### "Graylog Enterprise Log for Business"

September 12, 2021

5.0

prevously we using syslog server to centralize log, and when we have more server and network we can not put all those log into syslog server that store data in mysql, it perform slow search and not report correctly, i have try spend sometime to search and i found graylog, i try to setup a few day until success because its new related to elastic search, but finally i find out and keep using until now, its around 3 years already since i use graylog server to monitor all the network activity, monitoring server with nxlog agent, monitor cisco switch with syslog, linux with syslog, and can monitor the radius authentication log, each time users plug the network or connect wifi log generated and sent to graylog-server, and graylog server create alert message send by telegram to system admin.

Pros

\- Graylog is very powerful log, i have search around 50million of record in 3second only, very powerful log because it integrated with elastic search that perform log search very fast. - Telegram alert notification is what i like, i create the rule to let it send notification to telegram so i know what is going on on the network/server log. - enterprise license are free for one year, and make sure your traffic log not hit to 5GB/day. - support various log protocol, nxlog from windows, syslog from linux, and other such as aws. but i use only nxlog and syslog only.

Cons

its perfect already but the dashboard not so nice, not so flexible on the reporting yet.

Reason for choosing Graylog

normal log search server support only syslog protocol, its not enough and not detail information. well, graylog is enterprise class, license cost is cheaper than other, fast search, support multi protocol of log, from windows server, linux, aws, and more protocol, but based on my experience and real work with graylog is we use graylog to store windows log, linux, cisco, mikrotik, fortigate, unifi router, dell server, dell SAN storage, and dell core swithc only. currently we have around 300 devices that sent log to graylog server, and log traffic around 3GB/day, but graylog can perform search the log information well even the database of graylog is 500GB for 6months, as we always archive the database when it increase to 500GB of log.

### "Great value to cost ratio for a solid log management solution"

November 2, 2020

5.0

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.

Alternatives considered

[Sumo](https://www.capterra.com/p/175695/Sumo/)[Splunk Enterprise](https://www.capterra.com/p/94317/Splunk/)

Reason 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.

Switched from

[Splunk Enterprise](https://www.capterra.com/p/94317/Splunk/)

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.

### "You can’t do better for building a Log Management Ecosystem"

July 5, 2020

5.0

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.

Reason 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.

### "Very strong on open source on-premise solution"

June 25, 2020

5.0

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.

### "Incredibly flexible open source log management tool"

October 7, 2019

5.0

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.

Reason 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.

### "Graylog the best syslog"

September 4, 2024

5.0

I use Graylog for security and GDPR purposes. Speaking about security, it helps me a lot, I collect logs from firewall, nas, switch, windows (e.g. Domain Controller and Terminal Server) and linux server, especially if they are published on internet. If you have an exchange on premise you should collect the log files under inetpub directory (use the windows filebeat). I can download report in excel format. Updates are frequent. A great product you should try.

Pros

You can choose the free version and have all the features needed to collect and look for logs. There is a huge community, so in case of need you will easily find the answer to your question/problem. The interface is simple and you can create your own dashboard with tables, graphs and counter (you can view your logs and create tables also with graphana, using elasticsearch as data source). You need to add at least an input, it can be for example an UDP one or for windows and linux machine filebeat on port 5044 (via sidecar). You will see your sidecar devices on the Sidecars section. You can create and save queries using lucene language, they will help you to find any potential threat logged. Graylog server runs on a Linux Machine, installation is quite easy, there are lot of tutorials on internet.

Cons

some features are only on enterprise edition, the purge of inactive sidecar sometimes does not work (you have to restart graylog-server service)

### "Graylog the king of syslogs"

July 15, 2024

5.0

Graylog has a clean interface that I like very much. I keep monitored several devices and I created many queries that look for unusual activities. I run and keep updated many Graylog server installations and they work fine. Just remember to se the right number of indices and their rotation to avoid loss of data if disk becomes full. Collecting logs is also useful for GDPR purposes. Among Syslogs i think Graylog is the best one.

Pros

Graylog can be totally free, and you can collect logs from windows and linux systems and from other devices such as firewalls and switches (there are many more). You need a linux machine to install and run graylog server. With Windows and Linux you have to install Sidecar and Filebeat to collect data and configure the agent. You can create many indices and set their retention policies. Once you start collecting logs you can do searches with lucene query, and save your queries. Then you can download the results in .csv format. With Graylog you can create dashboards, set alerts (e.g. via email or via telegram) that help to keep your network safe, remember to set the right path of logs in your Winlogbeat and Filebeat.

Cons

Some installation guides are not really clear.

### "Great piece of software"

September 25, 2020

4.0

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.

Reason for choosing Graylog

We considered ELK for this but the amount of available inputs made us to choose Graylog.

### "Windows Servers Events Agreggation "

July 28, 2020

4.0

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)

Reason 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.

### "Logging done right"

June 24, 2020

5.0

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 features and a dedicated staff."

June 16, 2020

4.0

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.

June 24, 2020

5.0

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.

They do have one of the best log data visualization tools

Pros

Cons

It was difficult to get started with Graylog because I mostly use software documentation to set up new software but apart from the basic "how it works", I got a little lost. They should improve on their documentation and provide support
