ogamma Visual Logger for OPC - Release Notes.

Known issues.

  1. When InfluxDB time-series data is used to store data, and value in the field Database specific settings/json, property precision value is set to either us (for microsecond) or ns (for nanosecond), data is written, but cannot be read back. It seems that the issue is on the InfluxDb side: it works fine in the instance of InfluxDB hosted by InfluxData but does not work with Docker image version quay.io/influxdb/influxdb:2.0.0-beta.
  2. When the Refresh Data field in the Logged Variables table is set to automatic refresh mode, it is not possible to edit records in that table. The workaround is to turn data refreshing off before editing records.
  3. Table Logged Variables has too many columns and not all of them fit well into the screen, and horizontal scrolling is not available, which causes problems viewing/editing them. Workaround: Use the "Column Chooser`` button in the right top corner of the table and select columns that need to be visible or hidden (usually not all columns need to be visible).
  4. When OPC UA Server connection settings or logged variables settings are changed, to apply them, connections to all OPC UA Servers are closed and re-opened, and subscriptions and monitored items are re-created. When an application instance has a large number of server connections and logged variables, this might be inconvenient.
  5. When communication with the time-series database is slow or broken, and there are Grafana sessions querying data via ogamma Visual Logger for OPC REST endpoint, this can cause issues with configuration GUI responsiveness. As a workaround, a separate instance can be created to serve the REST endpoint or the number of threads in the same instance can be increased (option Web Server Settings / Number of threads in the Instance Settings dialog window).
  6. Reading of historical data from an Apache Kafka-type database ( processing of Grafana requests) can be slow when within the requested time range there are large numbers of records for variables with the same topic and partition as topic and partition for the variable for which data is being requested. The reason for this is that although they might have different keys, it is not possible to filter records by a key value, they are filtered in Kafka broker only by topic name and partition. So records for multiple keys are read, and then from them, records with the desired key value are selected, which takes considerable time.
  7. If the configuration database is not available at start-up, then the configuration GUI is not accessible. This issue exists in versions starting from 2.1.16.
  8. When a server node is added/removed/modified in the Address Space panel it might become empty although there must be some server nodes. In such case, the web page needs to be refreshed to view all the servers.
  9. Grafana endpoint is not compatible with the newest version of Grafana anymore.
