## Info
Package for sending logs to the storage, for the subsequent withdrawal of the traceViewer service and display there.
Supported storage drivers:
- [x] Console // invalid realisation
- [x] Postgres // invalid realisation
- [ ] Algolia
- [ ] ElasticSearch
## Content
- Thread Line: Line of logs. Contains Logs. Thread ID = First root Log ID
- Log: data node. May contents other Logs as children
## ScreenShort of TraceViewer based on traceFall
## Union Logs
Independent Logs may union to one log thread via `LogParentShadow`
```go
logChild := tracefall.NewLog(`prepare Scrapping`).SetApplication(`micro.1`)
logChild.ParentFromShadow(job.LogShadow)
```
#### Example
`microservice #1`
```go
logParent := tracefall.NewLog(`Start`)
// send to RabbitMQ job with logParent.ToShadow() data
```
`microservice #2`
```go
// get from RabbitMQ job with logParent.ToShadow() data
logChild := tracefall.NewLog(`prepare Scrapping`).SetApplication(`micro.2`)
logChild.ParentFromShadow(job.LogShadow)
```
Now `logChild` has parent `logParent`
## Use
**Create new Log node**
```go
import "github.com/efureev/tracefall"
// ...
log := tracefall.NewLog(`test log`)
```
**Finish log**
```go
log := tracefall.NewLog(`test log`)
// with fail result
log.Fail(err error)
// with success result
log.Success()
// without result: set finish time of the log
log.FinishTimeEnd()
```
**Finish thred of logs**
```go
log.ThreadFinish()
```
**Add extra data to Log**
```go
log := tracefall.NewLog(`test log`)
log.Data.Set(`url`, `http://google.com`).Set(`service`, service.Name)
```
**Add notes to Log**
```go
log.Notes.Add(`send to redis`, `ok`).Add(`send to rabbit`, `ok`)
//or
log.Notes.AddGroup(`send to redis`, [`ping`,`processing`,`done`])
```
**Sending logs to storage**
```go
var logStorage *tracefall.DB
func tracerLogStart(tracerHost, tracerUser, tracerPassword, tracerDbName, tracerTable string) {
var err error
logStorage, err = tracefall.Open(`postgres`, postgres.GetConnParams(tracerHost, tracerDbName, tracerTable, tracerUser, tracerPassword))
if err != nil {
log.Fatal(err)
}
}
func send(m) {
if logStorage == nil {
return
}
_, err := logStorage.Send(m *tracefall.Log)
if err != nil {
fmt.Println(`[error sent to trace logs] -> ` + err.Error())
}
}
```
