...

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
