Node-Level Metrics
Node-level metrics are recorded specific to each node within your LogScale cluster and will have a field, @host, that contains the hostname number within the cluster. To query across the nodes, a query will need to aggregate across all the records using a reference point, for example the time of the metric entry:
logscale
name="ingest-bytes"
| day := time:dayOfMonth(@timestamp)
| groupBy(day,function=sum(m1))The full list of node-level metrics is shown in Node-Level Metrics table.
