* Set the range using `prerun.start` and `prerun.stop`. Use `prerun.ranges` if prerun on more than one range is required.
|
||||
* Currently, `prerun.params.includeTD` must be set to `true`.
|
||||
|
||||
## Monitoring
|
||||
|
||||
* Enable metrics using config parameters `prom.metrics` and `prom.http`.
|
||||
* `eth-statediff-service` exposes following prometheus metrics at `/metrics` endpoint:
|
||||
* `ranges_queued`: Number of range requests currently queued.
|
||||
* `loaded_height`: The last block that was loaded for processing.
|
||||
* `processed_height`: The last block that was processed.
|
||||
* `stats.t_block_load`: Block loading time.
|
||||
* `stats.t_block_processing`: Block (header, uncles, txs, rcts, tx trie, rct trie) processing time.
|
||||
* `stats.t_state_processing`: State (state trie, storage tries, and code) processing time.
|
||||
* `stats.t_postgres_tx_commit`: Postgres tx commit time.
|
||||
* `http.count`: HTTP request count.
|
||||
* `http.duration`: HTTP request duration.
|
||||
* `ipc.count`: Unix socket connection count.
|
||||
|
||||
## Tests
|
||||
|
||||
* Run unit tests:
|
||||
|
||||
```bash
|
||||
make test
|

```
|
||||
|

## Import output data in file mode into a database
|
||||
|
||||
* When `eth-statediff-service` is run in file mode (`database.type`) the output is in form of a SQL file or multiple CSV files.
|
||||
|
||||
* Assuming the output files are located in `./output_dir` directory, if the DB is running in docker we need to mount the directory containing the files as a volume in the DB service. Eg:
|
||||
* Assuming the output files are located in host's `./output_dir` directory.
|
||||
|
||||
```yaml
|
||||
# In docker-compose file
|
||||
services:
|
||||
ipld-eth-db:
|
||||
volumes:
|
||||
- ./output_dir:/output_dir
|
||||
```
|
||||
|
||||
* Start `bash` in the DB container to run import commands:
|
||||
* Create a directory to store post-processed output:
|
||||
|
||||
```bash
|
||||
docker exec -it <CONTAINER_ID> bash
|
||||
mkdir -p output_dir/processed_output

|

* NOTE: `COPY` command on CSVs inserts empty strings as `NULL` in the DB. Passing `FORCE_NOT_NULL <COLUMN_NAME>` forces it to insert empty strings instead. This is required to maintain compatibility of the imported statediff data with the data generated in `postgres` mode. Reference: https://www.postgresql.org/docs/14/sql-copy.html
