1.1.1 [2024-11-26]

Bugfixes

• Fixed a backward compatibility issue with custom health status labels: previously, if customized health status labels (OPENWISP_MONITORING_HEALTH_STATUS_LABELS) were used and the new "deactivated" status label was missing after an upgrade, the application would crash during startup. In this version, a default set of valid labels is always available, which is then overridden by custom labels as needed.

• Introduced default timeouts for Celery tasks.
• Renamed the "Uptime" chart to "Ping Success Rate."

Dependencies

• Bumped openwisp-controller~=1.1.0
• Bumped influxdb~=5.3.2
• Bumped django-nested-admin~=4.0.2
• Bumped python-dateutil>=2.7.0,<3.0.0

• Used the "time" argument for calculating time in Chart._get_time.

1.0.4 [2023-01-24]

Bugfixes

• Allow additional properties on wifi/mobile signal. This will help to reduce backward compatibility issues when new properties are added to the monitoring agent.

1.0.3 [2022-12-29]

Bugfixes

• Fixed data collection for missing mobile signal: Skip writing mobile signal metric if mobile signal info is missing.
• Fixed device health status changing to problem when the configuration status changes to modified.

1.0.2 [2022-08-04]

Bugfixes

• Fixed migrations which create checks for existing devices;
  this problem was happening to OpenWISP instances which were
  deployed without OpenWISP Monitoring and then enabled
  the monitoring features

1.0.1 [2022-07-01]

Bugfixes

• Removed hardcoded static URLs which created issues when static files
  are served using an external service (e.g. S3 storage buckets)
• Fixed "migrate_timeseries" command stalling when measurements
  exceeds retention policy

1.0.0 [2022-05-05]

Features

• Added metrics for mobile (5G/LTE/UMTS/GSM) signal strength,
  signal quality and mobile access technology in use.
• Made Ping check configurable
• Added monitoring status chart to the dashboard and a geographic map
  which shows a visual representation of the monitoring the status of
  the devices.
• Added functionality to automatically clear the device's
  management_ip when a device goes offline
• Added support for specifying the time for received time-series data.
• Made read requests to timeseries DB resilient to failures

Changes

Backward incompatible changes

• Monitoring Template is removed in favour of openwisp monitoring
  packages. Follow the migration guide in migrating from
  monitoring scripts to monitoring packages section of
  openwisp-monitoring documentation.

• If you have made changes to the default Monitoring Template, then
  create a backup of your template before running migrations. Running
  migrations will make changes to the default Monitoring Template.

• The time-series database schema for storing interface traffic
  and associated WiFi clients has been updated. The data for
  interface traffic and associated WiFi clients is stored in
  traffic and wifi_clients measurements respectively. The Django
  migrations will perform the necessary operations in the time-series
  database aysnchronously. It is recommended that you backup the
  time-series database before running the migrations.

  You can use the migrate_timeseries management command to trigger
  the migration of the time-series database.

• The interface traffic and associated WiFi clients metrics
  store additional tags, i.e. organization_id, location_id and
  floorplan_id.

Dependencies

• Dropped support for Python 3.6
• Dropped support for Django 2.2
• Added support for Python 3.8 and 3.9
• Added support for Django 3.2 and 4.0
• Upgraded openwisp-controller to 1.0.x
• Upgraded inflxudb to 5.3.x
• Upgraded django-cache-memoize to 0.1.0
• Upgraded django-nested-admin to 3.4.0

Other changes

• Configuration applied check is triggered whenever the
  configuration status of a device changes
• Added a default 5 minutes tolerance to CPU and memory alert
  settings.
• Increased threshold value for disk alert settings from 80% to
  90%, since some device models have limited flash and would trigger
  the alert in many cases.
• Renamed Check.check field to Check.check_type
• Made metric health status independent of AlertSetting tolerance.
  Added tolerance_crossed parameter in
  openwisp_monitoring.monitoring.signals.threshold_crossed signal
• The system does not sends connection notifications if the
  connectivity of the device changes
• Improved UX of device's reachability (ping) chart. Added more
  colours to represent different scenarios
• Avoid showing charts which have empty data in the REST API response
  and in the device charts admin page

Bugfixes

• Fixed a bug that caused inconsistency in the order of chart summary
  values
• Fixed bugs in restoring deleted devices using django-reversion
• Fixed migrations referencing non-swappable OpenWISP modules that
  broke OpenWISP's extensibility
• Skip retry for writing metrics beyond retention policy. The celery
  worker kept on retrying writing data to InfluxDB even when the data
  points crossed the retention policy of InfluxDB. This led to
  accumulation of such tasks which overloaded the celery workers.

0.1.0 [2021-01-31]

First release.
