Druid New Console Changes

**Changes**

**Main Page**
The old console displayed historical nodes count by Tiers, the new one only shows total. It's helpful to know by Tiering

**DataSource Tab**

- Could have shown hot tier and cold tier period highlighted on the timeline
- The period filter on the timeline is limited up to 1 year, can we have an option to show it for full-time rage or selected time range
- Also would be better if total size for the segment set as default instead of segment count
- In legacy, we had an option to download daily/ monthly summary unreplicated

**Servers Tab**

- It would be useful if the average disk usage for each node type is mentioned.
- In legacy coordinator console, historicals has the avg disk usage for each tier, it was really helpful

**Segments tab**

- When looking for a date in the segment, it lists down all the partitions for a day with size for each, but to get overall size had to go back to Datasource tab, whereas as in legacy it's not so
- Also, each partition of the date should show the info on no of dimensions and metrics available and its list

the legacy console had all of the features above and mostly used to that, would be helpful if we get these on new druid console

Review the requested differences across the new console's Main Page, DataSource, Servers, and Segments tabs, comparing them with the legacy console behavior described in the issue. The work is complete only when the requested tier, timeline, summary, disk-usage, segment-size, and partition metadata capabilities are defined and implemented.
