Rust Log Monitoring with LogMonitor

>_ why rust apps need log monitoring

Rust applications are known for reliability, but bugs in business logic, external API calls, and configuration still happen. When running Rust services in production, println! output gets lost and the tracing ecosystem requires infrastructure to collect logs. LogMonitor gives your Rust application a simple HTTP endpoint to stream structured logs to a Live Console.

>_ how logmonitor works with rust

Use the reqwest crate to send structured log data to the LogMonitor HTTP API. Create a helper function that serializes your log entry to JSON and posts it to https://api.logmonitor.io/v1/logs. The API returns 202 Accepted on success. The function integrates easily with Rust's standard error handling patterns.

>_ quick start

use reqwest::Client;

use serde_json::json;

use std::env;

use std::time::{SystemTime, UNIX_EPOCH};

pub async fn send_log(

    client: &Client, level: &str, message: &str,

) -> Result<(), reqwest::Error> {

    let api_key = env::var("LOGMONITOR_API_KEY").unwrap();

    let timestamp = SystemTime::now().duration_since(UNIX_EPOCH).unwrap().as_secs();

    client

        .post("https://api.logmonitor.io/v1/logs")

        .header("X-Logmonitor-Api-Key", &api_key)

        .header("Content-Type", "application/json")

        .json(&json!([{"level": level, "message": message, "clientTimestamp": timestamp}]))

        .send()

        .await?;

    // Returns 202 Accepted on success

    Ok(())

}

// Usage:

// send_log(&client, "error", "DB query failed").await?;

• $Runtime panics and unwrap failures
• $HTTP handler errors in Actix, Axum, or Rocket
• $Database connection and query errors
• $Async task failures and timeout errors
• $Serialization and deserialization errors
• $External API integration failures
