The Business Process module is one of the most useful modules in NetEye, but it’s often underestimated. A Business Process offers a way to model relations between monitored objects by NetEye (host and services), allowing you to model applications or infrastructures. They also allow you to drill down into the details, from high-level services to…
Read More(Or, Who’s Monitoring the Monitor?) Everyone uses a monitoring system to understand what’s going on in their own environment and how it performs, but what about the monitoring system itself? The monitoring system also has its own tasks to perform, and obviously its own needs. Therefore even NetEye itself, while performing its duties, can be…
Read MoreBy using DMVmonitor to analyze query metrics on an MS SQL server instance, I was able to identify a missing index in the SQL server as the root cause of why an application was starting up quite slowly. In this specific case I was working in a production environment using Microsoft’s Dynamics AX 2012 R3…
Read MoreDo you need a customizable dashboard to better track problems detected by NetEye? Here’s one: WARNING This dashboard does not take into account the user’s role and related permissions and it is intended for use by an administrator on an on-premise non multi-tenant installation of NetEye. USE CASE The standard Problems display (divided into two…
Read MoreWhenever a new monitoring project gets underway, a consultant discusses with the customer about almost any related topic: what needs to be monitored, how to monitor it, when to implement it, how to represent performance data, etc. Based on customer needs and desires, any sort of implementation strategy can be planned, but almost all of…
Read MoreIn the world of IT monitoring, we often deal with metrics that are cumulative, or where we cannot control or modify the definition of a metric. Examples include the various Windows performance monitoring metrics for MS Dynamics AX 2013 R3 (AOS) server. These metrics are cumulative, but whenever the AOS services are restarted, or the…
Read MoreIn my previous blog post, I introduced our scenario: in a private cloud context, we want to deploy a dashboard for multiple clients created using Grafana, InfluxDB and Telegraf for SQL performance monitoring. We saw how to write a Grafana dashboard programmatically using Jsonnet and upload it to Grafana using the Grafana API. In this…
Read MoreSay we want to monitor the disk latency of SQL Servers or other Windows Performance Counters in a private cloud context, and plot the results for users of our performance management platform who likely work in different companies. InfluxDB, Telegraf and Grafana are the right tools to achieve this, and with the power of Flux,…
Read MoreA frequent request I get is how to view the availability of hosts and/or services within a Grafana dashboard. Here I demonstrate how to do this for host availability. To implement this, we first create a new table in our MariaDB on NetEye. I’ll call this table host_daily_sla and put it in the pre-existing reporting…
Read MoreWe fixed two security vulnerabilities related to the web interface.They were related to the cross-site request forgery attack and the clickjacking attack.Both are used to induce users to perform actions that they do not intend to perform by hiding the NetEye web interface under some eye-catching pages or with some malicious links sent for example…
Read More“A dashboard should tell a story or answer a question” “Dashboards should reduce cognitive load, not add to it“ Following the two best practices mentioned above I would like to consider the following use case: I am a NetEye customer with a single node implementation and I would like a dashboard that helps me to…
Read MoreI’ve been working with Grafana since 2017, when I started as a Frontend Developer here at Wuerth Phoenix.I typically take care of the customization of the Grafana User Interface, with the goal of reflecting the NetEye look and feel inside Grafana, aka the ITOA module. I’ve already written about a simple way to customize the…
Read MoreTo be able to make Elasticsearch Snapshots you need shared storage mounted on all Elasticsearch Data Nodes. There are various possible file systems you can use for this: GFS, NFS, CIFS and GlusterFS. What is GlusterFS GlusterFS is a scalable network file system suitable for data-intensive tasks such as cloud storage and media streaming. GlusterFS…
Read MoreTalking about IT security is now clearly synonymous with resilience! We are continuously and inevitably under attack… every organization must implement defensive principles and practices that avoid the worst damage and the least impact on its survival and development. From the data selection, to its collection and normalization, for its representation and analysis with techniques…
Read MoreInfluxDB is the database used in NetEye for saving performance data. It guarantees graphic visibility of the data (thanks to the Grafana frontend) and it is very important that the data stored is useful. I’ll give you an example of how simple it can be to produce obsolete data in Influx: Suppose I create a…
