After you install the New Relic server monitor, refer to this document for configuration settings.
The configuration file for Linux-based System Monitor daemons is at
/etc/newrelic/nrsysmond.cfg. If you change any settings, you must restart the daemon before the changes will take effect.
Here is a summary of Linux-based System Monitor configuration settings.
The 40-character license key provided to you by New Relic. To view your license key: From the New Relic title bar, select (account) > Account settings. For more information, see License key.
A valid license key is required in order for the server monitor to start.
The level of detail you want to see in the log files:
You can also set the
loglevel from the command line.
The name of the file where the server monitor will store its log messages. The amount of detail included is controlled by the
Asks the server monitor to connect to the New Relic collector via a HTTP proxy. Possible formats include:
If you do not specify a port, it uses the default 1080.
Indicates whether or not to use SSL for communication with the New Relic collector (default: false). Certain rare cases may require you to modify the SSL certificate settings below.
The name of a PEM-encoded Certificate Authority (CA) bundle to use for SSL connections. This should very rarely need to be set.
By default, the monitor will attempt to find the bundle in the most common locations. If you need to use SSL and the monitor is unable to locate a CA bundle, then either use this, or use
ssl_ca_path to inform the server monitor where to find CAs.
Use a comma-separated list of path names to bundle files. Default:
If your SSL installation does not use CA bundles but has a directory containing PEM-encoded CA files, set this option to the name of the directory containing all the CA files. Default:
The file used to record where the server monitoring daemon will store its process ID (PID). This is used by
the init script to determine whether the monitor is currently running and which PID to kill when shutting down. Default:
The host name of the New Relic collector. Default:
collector.newrelic.com. Caution: Do not change this setting unless New Relic Support advises you to do so. The format is host[:port]. A port number of 0 will imply port 80 without SSL enabled, and port 443 with SSL enabled.
The amount of time the monitor should wait to contact the collector host, in seconds (default: 30). If the connection cannot be established in this period of time, the monitor will progressively back off in 15 second increments to a maximum of 300 seconds (5 minutes). Once the initial connection has been established, the timeout value is reset back to the value specified here.
The server monitoring agent requires your firewall to allow an outgoing connection to New Relic's networks on TCP port 80 (or port 443 if you configure the agent to use SSL). To test the outgoing connection and incoming response, use curl or wget.
curl -v http://collector.newrelic.com/status/mongrel [or] curl -v https://collector.newrelic.com/status/mongrel // if SSL
wget -O- http://collector.newrelic.com/status/mongrel [or] wget -O- https://collector.newrelic.com/status/mongrel // if SSL
