3 open source distributed tracing tools

Distributed tracing systems enable users to track a request through a software system that is distributed across multiple applications, services, and databases as well as intermediaries like proxies. This allows for a deeper understanding of what is happening within the software system. These systems produce graphical representations that show how much time the request took on each step and list each known step. A user reviewing this content can determine where the system is experiencing latencies or blockages. Instead of testing the system like a binary search tree when requests start failing, operators and developers can see exactly where the issues begin. This can also reveal where performance changes might be occurring from deployment to deployment. It’s always better to catch regressions automatically by alerting to the anomalous behavior than to have your customers tell you.

• Using Red Hat Identity Management as a Domain Controller for systems in a DMZ

  The IdM server in the DMZ will play the role of the domain controller for Linux systems. To solve the problem of proxying Kerberos traffic make sure that the kdcproxy component is enabled on the IdM server that is inside the firewall. See corresponding documentation for more details. Linux systems in the DMZ will be connected to the IdM server by using ipa-client-install or realmd. The SSSD component will need to be configured on the clients. After the installation and enrollment the client systems would need to be reconfigured to start leveraging kdcproxy rather than a standard Kerberos protocol. For more details on how to achieve this see Configuring a Kerberos Client section in the System-Level Authentication Guide.
