I've been trying to use the db.ping() procedure listed here as part of a health-check script to monitor my Neo4j 4.0.0 instance.
The documentation says
"The procedure is available in all databases and always returns true."
However, when I try to use it when connected to a healthy database (
CALL db.ping()), I get this error:
There is no procedure with the name
db.pingregistered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed.`
When I run a query to see all the available procedures, the list returned for the
db namespace doesn't have
ping, confirming that
db.ping() is truly not available.
[... "indexes", "labels", "prepareForReplanning", "propertyKeys", "relationshipTypes" ...]
db.ping() procedure is said to be available on all databases, how do I find it / load it / use it? I haven't been able to find guidance in the linked documentation or nearby pages.
