...

• Metrics and Health Component now works for RBAC users.
• You can now create custom charts on the master Primary with poller datasets
• You can now search by regex in the node edit screen

...

• 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 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

Released August 22th, 2019
opCharts 4.0.7 requires NMIS 9.0.6

• Fix TopN query error in master Primary servers with lots of data from the poller servers. The error was a MongoDB::DatabaseError: operation exceeded time limit.
• New Admin function to set many user's default dashboard:

  • ./opcharts-cli.pl act=import-user-dashboard name=dashboard-name users='user1, user2, ...'

• Fixed changing the default dashboard for a user in the GUI. 
• NMIS button works for non local servers now: Redirects to the NMIS node poller view. 
• GUI improvements:
  • Fixed size in NMIS button (Nodes View) and set visible as default.
  • Improve view for long group names in Metrics and Health view, not overflowing.
  • Improve the view for long names in TopN table.
• Support for watching monitored services graphs from the poller servers in the masterPrimary. 
• Fixed bug that prevented hiding ssh button in node info panel where it was disabled using opcharts_gui_display_node_ssh.
• Fixed bug that was failing to check permissions for a subnet.

...

• Metrics and Health component has been rewritten to support Master Primary and Poller, this is done over the whole active nodes collection on the current server.
  • When you have nodes from different pollers Gauges are used to shows the current groups Reachability
  • 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
        
      • avg_reachable or avg_16_reachable
        
      • metric or metric_16
        
      • status
    • Change "gaugeTitle" to a desired title
  • In poller mode where only the current polled nodes are on the server Metrics and Health will show the current NMIS Network Health chart
• Added "websocket_proxy_port" to opCommon, this can be used to override which port the web client should connect its web-socket to.
• Node searching has been rewritten, now much faster.
  • You can search over the nodes
    • Name
    • Host
    • Group
• Fixed issue where the Node list could not be exported to csv. Use opcharts_node_list_exporttocsv to configure which fields to export
• Fixed issue where some pages would not resize correctly when hiding the sidebar
• Fixed node panels KPI colouring by level.
• View node on local NMIS now correctly uses the nmis9 URL defined in opCommon
• Added View Nodes on poller, more can be found Here

...

• Fixed issue where a node name is numeric fails to display in a geo map
• When you are shipping poller logs to the master Primary 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.
• Monitored services: This view will show monitored services from the poller nodes. 
• Bug fix to show IP address and mask on inventory and interface list. 
• Node panels now correctly show Health Kpi and Response Time
• In an MSP environment and wish to hide popup notification errors to users bar users with administrator privileged use 'omk_gui_show_user_errors' => 'false'
