Functions ¶
func CleanupTestStreams ¶
func CleanupTestStreams(ts []*TestStream)
CleanupTestStreams closes all sockets and streams as well removes temporary file ressources for an array of TestStreams.
Types ¶
type BadLogstashOutputError ¶
type BadLogstashOutputError struct {
// contains filtered or unexported fields
}
BadLogstashOutputError indicates that Logstash emitted a line that couldn't be interpreted as an event, typically because it wasn't valid JSON.
func (BadLogstashOutputError) Error ¶
func (e BadLogstashOutputError) Error() string
Error returns a string representation of the error.
type Event ¶
type Event map[string]interface{}
Event represents a Logstash event, i.e. basically a JSON document.
type FieldSet ¶
type FieldSet map[string]interface{}
FieldSet contains a set of fields for a Logstash event and can be marshaled as a Logstash-compatible string that's acceptable to an add_field option for an input or filter.
func (FieldSet) IsValid ¶
IsValid inspects the field set and returns an error if there are any values that Logstash obviously would disapprove of (like objects in arrays).
func (FieldSet) LogstashHash ¶
LogstashHash converts a FieldSet into a Logstash-style hash that e.g. is accepted by an add_field directive in a configuration file, i.e. it has the form { "key1" => "value1" ... "keyN" => "valueN" }.
type Invocation ¶
type Invocation struct {
LogstashPath string
// contains filtered or unexported fields
}
Invocation represents an invocation of Logstash, including the details of the input arguments and how to capture its log output.
func NewInvocation ¶
func NewInvocation(logstashPath string, logstashArgs []string, logstashVersion *semver.Version, configs ...string) (*Invocation, error)
NewInvocation creates a new Invocation struct that contains all information required to start Logstash with a caller-selected set of configurations.
func (*Invocation) Args ¶
func (inv *Invocation) Args(inputs string, outputs string) ([]string, error)
Args returns a complete slice of Logstash command arguments for the given input and output plugin configuration strings.
func (*Invocation) Release ¶
func (inv *Invocation) Release()
Release releases any resources allocated by the struct.
type ParallelProcess ¶
type ParallelProcess struct {
// contains filtered or unexported fields
}
ParallelProcess represents the invocation and execution of a Logstash child process that emits JSON events from multiple inputs through filter to multiple outputs configuration files supplied by the caller.
func NewParallelProcess ¶
func NewParallelProcess(inv *Invocation, testStream []*TestStream, keptEnvVars []string) (*ParallelProcess, error)
NewParallelProcess prepares for the execution of a new Logstash process but doesn't actually start it. logstashPath is the path to the Logstash executable (typically /opt/logstash/bin/logstash). The configs parameter is one or more configuration files containing Logstash filters.
func (*ParallelProcess) Release ¶
func (p *ParallelProcess) Release()
Release frees all allocated resources connected to this process.
func (*ParallelProcess) Start ¶
func (p *ParallelProcess) Start() error
Start starts a Logstash child process with the previously supplied configuration.
func (*ParallelProcess) Wait ¶
func (p *ParallelProcess) Wait() (*ParallelResult, error)
Wait blocks until the started Logstash process terminates and returns the result of the execution.
type ParallelResult ¶
type ParallelResult struct {
// Success indicates whether the execution was successful,
// i.e. whether the Logstash process terminated with a zero
// exit status.
Success bool
// Events contains a slice of the events emitted from
// Logstash.
Events [][]Event
// Log contains the contents of the Logstash log file.
Log string
// Output contains stdout and stderr output (if any) of
// the Logstash process. If the process fails during
// initialization clues can probably be found here.
Output string
}
ParallelResult contains the results of a parallel Logstash execution, where multiple test cases are run in parallel via unix domain sockets.
type Process ¶
type Process struct {
// Input will be connected to the stdin stream of the started
// Logstash process. Make sure to close it when all data has
// been written so that the process will terminate.
Input io.WriteCloser
// contains filtered or unexported fields
}
Process represents the invocation and execution of a Logstash child process that emits JSON events from the input and filter configuration files supplied by the caller.
func NewProcess ¶
func NewProcess(inv *Invocation, inputCodec string, fields FieldSet, keptEnvVars []string) (*Process, error)
NewProcess prepares for the execution of a new Logstash process but doesn't actually start it. logstashPath is the path to the Logstash executable (typically /opt/logstash/bin/logstash), inputCodec is the desired codec for the stdin input and inputType the value of the "type" field for ingested events. The configs parameter is one or more configuration files containing Logstash filters.
func (*Process) Release ¶
func (p *Process) Release()
Release frees all allocated resources connected to this process.
type Result ¶
type Result struct {
// Success indicates whether the execution was successful,
// i.e. whether the Logstash process terminated with a zero
// exit status.
Success bool
// Events contains a slice of the events emitted from
// Logstash.
Events []Event
// Log contains the contents of the Logstash log file.
Log string
// Output contains stdout and stderr output (if any) of
// the Logstash process. If the process fails during
// initialization clues can probably be found here.
Output string
}
Result contains the result of a Logstash execution.
type TestStream ¶
type TestStream struct {
// contains filtered or unexported fields
}
TestStream contains the input and output streams for one test case.
func NewTestStream ¶
NewTestStream creates a TestStream, inputCodec is the desired codec for the stdin input and inputType the value of the "type" field for ingested events. The timeout defines, how long to wait in Write for the receiver to become available.
func (*TestStream) Cleanup ¶
func (ts *TestStream) Cleanup()
Cleanup closes and removes all temporary resources for a TestStream.
func (*TestStream) Close ¶
func (ts *TestStream) Close() error
Close closes the sender of the TestStream.
