This issue happens in VMware Tanzu Application Service 2.13.20 and 2.13.21.
This issue happens in VMware Tanzu Application Service 2.13.20 and 2.13.21.
Environment
Product Version: 2.13
Resolution
Explanation:
With the release of TAS 3.X there has been a change in how the product handles the app log rate limitations. Operators can configure app log rate quotas for each org and space in a TAS for VMs v3.X deployment, as well as app log rate limits for individual apps so that noisy apps are no longer overwhelming Loggregator with app logs. The global log rate limit that measures app log rates in lines per second is deprecated in favor of per-app log rate limits that measure app log rates in bytes per second. As a result, the option to enable App log rate limit under App containers pane is now showing as “deprecated” in TAS 3.X versions.
However, the change has made its way to TAS 2.13.20 and 2.13.21 where in Apps Manager certain functionalities require to set the log rate limit field, for example, scale app. Please note that this feature was not available in versions prior to TAS 2.13.20 and there is no mention of this change in the release notes.
To get more details, please refer: Issue with log rate limits in TAS 2.13.20 & 2.13.21
Temporary-Fix:
Users can set manually scaling rules using the cf-cli, refer Scaling an app using Cloud Foundry CLI (cf scale) | Cloud Foundry Docs. Can also use the autoscaler cli plugin if autoscaling rules need to be updated, refer Using the App Autoscaler CLI.
Permanent-Fix:
A fix for the Apps Manager scale issue has been shift in 2.13.22.
