Solarwinds® Kiwi Syslog® Server is a syslog management tool for network and systems engineers. It receives syslog messages and SNMP traps from network devices (routers, switches, firewalls, etc.), and Linux®/Unix® hosts. Users can filter and view these messages based on time, hostname, severity, etc., and set up custom alerts. Kiwi Syslog Server has built-in actions to react appropriately to syslog messages. There are also log archival and clean-up features to help comply with security policies.
If you already have a basic understanding of Elasticsearch and/or MongoDB, Graylog will be a great fit when it comes to log aggregation. It will be a decent option even if you don't have any experience but have the time and willingness to roll up your sleeves that learning those tools will require. Graylog supports plugins to extend functionality for things like SNMP traps, telemetry collection, and solar flares. As is the case with most software with plugins, if the core functionality for which you are looking (i.e. not logging) is based on a plugin, Graylog probably isn't for you. The majority of the plugins in the marketplace are developed by third-parties looking to solve their specific use case so bug fixes and new features are not a given.
The SolarWinds Kiwi Syslog Server does what it's supposed to do. It's a bare-bones Syslog Server. If your company is just trying to fulfill security requirements or doesn't need all the advanced features of a product such as Splunk, then Kiwi will work well and not break the bank. Using the tool is very straightforward as there aren't a lot of options outside of just viewing logs.
Collection of SNMP traps a reliable and stable collection server for these is crucial to troubleshooting and time to ROS. Kiwi excels at this.
Easy to install set up and train users on.
The free version is a good free tool and handy to use for personal labs and other smalle use cases.
SNMP traps to user readable format is great, sometimes syslog and smnp messages can be hard to interpret and read with out a knowledge of how to do this.
Kiwi Syslog has the best usability of any syslog server. While not being able to offer the most features, the ones it does have are intuitive and easy to work with. Everything that it has is where you think it should be. If you can't find it in the menus, it doesn't exist.
I am still unhappy with the pricing model for the enterprise. Graylog competes against the likes of IBM and Splunk, but your still the new kid on the block. To price Graylog enterprise at 50k for 20GB ingest an unrealistic data. It would require multiple facets of Graylog to be stood up and only forward pruned logs to the paid version.
Because the solution is so simple to use and implement, support wasn't very necessary. The one time I did call them to better understand where logs were stored, they were very helpful and friendly. Kiwi has been around for some time and not a lot has changed over the years, so support for it is pretty straightforward and quick.
Azure Monitor is not exactly what I mean, but I couldn't find Azure Application Insights. Anyway, for a large organization, Azure makes more sense than using Graylog because a lot of logging will already be inside Azure. And you don't want to have two "central" logging locations. But Azure is chaos and highly "not intuitive." So for small and mid-size organizations, Graylog is still the better option.
Syslog-ng don't have customer support or technical support .But its a free software and no clarity on limitations ingestion bandwidth. No gui feature and everything should be done from backend. Gui can easily help to start and stop service ,easy to configure. Unlimited technical and customer support . Even when server got shutdown will get on-call or immediate support that will helps a lot to resolve errors
