Talk: Using Logstash and Elasticsearch Together

Sematext engineer and Elasticsearch / Logstash expert Rafal Kuc is giving a talk about using Logstash and Elasticsearch together at DevOps Days Warsaw on September 26.  The talk is titled “From zero to hero: easy log centralization with Logstash and Elasticsearch” and it will be livestreamed and available afterward as a video. Details will be posted here and @sematext in late September.

Here is the common logging problem that Rafal is going to address: digging through logs to find one particular event — or group of them. And going even further into this pain point — what if you have lots of servers and you don’t have a single place to look for logs?  Let’s face it, you can end up spending hours digging through log files to find events you are interested in and manually correlating them with events from different sources.  If you have read this far into this post then chances are you have been there, done that.

And here is how Rafal’s talk could benefit people working with Logstash and Elasticsearch: he is going to guide attendees/viewers through the basics of using Logstash and Elasticsearch together as the perfect combination for handling logs from multiple applications.  So if you want to see how Logstash + Elasticsearch can help you, this is a great opportunity to do so.  Attendees/viewers will learn how to set up Logstash, how to configure it to parse logs and, finally, sending them to an Elasticsearch cluster.

Rafal will also discuss tuning Elasticsearch for log management and centralized logging purposes, and show how to easily switch between shipping logs to a self-hosted solution like Elasticsearch / Logstash / Kibana (ELK) and instead ship logs to Logsene Log Management and Analytics by changing a single line in Logstash configuration.

Last but not least — Rafal should be at the event both days (September 25 & 26).  So if you are going to attend in person and have some Logstash and/or Elasticsearch topics you’d like to discuss with an expert, then reach out to him on Twitter – @kucrafal

JOB: Elasticsearch / Lucene Engineer (starts in the Netherlands)

In addition to looking for an Elasticsearch / Solr Engineer to join the Sematext team, we are also looking for an Lucene / Elasticsearch Engineer in EU for a specific project.  This project calls for 6 months of on-site work with our client in Netherlands.  After 6 months the collaboration with our client would continue remotely if there is more work to be done for the client or, if the client project(s) are over, this person would join our global team of Engineers and Search Consultants and work remotely (we are all very distributed over several countries and continents). This is a position focused on search – it involves working with Elasticsearch, but also requires enough understanding of Lucene to allow one to write custom Elasticsearch/Lucene components, such as tokenizers, for example. Here are some of the skills one should have for this job:

  •  knowledge of different types of Lucene queries/filters (boolean, spans, etc.) and their capabilities
  •  experience in extending out-of-the-box Lucene functionality via developing custom queries, scorers, collectors
  •  understanding of Lucene document analysis in the process of indexing, experience in writing custom analyzers
  •  experience in mapping advanced hierarchical data structures to Lucene fields
  •  experience in scalable distributed open-source search technologies such as Elasticsearch or Solr

The above is not much information to go by, but if this piqued your interest and if you think you are a good match, please fix up your resume and send it to jobs@sematext.com quickly.

Berlin Buzzwords 2014 – Side by Side with Elasticsearch and Solr

Last year at Berlin Buzzwords two Sematext Engineers had the opportunity to give two talks. Radu talked about “JSON Logging with Elasticsearch” (video, slides) and Rafał did the second round of Solr vs Elasticsearch in his talk “Battle of the Giants, round 2” (video, slides). We were also happy to be sponsoring Berlin Buzzwords 2013. This year, we decided to go for a talk where two of us can talk on the same stage, at the same time. On Tuesday, 27th of May, at 11:30, in the Frannz Club Radu and Rafał will be giving a talk called “Side by side with Solr and Elasticsearch“.

side by side

Solr – established, mature and well known open-source search server, commonly used. Elasticsearch – still young, but quickly gaining popularity, with over 200k downloads per month. Both search servers are based on Lucene – the open-source full text searching Java library, but each with their own extensions, their pros and cons.

We all know that Solr and Elasticsearch are different, but what those differences are and which solution is the best fit for a particular use case is a frequent question. We will try to make those differences clear, not by showing slides and comparing them, but by showing on online demo of both Elasticsearch and Solr:

  • Set up and start both search servers. See what you need to prepare and launch Solr and Elasticsearch.
  • Index data right after the server was started using the “schemaless” mode
  • Create index structure and modify it using the provided API
  • Explore different query use cases
  • Scale by adding and removing nodes from the cluster, creating indices and managing shards. See how that affects data indexing and querying.
  • Monitor and administer clusters.  See what metrics can be seen out of the box, how to get them and what tools can provide you with the graphical view of all the goodies that each search server can provide.

If you want to come, hear about both Solr and Elasticsearch from @sematext and how to achieve similar things, what how they behave and don’t see too many slides, come join us :)

Elasticsearch Server by Rafal Kuc & Marek Rogozinski – now updated!

Use Elasticsearch now?  Thinking about using Elasticsearch?  Wish there was a comprehensive resource that pulled everything you ever wanted to know about Elasticsearch together in one place?  Fret not — you are in luck!

All Elasticsearch, all the time

Sematext engineer Rafał Kuć has co-authored (with Marek Rogozinski) not one, but two(!) different Elasticsearch books: Elasticsearch Server and Mastering Elasticsearch.  Considering that Elasticsearch has only been around a few years — not to mention how much is going on under the hood — it’s a pretty impressive accomplishment.  Even more impressive?  Rafal and Marek have just published a second edition of Elasticsearch Server that encompasses all the changes between Elasticsearch 0.20 and 1.0.  So if you wish you knew more about Elasticsearch, look no further.

Here’s a brief Q&A with Rafal to add some insight:

Q:  What has changed since the first edition of Elasticsearch Server?

A:  After releasing the first edition of the book, which happened to be the first book about Elasticsearch, we got a nice amount of comments and suggestions which we took into consideration when writing the second edition.  The first edition was based on Elasticsearch 0.20, so we already had a lot of material to work with when we were asked to write the second edition and take readers up to version 1.0.  Some of the features we decided to write about were aggregations, new function queries allowing extensive score control, snapshotting, and others.  Some features that are still used by Elasticsearch users, like faceting, did not need much updating.  But others, like percolator, had to be completely rewritten.

Q:  How much work was it?

A:  We tried to make the book as good as we could so the readers could enjoy it and learn from it.  And believe me, we both learned a lot during the writing of the first edition of the book and while writing Mastering Elasticsearch. We had a lot of comments both from the readers and from people working on the book’s Japanese translation.  Thanks Jun!

We incorporated all the comments and suggestion, but it took time, of course. We also wanted to fully restructure the book so that it flowed better.  Hopefully we achieved that. Of course, in addition to all that we had to rewrite major parts of the book to bring it up to date, review all the parts that we decided to leave in the book and make updates as needed, and then write the new sections.

Q:  Where can someone buy it?

A:  You can buy it from Amazon or direct from Packt Publishing.
