Software developers are often only concerned about the functionality of their applications. When these applications are deployed in production, scalability and performance issues surface and application developers then have to worry about performance. Many a times, such situations warrant a complete restructuring of the application code, causing significant impact to new rollouts and current users.
Simple Network Management Protocol (SNMP) is an Internet Standard protocol for collecting and organizing information about managed devices on IP networks and for modifying that information to change device behavior. SNMP exposes management data in the form of variables on the managed systems organized in a management information base (MIB), which describe the system status and configuration.
It’s no secret that Application Performance Monitoring (APM) is becoming a critical competency in today’s enterprise networks. After all, so many enterprises are moving to a cloud-based model that leverages tiers of service, which brings unforeseen complexity into the task of keeping things running smoothly.
As microservices gain in popularity, containers have become a hot topic for developers. But how do they differ from virtual machines? Will containers replace virtual machines? And when should you choose containers over virtual machines? When it comes to defining virtual machines, the name says it all – machines (servers or desktops) that have been virtualized.
So, why would you deliberately try to break your services? Chaos engineering does just that – deliberately terminating instances in your production environment. Online video streaming service Netflix was one of the first organizations to popularize the concept with their Chaos Monkey engine.
Most of you know that one of the most important user experience metrics in a Citrix environment is the logon time. A 2018 survey by eG Innovations and DABCC found out that Citrix logon time was the number one problem for administrators: 59% of respondents rated logon time as their biggest problem. There are many best practices to improve Citrix logon times. Slowness during the logon processing can, of course, increase logon times. Issues with group policies or slow profile loading is often a cause.
While tuning the performance of your application at the code level or sizing the JVM appropriately are important for enhancing performance, it is equally important to look at how to tune accesses to the backend database. After all, response time for a web request is dependent on the processing time in the Java application tier as well as the query processing time in the database tier.
