Kubernetes Log Monitoring with LogMonitor

>_ why kubernetes apps need log monitoring

Kubernetes clusters run dozens or hundreds of pods across multiple nodes, making kubectl logs impractical for production debugging. Pods get rescheduled, scaled, and terminated constantly, and their logs vanish with them. LogMonitor provides a centralized Live Console that captures logs from every pod in real time, regardless of cluster churn.

>_ how logmonitor works with kubernetes

Integrate the LogMonitor HTTP API into your application code running inside Kubernetes pods. Send structured logs via HTTP POST and they appear instantly in your Live Console. The API returns 202 Accepted on success. You can also use a sidecar container pattern to forward stdout logs from legacy applications that cannot be modified.

>_ quick start

main.go · go
package main
import (
	"bytes"
	"encoding/json"
	"net/http"
	"os"
	"time"
)
func sendLog(level, message string) {
	body, _ := 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(body))
	req.Header.Set("X-Logmonitor-Api-Key", os.Getenv("LOGMONITOR_API_KEY"))
	req.Header.Set("Content-Type", "application/json")
	http.DefaultClient.Do(req)
	// Returns 202 Accepted on success
}

>_ what you can monitor

  • $Pod startup failures and CrashLoopBackOff errors
  • $Application-level errors across all replicas
  • $Inter-service communication and gRPC errors
  • $Resource limit warnings and OOMKill events
  • $Deployment rollout progress and failures
  • $Health check and readiness probe failures

>_ frequently asked questions

$ Do I need to install anything on my Kubernetes cluster?

No. LogMonitor integrates at the application level, not the cluster level. There are no DaemonSets, operators, or cluster-wide agents to install. Add the HTTP API call to your application code and you are done.

$ Can I monitor multiple services in a single dashboard?

Yes. Assign each microservice its own app ID or use metadata fields to differentiate them. The Live Console lets you filter logs by service, pod name, namespace, or any custom metadata.

$ How do I pass the API key securely in Kubernetes?

Store your LogMonitor API key in a Kubernetes Secret and mount it as an environment variable in your pod spec. This keeps the key out of your container images and source code.

$ Does LogMonitor work with Helm charts?

Yes. You can template the LogMonitor API key and app ID as Helm values and inject them as environment variables. No changes to your Helm chart structure are needed beyond adding the env vars.

$ Can I use LogMonitor alongside Prometheus and Grafana?

Yes. LogMonitor focuses on real-time log streaming and debugging, which complements metrics-based monitoring tools like Prometheus and Grafana. Use them together for full observability.
