Ping監視とHttp監視 - どちらを選ぶべきか？

ネットワークの問題を理解し診断することは、インターネットを利用して顧客とやり取りする組織にとって非常に重要です。PingとHTTPモニタリングは、ネットワークを円滑に稼動させ、問題を解決したいネットワーク・マネージャーやウェブマスターにとって重要なリソースです。それぞれのツールには明確な目的があり、ネットワークとアプリケーションの様々なレイヤーのオペレーションを把握することができます。

Pingモニタリングとは？

  • 何をするのか？ Pingモニタリング は、ICMP（インターネット制御メッセージ・プロトコル）を使って、ネットワーク上のネットワーク・デバイス（サーバー、ルーター、スイッチなど）の可用性をチェックする。特定のIPアドレスにデータのパケットを送信し、応答を待ち、往復にかかった時間を計測する。
  • 目的 その主な目的は、ホストの到達可能性と、発信元ホストから宛先コンピュータに送信されるメッセージのラウンドトリップタイム（RTT）をチェックすることである。
  • 使用例： ホストがネットワーク上で稼働しているかどうかを確認する基本的なネットワークのトラブルシューティングに広く使用されている。ネットワーク接続の問題やファイアウォールの存在、ネットワークの輻輳を特定するのに役立ちます。
  • 制限： Pingモニタリングでは、上位プロトコル（HTTPなど）のパフォーマンスやアプリケーション固有の問題についての情報は得られません。単にホストに到達可能かどうかがわかるだけで、ウェブサービスやアプリケーションが正しく機能しているかどうかはわかりません。

Agent-less vs Agent-based Monitoring

In today’s digital world, IT infrastructure reliability and performance are becoming critical to business success. Monitoring, in effect, acts as the backbone of such efforts in enabling organizations to detect issues at an early stage, optimizing resource utilization, and minimizing downtime. However, finding the right way to monitor may be a challenge as modern IT environments are growing more complex. There are two major approaches mainly: agent-based monitoring and agent-less monitoring; each with various advantages and challenges. Understand the difference; understand the strength, the limitation, and thus make an educated choice. This blog compares side-by-side two different approaches, presenting Xitoring, which offers combined strengths from both for the comprehensive, efficient, and scalable monitoring of infrastructure.

What is Agent-less Monitoring?

Agent-less monitoring refers to the process of monitoring and data collection from servers, network devices, and other IT components without the need for software agents on the monitored systems. It would, therefore, rely on other external mechanisms to gather information. This approach thus becomes highly useful in an environment where deploying agents is either not practical or highly undesirable. There are generally two ways in which agent-less monitoring is done:

Server monitoring vs Uptime monitoring

What is Server Uptime?

The current uptime of a server is the time elapsed since its last reboot. Years, months, days, hours, minutes, and seconds express uptime. Uptime starts at 0 (zero) every time the server starts up again, and it keeps going up as long as the server is working.

Why is Uptime Monitoring Important?

Monitoring is standard in the IT industry because it allows you to maintain the ideal state of the company’s servers. The server performance monitoring procedure is pretty straightforward; it routinely collects server data and analyzes it in real-time or retrospectively. This enables us to guarantee that the servers run properly, delivering their intended purpose.
You may monitor nearly everything, including processor performance control, memory consumption, network, and disk space bandwidth, and server-related issues. However, understanding how to monitor a server is insufficient. It is essential to comprehend why it is such an integral component of its security. The purpose of monitoring is to provide information on failures and performance issues and to anticipate and prevent problems. In practice, this implies that faults or anomalies are discovered so quickly that the entire organization’s service, application, or operation is not halted. As a result, the company’s server infrastructure functions properly and reliably, and the company does not incur losses due to lengthy system outages.
