Middleware is where applications meet infrastructure. Here our consultants write about WebLogic, JBoss EAP, WildFly and Tomcat in real production environments: installing and clustering them, patching, deploying applications and finding out why something stopped working.
So far, for Zabbix monitoring, I only covered Linux based servers. We can put aside MS-SQL which was monitored via ODBC, thus without any Zabbix agent involved. In this blog post, I will explain you how I was able to monitor a Document Manage System (DMS) like M-Files which is running on Windows. By the way, Vincent did a great…
In a previous blog post, I explained how to monitor Apache Tomcat with Prometheus with help of JMX exporter. It is not always desirable to use JMX as it requires: Fortunately, it is possible to instrument a JVM directly with an additional javaagent argument. Java Agent Once we downloaded the java exporter from github repo, we simply need to add…
In this blog post, I will show you how to gather metrics from a OpenTelemetry interface from a Zabbix server and how to display Zabbix data in Grafana. Why Should I do that? First, you might wonder why should you even do that? Dashboards capabilities of Zabbix are nice and evolving but is not as complete and customizable as Grafana…
When working with any ECM solution, you will have to manage a rendition software. This is used to transform the native documents from most formats (docx, pptx, xlsx, txt, jpeg, png, svg, etc.) into another format (pdf, png, etc.). The rendition can then be used for a multitude of use-cases: thumbnails, previsualization purposes online/in a browser, for security/conformity to certain…
A typical web application architecture with a load balancer, two application servers and a database looks like this: If you run a JMeter, or any load test tool, from one unique server or workstation, the load balancer will most likely route all traffic to only one of the application servers. Why is that? Mainly because the load balancer uses the…
Writing an Apache JMeter scenario is not an easy task. Debugging a scenario is even harder. One might think that JMeter is simply recording some browser actions and that’s it, and you are good to go for a load test. This could be valid if the scenario does not require any login. When it does require login, there will be…
There are several Electronic Content Management tools (ECM) on the market that are very powerful in their functionalities but are not always easy to configure or maintain, particularly if the size of your company does not allow for a large IT department. However, a good document management in a company is a necessity to: – Avoid administrative pitfalls – Optimize…
In this blog post, we will quickly see what is required to monitor a Microsoft SQL Server with Zabbix. Agent Setup Agent setup is not required by MSSQL by ODBC template; thus this step can be skipped. Setup Monitoring Account The best practice is to create an account in the database dedicated to monitoring which will have limited permissions (view,…
The aim of that blog is to look into Oracle REST Data Services (ORDS) 23.x error raised when setting up for APEX 23.1. This is following some experience at a customer who wanted to move to latest version of ORDS with APEX 23.1, in late 2023, and ran into an issue. If you have encountered similar error as below, when…
Introduction The event took place in a very pleasant street, the Königsallee, also known as the Kö, is a shopping street in Düsseldorf and considered to be the most beautiful avenue in Düsseldorf. Whaou !! The Hyland Summit 2023 in Düsseldorf is the right place to learn and seek innovative ways to manage, secure, and harness the power of the…
In this blog post, I will share a few obstacles I have encountered while trying to monitor a complete Alfresco setup with all these components. As an overview, here are the templates I will use: Until now, I only did simple monitoring: One component, one host. As a matter a fact, having multiple Java Virtual Machine (JVM) on same host…
Until recently, I did not notice that Zabbix templates can also include Hosts prototypes under (Low Level) Discovery Rules. I wondered why, so I decided to look at pre-existing templates to check what is the aim for it. I chose to focus on “AWS on HTTP” template. “AWS on HTTP” Template The documentation is clear enough and straight forward for…
