Description

There are new HDFS alerts that watch growth rates. Some (like RPC) have "minimum" values, meaning we ignore growth until we are past a certain value (like latency in seconds).

There are a few other alerts that I think also need minimums. Or maybe need higher warning thresholds. Or both...

======
NameNode Heap Usage (Daily) increase_nn_heap_usage_daily

I'm getting these WARNINGS with a Heap of < 100MB.

The variance for this alert is 25MB which is 30% of the 82MB average (16MB is the limit).

====

HDFS Storage Capacity Usage (Weekly) namenode_increase_in_storage_capacity_usage_weekly

I'm getting these WARNINGS when only using such a small amount of storage...

The variance for this alert is 21,328B which is 20% of the 107,758B average (10,776B is the limit)

Here is what is used...

Disk Usage (DFS Used) 	112.0 KB / 428.1 GB (0.00%)
Disk Usage (Non DFS Used) 	32.0 GB / 428.1 GB (7.47%)
