Vizceral Metrics Adapter

This project acts as the literal translation layer between the data presented from each foundation by app-metrics-nozzle so that it can be be transformed it into the data model expected by vizceral-app-metrics-ui

Configuration

Configuration is relatively straight forward using contsants and variables at the top of index.py

The Notice thresholds for information/warning/danger graph decorations can be modified by tweaking the following constants:

# Constants for warning checks
THRESHOLD_CPU_DANGER      = 75
THRESHOLD_CPU_CRIT        = 50
THRESHOLD_CPU_WARN        = 25

THRESHOLD_RPS_DANGER      = 1000
THRESHOLD_RPS_CRIT        = 500
THRESHOLD_RPS_WARN        = 100

# The next 2 sets of thresholds are expressed as % used
THRESHOLD_MEM_DANGER      = 90
THRESHOLD_MEM_CRIT        = 75
THRESHOLD_MEM_WARN        = 60

THRESHOLD_DISK_DANGER     = 90
THRESHOLD_DISK_CRIT       = 80
THRESHOLD_DISK_WARN       = 75

# Add a notice to the node if not in the state defined below
THRESHOLD_RUNNING_STATE   = "RUNNING"

The configuration for each foundation one wishes to visualize (or for each installation of app-metrics-nozzle) is set like so:

# First Foundation
pcf_one = {}
pcf_one["name"] = "pcf-secondary"
pcf_one["displayName"] = "Secondary PCF"
pcf_one["json_url"] = "https://app-metrics-nozzle.apps.your-pcf.com/api/apps"
pcf_one["exclude_orgs"] = []
pcf_one["only_orgs"] = ["second-foundation"]

# Second Foundation (which is really just the first, repeated with different filters)
pcf_two = {}
pcf_two["name"] = "pcf-primary"
pcf_two["displayName"] = "Primary PCF"
pcf_two["json_url"] = "https://app-metrics-nozzle.apps.your-pcf.com/api/apps"
pcf_two["exclude_orgs"] = ["system", "second-foundation"]
pcf_two["only_orgs"] = []

Note that exclude_orgs and only_orgs can be used to selectively include/exclude certain ORGs to reduce some of the "clutter" in the visualization.

Finally, ensure that every Foundation one defines has been packed into the array which will be iterated over to build the final data model:

# Pack the list of foundations to process into the hash "foundations"
foundations[pcf_one["name"]] = pcf_one
foundations[pcf_two["name"]] = pcf_two

#
# END Configuration
#

Once fully configured, push an instance to your PCF/CF and then ensure one has deployed vizceral-app-metrics-ui to sit infront of the adapter.
