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 3.3.2

Released Dec 5, 2018
opCharts 3.3.2 requires NMIS 8.6.2G

Highlights

Metrics and Health component from NMIS can be added to a dashboard or be found under Views
Topological map rendering improvements
NMIS Locations and Groups are editable within opCore and opCharts under System.
New node editor which supports

SNMPv3 credentials
WMI credentials
Bulk updating of nodes
Editing of current nodes
Creation of new Nodes
Notes

Node collect is based on snmp_collect and wmi_collect, future NMIS versions will take these new flags into account.
Editing of nodes, locations and groups is editing the local NMIS config
Editing of nodes in opCore and opCharts updates opEvents and opConfig nodes collection if these products are installed, this is an always on behaviour
Creating or editing of nodes takes a couple of minutes to show up through opCharts

Outage Editor now supports node.host selector
File management is now able to delete files
Event log viewer has been rewritten for speed and usability
New config option to force WebSockets over a certain port, needed for secure WebSockets and Apache socket proxy

websocket_proxy_port under opCommon

Create a real-time graph when viewing an interface, this creates a new collector using the current interfaces snmp index

The default poller is a config option in opCommon.nmis opcharts_interface_graph_default_poller defaults to "Interface Utilisation - High Speed" on install

New colour for major events based on the NMIS8 major colour.
Certain node resources now prepend ifDescr
Node searching on all opCharts pages

Node searching uses AJAX, prefetching config option has been removed.

Go back button, when going between applications you can click the go-back button by the breadcrumbs
If a collector is collecting an interface its ifDescr will be shown in the collectors table.
When creating a new collector and the and the polling definition is for an interface you can quick search the selected nodes interfaces which will make it easier to find the snmp_index
Maps now have a button to refocus geo-maps

Fixes

Giving read dashboard permissions to an RBAC user would only give access for the first component.
Spanish translation updated
Nodes view and topn view wrongly showed filter button.
Dashboards other than the default can be shown again on the home screen
Improved robustness and reduced external dependencies

opCharts 3.3.0

Released Aug 15, 2018

opCharts 3.3.0 requires NMIS 8.6.2G

Highlights

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

opCharts 3.2.9

Released Jun 22, 2018

opCharts 3.2.9 requires NMIS 8.6.2G

Fixes

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.

opCharts 3.2.8

Released May 31, 2018

opCharts 3.2.8 requires NMIS 8.6.2G

Fixes

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

opCharts 3.2.7

Released May 3, 2018

opCharts 3.2.7 requires NMIS 8.6.2G

Highlights

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.

Fixes

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.

opCharts 3.2.6

Released March 14, 2018

opCharts 3.2.6 requires NMIS 8.6.2G

Highlights

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
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.

Fixes

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.

opCharts 3.2.5

opCharts 3.2.5 requires NMIS 8.6.2G

Highlights

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

Fixes

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