This is a brief overview of the major changes between opCharts releases.

...

Released 25th June 2020 as General Release

 This release requires updated licenses, please contact Opmantek Support to organise new licenses

Highlights

All OMK configuration are now JSON, the processes to convert from NMIS configuration files to JSON is performed by the installer, click here for more details about JSON Configuration..

...

• The Metrics and Health component has been extended to group by any node configuration property.
  • This is set in opCommon.nmis opcharts_metric_summarise_by, you need to define an array of hashes, with key and name

  •     {
          'key' => 'group',
          'name' => 'Group'
        },

  • If more than one selector is defined on the top left of the Metrics and Health component a dropdown is shown to change which confiuration item the nodes are grouped by.
  • Metrics and Health gauges are now rendered in one row which are scroll-able to the right.
  • Metrics and Health links now correctly affect the nodes filter when clicked.
  • Metrics and Health is now searchable on the currently selected column.
• New Event History component which utilizes the NMIS9 events DB
  • For this to work in opCharts you need to set keep_event_history => 'true' in NMIS9 Config.nmis
  • Consideration should be given to the volume of data on the pollers and Primary and how much event history will be kept, by default NMIS9 will keep 7 days of event history which is configured in Config.nmis/purge_event_after (7*86400), if having problems viewing event history, reduce the number of days and purge the data.
  • This component replaces the old tail log event viewer but if you want to use the old component change opcharts_db_event_history to 0 in opCommon.nmis
  • Currently websockets are not enabled, this component is set to refresh period
• Revised Events screen to utilize the new Event History component
• Fixed issue where adding a group to a map would cause the node selection modal to appear
• Fixed issue where the nodes interfaces panel which shows interfaces with oper status down would fail to render
• Fixed issue where the nodes interface component would incorrectly show certain interfaces
• Fixed issue where the node selector on the nodes screen will fail to render if a group name is numeric
• Fixed issue where the TopN table text would not correctly space the table contents
• Fixed issue where a node info panel would cause a 500 if the node does not exist

...

This release fixes a caching issue which caused high disk load when "nmisx_db_cache_enable" is set to true.

...

• Refreshed login screen for all OMK applications
• Improved node searching speed, set nmisx_db_cache_enable => 1 in opCommon to take advantage of this.

• Node editor logs the current user in the audit.log when node config is changed
• Fixed issue where the failure flash message was not displayed

...

• Newly created maps now use the nodes UUID, this allows maps to be created which will not degrade over time when nodes names are changed.

  • Maps created with opCharts-3.3.4 and below still use the nodes name as its ID, any changes or additions to these older maps will continue using the node name

• Nodes are now sortable by health

• Metrics and Health now shows the status metric

• Nodes view now uses case insensitive regex for searching.

• Changed the colours of the link between the nodes based in the input and output utilisation: 

  • < 30 = green, 

  • >=30 <75 = yellow, 

  • >=75 <100 = orange, 

  • >=100 = red

  • If the utilisation information is not available, the colour will be based in the status:

    • Green: up 

    • Red: Down

    • Grey: Unknown

  • This colour guide can be changed in the configuration, with the following configuration items:

    • 'opcharts_map_link_color_ok' => '#59cf59',
