    MONyog MySQL Monitor 6.32 Has Been Released

  • peter_laursen
  • July 16th, 2015
  • MONyog, Releases
  • Important notice: With this release we have changed registration keys. Please have your  new key available when upgrading. As always you will get it from our Customer Portal.

    Changes (as compared to 6.31) include:

    Features:

    * Added a “Free Disk Space” Monitor for Linux. This new feature will collect information directly from the file system (unlike the existing ‘Disk Info’ that uses MySQL “SHOW TABLE STATUS”). Information is collected from volumes storing both MySQL data directory and InnoDB data directory (if different), and user will be alerted if either crosses a specified threshold.
    * In Charts page added an option to select a time interval for display by zooming a chart using mouse and similar input devices (touchpad etc.). Note that zooming one chart will change the timeframe of all the charts displayed.
    * Added an option to view queries for a selected time range in time range based charts in Charts page.

    Bug Fixes:

    * In rare cases, Monitors page could show wrong data for Linux counters if the HISTORY timeframe was selected for the page.  Other available timeframes were not affected.
    * When monitoring a MariaDB server using a galera-based replication setup we will now execute SHOW ALL SLAVES STATUS rather than just SHOW SLAVE STATUS. Before this MONyog replication page showed an empty result and alerts were not sent. However due to limitations with current MONyog architecture we are only able to handle the first row of SHOW ALL SLAVES STATUS with this release, if more are returned, and only information from one slave node will be available.

  • peter_laursen
  • June 25th, 2015
  • MONyog, Releases
  • Changes (as compared to 6.3) include:

    Features:
    * What is plotted in “Charts” (formerly “Dashboard”) page may now be specified as a time interval and not only as a number of latest sample points. This increases usability of the page.
    * Long running query log now includes action (kill/notify/notify and kill) and the time of action.
    * Locked and locking queries tab in Real-Time interface is optimized and loads faster.
    * Added w    ildcard filtering using the “*” character as wildcard for user and host in Query Analyzer for Slow Query Log.

    Bug Fixes:
    * MONyog failed to send notification for an InnoDB deadlock if deadlock details (as recorded by SHOW ENGINE INNODB STATUS) contained double quotes.

  • peter_laursen
  • May 20th, 2015
  • MONyog, Releases
  • Changes (as compared to 6.27) include:

    Features:
    * a log of long running queries can now be generated and downloaded as CSV in Sniffer interface (applies only to Processlist mode of sniffer).

    * Wayback Machine now includes user and host information as well.
    * Queries in Wayback Machine can now be exported as CSV.
    * MONyog can now send long running query notification to specific selected users only.
    * Wildcard filtering using the “*” character as wildcard for user and host is introduced in Sniffer (applies only to Processlist mode of sniffer).

    * MONyog now logs which user killed a thread in Processlist tab.
    * SQLite library bundled in MONyog is now upgraded to the latest version. This results in performance improvement for sniffer in particular where it can be up to ~50%.

    SQLyog MySQL GUI 12.12 Released

  • peter_laursen
  • May 19th, 2015
  • Releases, SQLyog
  • Changes as compared to 12.11 include: 

    Features:
    * XML files can now be imported from GUI controls in table menu/context menu provided that details of the XML follows one of the three supported XML-schemes supported by MySQL LOAD DATA XML syntax. This includes XML files generated with SQLyog and mysqldump.

    Bug fixes:
    * Server name in object browser was displaying wrong in some cases.
    * JSON export added in version 12.11 could add an extra delimiter what could cause an error in the environment where the JSON was used.
    * Profiler tab was getting focus instead of Messages tab in some cases if query was executed by placing cursor inside query and if more queries appeared in the Query tab and queries were executed ‘one by one’ (it did not happen when highlighting the query).
    * In ‘Export as’ dialog, SQLyog did not remember the escape character used if escape character was defined as “\\”. It would then replace “\\” with “\”.
    * In some cases SQLyog wasn’t displaying warnings for the query executed. Most common case was when a function was used with an argument of incorrect type causing server-side truncation of the argument (example: “SELECT ABS(‘a’);”)

    Miscellaneous:
    * Increased the dialog and column sizes for index and foreign key popup dialogs for better usability.

    Rockstar DBA: An Interview with Manojit Paul

  • Karthik Suroju
  • April 30th, 2015
  • MONyog, MySQL, Rockstar DBA
  • Rockstardba
    This article is a part of our Rockstar DBA initiative, a platform for thought leaders to share their knowledge and make a positive contribution towards the database management community.

    Manojit Paul, with more than 19 years of professional DBA experience in enterprise database solutions, especially Sybase product set and database infrastructure is our first Rockstar DBA.

    Let’s hear from Manojit about how he manages MySQL databases, why he loves MONyog, his advice to young DBA’s and more.

    How do you manage your MySQL databases?
    We presently have 9 MySQL servers in production trading environment, all being managed via a host of automated scripts which I’ve created and manual intervention when issues are reported. We deploy MONyog for managing 5 of these critical MySQL instances.

    What are your biggest challenges when dealing with MySQL databases?
    MySQL is not real enterprise class (evident from Gartner Reports omissions) and the rest of our database infrastructure relies on Sybase ASE and replication platform used for actual trading and logistics. We do have selective schema replication in MySQL but lack of proper scaling and optimization is a challenge.

    How does MONyog help you? What’s your favorite feature?
    We deploy MONyog for the MySQL monitoring and its web based dashboard helps with quicker problem identification and resolution. What I really like about MONyog is the dashboard with real-time statistics along with the charts displaying the overall performance metrics.

    Do you use other tools to manage your MySQL servers?
    We do not use any other MySQL related tools except the dbadmin scripts I have written.

    According to you, what is the future of MySQL?
    I want MySQL to compete with Percona/MariaDB and keep up with the feature sets that are still missing, like object level replication and online database backups and more support for the community version too.

    What blogs/forums/magazines do you follow regularly?
    Gartner reports related to database technology
    DatabaseJournal
    DBTA
    SQLMAG
    ISUG (sybase)

    What advice can you offer to young enthusiasts who want to pursue a career as DBA?
    I personally follow these basic rules. Not sure who gave these to me, they are helping me all along my professional life.

    1. Assume nothing
    2. Have contingencies
    3. Simplify
    4. Plan and Execute with precision
    5. Strive for Zero Defect work

    We are thankful to Manojit Paul for sharing his thoughts with us. We would love to hear your feedback as comments about our Rockstar DBA initiative.

    Sharing is caring. If you are a DBA who has something significant to offer to the community, we welcome you to be our next Rockstar DBA. Just send an email to us at support@webyog.com

    SQLyog MySQL GUI 12.11 Released

  • peter_laursen
  • April 27th, 2015
  • Releases, SQLyog
  • Important notes: .
    This release requires that user re-enters his registration key. Please have it available when upgrading. The key itself is the same as used by previous 12.x versions.
    * This release includes a new HTTP tunneler script. Functions deprecated in recent PHP versions are not used anymore and the script now also follows PHP strict standards. Users using HTTP tunnel must replace the script on their server(s).

    Other changes as compared to 12.1 include: 

    Features:
    * Added option to export table data and result sets as JSON.

    Bug fixes:
    * On Windows systems using a recent wininet.dll, setting the HTTP timeout higher than 30 seconds had no effect and SQLyog would fire same query 3 times if HTTP tunneling was used and query executed on server for more than 30 seconds.
    * Fixed a performance regression with “execute SQL script”.

    Miscellaneous:
    The new icons and other graphics introduced in 12.1 now have slightly darker and brighter colors.  As a result the UI is now ‘less pastel’ than before.
    Changes in 12.1 to the ‘twilight’ theme (default before 12.1) have mostly been reverted due to user requests.
    * Visual Data Compare UI now has the same 12.1 -style overall look as the main program window etc. has.

    SQLite  was updated to version 3.8.8.3. This will result in performance enhancement of up to 80% for Autocomplete with large local SQLite databases.
