New Relic Servers Overview page

For the latest, most advanced host monitoring, check out New Relic Infrastructure.

To view summary and detail information about a specific server: From the Servers list, select a server. You can also view the Overview page from any of the selected server's pages by selecting Overview.

Server Overview page details

This image shows the server overview page. The Server Overview page provides summary information
Servers > (selected server) > Overview: The Server Overview page provides summary information.

The Server Overview page shows summary information about a specific server for the selected time period. Use any of New Relic's standard user interface functions and page functions to drill down into detailed information.

Server Overview Notes
Charts Charts show CPU usage information, load averages, physical memory, disk utilization, and network I/O.
Operating system and architecture Information about the operating system and architecture includes the number of CPUs and the amount of RAM installed on this host. If you have renamed the server, the original server name also appears with the new name.
Applications The list of applications monitored by this server includes the response time, throughput, and errors. For additional details, select the app's name. (The app's Overview page appears.)
Processes The sortable table of running processes includes the name, user, count, and CPU and memory usage. For additional details, select the Processes table's title. (The server's Processes page appears.)

From the Server Overview page you can:

  • View additional page details by selecting the Processes, Network, or Disks tab.
  • Select a different server from the dropdown.
  • Return to the complete servers list by selecting Servers from the New Relic menu bar or by selecting from the dropdown next to the current server's name.

CPU states

The CPU chart shows different states. These may include:

CPU States Explanation
IO Wait Time that the CPU is idle and there is at least one input or output operation in progress.

CPU time "stolen" from this virtual machine by the hypervisor for other tasks (such as running another virtual machine).

New Relic will only show increased stolen activity when the app has activity. New Relic does not count stolen time for CPU activity alerts.

For example, if resources are stolen but a virtual machine is not actively processing, you see no stolen load. However, if resources are being stolen and a virtual machine is even slightly active, the load spikes proportionally. The more stolen resources there are, the less active the virtual machine needs to be to generate a high load rating.

System Time used by the kernel and its associated processes. This is mostly system housekeeping, but things like RAID rebuilding, and handling network transmission and checksums fall into this category as well.
User Time the CPU has spent running users' processes.
Idle Anything between the top of your graphed usage and 100% (in white) is time when the CPU is not doing anything at all.

Chart descriptions

Besides CPU, the remaining charts represent the following information:

Chart Explanation
Physical memory The physical memory chart illustrates the percentage of physical memory and swap space being used.
Disk I/O Utilization This chart represents the percentage of input versus output for the disks on a server. This is not a representation of throughput.
Network I/O The Network I/O chart illustrates the input and output being transmitted and recieved, in units of Megabytes per second.
Load average

The load average is derived from Linux system data provided in /proc/loadavg.


user@host:~$ cat /proc/loadavg
0.00 0.01 0.05 1/84 3390

The first three numbers listed in /proc/loadavg are the values that the uptime command provides. These values represent the average system load in the last 1, 5, and 15 minutes. The chart in the New Relic Server monitor page is the 1 minute value at the time the data is sampled.
