The performance graphs present in NetEye are very useful for getting an immediate idea of the trend related to a service check, but they’re still limited to the metric being viewed. Also, the “Show all graphs” option available from the Actions menu of each monitored Host can have different usage limits due to the presence…
Read MoreBy default all metrics in InfluxDB are stored forever, but for certain metrics we need to store them for a much shorter time span. One example is when we’re receiving very large amounts of raw data, when we’re much more interested in derived characteristics of that raw data. In this blog we’ll discuss how to…
Read MoreA customer with a NetEye installation to which I had added the nTop module asked me if I could integrate nTop’s Grafana Dashboards, so they could view them by consulting NetEye’s ITOA Menu. The installation and configuration of nTop for this client, a task I had already conducted some time ago, was a matter of…
Read MoreITOA ITOA is the NetEye component which represents time series data using the Grafana graphics engine. Data is usually collected by Telegraf agents and stored into an InfluxDB specialized non-relational database. Flux In order to manipulate the time series data, Grafana usually adopted a relational language: InfluxQL. The relational approach has had a number of…
Read MoreRecently a customer told me he would like to monitor and graph the values that his Fortigate Firewall was generating for his configured SLA Trackers. What are these SLA Trackers? I informed myself and found the following in a Fortigate Cookbook. Fortigate Performance SLA ─ Link Monitoring Performance SLA link monitoring measures the health of…
Read MoreThe 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…
