Post: Cluster uptime

Cluster uptime

I am investigating VotlDB stats and was wondering if there is any concept of cluster up-time?
I have looked at and run all variations of @Statistics, @SystemInformation and @SystemCatalog.

I'm not sure if a cluster has any statistics, or is it a case that a cluster only comes into being once a database is created.
In which case should I be more concerned about database up-time?

So basically is there any way of telling how long a cluster/database is running since it was started?

A cluster only comes into existence once a database is created or recovered. We do not currently have a way to get uptime, but I've logged it as a feature request.

We implemented this feature in V4.2. It shows up in the SystemInformation system procedure:

$ sqlcmd
1> exec @SystemInformation overview;
