Deprecation warning

There was a long inconsistency when adding ports to the Prometheus target files, which
is now resolved.

Most users use the default port numbers for: ScyllaDB, node_exporter, and ScyllaDB manager agents and only use one target file. If that is your case, you do not need to change anything.

Scylla Monitoring will take the port numbers from the files if the files are set explicitly and contain ports.

For example, if you are specifying explicitly the node_exporter file (the -n flag to start-all.sh), you should ensure there are only IPs in the file with no ports or that you are using the correct node_exporter port number (by default, 9100).

So, if you just copy the scylla_servers file and use that with the ScyllaDB ports, it would no longer work.

$ cat node_exporter_servers.yml

  • labels:

cluster: my-cluster

dc: datacenter1


  • # Remove or change the ports part in your target

Important Note

Most likely, you can use a single target file for scylla_server and do not need to explicitly add a node_exporter or ScyllaDB manager agent file.

IPv6 Users

IPv6 users no longer need to add port numbers to the target files. It is recommended to use a single file (do not explicitly set the node_exporter file) without ports.
