- m3dbInstallerScript -
- m3db shall be deployed only on a 3 node cluster, and the nodes shall be labelled. For labelling of the nodes, refer the manual steps in the same doc. Labelling of nodes is a pre-requisite.
- This script shall install m3db nodes.
- Helm charts and profile : m3dbHelmCharts
- This script shall also bring m3coordinator-m3db-cluster service.
- A sidecar process, M3Coordinator, allows M3DB to act as the long-term storage for Prometheus. Its responsible for integration with prometheus

- CollectD-PrometheusScript -
- This script shall install collectd and prometheus.
- CollectD-PrometheusScript - This script shall install collectd and prometheus. Helm charts for collectd and prometheus : collectd and prometheus
- For connecting prometheus and m3coordinator, in the remote write section of the values.yaml of the prometheus helm charts, add the following:
| Code Block | ||||
|---|---|---|---|---|

remoteWrite:
# - url: http://remote1/push
- url: "http://192.168.121.12:31772/api/v1/prom/remote/write"
writeRelabelConfigs:
- targetLabel: metrics_storage
replacement: m3db_remote |
NOTE , in the above 192.168.121.12 is the ip of the cluster node where m3db is running. 31772 is the NodePort of the m3coordinator.
After running the following pods and services shall be present in the nodes edge1 and edge2
