To find out more about this upgrade please read: Upgrading Opmantek Applications

opCharts 3.4.0 was released on 15 July 2020

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

Fixed issue when adding neighbors to node topology.

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

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

This was an internal release

Released November 29th, 2019
opCharts 3.3.6 requires NMIS 8.6.2G

• 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

• 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

Released September 24, 2019
opCharts 3.3.5 requires NMIS 8.6.2G

• 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-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$/'

Released Aug 15, 2018

opCharts 3.3.0 requires NMIS 8.6.2G

• New getting started wizard. For getting opCharts, NMIS and our other Opmantek applications going faster we have introduced a new wizard help guide you through the initial steps of a new installation.

  • 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)

• The getting started wizard pushes settings out to the local NMIS8 Installation if required, this happens when the base_url and hostname inside opCommon and NMIS8 config match.

• Any config changes made through the node quick node editor and general settings will version the file, these can be found in /usr/local/nmis8/backups and /usr/local/omk/backups respectively. Versioned files follow the name configname.extension.version these increment from the last highest version. 50 versions of a config file will be kept, this can be configured in opCommon find the key max_backup_files

• omk_backup key inside opCommon can be used to change where omk versioned config files are kept

• The new editor can be found on the app landing page /omk

Released Jun 22, 2018

opCharts 3.2.9 requires NMIS 8.6.2G

• Node list sorting was broken for all columns except node name

• Stacks in NMIS graphs would report value of 0 instead of null when no value should have been displayed

• Network Maps with links would not load properly.

Released May 31, 2018

opCharts 3.2.8 requires NMIS 8.6.2G

• Memory leak introduced into common DataController component in opCharts 3.2.6

• Subnet cache not being used correctly and causing it to be refreshed on every access

Released May 3, 2018

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.

• Scheduled Outages now requires at least one value for it to be created, throws a validation error if the form is not completed.

• Dashboard chart components are now responsive to the width of the browser window.

Released January 24, 2018

opCharts 3.2.5 requires NMIS 8.6.2G

• RBAC users can now have default dashboards, setting them from the dashboard or from their preferences page, administrators can set default dashboards for all users.  Defaults for all users can be set using the user 'skel_user' in UserPreferences.nmis

• Topology Maps: When adding subnets automatically add all nodes in point-to-point subnets

• 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.
