Using Performance Counters to Monitor the Performance of Critical Servers

Introduction

The Department of Public Welfare (DPW) monitors performance of critical servers using performance counters.

Critical servers include enterprise-level servers that host business-critical applications. Business-critical applications can include applications used by agency personnel, business partners, or other users external to DPW, such as public Internet users. Critical servers also include infrastructure servers, such as domain controllers and host name servers. DPW houses the majority of these servers in the server room at the Willow Oak Building. The Office of Information Systems (OIS) supports them directly.

Base performance counters target key server components including, CPU, memory, disk, and network counters. Base counters can be used to determine whether a server is operating efficiently. They can also be used to help proactively identify problems before the problems bring down a machine. Support staff are alerted when critical thresholds are reached, or/and when additional, more specialized counters may be needed.

Purpose

The purpose of this document is to identify and describe base and advanced performance counters to use in monitoring the performance of critical servers at DPW.
