Who is using your network and how? What kind of traffic does your company generate? Where does slow network performance come from? ntop has the answers. ntop is a network traffic probe that monitors network usage. This solution provides an intuitive, encrypted web user interface for the exploration of both real-time and historical traffic information. In our…
Read MoreSo you have MSSQL databases and you’d like to keep an eye on the performance of your DB. Using NetEye this is quite easy. The tools you need are already available on your NetEye server: InfluxDB, the Telegraf agent, and Grafana for visualizing your Dashboards. The SQL Server Input Plugin provides metrics for your SQL…
Read MoreRemote Desktop Services 2016: The AppContainer Windows Server 2016 introduced the “AppContainer”, which is created when users connect to the server for the first time. Due to a registry leak, the Windows Server generates registry bloat for firewall rules. This registry bloat can be found in the following registry keys: HKLM\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\FirewallRules HKLM\System\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy\RestrictedServices\Configurable\System Over time, this…
Read MoreHistorically, NetEye Clusters were configured with DRBD as Master/Slave resources. This led to the following rather cumbersome resource configuration for an N-node cluster: $SERVICE_drbd_master ( x 1 ) $SERVICE_drbd_master_clone ( x N ) $SERVICE_drbd_fs $SERVICE_virt_ip $SERVICE Note: $SERVICE serves as a placeholder for any Cluster Service running in NetEye 4. At least ten constraints were…
Read MoreFrom this November 5th to 8th, more than 250 system engineers, developers, network engineers and IT managers met in Nuremberg, Germany to discuss the latest approaches to monitoring and observability. The four-day event comprised 3 tracks of expert presentations on November 6th and 7th, technical workshops on the 5th, and a full-day hackathon directly following…
Read MoreIn my last user guide blog I showed you how to create your own menu item, create a space on the file system, write a sample page, and store an image for that page, all in a way that will survive future updates. This time I want to show you how to use your custom…
Read MoreOCS Inventory is part of our Asset Management module integrated into NetEye. Open Computer and Software Inventory Next Generation (OCS Inventory NG) is free software that enables users to inventory IT assets. OCS-NG collects information about the hardware and software of networked machines from the machines themselves running the OCS client program (“OCS Inventory Agent”)….
Read MoreAs already mentioned in my other blog posts, NetEye 4 is based on Icinga Web 2, a powerful PHP framework. During the development of some of our custom NetEye modules for Icinga Web 2, we needed to include some new, custom jQuery plugins to create a neat new effect in the GUI. For example, with…
Read MoreInfrastructures get reorganized, organizations grow and naming conventions change. Icinga2 nodes can reliably trust each other by following the guidelines for certificate generation and building a dedicated certificate chain. Certificates rely on hostnames and DNS, which aren’t usually subject to changes, but it does happen sometimes. What then? First of all, all certificates in NetEye’s…
Read MoreRemote Desktop Services (RDS) Performance In a complex distributed RDS environment, it’s difficult to measure RDS performance: the end user typically notices responsiveness in a different way compared to measuring a single Windows Performance Counter! Overall performance tends to degrade over time: and frequent maintenance is required to keep an RDS Farm efficient. Of course,…
Read MoreThe hackathon with the most panoramic view this week took place on the “Plan de Corones” in South Tyrol. The over-2000-meter a.s.l. event venue in the Puster Valley offered exciting development challenges, a breathtaking view within the heart of the Dolomites, and many chances to express creativity even beyond lines of code. Würth Phoenix contributed…
Read MoreIt all started with a pretty simple purpose: “The initial idea behind ntop was to create a simple tool to enable network visibility without having to deal with complicated network protocols,“ says ntop founder Luca Deri. What followed were 20 years of the highest quality development, motivation and passion, bringing ntop to what it is…
Read MoreTelegraf is a plugin-driven agent for collecting metrics from various sources (based on the configured input plugins), preprocessing and aggregating them (based on configured processor and aggregator plugins), and forwarding them to the desired destinations (depending on the configured output plugins). Telegraf is used throughout NetEye to collect performance data, forward them to InfluxDB where…
Read MoreWith this article I will talk about a recent customer project on End User Experience within a distributed environment. When we use the word “distributed”, we usually think about sites distributed across multiple cities or continents. This project focused on monitoring the quality that IT users experience between the ground floor and the 2nd floor…
Read MoreA Little History The Microsoft Remote Desktop Services (RDS) architecture is widely used to publish centralized Desktop and Windows Applications to users from remote sites. With RDS, only the software user interfaces are transferred to the client system. All input from the client system is transmitted to the server, where software execution takes place. RDS…
