Riemann on autoscaler

Autoscaler users Riemann http://riemann.io/

Riemann clients on components of your application

Components of your application should publish metrics to the Riemann running on the autoscaler component (by default on TCP:5666).

Riemann plugins and clients are available for almost all metrics collection applications. Check http://riemann.io/clients.html

Example of a custom Riemann publisher in Python https://github.com/slipstream/slipstream-auto-scale-apps/blob/master/client-nginx-webapp/client/app/locust-riemann-sender.py

Example of installation and configuration of write_riemann plugin for collectd https://github.com/slipstream/slipstream-auto-scale-apps/blob/master/client-nginx-webapp/webapp/deployment/collectd.sh

Riemann streams for scaling

https://nuv.la/module/konstan/scale/autoscaler component should be part of your application.

Set riemann_config_url input parameter to a public URL with the following files:

  • riemann-ss-streams.clj - Riemann streams using SlipStream scale up/down actions,
  • dashboard.json - Riemann dashboard layout and queries,
  • dashboard.rb - Riemann dashboard configuration.

See https://github.com/slipstream/slipstream-auto-scale-apps/tree/master/client-nginx-webapp/scaler/riemann for examples on how to write the above scripts and configuration files.

The main script to understand and write your own is riemann-ss-streams.clj.

Another exmple of Riemann configuration file with streams https://github.com/guardian/riemann-config/blob/master/main.clj

Riemann dashboard on autoscaler

After deployment of your application, the Riemann dashboard becomes available on http://<autoscaler IP>:6006.
