What is server management?

Server management is defined as the act of managing server infrastructure and overseeing its performance by continuous monitoring using various tools or methodologies. Server management helps in increasing agility of business-critical applications and aims at optimizing the performance of both physical and virtual servers.

Server management with OpManager:

With many of today's applications and services moving to a data center, virtualization and server consolidation are creating new management challenges. OpManager provides IT administrators, a single management console for in-depth visibility and control of both physical and virtual servers across Windows, Linux, Unix, VMware, Hyper-V and Xen server platforms.

OpManager assists in server management by:

OpManager is a perfect tool to showcase server performance management, fault management and applications monitoring. We found it very user friendly and comprehensive in nature. It gives a complete picture of the Network, Systems, applications and services.

Monitoring in server management:

Monitoring servers proactively for availability and response time is vital for server management. OpManager the trusted network and server management software, actively monitors over 300 critical server performance metrics like CPU utilization, disk utilization, partition-wise memory utilization etc. along with monitoring services and processes. OpManager's fault monitoring includes threshold based alerts and notifications for server's availability and health.

OpManager monitors the performance of

  • VMware ESX servers and Guest OS
  • Application servers, Active Directory, SQL and Exchange servers
  • Hyper-V servers
  • Xen servers

Monitoring in server management

Troubleshooting in server management:

A robust server management tool detects and troubleshoots server issues, that would otherwise impact businesses/end users. OpManager detects server performance problems like CPU busy time, low available memory etc. beforehand and sends intelligent and actionable alerts to remedy them. With workflows, it is possible to automate the troubleshooting process in OpManager. Advanced alerting that can even log a trouble ticket into an integrated helpdesk system ensures that you identify potential problems much before users could get affected.

Did you know?
You can remotely troubleshoot server faults using OpManager’s server diagnostic tools. Once you are alerted on a problem, within a single click from the monitoring dashboard, you can immediately view real–time performance trends of the problem server, investigate and even stop services or processes that cause the performance degradation.

Server troubleshooting tools in OpManager:

Here are a few tools in OpManager that help in troubleshooting first and second level server faults.

Ping and Traceroute: The ping tool in server snapshot pages can be used to ping the server directly to monitor its availability and uptime. Traceroute allows you to identify the network path and helps differentiate issues with the server or the network.

Remote Server Connection: Accessing servers remotely is useful for setting up a VPN, run a version control system, backing up data and other IT tasks. OpManager allows you to access servers remotely within its web client. You can either connect to the server directly using SNMP, WMI, Telnet/SSH credentials with the Remote Desktop connection or connect to a particular web service running on the server through HTTP or HTTPS connection.(IE only)

Downtime Scheduler: OpManager's downtime scheduler helps schedule maintenance activities on your servers periodically. This feature can also be extended to other network devices like switches, routers etc. During the scheduled maintenance period, OpManager intelligently ceases monitoring for that particular device.

Server troubleshooting

Test monitor: OpManager allows you to configure server performance monitors for critical performance metrics like CPU utilization, memory utilization, partition details etc. The test monitor verifies if the metric is being monitored by OpManager and provides the value of the monitored metric. It also lists the possible reasons when data is not received from the server.

Automating server management with workflows:

Server management includes fixing server faults and routine maintenance tasks that are repetitive and laborious in nature. Automating such management tasks can help IT admins maximize their productivity by saving time and effort. OpManager supports close to 80 actions that can be automated with its workflows.

Some of the server management tasks can be automated with OpManager workflows are:

  • Place/exit a server from maintenance.
  • Stop/Restart/Suspend a virtual machine.
  • Refresh Datastore in virtual servers.
  • Stop/Shut Down/Restart Guest OS.
  • List server process by disk read/write/memory/CPU usage.
  • Start/Stop/Pause/Restart windows services.
  • Execute scripts.

Server troubleshooting

SLA management:

With OpManager, it is possible to group devices according to the service they facilitate and ensure that for each business service, SLAs are being met. OpManager alerts for falling SLAs and from the intuitive business service maps you can drill down and troubleshoot problem devices to quickly restore SLAs.

Capacity Planning in server management:

Through over 100 out–of–the–box server performance reports on availability, resource utilization, fault events etc., OpManager provides ready–to–use information for your next capacity addition. What’s more, you can create your own customized reports, e.g. an end of the day report on the availability & response times of all the servers in the Datacenter, and have these automatically sent to your mailbox every day.
