 # Heap Watch
 
-Tools for checking if algod has memory leaks.
+Collect RAM, bandwidth, and other stats over the course of a test cluster run.
 
-Run a local private network of three nodes and two pingpongs.
+Produce reports and plots from data.
 
-Periodically sample pprof memory profiles.
+## Scripts
 
-Watch memory usage from `ps` and write to a CSV file for each algod.
+* heapWatch.py
+  * collect data from algod
+  * heap profiling, /metrics, cpu profiling, block headers, goroutine profile
+  * capture from local algod by data dir or cluster from terraform-inventory.host
+  * convert profiles to svg or other reports
 
-# Usage
+* block_history.py
+  * Capture block headers every round from a running `algod`
+
+* block_history_relays.py
+  * Capture block headers every round from one or more running `algod`
+  * Talk to a set of relays found in a terraform-inventory.host file.
+
+* block_history_plot.py
+  * Plot the output of test/heapwatch/{block_history.py,block_history_relays.py}
+
+* client_ram_report.py
+  * Process heap profiles (*.heap) collected from heapWatch.py
+  * Create a report on `algod` RAM usage
+
+* plot_crr_csv.py
+  * Plot the output of test/heapwatch/client_ram_report.py --csv
+
+* metrics_delta.py
+  * Process /metrics data captured by heapWatch.py
+  * Generate text report on bandwidth in and out of relays/PN/NPN
+  * optionally plot txn pool fullness
+
+* start.sh stop.sh
+  * Run a local private network of three nodes and two pingpongs.
+  * Periodically sample pprof memory profiles.
+  * Watch memory usage from `ps` and write to a CSV file for each algod.
+
+* bwstart.sh stop.sh
+  * Run a local private network of 3 relays and 8 leafs
+  * Run 40 TPS of payment txns through it.
+  * Record metrics for bandwidth analysis.
+
+* runNodeHost.py nodeHostTarget.py
+  * run new ec2 host with npn and pn algod on it pointed at one relay (no DNS needed)
