Optimizing Call Logging for a Telco

The Client is a leading wireless network operator with the largest 5G network.

Business Problem

The client's enterprise systems comprised multiple upstream and downstream systems that participated in fulfillment of a business function. There were a few issues with effective triaging across cross-functional microservices teams

Lack of standardization in logs and ineffective usage of log analytics tools like Splunk, led to significant time spent by the Client’s teams in analysing the issue before it was assigned to the right team. Many times, this delay used to impact critical business activities
No unified way of tracking and visualization of request from source service to the leaf node in the hierarchy (L0 to L5)
No standard procedure of logging entries and error reporting by various cross functional teams.
No visibility on significant latency issues in microservices.

The Solutions

Our team did a thorough analysis of the logging system and implemented the following changes:

Standardized logging across all the product and technology platforms
Built effective triaging dashboards in Splunk using inbuilt indexing and analytics features, captured through a logging framework
Identified high latency downstream API’s and resolved latency issues by tracking contribution of each service to its hierarchy
Built dynamic sequence of events - reducing the need to maintain sequence diagrams - for system design and architectural improvements

Value Delivered

Drill down capability to track all the logs. The cross functional and geo-based teams found it very effective. They were able to identify the team responsible for resolving the issues
The turnaround time for issue resolution was reduced from multiple days to minutes
The dynamic performance metrics helped identify and resolve bottlenecks with no effort spent in identifying it.
