Charts and Stats
New Blockscout stats service
Stats page example
Blockscout provides a way to easily calculate and display chain-relevant charts and statistics. For example, it can calculate and display the number of blocks per day, the average block reward, or the number of active accounts per day.
Statistics are implemented using a separate microservice that is connected to the indexed blockscout database. The source code and full README.md for the service is available here: https://github.com/blockscout/blockscout-rs/tree/main/stats
On start, the service performs initial calculations for all charts. After that, each chart updates independently according to its
update_schedule.It’s better to run the service after blockscout has finished the indexing process. During indexing blockscout database contains partial information about the blockchain, so statistics may be inaccurate.
The stats service will try to use cache values for efficient chart recalculation. If you decide to run statistics during indexing, rerun the service with
STATS__FORCE_UPDATE_ON_START=true env variable once indexing is finished to perform a full update of all charts.Options including docker, docker-compose or building from source.

Two types of charts are available for the Charts and Stats Section,
Linecharts and Counter charts.Example line chart where the X axis is date, and the Y axis is some data.

Total number of accounts
Blockscout has a set of predefined charts, which can be enabled or disabled using
charts.toml file. Default charts config can be found here: https://github.com/blockscout/blockscout-rs/blob/main/stats/config/charts.tomlThis file can be used as a template. Customize by removing unnecessary or unrelated charts from
.toml file. For example, here is a configuration with only block-related statistics:[[counters]]
id = "totalBlocks"
title = "Total Blocks"
update_schedule = "0 0 */3 * * * *"
[[counters]]
id = "averageBlockTime"
title = "Average Block Time"
units = "s"
update_schedule = "0 0 15 * * * *"
[[lines.sections]]
id = "blocks"
title = "Blocks"
[[lines.sections.charts]]
id = "newBlocks"
title = "New blocks"
description = "New blocks number"
update_schedule = "0 0 8 * * * *"
drop_last_point = true
[[lines.sections.charts]]
id = "averageBlockSize"
title = "Average block size"
description = "Average size of blocks in bytes"
units = "Bytes"
update_schedule = "0 0 9 * * * *"
drop_last_point = true
[[lines.sections.charts]]
id = "averageBlockRewards"
title = "Average block rewards"
description = "Average amount of distributed reward in tokens per day"
units = "ETH"
update_schedule = "0 0 20 * * * *"
drop_last_point = true
