Intro – Building IT Services on Verifiable Insight

PT Weefer Indonesia is a Jakarta-based IT system integrator that provides and operates mission-critical cloud solutions for businesses throughout Indonesia, spanning HR platforms, ERP, CRM, and managed cloud services. As customer reliance expanded to organizations with nearly 1,000 employees, the Weefer team recognized that traditional troubleshooting—largely dependent on manual logs and assumptions—was no longer sufficient. To establish a modern, data-driven IT operations model and protect Service Level Agreements, Weefer adopted WhaTap Monitoring to secure clear, end-to-end observability across live environments.

Challenges – From Guesswork to Root-Cause Uncertainty

While operating cloud-based HR services, performance slowdowns frequently triggered customer complaints, particularly around daily attendance processing. Because the platforms were already in active use, the Weefer engineers struggled to determine whether issues originated from APIs, database queries, bandwidth saturation, or hosting infrastructure.

Without integrated visibility, investigations required manual inspection and trial-and-error fixes, extending resolution times and increasing the risk of SLA breaches. The absence of numeric evidence meant the team could only infer the true source of problems, making proactive optimization virtually impossible.

Solution – Integrated Visibility With WhaTap Hit Map

WhaTap delivered two decisive capabilities for Weefer.

Infrastructure utilization monitoring provided real-time insight into CPU, memory, and network consumption across the cloud resources under management.

Application-level observability revealed performance issues that do not surface during development but emerge only through actual user interactions. The Hit Map feature, in particular, visualized periods of underperformance and immediately correlated them with specific APIs and system queries.

Armed with this integrated view, the Weefer engineers can now pinpoint bottlenecks precisely and optimize APIs and database queries without disrupting live services, establishing a single source of truth for incident response.

Outcomes – Proven Performance & Operational Savings

The impact of WhaTap was immediate.

• SLA Compliance Increased by More Than 50% during 2024–2025, supported by faster detection and sharply reduced Mean Time to Resolution for attendance and bandwidth-related incidents.
• API Bottleneck Identification Accuracy Reached 100%, eliminating assumption-based diagnosis and enabling prompt customer feedback.
• Server Over-Provisioning Reduced by 30%, generating double-digit cloud cost savings across hosted projects.
• Customer Complaint Volume Fell by 40%, strengthening trust in Weefer’s HR, ERP, and CRM services.

Robert Liandro concluded, “WhaTap has enabled our team to operate with verifiable insight rather than guesswork. We aim to grow alongside the WhaTap team and continue delivering the highest quality services to businesses in Indonesia.”
