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

Note: as of opCharts 3.0.0, MongoDB is required, the installer will help you install/upgrade to the newest 3.X version.

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

    • 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

    • 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'

    • Setting the 'nmis' users password
    • Base URL & Hostname
    • Mail Settings
    • Quick node editor for SNMP v1 & v2 devices (Editing of SNMPv3 devices should be done through the NMIS node tool)

opCharts 3.2.7 requires NMIS 8.6.2G


  • Added grid search box to node list, columns available for searching are controlled by opCharts_node-list.json
  • Dynamic geographical maps, nodes on map generated using a filter generated by node list view. From the node list view, select whatever filters desired, then click "View in geographical map", in the top right of the component there are now two options for creating a map from this view, "Create static map" and "Create dynamic map". The static map will use the current filter and save the list of nodes into the map, the dynamic map will save the filter into the map and the list of nodes will be generated each time the map is loaded. Note: a refresh of the map to get new status information will not add/remove nodes, a full page refresh is required to make this happen.
  • Geographic maps that have many nodes in the exact same spot will now fan them out when clicked so all nodes form that spot can be seen.
  • Adding a link to a network map or topographical map now allows selecting the line width and color.


  • Interfaces view was slow when there was a large number of interfaces, this was due to authorisation checks being done on more interfaces than were being viewed, this has been fixed.
  • When adding a new outage, the modal could take a long time to load/find nodes, this is now properly paginated and should be much faster
  • collector imports no longer require the collector being imported to have a name (they are stripped out of the definition when exporting, the name is auto-generated on creation so we have a quick human readable attribute when analysing data)
  • Adding a link to a Network map was broken, it is now fixed.

Released March 14, 2018

opCharts 3.2.6 requires NMIS 8.6.2G


  • Node list performance has been improved significantly and will be noticeable on systems with higher node counts, particularly on the node list page and on and scheduled outage page. Authorization checks were being done inefficiently, this has been fixed. NMISx db caching is now the faster option, by default this config item is turned off, change nmisx_db_cache_enable to 1 to enable. Ability to sort by node health has been removed.
  • Performance of custom group status calculations has also been significantly improved, making maps with many custom groups load significantly faster.

  • Auto geographical maps available from a link on the Node list page, the Nodes location is taken from either it's Nodes.nmis entry or the lat/long in it's Location table entry, the Nodes.nmis fields names are location_latitude and location_longitude
  • Geographical maps will cluster items on the map that are too close together, set opcharts_maps_geographical_clustering to 0 to disable this feature
  • File Uploads, Map Icons and Backgrounds can now be uploaded through the web interface.
  • Collapsible Sidebar, below the sidebar, is a button to toggle the sidebar to be open or closed.
  • Improved Dashboard editing; While editing dashboards elements can be moved around by dragging its header and sizes changed by pulling the components bottom right corner.


  • Resource lock bug when editing maps, if any resource was being edited the map could not be saved saying the lock had been stolen.

  • TopN exporter can have sparkline data export disabled using opcharts_topn_include_sparklines
  • TopN exporter now writes a pid file to /tmp and only allows one TopN export process to run at a time


  • Subnet cache was not being invalidated/recalculated properly, it is now. This means auto-toplogy maps should show more complete and connected subnets.
