+status based on I<uptime> metric.

+
+ rsyslog should be configured such that it sends data to the IP and port you

+
+ if $programname != 'collectd' then
+ *.* @192.168.0.2:6666
+
+ This plugin is designed to consume JSON rsyslog data, so a more complete
+ rsyslog configuration would look like so (where we define a JSON template
+ and use it when sending data to our IP and port):
+
+ $template ls_json,"{%timestamp:::date-rfc3339,jsonf:@timestamp%, \
+ %source:::jsonf:@source_host%,\"@source\":\"syslog://%fromhost-ip:::json%\", \

+
+ if $programname != 'collectd' then
+ *.* @192.168.0.2:6666;ls_json
+
+ Please note that these rsyslog.conf examples are *not* complete, as rsyslog
