Monitoring PAS

These topics describe how Pivotal Cloud Foundry (PCF) operators can monitor their Pivotal Application Service (PAS) deployments. For information about monitoring Enterprise Pivotal Container Service (Enterprise PKS) deployments, see Logging and Monitoring Enterprise PKS.

For more information about logging and metrics in PCF, see Overview of Logging and Metrics.


This guide includes the following topics:

  • Key Performance Indicators: A list of Key Performance Indicators (KPIs) that operators may want to monitor with their PAS deployment to help ensure it is in a good operational state.

  • Key Capacity Scaling Indicators: A list of capacity scaling indicators that operators may want to monitor to determine when they need to scale their PAS deployments.

  • Selecting and Configuring a Monitoring System: Guidance for setting up PAS with monitoring platforms to continuously monitor component metrics and trigger health alerts.

KPI and Scaling Changes from PAS v2.5 to v2.6.

This table highlights new and changed KPIs and scaling indicators in PAS v2.6.

Status Metric Description Reference
Removed Number of Route Registration Messages Sent and Received These gorouter.registry_message.route-emitter and route_emitter.HTTPRouteNATSMessagesEmittedmetrics are no longer an accurate representation of routing health. In PAS v2.4 and later, Gorouter skips the TTL for routes that are registered with TLS. This means the routes never expire or get pruned, other than in an attempt to connect to an invalid back end. N/A
Modified Doppler Egress Dropped Messages Within PAS, logs and metrics enter Loggregator for transport and then egress through Doppler. Doppler drops messages when consumers of the RLP, such as monitoring tool nozzles, ingest the exiting stream of logs and metrics too slowly.

Note: The doppler.dropped metric includes both ingress and egress directions, but egress is a newly added distinction. To differentiate between ingress and egress, see the direction tag on the metric.
