# Stackdriver sample for Google Compute Engine
2+
This sample demonstrates how to use [Stackdriver](https://cloud.google.com/error-reporting/) on Google Compute Engine
3+
## Running on Compute Engine
4+
1. Create a compute instance on the Google Cloud Platform Developer's Console
5+
1. SSH into the instance you created
6+
1. Update packages and install required packages
7+
sudo apt-get update && sudo apt-get install git-core openjdk-8-jdk maven
8+
1. Follow the instructions to [Install the Stackdriver Logging Agent](https://cloud.google.com/logging/docs/agent/installation)
9+
1. Create /etc/google-fluentd/config.d/forward.conf and add
10+
<source>
11+
type forward
12+
port 24224
13+
</source>
14+
1. Restart the logging agent
15+
sudo service google-fluentd restart
16+
1. Clone the repo
17+
git clone https://github.com/GoogleCloudPlatform/java-docs-samples.git
18+
1. Navigate to the Stackdriver sample folder
19+
java-docs-samples/compute/stackdriver
20+
1. Make sure that openjdk 8 is the selected java version
21+
sudo update-alternatives --config java
22+
1. Use maven to package the class as a jar
23+
mvn clean package
24+
1. Switch to the target folder and execute the jar file
25+
java -jar compute-stackdriver-1.0-SNAPSHOT-jar-with-dependencies.jar
26+
1. On the Developer's Console, navigate to Stackdriver Error Reporting and verify that the sample
27+
error was logged.
