New Relic Servers for Linux allows you to view and analyze critical system metrics, including CPU usage, physical memory, network activity, processes, and disk I/O utilization and capacity. This section provides information about compatibility and requirements, basic instructions on how to install and configure the Server Monitor agent, and links to more detailed information.
Compatibility and requirements
Before you install Servers for Linux, make sure your system meets these requirements.
|Servers for Linux||Requirements|
As a standard security measure for data collection, New Relic requires that your application server supports SHA-2 (256-bit). SHA-1 is not supported.
|Linux operating systems||
Servers supports the following operating systems:
New Relic also provides a binary tarball for manual installation on modern Linux-based operating systems with glibc 2.5+.
|Joyent SmartOS systems||
Servers supports Joyent's SmartOS zones on virtual machines running Joyent 2012Q2 and 2012Q4 SmartOS.
Servers for Linux supports Intel or Intel-compatible x86 or x86_64 architectures. Processors must support the SSE2 instruction set. This may exclude 2002 and earlier x86 and ia32 processors.
Servers for SmartOS supports x86_64 architectures.
Servers for Linux requires your firewall to allow an outgoing connection to New Relic's networks. The TCP port you identify in the configuration file depends on whether you use SSL.
For any installation, you will need your New Relic license key. This is a 40-character hexadecimal string that New Relic provides when you sign up for your account. To view your license key: From the New Relic menu bar, select (account) > Account settings.
Servers for Linux does not require root access to run. However, it does require root access to install, because the installer writes to protected directories and interacts with the system package databases.
Once you have set up your account, refer to the server monitor installation and configuration instructions as applicable:
- RedHat, CentOS (installing with yum or rpm)
- Ubuntu, Debian (installing with apt or dpkg)
- Other Linux (installing from a binary tarball)
- SmartOS (installing on Joyent SmartOS with pkgin)
- Configuring Servers (configuring New Relic Servers with nrsysmond.cfg)
