Modern Performance Monitoring

The modern Unix server floor can be a diverse universe of hardware from several
vendors and software from several sources. Often, the personnel needed to resolve
server floor performance issues are not available or, for security reasons,
not allowed to be present at the very moment of occurrence. Even when, as luck
might have it, the right personnel are actually present to witness a performance “event,” the
tools to measure and analyze the performance of the hardware and software have
traditionally been sparse and vendor-specific. Because few real Unix cross-platform
toolkits exist, there is no standard method for administrators to accurately
view an event, record it for later analysis, or share it with additional qualified
personnel for an efficient resolution.
