newrelic service doesn’t start on CentOS: Solution Run as Root
Today one of my virtual servers suddenly showed up as offline in my New Relic console (Which is an amazing tool and free by the way).
I checked the log file /var/log/newrelic/nrsysmond.log and it had these contents:
2015-08-15 02:06:04.512 (915) error: nria_context_create(): SIGAR_OK != status; goto error; status=13
2015-08-15 02:06:04.512 (915) error: nria_context_create(): in error label
2015-08-15 02:06:04.512 (915) error: failed to create sampling context
2015-08-15 02:06:04.512 (913) info: worker process exited with 1 - NOT restarting
I found a post on the New Relic forum which provided the solution:
-> Run the newrelic service as root
This can be done by editing /etc/sysconfig/newrelic-sysmond and uncommenting the option RUNAS:
# User to run the Server Monitor as
Not a perfect solution since ideally this should run with the newrelic user but at least it got the server online on my console again.
