Nagios Plugins Plugins allow you to monitor hosts, devices, services, protocols, and applications with Nagios. Recently I was asked the following questions via email and thought it would make a great post to explain the differences between deploying Nagios Log Server or just the Elasticsearch, Logstash, Kibana Stack (ELK). In the company I currently work with, we were thinking about deploying ElasticSearch and Logstash along with Kibana, in order to further facilitate log processing and visualization.
What would the added value be if we went for Nagios Log Server instead of ElasticSearch, Logstash and Kibana?
Is there any downside in choosing to install ElasticSearch, Logstash and Kibana on our own instead of installing Nagios Log Server? On the surface this is a really straight forward question, and was also asked right away in the Log Monitoring and Log Management with Nagios presentation I gave at the Nagios World Conference.  Nagios Log Server does in fact use the ELK stack, and we are surely glad we chose the stack we did because of the outstanding performance, reliability, redundancy and expandability that it allows Log Server to take advantage of to build this spectacular product.
While both options allow a platform that will give the ability to index and analyze logs from various systems such as syslog, Windows Event Log, text based logs and many many more, Nagios Log Server was designed to be a full featured Log Management product, taking into account the needs of enterprise customers that require important items such as security and role based authentication.
Authenticated UI and API – Believe it or not, the ELK stack does not come with any semblance of authentication or authorization, which means anyone that can access the ELK system on the network can not only read, but Delete or Modify your sensitive log data. Per user savable Queries – Queries can be saved separate from dashboards, and you can apply different queries to be viewed in different dashboards.
Global Dashboards and Queries – Both queries and dashboards can be saved as Global by administrators so other individuals can use them.
GUI based Cluster Management – At a glance view and management of the Log Server cluster status right through the GUI.


GUI based Instance Management – Granular view of every member of the cluster, including about 60 metrics such as, disk utilization, memory usage, system load, and so much more. GUI based Index Management – Detailed view (another 25 metrics per index) and actions on every index in the cluster, such as document count, size, and ability to open close, and delete indexes. Currently Requires CentOS or RHEL – Currently Nagios Log Server is only supported on CentOS or RHEL operating systems, however we are working to get distributions on other operating systems available, and it can be run in a VM on virtually any OS.
We welcome additional questions in the comments below.  Feel free to take Nagios Log Server for a fully functional 90 day free trial. The JSON CGIs, from the JSON branch of core, have been officially released with Nagios Core 4.0.7!

It is a very cool dashlet, that in my opinion, doesn’t get the attention it deserves. Then you can go to the dashboard, where you added that dashlet and view status info for your service.
