Crate ftdc 

Download mongodb FTDC data

Crate to enable your application to download FTDC data from mongodb clusters to investigate deeper (e.g. keyhole (https://github.com/simagix/keyhole)).

Usage

To download FTDC data from a mongodb cluster you need to provide some input to the CLI:

1. Group key: The group key (or: project id) the respective cluster belongs too. It is encoded into the link you get from atlas when selecting the specific cluster on Atlas UI (e.g.cloud.mongodb.com/v2/{group key}clusters)
2. Replicaset name: The name of the replica set the data should be loaded from. You can either provide the direct targeted replica set name (e.g. atlas-<something>-shard-0) or the name of the shard (e.g some-name-shard-00). Do not forget the number here as it qualifies the shard in case you want data from a sharded cluster. For a standalone replica set it is00 but lets say for a sharded cluster with 3 shards it would be 00, 01, 02.
3. API key: You need to have a valid API key for at least the cluster you want to download FTDC data from.

Example

use error::Error;
use reqwest::Client;
use service::{FtdcDataService, FtdcLoader};

#[tokio::main]
async fn main() -> Result<(), Error> {
  let group_key = "...";
  let replica_set_name = "...";
  let size = 10_000_000
  let atlas_public_key = "...";
  let atlas_private_key = "...";

  let service = FtdcDataService::new(Client::new());

  service
    .get_ftdc_data(
      group_key,
      replica_set_name,
      size,
      atlas_public_key,
      atlas_private_key,
    )
    .await
    .map(|download_path| println!("Downloaded to: `{download_path}`"))
}

The data is downloaded to the current directory the application was executed in as a *.tar.gz.
