Go Log Monitoring with LogMonitor
>_ why go apps need log monitoring
Go services are often long-running, high-throughput systems where a single goroutine panic can be hard to trace. Standard log output goes to stderr and gets lost in container orchestrators or systemd journals. LogMonitor captures structured logs from your Go application and streams them to a Live Console where you can filter, search, and debug in real time.
>_ how logmonitor works with go
Use the LogMonitor HTTP API to send structured log data from your Go application. Create a simple helper function that posts JSON to https://api.logmonitor.io/v1/logs. The API returns 202 Accepted on success. The function can be called from anywhere in your codebase and integrates with Go's standard log package or structured logging libraries like zerolog or zap.
>_ quick start
package logmonitorimport ( "bytes" "encoding/json" "net/http" "os" "time")var apiKey = os.Getenv("LOGMONITOR_API_KEY")func SendLog(level, message string) error { payload, _ := json.Marshal([]map[string]interface{}{ {"level": level, "message": message, "clientTimestamp": time.Now().Unix()}, }) req, _ := http.NewRequest("POST", "https://api.logmonitor.io/v1/logs", bytes.NewBuffer(payload)) req.Header.Set("X-Logmonitor-Api-Key", apiKey) req.Header.Set("Content-Type", "application/json") _, err := http.DefaultClient.Do(req) // Returns 202 Accepted on success return err}// Usage:// logmonitor.SendLog("error", "Request failed")>_ what you can monitor
- $HTTP handler errors and panics
- $gRPC call failures and deadlines exceeded
- $Database connection pool exhaustion
- $Goroutine panics and deadlocks
- $External service call timeouts
- $Configuration and startup errors
>_ frequently asked questions
LogMonitor currently provides native SDKs for JavaScript and Flutter. For Go, you use the HTTP API which is straightforward to call with Go's standard net/http package. A helper function takes about 15 lines of code.
Yes. Wrap the SendLog function in a goroutine or use a channel-based log queue to send logs without blocking your request handlers. This ensures zero overhead on your hot paths.
Yes. You can create a custom writer or hook for zerolog, zap, or logrus that calls the LogMonitor HTTP API. This way your existing structured logging calls are automatically forwarded.
Yes. Each microservice can use the same or different app IDs. Include service name, request ID, and trace ID in the metadata to correlate logs across services in the LogMonitor dashboard.
The HTTP POST to the LogMonitor API typically completes in under 50ms. For high-throughput services, batch logs or send them asynchronously to avoid any impact on request latency.
