• New Remote Data component to get JSON data from other services and display on dashboards.

opCharts 4.0.9

Released October 31st, 2019

• New Remote Data component to get JSON data from other services and display on dashboards.
  • This can be used to show data from other Opmnatek Applications APIS using our token authentication on
  • Example widget showing weather from the Gold Coast included
  • Documentation on creating remote data widgets
• Fixed issue where clicking Full screen on a dashboard would fail to render.
• Event History, change in logic to show the event is displayed
• Fixed the Node api and versioned it to v2

opCharts 4.0.8 Beta

Released October 10th, 2019
opCharts 4.0.8 requires NMIS 9.0.8

• 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 master 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

opCharts 4.0.7A requires NMIS 9.0.6

• Fixed issue in the TopN Query where it would show no data for an nmis user

• Improved TopN Performance

  • If you do not have the latest NMIS9 add 'opcharts_optimized_topn_query' => 0 to opCommon

  • If you user has all groups you could be shown reduced topn results if a node was in the topN in the last 15 minutes and has since been removed.

• Fixed issue where Metrics and Health component on a dashboard would not scroll

• Fixed bug that was failing to check permissions for a subnet.

opCharts 4.0.7 Beta

Released August 22th, 2019
opCharts 4.0.7 requires NMIS 9.0.6

  • If you want to change which metric the gauge can display copy omk/lib/json/opCharts/components.d/nmis_network_health.json into omk/conf/components.d
    • change "gaugeDataSource" to one of the desired values
      • avg_available or avg_16_available
        
      • avg_health or avg_16_health

• Fixed issue where a node name is numeric fails to display in a geo map
• When you are shipping poller logs to the master these can be displayed for the node my changing the config option 'opcharts_event_log_type' => 'poller_event_log' 
  • These logs are expected to be in the default NMIS9 directory for logs <nmis_logs>/poller_event.log 
  • NOTE: refer to Config.nmis for your setting of <nmis_logs>, it defaults to /usr/local/nmis9/logs/
• If you wish to hide the event log widget for nodes you can set 'opcharts_gui_node_eventlog_display' => 'false'
• Fixed issue where 'auth_default_groups' => 'all' would not allow access to 'all' group
  • Set auth_default_groups & auth_default_privilege in opCommon to use this feature.

• Subnets are now cached in the background, this is done by a NMIS9 plugin on install/upgrade, or can be found under install as SubnetExport.pm
  • opcharts_subnet_cache_expire_time is how long they will live for
  • opcharts_subnet_cache_update_time is the minimum period the cache will run, as it happens after NMIS updates this stops the cache being run too frequently which can cause high load.
• Subnet cache can be manually run with the opCharts CLI, with act=import-subnets

opCharts 3.3.8

Released May 5th, 2020
opCharts 3.3.8 requires NMIS 8.6.2G

Bug Fixes

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

If you need to sort by node health in the nodes list while using DB caching you need to set "nmisx_db_cache_node_health_sorting" to true, this setting was introduced in 3.3.8 and is false by default.

When using opCharts as a Primary and with "nmisx_db_cache_enable" set to true, data in the nodes list, which is derived from a pollers node summary8h or summary16, cannot be displayed

opCharts 3.3.7

This was an internal release

• Nodes are now sortable by health

  • >=100 = red

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

    • Green: up 

    • Red: Down
