Case study
Legacy Retail Chain Gains End-to-End Observability
How SquareShift bridged legacy SNMP, storage, and virtualization systems into Elastic for a 120-year-old US department store chain's e-commerce platform.
One of the oldest department store chains in the United States, in operation for more than 120 years and generating close to 50 million e-commerce visits a month.
Its catalog spans thousands of SKUs across a large legacy digital footprint.
Monthly e-commerce visits kept under unified observability. Legacy SNMP, storage, and virtualization brought into one Elastic pipeline. Purpose-built parsers for previously unsupported protocols.

The challenge
The client — one of the oldest department store chains in the US, running an e-commerce platform used nearly 50 million times a month — had already deployed Elasticsearch for centralized log management. But the system still couldn’t see into large parts of its legacy infrastructure, because Elastic’s out-of-the-box integrations didn’t cover it.
Outdated protocols like SNMP, plus storage and virtualization platforms that predated the client’s Elastic rollout, produced formats the stack couldn’t natively ingest — leaving real blind spots in the observability picture.
What we delivered
SquareShift built custom integrations and parsers to close those gaps, normalizing legacy SNMP traps into the Elastic Common Schema (ECS) so old and new data could sit side by side. A centralized Logstash fleet now manages ingestion pipelines across the full mix of sources.
The team added support for Pure Storage and VMware vCenter — two systems with no native Elastic integration — bringing them into the same observability layer as everything else.
The payoff
The retailer now has end-to-end observability across its full stack, legacy and modern alike, covering close to 50 million monthly e-commerce visits with one correlated view instead of blind spots around older infrastructure.
Deep protocol expertise, not a platform swap, closed the gap — the client kept its existing Elastic investment and extended it, rather than replacing tooling to get full-stack coverage.
The hard part of legacy observability is never the dashboard — it's writing parsers for protocols vendors stopped documenting years ago.
