A Christmas miracle
And then, just when things seemed easy … Christmas happened.
On the day that online delivery slots were to be released for December, more than 20,000 people logged into Tesco’s online waiting room, ready to snag a slot. Demand was so fervent that Tesco became a topic of national conversation, trending on Twitter the entire day. “The pressure on our systems was unlike anything we’ve seen, and having Splunk to provide visibility into these systems was critical to to fulfilling our customers’ needs,” says Olive.
Tesco engineering and operations teams used Splunk to monitor everything from infrastructure health to critical business transactions to the virtual waiting room. “During this Christmas surge, Splunk helped us improve our monitoring, observability and entire software development environment,” says Davood Torabzadeh, Splunk product manager at Tesco. “Because it was easy to set up Splunk and launch monitoring dashboards, we could repeat that practice over everything.”
