Alongside storage technologies and network components (switches, routers), servers form the basic foundation of an information system. Servers house the computing resources needed to run applications. Servers are connected to the information handled by applications in a variety of ways: local disks, direct SATA/SAS/SCSI connection to storage systems, connection via SAN or IP network to advanced storage systems, implementing high-availability functions on the scale of a computer room, a geographical site, or several remote geographical sites.
Whether you're a user of IT applications or SaaS/Paas/Iaas services, server availability and performance are essential to your satisfaction. That's why it's essential to monitor all server hardware and software characteristics.
Key points of server monitoring, hardware side :
Key points of server monitoring, software side :
For detailed supervision of server performance, you need to monitor the length of queues at processor and disk level. Disk supervision is also relevant, as it is decisive in ensuring data access performance: read/write operation throughput and latency must be implemented as part of server supervision.
Given the wealth of possibilities offered by server manufacturers, setting up server supervision can be a long and tedious task. The faster and more efficiently this can be done, the more the user of the supervision application will be able to rely on a complete catalog of service models, organized in the form of equipment models.
