Going beyond plain virtualization monitoring
Virtualization technology has transformed the way business works with IT. However, rapid virtualization and the co-existence of virtual environments with physical and cloud entities have introduced many new complexities to businesses from an IT management point of view. While conventional monitoring tools can provide performance monitoring to an extent, they mostly lack the necessary operational intelligence required to track today’s complex virtualized infrastructures.
Data representation and Unified Dashboards
This is in continuation of Part 1 discussed in this blog. In this section, I shall take you through the various features of Dashboards as offered in IT360 and how to use them. One major need that you come across in managing the day to day operations of your IT [from IT Infrastructure Management tools] is to create custom dashboards specific to the following roles in your IT Department: Network Dashboards and Traffic Dashboards for your Network Administrators System Dashboards for your System Administrators Applications Dashboards for your Application Administrators Server Dashboards for your Server Administrators Dashboards for IT Managers, and CXOs And, the most important aspect of IT360 dashboards are its widgets and the possibilities / choices that it offers.
Role-based access control for device configurations, key for ensuring network security
The configurations of network devices are crucial from the standpoint of network security. The configurations contain sensitive information such as access credentials, SNMP settings, ACLs and others
High Java CPU due to String Concatenation – String + Vs StringBuffer or StringBuilder
Many of you might know, the String concat(+) is costly operation compare to StringBuffer or StringBuilder append() method. But you might not know the actual performance difference. Let me show you the performance difference with a simple test program, package test; public class StrVsBuffVsBuild { public static void main(String[] args) { int count=200000; System.out.println(“Number of Strings concat Operation is ‘”+count+”‘”); long st = System.currentTimeMillis(); String str = “”; for (int i = 0; i < count; i++) { str += "MyString"; } System.out.println("Time taken for String concat (+) Operation is '"+(System.currentTimeMillis()-st)+"' Millis"); st = System.currentTimeMillis(); StringBuffer sb = new StringBuffer(); for (int i = 0; i < count; i++) { sb.append("MyString"); } System.out.println("Time taken for StringBuffer.append() Operation is '"+(System.currentTimeMillis()-st)+"' Millis"); st = System.currentTimeMillis(); StringBuilder sbr = new StringBuilder(); for (int i = 0; i < count; i++) { sbr.append("MyString"); } System.out.println("Time taken for StringBuilder.append() Operation is '"+(System.currentTimeMillis()-st)+"' Millis"); } } Following are the output of the above test program, Number of Strings concat Operation is '200000' Time taken for String concat (+) Operation is '373933' Millis Time taken for StringBuffer.append() Operation is '19' Millis Time taken for StringBuilder.append() Operation is '5' Millis The String concat (+) took 6.2 Minutes , however others took only 19 / 5 milliseconds
