  how can show the log on console?

#################################### Logging ##########################
[log]
# Either "console", "file", "syslog". Default is console and  file
# Use space to separate multiple modes, e.g. "console file"
mode = console file

# Either "debug", "debug", "warn", "error", "critical", default is "debug"
level = debug

# optional settings to set different levels for specific loggers. Ex filters = sqlstore:debug
filters =

# For "console" mode only
[log.console]
level = debug

# log line format, valid options are text, console and json
format = console

# For "file" mode only
[log.file]
level = debug

# log line format, valid options are text, console and json
format = text

# This enables automated log rotate(switch of following options), default is true
log_rotate = true

# Max line number of single file, default is 1000000
max_lines = 1000000

I want to see client.go log with debug on console?but how ?I can not see these messages below.

	clientLog.Debug("Executing multisearch", "search requests", len(r.Requests))

	multiRequests := c.createMultiSearchRequests(r.Requests)
	res, err := c.executeBatchRequest("_msearch", multiRequests)
	if err != nil {
		return nil, err
	}

	clientLog.Debug("Received multisearch response", "code", res.StatusCode, "status", res.Status, "content-length", res.ContentLength)

	start := time.Now()
	clientLog.Debug("Decoding multisearch json response")

	var msr MultiSearchResponse
	defer res.Body.Close()
	dec := json.NewDecoder(res.Body)
	err = dec.Decode(&msr)
	if err != nil {
		return nil, err
	}

	elapsed := time.Now().Sub(start)
	clientLog.Debug("Decoded multisearch json response", "took", elapsed)

You'll need to upgrade to Grafana v5.2.0 first since Elasticsearch backend implementation was introduced there.

thank you , now I uphrade to Grafana V5.2.0 already. I build it with source code, I want to debug the backend code, I had config the .ini file with debug level ,but I can not see the debug message on console, I need some help now , thanks.

the backend is run by bra run

Can you tell me how to do? Thank you!

The elasticsearch backend code is only executed for evaluating alert rules at the moment. When you render graphs in Grafana the frontend code is solely used. We want to change this eventually and make it solely a backend implementation, but no idea of when this will happen.

I set level=debug in .ini file, bug the debug messages were not print on console?

How are you executing your elasticsearch queries? Thru alerting? As I wrote earlier you wont get any debug messages if you only render a graph in Grafana UI since the backend elasticsearch is not in play then.

[yue6121]

not alerting. Only query data from es.

[yue6121]

did client.go work when I query data from es?

Please read my comments. You wont get any debug messages if you only render a graph in Grafana UI. You need to create an alert rule and when that alert rule is evaluated the backend elasticsearch code will be executed and you'll see debug log messages.

I got it, Thanks a lot!
