Does Apigee support Graylog for message logging. if I give just the IP and port for the message logging policy, will it work in apigee for graylog. I understand for graylog to work, we need to install logstash in the client side, but I am not sure, what has to be done in edge side. Can anybody help me here.

@krushna.padhee.ap : Apigee can support logging to an external Log System over HTTP

STEP-1 : Configure a GELF HTTP listener on Graylog. Please refer Graylog docs for configuring incoming data [http://docs.graylog.org/en/2.1/pages/sending_data.html](http://Graylog Configuration Doc)

(http://Graylog Configuration Doc)

STEP2: Test GELF Listener is getting data over HTTP. Refer a Postman screenshot

STEP3 : Configure a Service Callout in an Apigee Proxy to Send Apigee Proxy Logs over HTTP to Graylog. Refer following code for Service Callout configuration

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ServiceCallout async="true" continueOnError="false"enabled="true" name="Log2Graylog">
    <DisplayName>Log2Graylog</DisplayName>
    <Properties/>
    <Request clearPayload="true" variable="myRequest">
        <IgnoreUnresolvedVariables>false</IgnoreUnresolvedVariables>
        <Set>
            <Payload contentType="application/json" variablePrefix="@" variableSuffix="#">
                {"event":"Logged from EDGE"}
            </Payload>
            <Verb>POST</Verb>
        </Set>
    </Request>
    <Response>calloutResponse</Response>
    <HTTPTargetConnection>
        <Properties/>
        <URL>http://192.168.1.13:12201/gelf</URL>
    </HTTPTargetConnection>
</ServiceCallout>

STEP4 : Graylog will Display Messages in the configured HTTP listener as shown Below

Incase you need to integrate with other popular logging systems like Splunk , you may refer following community articles and docs

Splunk :https://community.apigee.com/articles/13298/log-messages-into-splunk.html

Hi Saurabh,

I found one limitation, the service callout policy which is not allowed to have in response flow in apigee edge, in that way, I can’t log my error logs from the response. Do you have any solution for that.

@krushna.padhee.ap That’s not true Krushna. You can use service call out policy in any flow except the PostClientFlow.
