Lithium, a leading social software provider, uses OpenStack as its private datacenter to host over 400 communities and various infrastructure services. Monitoring OpenStack is critical for Lithium's service platform, with failure being unacceptable due to the large number of production communities and infrastructure services hosted on it. Lithium engineers use Datadog to monitor OpenStack around the clock, correlating key metrics such as instances running, available memory, VCPUs available, and metric deltas to spot issues at a glance. They also set up advanced alerts for mission-critical metrics and have flexibility in informing the right people through various communication channels. Lithium adopted Datadog to gain deeper insight into their OpenStack deployment, adjust internal workflows, and react quickly to problems with minimal customer impact, saving time, money, and reputation.
