| bufio | Package bufio implements buffered I/O. It wraps an io.Reader or io.Writer object, creating another object (Reader or Writer) that also implements the interface but provides buffering and some help for textual I/O. |
| bytes | Package bytes implements functions for the manipulation of byte slices. |
| compress/gzip | Package gzip implements reading and writing of gzip format compressed files, as specified in RFC 1952. |
| encoding/json | Package json implements encoding and decoding of JSON as defined in RFC 7159. |
| errors | Package errors implements functions to manipulate errors. |
| expvar | Package expvar provides a standardized interface to public variables, such as operation counters in servers. |
| fmt | Package fmt implements formatted I/O with functions analogous to C's printf and scanf. |
| github.com/beorn7/perks/quantile | Package quantile computes approximate quantiles over an unbounded data stream within low memory and CPU bounds. |
| github.com/golang/protobuf/proto | Package proto provides functionality for handling protocol buffer messages. |
| github.com/prometheus/client_golang/prometheus/internal | |
| github.com/prometheus/client_model/go | |
| github.com/prometheus/common/expfmt | Package expfmt contains tools for reading and writing Prometheus metrics. |
| github.com/prometheus/common/model | Package model contains common data structures that are shared across Prometheus components and libraries. |
| github.com/prometheus/procfs | Package procfs provides functions to retrieve system, kernel and process metrics from the pseudo-filesystem proc. |
| io | Package io provides basic interfaces to I/O primitives. |
| io/ioutil | Package ioutil implements some I/O utility functions. |
| math | Package math provides basic constants and mathematical functions. |
| net | Package net provides a portable interface for network I/O, including TCP/IP, UDP, domain name resolution, and Unix domain sockets. |
| net/http | Package http provides HTTP client and server implementations. |
| os | Package os provides a platform-independent interface to operating system functionality. |
| path/filepath | Package filepath implements utility routines for manipulating filename paths in a way compatible with the target operating system-defined file paths. |
| runtime | Package runtime contains operations that interact with Go's runtime system, such as functions to control goroutines. |
| runtime/debug | Package debug contains facilities for programs to debug themselves while they are running. |
| sort | Package sort provides primitives for sorting slices and user-defined collections. |
| strconv | Package strconv implements conversions to and from string representations of basic data types. |
| strings | Package strings implements simple functions to manipulate UTF-8 encoded strings. |
| sync | Package sync provides basic synchronization primitives such as mutual exclusion locks. |
| sync/atomic | Package atomic provides low-level atomic memory primitives useful for implementing synchronization algorithms. |
| time | Package time provides functionality for measuring and displaying time. |
| unicode/utf8 | Package utf8 implements functions and constants to support text encoded in UTF-8. |
