Most of the companies in the corporate world have more than a monitoring system, at least 3 in my experience: sysadmins have at least one, network guys another one and one for legacy platforms (mainframes, as400 and so on). Plus, in the last years with the rise of Kubernetes, most corporates have at least one cluster with Prometheus monitoring it. Always, base on my experience, Prometheus is very popular, but the adoption is not so wide due to its `oss nature`: CTOs want someone to blame when things go wrong.
