3.4. General Guidelines
The Metrics Collector Mode, TTL Settings, Memory Settings, and disk space requirements for AMS are dependent on the number of nodes in the cluster. The following table lists specific recommendations and tuning guidelines for each.
| Cluster Environment | Host Count | Disk Space | Collector Mode | TTL | Memory Settings |
|---|---|---|---|---|---|
|
Single-Node Sandbox | 1 | 2GB | embedded | Reduce TTLs to 7 Days |
metrics_collector_heap_size=1024 hbase_regionserver_heapsize=512 hbase_master_heapsize=512 hbase_master_xmn_size=128 |
PoC | 1-5 |
5GB | embedded | Reduce TTLs to 30 Days |
