SingleStore Exporter

singlestore_exporter collects metrics from SingleStore (formerly MemSQL) clusters.

singlestore_exporter aims to collect node and cluster states that are not gathered by memsql_exporter, focusing on enhancing monitoring capabilities by providing insights into metrics and statuses not covered by the latter.

Building and running

Build

make build

Run

DATA_SOURCE_NAME='{ID}:{PASSWORD]@tcp({FQDN}:{$PORT})/' ./singlestore_exporter <flags>
# When Exporter Start, You can check metrics
# http://localhost:9105/metrics

# Or you can run exporter from source code
DATA_SOURCE_NAME='{ID}:{PASSWORD]@tcp({FQDN}:{$PORT})/' go run main.go <flags>

Deploy

singlestore_exporter should be run on nodes where SingleStore is installed to collect node status metrics, because it uses memsqlctl to check node's status.

For systemd integration, refer to the example service files under the deploy/ folder.
