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

Please see opCharts Product Compatibility to see which Linux Distributions and MongoDB we support.

opCharts 4.2.3

We recommend NMIS9.2 and greater for this release.

Improvements

• Improved query performance for nodes panels when showed as a resource.
• New action in opcharts-cli setup-db, this updates opCharts indexes in MongoDB on install and can be manually run from the cli.
• Node topology now supports ipv6
• opcharts-cli act=import-subnets has improved debug logging, set debug=1 to see how its calculating subnets
• opcharts-cli act=clear-subnets removes all cached subnets in the database.
• Two new configuration items items to help change sizing of components

  • "opcharts_gui_default_component_size" this sets the components sizes across the application, excludes node detail view

    • Default is 210

  • Before this release the component size was hard coded as 280 and would cause certain components to render larger than desired
    
    • "opcharts_gui_nodes_detail_component_size" this changes the size of the components in the node detail view.
    • Default is 280
• Inventory view for concept interfaces shows enabled and disabled interfaces for collect.

Bug Fixes

• Fixed issue in opCharts where a large amount MongoDB connections were created and retained.

• Inventory search improvements
  • inventory.data.Description is now searchable in the GUI with iregex
  • inventory.data.ifSpeed is now searchable as a string match
• LLDP Improvements
  • If NMIS9 has LLDP neighbor in its inventory opCharts will use its currently polled neighbors interface to show utilization and metadata
• CDP Improvements
  • If NMIS9 has CDP neighbor in its inventory opCharts will use its currently polled neighbors interface to show utilization and metadata
• Improved the panels in Business Services including a new Monitored Services Panel
• If the Interface or Node Panel cannot find any performance or utilization data it will show "No Data" instead of rendering nothing

 30 Sept 2020.

Upgrade Notes

The new upcoming release of opCharts 4 will work on Opmantek's latest and fastest platform, however, the currently installed products are incompatible with this upgrade.

• You can now create custom charts on the Primary with poller datasets
• You can now search by regex in the node edit screen

Bug Fixes

• Node resources now references the model as a source of truth in what to show, if you remove an item from the model it will not display in opCharts.

• Removed Topn link from the menu for RBAC users as this did not work

opCharts 4.1.1

Released 3rd July 2020

Bug Fixes

Fixed issue with inventory where the toolbar to change inventory never appeared.

...

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

...

Released August 22th, 2019

Upgrade Notes

Bug Fixes

• Fixed issue in opCharts where a large amount MongoDB connections were created and retained.

...

opCharts 3.4.0 was released on 15 July 2020

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

Bug Fixes

Fixed issue when adding neighbors to node topology.

...

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

...

• Refreshed login screen for all OMK applications
• Improved node searching speed, set nmisx_db_cache_enable => 1 in opCommon to take advantage of this.
• Chart editor now supports negative number in the multiply field
• Stacked charts can now display min/max/avg values for the sum of the stack
• Caching of subnets has been improved to decrease the risk of the file being locked when it needs to be read.
• Updated systemd compatibility for Opmantek services, see more here.
• Updated the logrotate script for systemd

Bug Fixes

• Fixed issue with update-subnet-dependancy
• opCore Node editor was setting the wrong key for collect_snmp
• 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
• Fixed issue where monitored service graphs had no date-time value

...

• 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',

    • 'opcharts_map_link_color_normal' => '#ffd700',

    • 'opcharts_map_link_color_warn' => '#ffa500',

    • 'opcharts_map_link_color_error' => '#d9534f',

    • 'opcharts_map_link_color_up' => '#00FF00',

    • 'opcharts_map_link_color_down' => '#FF0000',

    • 'opcharts_map_link_color_uk' => '#999'

•  Updated opCharts interface plugin, This is now run after every node update.

•  New commands added to opcharts-cli to update the subnet dependencies: 

  • opcharts-cli.pl act=clear-all-node-depend: Clear all the nodes dependencies

  • opcharts-cli.pl act=update-subnet-dependancy: Update all the nodes subnet dependencies

  • New configuration items have been added:

  • 'opcharts_subnet_skip' => 'qr/(^127\.0\.0|^169.254\.|^192.168\.)/',

  • 'opcharts_router_names' => 'qr/^RTR/';

  • 'opcharts_router_skip' => 'qr/-router1$/'

• Added search box to interfaces in business service.
• Updated the opCharts.init.d service

Bug Fixes

• opCore node location editor now correctly renders the delete modal
• Expanded Menu drop downs are now clickable on mobile
• Fixed issue where sorting multiple times in quick succession or any page other than 1 will cause the sorting to produce unexpected results
• Fixed issue where custom group status in the panel would always show unreachable
