heka_dashboard_exporter

heka_dashboard_exporter is a very simple application that connects to the heka dashboard and exports the data for Prometheus consumption. Currently, the exporter is hard-coded to consume these heka sub-systems:

• decoders
• encoders
• filters
• globals
• outputs

You must enable the DashboardOutput in heka. Also, I recommend setting the interval to be something less than your Prometheus scraping interval.

[DashboardOutput]
ticker_interval = 15

Then, start the exporter like this:

./heka_dashboard_exporter -heka.url="http://127.0.0.1:4352/data/heka_report.json"

Prometheus-compatible metrics will be available at http://127.0.0.1:9111/metrics

To listen on an alternate port, use the web.listen-address flag:

./heka_dashboard_exporter -heka.url="http://127.0.0.1:4352/data/heka_report.json" -web.listen-address=":9999"

Docker container

If you prefer, you can run the pre-built docker container with the same options as above:

docker run -d -p 9111:9111 dckr/heka_dashboard_exporter -heka.url="http://somehekainstance:4352/data/heka_report.json"
