+Monitoring (Graphite)

Can you also please add a small section to
compute_engine_scripts/buildbots/README talking about what is in the monitoring
directory.

Done.

+=====================
+
+[Graphite](https://graphite.readthedocs.org/en/latest/) is a monitoring tool
+for servers and services. We are using it to monitor the runtime performance
+and behavior of the SkFiddle.com and the new SkPerf services, and maybe other
+services in the future.
+
+This document describes the setup procedure for the Graphite server and the
+process for loading data into the server.
+
+Full Server Setup
+=================

The different constants below could change based on the values in vm_config.sh
and based on the zone we are in.
Maybe it makes sense to create vm_create_server.sh, vm_delete_server.sh and
vm_setup_server.sh scripts in this directory that use the constants in
vm_config.sh

You can then refer to those scripts here instead of hardcoding values.

Done.

+Create a GCE instance:
+
+    gcutil --project=google.com:skia-buildbots addinstance skia-monitoring-b \
+      --zone=us-central2-b --external_ip_address=108.170.220.59 \
+      --service_account=default \
+      --service_account_scopes="https://www.googleapis.com/auth/devstorage.full_control" \
+      --network=default --machine_type=n1-standard-1 --image=backports-debian-7-wheezy-v20140331 \
+      --persistent_boot_disk
+
+SSH into the instance:
+
+    gcutil --project=google.com:skia-buildbots ssh --ssh_user=default skia-monitoring-b
+
+
+Do once
+-------
+
+The following things only need to be done once
+
+1. sudo apt-get install git
+2. git clone https://skia.googlesource.com/buildbot
+3. cd ~/buildbot/compute_engine_scripts/monitoring
+4. ./graphite_setup.sh
+
+Do on update
+------------
+
+To update the service ssh into the server and run:
+
+1. cd ~/buildbot/compute_engine_scripts/monitoring
+2. git pull
+3. ./graphite_setup.sh
+
+
