Monyog MySQL Monitor v8.3.0: Introducing Trend Graph Analysis

Monyog MySQL Monitor v8.3.0 is a feature-rich release which adds a large number of user requests for quick access to relevant monitoring information, for ‘cross-plotting’ multiple servers in a unified chart and more.  Additionally, it adds a number of non-critical bug fixes.

Changes as compared to Monyog MySQL Monitor v8.2.0 include:

Features:

  • Added option to set a distinct email distribution list for warning alerts and critical alerts.
  • Trend Graph Analysis: Added option to group a single metric (which one you find most important) from different servers into one unified chart. This allows you to visually analyse a metric across servers at various points in time.

Choose the monitor group >> Click on the trend graph icon next to the metric as shown below.

Monitor single metric across servers

  • Added option for disk monitoring of the system where Monyog is installed. In case the free space on the system where Monyog is installed goes below a defined threshold value, Monyog will raise an alert.
  • Added a REGEX-based filter to exclude unwanted long_running queries in Sniffer. Monyog will ignore queries satisfying the expression and neither kill nor send an alert for such.

  • Added option to filter queries based on poor indexes, missing indexes, errors and warnings. This feature is available for PERFORMANCE SCHEMA based sniffer in Query Analyzer and “Show details” page in Dashboard. When you choose a filter, Monyog will show queries based on the criteria set.

  • Monyog showed the total time and average latency as “0” when the execution time of the query was less than a second for table based slow query log.
  • Fixed an issue with Custom SQL Object (CSO) – Monyog logged entries like “not an error” in MONyog.log.
  • Server name with ‘&’ in it was not getting deleted.
  • In some rare cases, Monyog failed to generate alert if the network connection on the machine where MySQL is running goes down.
