Scenario:

Put some objects to node with writecache enabled
Wait until writecache flushes all objects
Also frostfs_node_writecache_actual_objects_total metric will be negative

service@aanikeev-node2:~$ curl -s localhost:6672 | grep frostfs_node_writecache_actual_objects_total
# HELP frostfs_node_writecache_actual_objects_total Actual objects count in writecache
# TYPE frostfs_node_writecache_actual_objects_total gauge
