Why are we unable to connect to Splunk Cloud from Mule?

[mragavan]

Hi,

I tried using HEC and configured log4j as mentioned below in Mule,
but I'm getting a connection timed out error.

<Http name="Splunk"
        url="https://***url****.com:8088/services/collector/raw">
        <Property name="Authorization" value="*****token****" />
        <PatternLayout pattern="%-5p %d [%t] %X{correlationId}%c: %m%n" />
    </Http>

Added following dependency in pom

<dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-core</artifactId>
        <version>2.10.0</version>
    </dependency>
    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-api</artifactId>
        <version>2.10.0</version>
    </dependency>
    <dependency>
        <groupId>com.splunk.logging</groupId>
        <artifactId>splunk-library-javalogging</artifactId>
        <version>1.7.1</version>
    </dependency>

Error:

Log4j2-TF-7-AsyncLoggerConfig--4 ERROR Unable to send HTTP in appender [Splunk] java.net.ConnectException: Connection timed out: connect

Any help is appreciated.

Hi @mragavan,

A time out usually indicates that a firewall could be blocking your connectivity.

Could you run the following see if you're able to get a connection : telnet HEC_IP 8888

Cheers,
