### Monitoring using DNS queries
### Monitoring a service using ICMP
By prefixing `services[].url` with `icmp:\\`, you can monitor services at a very basic level using ICMP, or more
commonly known as "ping" or "echo":
```yaml
services:
- name: ICMP
url: "icmp://example.com"
conditions:
- "[CONNECTED] == true"
```
Only the placeholders `[CONNECTED]`, `[IP]` and `[RESPONSE_TIME]` are supported for services of type ICMP.
You can specify a domain prefixed by `icmp://` or an IP address.
### Monitoring a service using DNS queries
Defining a `dns` configuration in a service will automatically mark that service as a service of type DNS:
```yaml
services:
- name: example dns query
url: "8.8.8.8" # Address of the DNS server to use
interval: 30s

# A more minimal logging API for Go
Before you consider this package, please read [this blog post by the
inimitable Dave Cheney][warning-makes-no-sense]. I really appreciate what
he has to say, and it largely aligns with my own experiences. Too many
choices of levels means inconsistent logs.
This package offers a purely abstract interface, based on these ideas but with
a few twists. Code can depend on just this interface and have the actual
logging implementation be injected from callers. Ideally only `main()` knows
what logging implementation is being used.
# Differences from Dave's ideas
The main differences are:
1) Dave basically proposes doing away with the notion of a logging API in favor
of `fmt.Printf()`. I disagree, especially when you consider things like output
locations, timestamps, file and line decorations, and structured logging. I
restrict the API to just 2 types of logs: info and error.
Info logs are things you want to tell the user which are not errors. Error
logs are, well, errors. If your code receives an `error` from a subordinate
function call and is logging that `error` *and not returning it*, use error
logs.
2) Verbosity-levels on info logs. This gives developers a chance to indicate
arbitrary grades of importance for info logs, without assigning names with
semantic meaning such as "warning", "trace", and "debug". Superficially this
may feel very similar, but the primary difference is the lack of semantics.
Because verbosity is a numerical value, it's safe to assume that an app running
with higher verbosity means more (and less important) logs will be generated.
This is a BETA grade API.
There are implementations for the following logging libraries:
- **github.com/google/glog**: [glogr](https://github.com/go-logr/glogr)
- **k8s.io/klog**: [klogr](https://git.k8s.io/klog/klogr)
- **go.uber.org/zap**: [zapr](https://github.com/go-logr/zapr)
- **log** (the Go standard library logger):
[stdr](https://github.com/go-logr/stdr)
- **github.com/sirupsen/logrus**: [logrusr](https://github.com/bombsimon/logrusr)
- **github.com/wojas/genericr**: [genericr](https://github.com/wojas/genericr) (makes it easy to implement your own backend)
- **logfmt** (Heroku style [logging](https://www.brandur.org/logfmt)): [logfmtr](https://github.com/iand/logfmtr)
# FAQ
## Conceptual
## Why structured logging?
- **Structured logs are more easily queriable**: Since you've got
key-value pairs, it's much easier to query your structured logs for
particular values by filtering on the contents of a particular key --
think searching request logs for error codes, Kubernetes reconcilers for
the name and namespace of the reconciled object, etc
- **Structured logging makes it easier to have cross-referencable logs**:
Similarly to searchability, if you maintain conventions around your
keys, it becomes easy to gather all log lines related to a particular
concept.
- **Structured logs allow better dimensions of filtering**: if you have
structure to your logs, you've got more precise control over how much
information is logged -- you might choose in a particular configuration
to log certain keys but not others, only log lines where a certain key
matches a certain value, etc, instead of just having v-levels and names
to key off of.
- **Structured logs better represent structured data**: sometimes, the
data that you want to log is inherently structured (think tuple-link
objects). Structured logs allow you to preserve that structure when
outputting.
## Why V-levels?
**V-levels give operators an easy way to control the chattiness of log
operations**. V-levels provide a way for a given package to distinguish
the relative importance or verbosity of a given log message. Then, if
a particular logger or package is logging too many messages, the user
of the package can simply change the v-levels for that library.
## Why not more named levels, like Warning?
Read [Dave Cheney's post][warning-makes-no-sense]. Then read [Differences
from Dave's ideas](#differences-from-daves-ideas).
## Why not allow format strings, too?
**Format strings negate many of the benefits of structured logs**:
- They're not easily searchable without resorting to fuzzy searching,
regular expressions, etc
- They don't store structured data well, since contents are flattened into
a string
- They're not cross-referencable
- They don't compress easily, since the message is not constant
(unless you turn positional parameters into key-value pairs with numerical
keys, at which point you've gotten key-value logging with meaningless
keys)
## Practical
## Why key-value pairs, and not a map?
Key-value pairs are *much* easier to optimize, especially around
allocations. Zap (a structured logger that inspired logr's interface) has
[performance measurements](https://github.com/uber-go/zap#performance)
that show this quite nicely.
While the interface ends up being a little less obvious, you get
potentially better performance, plus avoid making users type
`map[string]string{}` every time they want to log.
## What if my V-levels differ between libraries?
That's fine. Control your V-levels on a per-logger basis, and use the
`WithName` function to pass different loggers to different libraries.
Generally, you should take care to ensure that you have relatively
consistent V-levels within a given logger, however, as this makes deciding
on what verbosity of logs to request easier.
## But I *really* want to use a format string!
That's not actually a question. Assuming your question is "how do
I convert my mental model of logging with format strings to logging with
constant messages":
1. figure out what the error actually is, as you'd write in a TL;DR style,
and use that as a message
2. For every place you'd write a format specifier, look to the word before
it, and add that as a key value pair
For instance, consider the following examples (all taken from spots in the
Kubernetes codebase):
- `klog.V(4).Infof("Client is returning errors: code %v, error %v",
responseCode, err)` becomes `logger.Error(err, "client returned an
error", "code", responseCode)`
- `klog.V(4).Infof("Got a Retry-After %ds response for attempt %d to %v",
seconds, retries, url)` becomes `logger.V(4).Info("got a retry-after
response when requesting url", "attempt", retries, "after
seconds", seconds, "url", url)`
If you *really* must use a format string, place it as a key value, and
call `fmt.Sprintf` yourself -- for instance, `log.Printf("unable to
reflect over type %T")` becomes `logger.Info("unable to reflect over
type", "type", fmt.Sprintf("%T"))`. In general though, the cases where
this is necessary should be few and far between.
## How do I choose my V-levels?
This is basically the only hard constraint: increase V-levels to denote
more verbose or more debug-y logs.
Otherwise, you can start out with `0` as "you always want to see this",
`1` as "common logging that you might *possibly* want to turn off", and
`10` as "I would like to performance-test your log collection stack".
Then gradually choose levels in between as you need them, working your way
down from 10 (for debug and trace style logs) and up from 1 (for chattier
info-type logs).
## How do I choose my keys
- make your keys human-readable
- constant keys are generally a good idea
- be consistent across your codebase
- keys should naturally match parts of the message string
While key names are mostly unrestricted (and spaces are acceptable),
it's generally a good idea to stick to printable ascii characters, or at
least match the general character set of your log lines.

// Package logr defines abstract interfaces for logging. Packages can depend on
// these interfaces and callers can implement logging in whatever way is
// appropriate.
//
// This design derives from Dave Cheney's blog:
// http://dave.cheney.net/2015/11/05/lets-talk-about-logging
//
// This is a BETA grade API. Until there is a significant 2nd implementation,
// I don't really know how it will change.
//
// The logging specifically makes it non-trivial to use format strings, to encourage
// attaching structured information instead of unstructured format strings.
//
// Usage
//
// Logging is done using a Logger. Loggers can have name prefixes and named
// values attached, so that all log messages logged with that Logger have some
// base context associated.
//
// The term "key" is used to refer to the name associated with a particular
// value, to disambiguate it from the general Logger name.
//
// For instance, suppose we're trying to reconcile the state of an object, and
// we want to log that we've made some decision.
//
// With the traditional log package, we might write:
// log.Printf("decided to set field foo to value %q for object %s/%s",
// targetValue, object.Namespace, object.Name)
//
// With logr's structured logging, we'd write:
// // elsewhere in the file, set up the logger to log with the prefix of
// // "reconcilers", and the named value target-type=Foo, for extra context.
// log := mainLogger.WithName("reconcilers").WithValues("target-type", "Foo")
//
// // later on...
// log.Info("setting foo on object", "value", targetValue, "object", object)
//
// Depending on our logging implementation, we could then make logging decisions
// based on field values (like only logging such events for objects in a certain
// namespace), or copy the structured information into a structured log store.
//
// For logging errors, Logger has a method called Error. Suppose we wanted to
// log an error while reconciling. With the traditional log package, we might
// write:
// log.Errorf("unable to reconcile object %s/%s: %v", object.Namespace, object.Name, err)
//
// With logr, we'd instead write:
// // assuming the above setup for log
// log.Error(err, "unable to reconcile object", "object", object)
//
// This functions similarly to:
// log.Info("unable to reconcile object", "error", err, "object", object)
//
// However, it ensures that a standard key for the error value ("error") is used
// across all error logging. Furthermore, certain implementations may choose to
// attach additional information (such as stack traces) on calls to Error, so
// it's preferred to use Error to log errors.
//
// Parts of a log line
//
// Each log message from a Logger has four types of context:
// logger name, log verbosity, log message, and the named values.
//
// The Logger name consists of a series of name "segments" added by successive
// calls to WithName. These name segments will be joined in some way by the
// underlying implementation. It is strongly recommended that name segments
// contain simple identifiers (letters, digits, and hyphen), and do not contain
// characters that could muddle the log output or confuse the joining operation
// (e.g. whitespace, commas, periods, slashes, brackets, quotes, etc).
//
// Log verbosity represents how little a log matters. Level zero, the default,
// matters most. Increasing levels matter less and less. Try to avoid lots of
// different verbosity levels, and instead provide useful keys, logger names,
// and log messages for users to filter on. It's illegal to pass a log level
// below zero.
//
// The log message consists of a constant message attached to the log line.
// This should generally be a simple description of what's occurring, and should
// never be a format string.
//
// Variable information can then be attached using named values (key/value
// pairs). Keys are arbitrary strings, while values may be any Go value.
//
// Key Naming Conventions
//
// Keys are not strictly required to conform to any specification or regex, but
// it is recommended that they:
// * be human-readable and meaningful (not auto-generated or simple ordinals)
// * be constant (not dependent on input data)
// * contain only printable characters
// * not contain whitespace or punctuation
//
// These guidelines help ensure that log data is processed properly regardless
// of the log implementation. For example, log implementations will try to
// output JSON data or will store data for later database (e.g. SQL) queries.
//
// While users are generally free to use key names of their choice, it's
// generally best to avoid using the following keys, as they're frequently used
// by implementations:
//
// - `"caller"`: the calling information (file/line) of a particular log line.
// - `"error"`: the underlying error value in the `Error` method.
// - `"level"`: the log level.
// - `"logger"`: the name of the associated logger.
// - `"msg"`: the log message.
// - `"stacktrace"`: the stack trace associated with a particular log line or
// error (often from the `Error` message).
// - `"ts"`: the timestamp for a log line.
//
// Implementations are encouraged to make use of these keys to represent the
// above concepts, when necessary (for example, in a pure-JSON output form, it
// would be necessary to represent at least message and timestamp as ordinary
// named values).
//
// Implementations may choose to give callers access to the underlying
// logging implementation. The recommended pattern for this is:
// // Underlier exposes access to the underlying logging implementation.
// // Since callers only have a logr.Logger, they have to know which
// // implementation is in use, so this interface is less of an abstraction
// // and more of way to test type conversion.
// type Underlier interface {
// GetUnderlying() <underlying-type>
// }

# go-ping
[![PkgGoDev](https://pkg.go.dev/badge/github.com/go-ping/ping)](https://pkg.go.dev/github.com/go-ping/ping)
[![Circle CI](https://circleci.com/gh/go-ping/ping.svg?style=svg)](https://circleci.com/gh/go-ping/ping)
A simple but powerful ICMP echo (ping) library for Go, inspired by
[go-fastping](https://github.com/tatsushid/go-fastping).
Here is a very simple example that sends and receives three packets:
```go
pinger, err := ping.NewPinger("www.google.com")
if err != nil {
panic(err)
}
pinger.Count = 3
err = pinger.Run() // Blocks until finished.
if err != nil {
panic(err)
}
stats := pinger.Statistics() // get send/receive/rtt stats
```
Here is an example that emulates the traditional UNIX ping command:
```go
pinger, err := ping.NewPinger("www.google.com")
if err != nil {
panic(err)
}
// Listen for Ctrl-C.
c := make(chan os.Signal, 1)
signal.Notify(c, os.Interrupt)
go func() {
for _ = range c {
pinger.Stop()
}
}()
pinger.OnRecv = func(pkt *ping.Packet) {
fmt.Printf("%d bytes from %s: icmp_seq=%d time=%v\n",
pkt.Nbytes, pkt.IPAddr, pkt.Seq, pkt.Rtt)
}
pinger.OnFinish = func(stats *ping.Statistics) {
fmt.Printf("\n--- %s ping statistics ---\n", stats.Addr)
fmt.Printf("%d packets transmitted, %d packets received, %v%% packet loss\n",
stats.PacketsSent, stats.PacketsRecv, stats.PacketLoss)
fmt.Printf("round-trip min/avg/max/stddev = %v/%v/%v/%v\n",
stats.MinRtt, stats.AvgRtt, stats.MaxRtt, stats.StdDevRtt)
}
fmt.Printf("PING %s (%s):\n", pinger.Addr(), pinger.IPAddr())
err = pinger.Run()
if err != nil {
panic(err)
}
```
It sends ICMP Echo Request packet(s) and waits for an Echo Reply in
response. If it receives a response, it calls the `OnRecv` callback.
When it's finished, it calls the `OnFinish` callback.
For a full ping example, see
[cmd/ping/ping.go](https://github.com/go-ping/ping/blob/master/cmd/ping/ping.go).
## Installation
```
go get -u github.com/go-ping/ping
```
To install the native Go ping executable:
```bash
go get -u github.com/go-ping/ping/...
$GOPATH/bin/ping
```
## Supported Operating Systems
### Linux
This library attempts to send an "unprivileged" ping via UDP. On Linux,
this must be enabled with the following sysctl command:
```
sudo sysctl -w net.ipv4.ping_group_range="0 2147483647"
```
If you do not wish to do this, you can call `pinger.SetPrivileged(true)`
in your code and then use setcap on your binary to allow it to bind to
raw sockets (or just run it as root):
```
setcap cap_net_raw=+ep /path/to/your/compiled/binary
```
See [this blog](https://sturmflut.github.io/linux/ubuntu/2015/01/17/unprivileged-icmp-sockets-on-linux/)
and the Go [x/net/icmp](https://godoc.org/golang.org/x/net/icmp) package
for more details.
### Windows
You must use `pinger.SetPrivileged(true)`, otherwise you will receive
the following error:
```
socket: The requested protocol has not been configured into the system, or no implementation for it exists.
```
Despite the method name, this should work without the need to elevate
privileges and has been tested on Windows 10. Please note that accessing
packet TTL values is not supported due to limitations in the Go
x/net/ipv4 and x/net/ipv6 packages.
### Plan 9 from Bell Labs
There is no support for Plan 9. This is because the entire `x/net/ipv4`
and `x/net/ipv6` packages are not implemented by the Go programming
language.

// Package ping is a simple but powerful ICMP echo (ping) library.
//
// Here is a very simple example that sends and receives three packets:
//
// pinger, err := ping.NewPinger("www.google.com")
// if err != nil {
// panic(err)
// }
// pinger.Count = 3
// err = pinger.Run() // blocks until finished
// if err != nil {
// panic(err)
// }
// stats := pinger.Statistics() // get send/receive/rtt stats
//
// Here is an example that emulates the traditional UNIX ping command:
//
// pinger, err := ping.NewPinger("www.google.com")
// if err != nil {
// panic(err)
// }
// // Listen for Ctrl-C.
// c := make(chan os.Signal, 1)
// signal.Notify(c, os.Interrupt)
// go func() {
// for _ = range c {
// pinger.Stop()
// }
// }()
// pinger.OnRecv = func(pkt *ping.Packet) {
// fmt.Printf("%d bytes from %s: icmp_seq=%d time=%v\n",
// pkt.Nbytes, pkt.IPAddr, pkt.Seq, pkt.Rtt)
// }
// pinger.OnFinish = func(stats *ping.Statistics) {
// fmt.Printf("\n--- %s ping statistics ---\n", stats.Addr)
// fmt.Printf("%d packets transmitted, %d packets received, %v%% packet loss\n",
// stats.PacketsSent, stats.PacketsRecv, stats.PacketLoss)
// fmt.Printf("round-trip min/avg/max/stddev = %v/%v/%v/%v\n",
// stats.MinRtt, stats.AvgRtt, stats.MaxRtt, stats.StdDevRtt)

You can use this library for easier [go-fuzz](https://github.com/dvyukov/go-fuzz)ing.
go-fuzz provides the user a byte-slice, which should be converted to different inputs
for the tested function. This library can help convert the byte slice. Consider for
example a fuzz test for a the function `mypackage.MyFunc` that takes an int arguments:
```go
// +build gofuzz
package mypackage
import fuzz "github.com/google/gofuzz"
func Fuzz(data []byte) int {
var i int
fuzz.NewFromGoFuzz(data).Fuzz(&i)
MyFunc(i)
return 0
}

There are helper functions available to get the value stored in a Flag if you have a FlagSet but find
it difficult to keep up with all of the pointers in your code.
If you have a pflag.FlagSet with a flag called 'flagname' of type int you
can use GetInt() to get the int value. But notice that 'flagname' must exist
and it must be an int. GetString("flagname") will fail.
