@ -89,11 +89,11 @@ By default, the perf collector will only collect metrics of the CPUs that
`node_exporter` is running on (ie
[`runtime.NumCPU`](https://golang.org/pkg/runtime/#NumCPU). If this is
insufficient (e.g. if you run `node_exporter` with its CPU affinity set to
specific CPUs) You can specify a list of alternate CPUs by using the
specific CPUs), you can specify a list of alternate CPUs by using the
`--collector.perf.cpus` flag. For example, to collect metrics on CPUs 2-6, you
would specify: `--collector.perf --collector.perf.cpus=2-6`. The CPU
configuration is zero indexed and can also take a stride value
`--collector.perf --collector.perf.cpus=1-10:5`, would collect on CPUs
configuration is zero indexed and can also take a stride value; e.g.
`--collector.perf --collector.perf.cpus=1-10:5` would collect on CPUs
1, 5, and 10.
