Hello All, I have been blogging about real-time IT and various dimensions of Application Performance Management (APM) for the past few weeks . I am now starting a new three-series blog that will be along the lines to what the eBook, which we released in November last year, talks about. We are also doing a Webinar on 25 th January, 2012 where, along with me, Sridhar Iyengar, VP, Product Management, ManageEngine, will be explaining the first steps to real-time IT with a few business scenarios.

EventLog Analyzer – a perfect log management tool
Until recent years, enterprise IT infrastructure comprised of a few basic network devices. IT managers used simple tools to collect generated logs and analyzed them manually to generate log reports. IT heads and administrators viewed log management more as a means to monitor devices than as an aid for securing the network. With ever-increasing security threats over the recent years, log management has evolved as an integral part of organization
Have you hugged your IT person today?

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.

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
