Tanzu - How to monitor memory usage of CC application code

Products

• VMware Tanzu Platform - Cloud Foundry

Issue/Introduction

As per TAS 10.2 Release Notes, the memory footprint of Cloud Controller is calculated as follows -

Memory Footprint - Each process loads a full copy of the Cloud Controller application code into its own memory space and does not share memory with other workers.

How do we calculate how many MB/GB the CC application code will be?

Resolution

For the memory footprint, it's recommendation to check each individual enviroment when doing this estimation.

The metrics vitals.mem_bytes / cc_vitals_mem_bytes metrics is best suited for this calculation.

See: https://docs.cloudfoundry.org/running/all_metrics.html#cc

cc_vitals_mem_bytes

The RSS bytes (resident set size) or real memory of the Cloud Controller process. Emitted every 30 seconds per VM.

Alternatively check monit status if you are SSH'd in to the control VM.

Example:

cloud_controller/#####-######:/# sudo -i monit status

 Process 'cloud_controller_ng'
