Monitoring PAS

Warning: Pivotal Cloud Foundry (PCF) v2.5 is no longer supported because it has reached the End of General Support (EOGS) phase as defined by the Support Lifecycle Policy. To stay up to date with the latest software and security updates, upgrade to a supported version.

This guide describes how Pivotal Cloud Foundry (PCF) operators can monitor their Pivotal Application Service (PAS) deployments. For information about monitoring Pivotal Container Service (PKS) deployments, see Logging and Monitoring 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 v2.4 to v2.5

This table highlights new and changed KPIs and scaling indicators in PAS v2.5.

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 backend. N/A
Modified CF Syslog Drain Bindings Count In PAS v2.5, the CF Syslog Drain Bindings Count scaling indicator uses the following derived metric: cf-syslog-drain.drain_adapter.drain_bindings / number of Syslog Adapters CF Syslog Drain Bindings Count
New Log Cache Caching Duration The Log Cache Caching Duration scaling indicator indicates the age in milliseconds of the oldest data point stored in Log Cache. This metric is useful for determining when to scale the VMs on which Log Cache runs. Log Cache Caching Duration
