editGolang expvar metricset
editThis is the expvar
metricset of the Golang module.
Go can expose its variables by the expvar API. With this metricset, you can collect all the expvar-exposed variables.
Fields
editFor a description of each field in the metricset, see the exported fields section.
Here is an example document generated by this metricset:
