Welcome to This Week in Log Management!

Every week we get many great questions through support, the community, social media, and our weekly demo. On Fridays, I like to share the most common questions and answers, tips, insights, a closer look at Graylog, interviews, etc.

If you have any questions for me, drop them on Twitter, and I’ll do my best to fold them into upcoming Friday posts. Our handle is @graylog2.

What is your search query language? Do most people use the Web query to build searches?

The Graylog Web Search query is one of the most powerful features in Graylog and one of the easiest to use. The query interface uses something very close to the Lucene Syntax. In the web interface, the query syntax will enable you to build very fast, simple queries. For example, if you wanted to look in all of your logs for SSH logins throughout your logs. You can run a random search with “ssh” in it, and tada, you found it. You can run this search in all messages streams or by selecting a specific stream to narrow down your logs by stream. Once log data is returned, you can view everything that is found with “ssh”. Now you can find specific messages with messages containing “ssh login”. 

Using a specific term like “ssh login” in search will further narrow down the logs containing everything related to SSH logins.

If I am running the Open version, do I need to re-install to deploy the Enterprise version?

Installing Graylog on DEB, RPM, and Docker-based deployments allows you to upgrade your license with ease. If you prefer deployment of Graylog via configuration management tools, you can and currently is available with Chef, Puppet, and Ansible. OVA setups in an Enterprise environment are not suitable for production deployments out of the box. They do not have sufficient storage or offer capabilities like index replication that meet high availability requirements.
