Evening all, I've mostly finished my last personal project, so my thoughts are turning to omriemann.
I'm trying to work out how we might configure the module. Riemann requires that we send a protobuf encoded message containing a few pre-set fields, plus whatever additional fields we feel like forwarding. host: localhost service: cpu-load-average/1m state: ok time: 1480661786 description: "everything is perfectly fine" tags: ["laptop", "personal"] metric: 0.58 ttl: 120 my-custom-field: 27 This makes it unusual for an rsyslog module: usually rsyslog is happy to ship arbitrary strings to a destination and only cares about the _framing_ of your data: omelasticsearch, ommysql, omkafka, omrelp etc. all accept some number of static parameters, plus a free-form template for the actual message. Omriemann, in order to be useful, will need to impose some structure on the message itself. How do people think we should configure the module so that people have flexibility over the host, metric value, metric name, and tags on a per-message basis? I guess the simplest thing that could possibly work is defining a simple message format, eg. `host=foo; metric_f=0.6; service=rsyslog.impstats/utime; timestamp=1480661786` that messages need to conform to. We can then parse out the key/value pairs in the module and encode them to protobuf. Alternatively, we could set up the structure of the message in the config itself, like this: action( type="omriemann" host="$hostname" metric="$!metric.value" service="$!metric.name") That seems more user-friendly, but rules out using custom fields. I guess I'd have to create a new template per-field during module begin. On a related note, I think I remember seeing some discussion of conversion functions recently. Some of the fields need to valid integers, floats, unix timestamps etc. What's the best way of parsing those out? _______________________________________________ rsyslog mailing list http://lists.adiscon.net/mailman/listinfo/rsyslog http://www.rsyslog.com/professional-services/ What's up with rsyslog?
