Gateway Hub 2.0.0
Released: 8 April 2020
This release delivers the updated binaries for Gateway Hub in the ITRS Downloads page.
Note: Upgrading from Gateway Hub 1.x.x to 2.0.0 is not currently supported.
Highlights
These are the highlights of this release:
- Dashboards
- Metric query improvements
- Reduced hardware requirements
- Centralised configuration UI
Dashboards
The Web Console now includes Dashboard functionality for easy visualisation of metrics and their related events. This release includes line charts, bar charts, KPIs, and table visualisations.
Metric query improvements
Metric storage and query performance has been improved. Queries that previously took up to a minute now take a few seconds or less. This is due to a change in the way that metric data is being stored, as well as various improvements to how metric data is being retrieved.
Reduced hardware requirements
Another benefit of improved query performance is reduced hardware required to run the Gateway Hub. The minimum memory requirements have decreased from 32 GB to 16 GB, and the disk space required for storage has also decreased.
The Gateway Hub sizing tool has been updated to account for these new minimums, although it is important to note that just like with all software, better hardware will result in better performance.
Centralised configuration UI
A new administration UI is provided for centralised configuration. Although the Gateway Setup Editor is still the best place to work with include files directly, the new Web Console pages provide some additional tools such as the ability to see which Gateways are using which includes and vice versa. It also provides the ability to see the history of include files, including the diffs between versions, as well as a UI tool to upload Gateway binaries to Gateway Hub, which is required for centralised setup validation.
New features and enhancements

|---|---|
| STARK-13034 | Added a View in Dashboard control to the Events viewer, allowing the current entity date filters to be passed to a dashboard. |

| STARK-12454 | A tooltip has been added to the Events overlay in metric history charts. |
| STARK-12419 |
Additional pre-install checks were added:
|
| STARK-12295 | Entities that have been grouped by severity are now displayed in decreasing order of severity instead of by count. |
| STARK-12117 | A legend has been added to the Events chart in the Web Console. |
| STARK-11134 | Creation time was added to the Events result table in the Web Console. |

STARK-13180 |
For large scale deployments, the Gateway Hub 2.0.0 installer can set PostgreSQL These values are found in the When these values are too small the Hub will perform poorly for both ingesting and querying metric data. You will also see entries like the following in the PostgreSQL logs at 2020-04-07 09:08:35.566 UTC [26000] LOG: checkpoints are occurring too frequently (1 second apart). 2020-04-07 09:08:35.566 UTC [26000] HINT: consider increasing the configuration parameter To resolve the situation, do the following on each Hub node after installation:

STARK-6505 |
Gateway Hub will not correctly handle a dataview defined in a Gateway with columns
named sampleTime, netprobeTime, or
dataViewId. |
