query advisor.
- Fixed a bug in the log restore chain script in the backup report.
- Added the database CPU heat map to show the average CPU load hour by hour for the last 7 days.
- Added the instance level linked servers report to display linked servers.
My favorite of those is the CPU heat map, which allows you to see hot spots over the last week and to determine when your SQL Server is under the most CPU contention, or when it is the most idle. The report is called “CPU Load by Hour of Day” and looks like this.
With this report you can easily figure out where the most load is from OLTP, or ETL loads, or whatever may be causing a cpu load on your server. For each hour of the day you can see the average CPU load.
So stick around and be ready to try out the full release of version 2 in the next week after the long awaited 5 years of development. Enjoy.
