Avis clients sur Graylog

Graylog Enterprise Log for Business

Commentaires : 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.

Avantages :

- 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.

Inconvénients :

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

Great value to cost ratio for a solid log management solution

Commentaires : 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).

Avantages :

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.

Inconvénients :

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.

Graylog software review

Commentaires : They do have one of the best log data visualization tools

Avantages :

I can customize the log data that will be visualized the way I want it and the analytics are mostly a true reflection

Inconvénients :

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

Graylog the best syslog

Commentaires : 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.

Avantages :

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.

Inconvénients :

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

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

Commentaires : I’ve recommended it as a solution to many local governments during my conference presentations and they’ve listened.

Avantages :

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.

Inconvénients :

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.

Very strong on open source on-premise solution

Commentaires : 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.

Avantages :

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.

Inconvénients :

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

Commentaires : 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.

Avantages :

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.

Inconvénients :

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.

One of The Best Log Management Tools in Market

Avantages :

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

Inconvénients :

Nothing much so far. It has been great for our company

Graylog the king of syslogs

Commentaires : 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.

Avantages :

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.

Inconvénients :

Some installation guides are not really clear.

Great piece of software

Commentaires : 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.

Avantages :

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.

Inconvénients :

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.

Best and most popular open-source log management tool

Commentaires : Overall, Graylog is a powerful and an outstanding Software , I recommend it to users

Avantages :

I love this software for it's amazing performance, Graylog provides real-time log analysis, enabling you to identify and respond to potential issues quickly.

Inconvénients :

I haven't encountered any deficiency using Graylog

Logging done right

Commentaires : I love the product. I spread the word everywhere I go because I believe it has a future in the undustry.

Avantages :

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.

Inconvénients :

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.

Windows Servers Events Agreggation

Commentaires : 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.

Avantages :

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)

Inconvénients :

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)

Great features and a dedicated staff.

Commentaires : 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.

Avantages :

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.

Inconvénients :

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.

Enterprise grade log management

Commentaires : 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.

Avantages :

Initial deployment is well documented but after that it's up to the admin to figure out how to utilize the software.

Inconvénients :

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.

Graylog support

Avantages :

Its easy to use and deploy. We have installed it over centos and its easy to deploy and start working on.

Inconvénients :

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

Great Solution for Log Collection

Commentaires : A complete solution when collecting log streams and alerting based on them.

Avantages :

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.

Inconvénients :

Implementation was hard. There were issues within the log retention setup and sometimes had to rotate manually.

Find it, fix it..

Avantages :

Fire as many log files in to Graylog as you can find across your infrastructure, whether it be Linux, Windows or hardware. Fine grain search, alerts and actions are at your fingertips in milliseconds 😁

Inconvénients :

Not really any downsides.. as long as you have enough storage!

The possibility of centralizing logs, besides being able to create deshboards

Inconvénients :

Difficult to configure and manage, confusing

Great software that keeps improving

Avantages :

Meets all of our logging needs and is very customizable. Community Edition is a great introduction to Graylog.

Catching up on the latest updates can be a pain.

Graylog

Commentaires : Very good, we needed to collect our application logs for an audit, Graylog does the job perfectly!

Avantages :

Very easy to send logs to Graylog and collect them using sidecar.

Building dashboards takes some time to understand, check out the marketplace for them

Excellent log management platform

Commentaires : Great log management platform, extremely flexible.

Avantages :

Multiple deployment options Powerful log parsing and dashboarding features Open source (for the most part)

Inconvénients :

Some great features are exclusive to the paid tier.

Great product but could use some additional documentation and examples

Commentaires : Overall the product is great and you can get away with a lot without having to purchase a license.

Avantages :

Open source, scalable, efficient, many powerful features, accepts all sorts of inputs for logs, open marketplace for users to share their content packs

Inconvénients :

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.
