You can’t do better for building a Log Management Ecosystem
I’ve recommended it as a solution to many local governments during my conference presentations and they’ve listened.
Pros
Graylog is built on ElasticSearch and extends its functionality out into a great product with the System Administrator in mind. You stand up the platform, point logs at it and the rest is up to your internal processes. I also enjoy that the vast majority of intelligence and augmented data is built directly into the platform rather than an outside product. The community support forums are chock full of helpful folks.
Cons
For a long time the visualizations were quite lacking and we required additional tools to properly tell our data stories but this is improving drastically with each new release.
Reasons for Choosing Graylog
Cost and simplicity. Also, you can leverage any aspect of ElasticSearch that you desire as well making it a very versatile choice.

Great value to cost ratio for a solid log management solution
Graylog has been great to work with. Their sidecar implementations make client configuration and management very easy, and even with the free version, they provide reliable, albeit limited support (I’ve gotten good, live email replies to a couple of questions, versus only allowing you to access forums, etc).
Pros
Very low cost of ownership, particularly if you can get the Community (Free, Open-Source) version to meet your needs. I’ve implemented Graylog at multiple organizations for only the cost of hardware / storage.
Cons
Would love to have more plugins / content packs available in the Graylog Marketplace. With limited hands on a team for a smaller company, there’s often not enough time to write extractors and content packs.
Reasons for Choosing Graylog
Again, of note, we didn’t purchase. While there’d be added value to enterprise plugins and support, we are meeting our needs with the Community (F.O.S.S.) version.
Reasons for Switching to Graylog
Cost associated with using the tool, based on data ingestion, was going to substantially increase our expenses to even maintain the solution as it stood. This was the case at multiple organizations, as well.

The customer support structure needs to improve, we have been facing unknown issues for which rca was needed however there have been issues. The streams were showing running but they were struck. Also option should be there to easily search logs

One of The Best Log Management Tools in Market
Pros
Amazing documentation & really easy deployment made life easier for me. Data search also I found really easy & I have tried multiple products but graylog probably the most easiest one to follow
Cons
Nothing much so far. It has been great for our company
Reasons for Choosing Graylog
Cost & better search. Also i found graylog better integrates with our current infrastructure too

Very strong on open source on-premise solution
Experience has been great, we started by using the free version, it has provided benefits early on to the dev teams to search through web logs without the need for downloading them and using a log parser application, or committing early to expensive paid tools. Since then we keep adding new sources and are looking at more enterprise features as usage grows.
Pros
Graylog has alot of flexibility and a mature feature set. We use it across all of our Windows as well as Linux servers. It has a strong community and alot of flexibility, does not impose restrictions on our applications, good documentation and generally receives regular updates and features.
Cons
I find some of the latest changes to the GUI (changes happen all the time with Graylog) are less user friendly - functionality to get count tables are still there but it is less dummy proof whereas before a novice user could click around in the side navigation and discover certain features. There are also less cloud offerings for Graylog so it fits more the on-premise model where you manage the graylog server/infrastructure.
Reasons for Choosing Graylog
We had a senior team member that had experience with Graylog.

Incredibly flexible open source log management tool
I am a data analyst so I often deal with large amounts of data that are really complicated to parse and sort through. I used Graylog to aggregate and parse logs which I later analyzed for relevant information.
Pros
Graylog is a fantastic tool to summarize and aggregate data into simple and highly accessible visual depictions and dashboards. Although it is an open source log management solution, it is really flexible and agile, and helps me parse data rapidly and intuitively. I think it's one of the best alternatives to Splunk - and probably is a much better tool even for enterprises.
Cons
Learning curve is a little bit steep. You need a somewhat technical background to learn it, but once you grasp the basics, it is way less cumbersome than others such as Alienvault or Loggly.
Reasons for Choosing Graylog
Splunk conduces its searches via a formal query language. Since I didn't know it, it was really hard to extract meaningful insight from aggregated logs that spanned across many different categories.

Logging done right
I love the product. I spread the word everywhere I go because I believe it has a future in the undustry.
Pros
Traditionally every IT/MSP business will use some sort of system to log data from all inputs. What I hated the most about other systems was that they really didn't improve on what was given to them (meaning logs). They either just held the logs or perhaps told me about errors I already knew. With graylog, we were able to get a wealth of additional info. Sure it requires some work writing extractors or pipelines, but at the end you get exactly what you are looking for. And with the available plugins, you can take what you had and improve. Simple example, in the past I would get an email of all errors but now I can get an email, Slack or push it as a ticket via API. Another great feature is the side-car addition. No more managing configs individually, you can manage and maintain the configs all from graylog. My wish is to introduce native plugins for other SaaS products. Recently they added ability to inject Okta logs. How about Cisco Duo or Umbrella. Both are in hot demand right now, might as well get that data too.
Cons
It's great at what it does but it does have some limitations. Dashboards and graphs are not as flexible as lets say Grafana. Not that it should be, but if someone wants a pure dashboard system then this may not be for them.

Great piece of software
Great piece of software, all our applications and cloud provider logs are being sent to graylog. Very easy to filter and review the logs. Their staff is nice, they're always grateful to help with doubts and giving support to OSS contributors.
Pros
All in one product. Lot of inputs available so you can ingest logs from a wide range of applications. Pipelines are a powerful tool to normalize data before indexing.
Cons
UI used to look "old". Now is getting much better but it still needs more love. The "single" designated master is not very cloud friendly. I'd like some kind of automated cluster management (with quorum to elect the master node) so we don't have to manually set one node as master while keeping our scaling operations.
Reasons for Choosing Graylog
We considered ELK for this but the amount of available inputs made us to choose Graylog.

Hi Marc, Thanks so much for taking time out to leave us a review. Glad you find the variety of inputs useful. We have shared your suggestions with our product team and they will definitely consider them. Thanks, Team Graylog

Windows Servers Events Agreggation
My overall experience is very grafull, since i didn´t know anything about Graylog / Elastic Search, it´s been an adventures. Tears and Joy, may hours in deep community forum and documentation. Since then, audit active directory, filesharing, is been very easy to search.
Pros
We use graylog for Windows Server Events (Event Viewer) in one place, it´s very usefull. The Alert Setup and new features like Pipelines (For disclose unknown error codes) is one plus in the Graylog. The other Pro is the community forum and support. Theres a VDA version ready to use. (Ubuntu) Free Enterprise Licence with Traffic limitation ( normaly for one server / event aggregation)
Cons
If you need to custom setup with several graylog nodes is hard to get it running in the first try. Some nice features are only available in Enterprise Edition. No backup for Indexes is available , need to use external options. Very hard post-config and clean the logs for the right information (need work)
Reasons for Choosing Graylog
Main the only one with no limits for free edition in terms of traffic / machines ... The Dashboards and the query agreggation made the job very easy afterwords.

Enterprise grade log management
I started with free version several years back and grew the cluster into multiple nodes. Product itself is solid and easy to maintain. Keep the documentation in sync with new features.
Pros
Initial deployment is well documented but after that it's up to the admin to figure out how to utilize the software.
Cons
Complexity grows with deployment size, which is expected from such software. Adding more predefined dashboards would save time for new admins while providing examples how to best utilize graylog.

Great features and a dedicated staff.
I haven't used Graylog for logging of large enterprise systems so I can't how it performs in those cases, but I do like the DIY feel for smaller projects. It is very customizable and easy to configure things how you like.
Pros
I like Graylog because of how easy it is to get logs flowing into the platform. Most of my experience has been with the AWS Cloudtrail plugin, but syslog wasn't hard either. The documentation works for most typical cases. I also love the new update! The dashboards are beautiful and it's easy to get any statistic you want. It's come a long way which shows dedication and a want to always be improving.
Cons
Most typical use cases are covered by the documentation, but if it isn't it can take some searching to figure out if there's a way to accomplish your goal. I have no experience with the enterprise or community support so I can't say how much that might help.

Great Solution for Log Collection
A complete solution when collecting log streams and alerting based on them.
Pros
Its a good solution when comes to log collecting and alerting based on the metrics. It can use for send notifications through mail, slack etc.
Cons
Implementation was hard. There were issues within the log retention setup and sometimes had to rotate manually.

Graylog used as a platform for performance monitoring
Pros
We have integrated graylog with a ES cluster and used beats forwarders to send performance metrics from a server cluster. So from a single interface we were able to setup log settings for multiple inputs. Also the grok patterns were very useful for incoming message processing.
Cons
Would like to have few more dashboard options. Some panels like Kibana dashboards.

Logging and alerting all in one place
Pros
The most that I like about this software is that it keeps all of our application error logging all in one place and we use it to set up alerting policies whenever we get more than 5 errors in a minute or so. This allows us to get our engineers on the problem and fix it as soon as possible instead of waiting until a end-user reports an error which is not proactive.
Cons
The least thing that I liked about the software was the way that it collects the logs, you need to send your logs in a specific format for Graylog to consume so that may take writing a small application or script in the middle to parse and format your logs over to Graylog in the correct format.

Graylog-One stop for centralized log management
Overall, Graylog was serving the purpose of centralized log management solution. Easy to install with ELK stack to improvise the log server architecture. We were able to implement a centralized log management with GUI and sent filtered logs to SIEM which saved cost of SIEM license and enhanced security incident management.
Pros
Integration with multiple log sources and log filtering.
Cons
Alert notification based on correlation of log parameters feature is missing.
Reasons for Choosing Graylog
Easy installation and migration to licensed version.
Reasons for Switching to Graylog
Kiwi Syslog was not having filtering features.

Great product but could use some additional documentation and examples
Overall the product is great and you can get away with a lot without having to purchase a license.
Pros
Open source, scalable, efficient, many powerful features, accepts all sorts of inputs for logs, open marketplace for users to share their content packs
Cons
Large scale deployment documentation is missing (sure they give you ideas but it could really use a how to article or video). Could use some of the features from kibana.

Easy to set up and use
When I needed to get logs into one centralized location for reading and understanding, graylog accomplished this when others couldn't.
Pros
Compared to other products of similar nature, I found graylog to be the easiest to setup and deploy, even on a limited VM. It's surprisingly well put together and can run even on a resource limited virtual machine.
Cons
The interface could be a bit nicer, maybe it has improved since I last used it, but that's the only issue I had with it.
