The regular expression based log parsers work really well. Immediate discovery of issues helps fixing the bugs very soon. You do not need to login to server and check the logs everytime. Logstash along with Kibana and elasticsearch works like a charm. You will get a holistic view of all your logs and your debugging starts here. Review collected by and hosted on G2.com.

Its parsing is limited to the regular expressions. Should have some approximate matching with ML techniques which can help discover more issues. Writing custom grok regex patterns is a bit complex. The threshold for one time setup is a bit high and you need to have an initial understanding of the tools. Review collected by and hosted on G2.com.

I enjoy being able to query my data out of the logs and quickly find resolution to the issues in the platform. I also enjoy the auto highlighting of the search fields so that I can quickly determine if I am going down the right path for the errors located in the logs.

Sometimes the filter build is a bit too complex when you want to just create a simple text search. Since I'm not in there everyday I tend to forget the tricks to traversing the logs quickly Review collected by and hosted on G2.com.

It's a very versatile log processor with a very supportive community. It also comes with ample of plugins that's very useful. The GROK filter plugin contains prebuild regular expression that supports common software log patterns to get you up and running quickly. Review collected by and hosted on G2.com.

There is a learning curve like all software. It has its own syntax and requires java run time. It's a memory hungry software for being a java app. Review collected by and hosted on G2.com.

This product was hard to get used to coming from SQL based querying and storage, but this product storage was so much more useful for the twitter data we used to store in it. Review collected by and hosted on G2.com.

It was confusing because of the document based storage, which was strange. Review collected by and hosted on G2.com.

It gives all the info on single dashboard and can be customized to get api response time metrics like average response time for a specific duration.You can see how many calls were made during that time and min,max and average response times Review collected by and hosted on G2.com.

When I get to raw data it does open one excel sheet st a time and you need to close all other instances Review collected by and hosted on G2.com.

The tool is powerful, free and very easy to install. The documentation is wonderful. Well written and complete. Review collected by and hosted on G2.com.

Nothing. Perhaps it is not in its maturity stage. They are releasing new major versions and it can be a problem. Review collected by and hosted on G2.com.

Kibana's UI is very intuitive and performant, filtering tools available are also very easy to use and make operational tasks like troubleshooting issues and scanning logs very efficient. Review collected by and hosted on G2.com.

The query language takes a little bit to get used to Review collected by and hosted on G2.com.

Very supportive community to reach out with issues. I also like their grok feature to do basic regex searches to convert some of my unstructured data into structured data and gives more visibility into my application logs.

Last but not least, it's open source so it’s simple to extend it to custom log formats or add plugins for custom data sources. Review collected by and hosted on G2.com.

It took me a while to set Logstash correctly and run it reliably without running into any issues. I would often get out of memory issues and even after increasing system RAM, I would run into this issue. I finally figured out the issue after much searching around but it was not immediately clear what caused the issue. Documentation is good but as with any open source tool, it is not as extensive or complete as one would wish. Review collected by and hosted on G2.com.

Very easy setup.

The fact that it is open source is always a plus.

Good user guide which is very helpful and a must read to know how to use Kibana and all of it's features. Review collected by and hosted on G2.com.

Poor performance when there are a lot of logs to search through. The max tolerable search we can use is "This Month". Anything over that and it is just very long for the results to load.

Need to read the user guide or else it's hard to know what your doing and the best way to search through all your logs. Review collected by and hosted on G2.com.

The Logstash solves my problem. It collects all my logs and stores it in ElasticSearch. Everything else I do not like in this product! Sorry guys but other products from your company is much better! Review collected by and hosted on G2.com.

I don't like the following:

1) Why Java and Ruby? Why not just Ruby or Java? I have to configure how to run java, jruby and after that I faced with the Ruby errors of some plugin... AAA!!

2) I don't understand configuration, what should i chose: embedded Elasticsearch or dedicated? What is the differences? Why some of plugins may be input, output, and filter? What should I chose?

3) I've configured Logstash, but I still have a lot of misunderstandings.

I would like to have interface to configure Logstash in the Kibana. Review collected by and hosted on G2.com.
