For small companies, Graylog is the best solution possible. It's easy to configure and "just works." Above everything else, it's free. The only thing I hold against it is the fact that it's Linux-based. [This] makes sense because Elasticsearch is Linux-based. But Linux adds a layer of complexity that we don't need for something basic as a logging server. I'm pretty sure that we would have had a logging server years earlier if I had to convince quite a few decision-making people to go ahead with it anyway.

Zabbix is very well suited for infrastructure monitoring i.e. the underlying host servers, basically, compute nodes. However, it has limited FM & PM capabilities for the workloads, i.e., the virtual machines (VMs). Zabbix has an easy-to-use GUI which can be explored easily & provides good filtering of the data.

The backend for storage is Elasticsearch and MongoDB is used to store the configuration. You have to option to make your configuration as simple as possible by storing everything on one box, or you can scale everything out horizontally by using a cluster of Elasticsearch nodes and MongoDB servers with several Graylog servers pointed to all the necessary nodes. Graylog does a good job of abstracting away a fair portion of Elasticsearch index management (sharding, creation, deletion, rotation, etc).

Flexible design - It is very easy to build out even very large environments via the templating system. You can also start where you are - network monitoring, server monitoring, etc. and then build it out from there as time and resources permit. Provides a "plugin architecture" (via XML templates) to allow end users to extend it to monitor all kinds of equipment, software, or other metrics that are not already added into the software already. Very complete documentation. Almost every aspect of Zabbix has been documented and reported on. Cost - Zabbix is FOSS software and always free. Support is reasonably priced and readily available. Read full review Cons Support for more log sources Event alerts/emails - Some cases where unable to separate data from multiple clients, and no easy fix API - Limits results to 10,000 and can cause server to lockup on queries that exceed the limit Read full review In a busy Zabbix environment, it can easily overwhelm the underlying database. Plan on having SSDs and a significant server infrastructure to keep up with more than a hundred hosts. Building out Zabbix metrics that suit your environment can be very time consuming. When choosing a monitoring platform like Zabbix, expect a steep learning curve and to invest significant resources to make the tool valuable. This is less important than it has been in the past, but current versions of Zabbix still do not handle IPMI checks of hardware very well. We needed to write our own wrapper for IPMI checks rather than using the built in IPMI poller. Read full review Likelihood to Renew
It is free. It didn't cost anything to implement (other than my time and the cost incurred for it) and it is filling a badly needed gap in our IT infrastructure. Support is available if we have issues and can be done annually or paid for on a per incident basis as needed. Expansion, updates, and all other future lifecycle activities are likewise free of cost, so as long as someone is able to implement/maintain the software (and the OSS project is maintained) then I imagine the company will never leave it.

If you go deeper than the dashboards, the user friendliness goes away quickly

Community support does not give simple straightforward answers; simply search up Graylog Issues and look at some of the responses on the forums. The documentation is your only hope if you are on the free version, as you can NOT purchase only support. The few times I have worked with Graylog Enterprise support they were great though.

The setup is the most time-consuming portion of using zabbix. It takes a lot of effort to shape it into a usable format and even then it can get very messy. It's not exactly intuitive and as mentioned the UI seems a bit antiquated. If I was to roll out a monitoring solution from scratch, I'd probably look for alternatives which are easier to use and maintain.

We are a mainly Windows environment, so it would be useful if we could have used Active Directory to deploy agents. As of version 4.2, Zabbix has announced a new agent MSI file to allow exactly that. Unfortunately, we didn't have that option. Also, for Linux and MAC deployments, there is no simple way to deploy that. Using remote scripts you may be able to create something, but most places will opt for either SNMP (agentless) or manual installation of agents to add to Zabbix. A way of deploying agents via discovery would go a long way to helping in the adoption of the tool.

In terms of log aggregation, the free product fully stacks up with the competitors listed. Full control over the data ingests for flexible configuration. Graylog even better on that front than
because you cannot configure the variable mapping. We haven't used the threat exchange stuff or correlation. But with regex searches, we have created function dashboards that show threat theater pictures of our network based on logs from our firewall.

We're using the Solarwinds suite as our global monitoring standard, but it is very complex and its licensing model makes it difficult to monitor a wide range of technologies. So, we're using Zabbix as a complement on our monitoring process. Zabbix is a way more flexible and has free integrations to a wide range of technologies. It is also more 'user friendly' and easy to manage.
Read full review Return on Investment Graylog is just less expensive than some other options which meant it fit into our budget otherwise we might not be able to justify a higher cost. Being able to track issues that we normally couldn't track using other tools is a bonus to help us know of any issues we have and can fix before an outage or failure that could potentially cost money. We have had to spend more time than I would like to understand and customize Graylog which has taken time away from other tasks and projects. Read full review Zabbix simply makes it easier to identify, and subsequently resolve problems quickly Zabbix gives one web page to look at to see a list of all on-going issue in a single place Zabbix can automate response to alerts. For example, Zabbix allows you the customization to take a monitored server out of production rotation if it is identified as unhealthy Read full review ScreenShots
