Technical Challenge

  • Stability issues, improper application programs create memory leaks result in unnecessary logs filling system disk space.
  • The total monitoring system was in disarray since it is a legacy monitoring tool it relied more on conventional scripts.
  • The solution must be an additional architecture instead of disturbing existing systems.

SrinSoft Solution

  • Our consultants have created a set of rules, procedures, and practices to bring the ESB server architecture to a stable state. The following breakdown structures are used to mitigate the challenges and the uninterrupted system.

Transition support to offshore

  • Existing monitoring was maintained as on-call support whereas resources will be operating from offshore.
  • SrinSoft identified the lag in monitoring and replaced the existing system with 24*7*365 support structure.
  • Support plan was transitioned to the offshore facility to a team contains highly specialized and RedHat certified Linux and JBoss administrators. Offshore facility centre located in Chennai, India

Reengineering

  • SrinSoft Consultants preferred to utilize the existing monitoring tool in an effective way.
  • Out of two various monitoring tool (JON and Fuse HQ) our consultant preferred FuseHQ for dynamic monitoring of the client ESB architecture
  • Monitoring scripts were slowly retired from the day to day usage and all metrics were moved to FuseHQ

24x7 Monitoring

  • All applications logs were backed up with automated scripts to avoid disk space issues

Debugging renewed

  • Application debugging identified serious memory leaks and it was assigned to developers for bug fixing.

  • Present, Visualize, Analyse

Tools
