- Updated the `[Rain_Command]` section in `config.ini.example` to include support for snow alongside rain, improving the command's functionality. - Enhanced documentation for the rain command to reflect the new snow alias and clarify response behavior based on the selected keyword. - Added a new `collect_stats` option in the `[Stats_Command]` section, allowing stats collection to be enabled independently of the user-facing command, with updated documentation to explain its behavior. - Improved the web viewer documentation to clarify how stats are collected and displayed, ensuring users understand the configuration options.

# Data retention
|
||
|
||
The bot stores data in a SQLite database for the web viewer, stats, repeater management, and path routing. To limit database size, **data retention** controls how long rows are kept. Cleanup runs **daily** from the bot’s scheduler, so retention is enforced even when the standalone web viewer is not running.
|
||
|
||
## Configuration
|
||
|
||
All retention options live in the **`[Data_Retention]`** section of `config.ini`. Example (see `config.ini.example` for full comments):
|
||
|
||
```ini
|
||
[Data_Retention]
|
||
packet_stream_retention_days = 3
|
||
daily_stats_retention_days = 90
|
||
observed_paths_retention_days = 90
|
||
purging_log_retention_days = 90
|
||
mesh_connections_retention_days = 7
|
||
```
|
||
|
||
Stats tables (message_stats, command_stats, path_stats) use **`[Stats_Command]`** `data_retention_days` (default 7); the scheduler runs that cleanup daily as well. Stats are **collected** by default with **`collect_stats = true`** under `[Stats_Command]`, even if the user-facing `stats` chat command is disabled with `enabled = false`. Set **`collect_stats = false`** only if you want to stop writing those dashboard stats tables.
|
||
|
||
## Tables and defaults
|
||
|
||
| Table / data | Purpose | Default retention |
|
||
|--------------|---------|--------------------|
|
||
| **packet_stream** | Real-time packets, commands, routing in the web viewer; transmission_tracker repeat counts | 3 days |
|
||
| **daily_stats** | Daily repeater/advert stats | 90 days |
|
||
| **unique_advert_packets** | Unique packet hashes for advert stats | 90 days (same as daily_stats) |
|
||
| **observed_paths** | Path strings from adverts and messages | 90 days |
|
||
| **purging_log** | Audit trail for repeater purges | 90 days |
|
||
| **mesh_connections** | Path graph edges (in-memory + DB); should be ≥ Path_Command `graph_edge_expiration_days` | 7 days |
|
||
| **message_stats, command_stats, path_stats** | Stats command data | 7 days (`[Stats_Command]` `data_retention_days`) |
|
||
| **geocoding_cache, generic_cache** | Expired entries removed by scheduler | By expiry time |
|
||
|
||
Shorter retention (e.g. 2–3 days for `packet_stream`) is enough for the web viewer and transmission_tracker; longer retention is only needed if you want more history.
|
||
|
||
## How cleanup runs
|
||
|
||
1. The **scheduler** (in the main bot process) runs a single data-retention task on a **24-hour interval** after startup (the first run is not immediate on boot; it aligns with the nightly maintenance email cadence).
|
||
2. That task:
|
||
- Cleans **packet_stream** (via web viewer integration when enabled).
|
||
- Cleans **purging_log**, **daily_stats**, **unique_advert_packets**, and **observed_paths** (repeater manager).
|
||
- Cleans **message_stats**, **command_stats**, **path_stats** (stats command’s `cleanup_old_stats`).
|
||
- Removes expired rows from **geocoding_cache** and **generic_cache** (DB manager).
|
||
- Deletes old rows from **mesh_connections** (mesh graph).
|
||
|
||
So as long as the bot is running, the database is pruned on a schedule regardless of whether you run the standalone web viewer or the stats command.
|
||
|
||
**Log files** (`[Logging] log_file`, e.g. `meshcore_bot.log`) use rotating file logging: the bot rotates at 5 MB and keeps up to 3 backup files (same policy as the web viewer), so log disk use stays bounded.
