Troubleshooting On-Demand Instances
Page last updated:
This topic provides techniques app developers can use to begin troubleshooting on-demand instances.
You might experience the following during upgrades or in a leader-follower topology.
MySQL for PCF service instances can become temporarily inaccessible during upgrades and VM or network failures. For more information, see Service Interruptions.
If you have a leader-follower topology and your apps can no longer write to the database, the leader VM might be read-only. Contact your operator to check if the leader VM is read-only. For more information about troubleshooting this problem, see Both Leader and Follower Instances Are Read-Only.
If you can no longer read to the database as well, your persistent disk might be full. For more information about troubleshooting inoperable apps, see Apps are Inoperable.
If your apps become inoperable, your persistent disk might be full. In this state, read, write, and Cloud Foundry Command-Line Interface (cf CLI) opertations do not work.
Contact your operator to check if your persistent disk is full. For more information about troubleshooting this problem, see Persistent Disk is Full.
You might see an error when using the Cloud Foundry Command-Line Interface (cf CLI) to perform basic operations on a MySQL for PCF service instance:
Failed operations (create, update, bind, unbind, delete) result in an error message.
You can retrieve the error message later by running the cf CLI command
cf service INSTANCE-NAME.
$ cf service myservice Service instance: myservice Service: super-db Bound apps: Tags: Plan: dedicated-vm Description: Dedicated Instance Documentation url: Dashboard: Last Operation Status: create failed Message: Instance provisioning failed: There was a problem completing your request. Please contact your operations team providing the following information: service: redis-acceptance, service-instance-guid: ae9e232c-0bd5-4684-af27-1b08b0c70089, broker-request-id: 63da3a35-24aa-4183-aec6-db8294506bac, task-id: 442, operation: create Started: 2017-03-13T10:16:55Z Updated: 2017-03-13T10:17:58Z
Use the information in the
Message field to debug further.
Provide this information to Pivotal Support when filing a ticket.
task-id field maps to the BOSH task ID.
For more information on a failed BOSH task, use the
bosh task TASK-ID.
broker-request-guid maps to the portion of the On-Demand Broker log
containing the failed step.
Access the broker log through your syslog aggregator, or access BOSH logs for
the broker by typing
bosh logs broker 0.
If you have more than one broker instance, repeat this process for each instance.
You might need to find the name, GUID, or other information about a service instance. To find this information, do the following:
Log into the space containing the instance or failed instance.
$ cf login
If you do not know the name of the service instance, run
cf servicesto see a listing of all service instances in the space. The service instances are listed in the
$ cf services Getting services in org my-org / space my-space as email@example.com... OK name service plan bound apps last operation my-instance p.mysql db-small create succeeded
To retrieve more information about a specific instance, run
cf service SERVICE-INSTANCE-NAME
To retrieve the GUID of the instance, run
cf service SERVICE-INSTANCE-NAME --guid
The GUID is useful for debugging.

Be sure to provide the error message from
cf service YOUR-SERVICE-INSTANCE.
To expedite troubleshooting, if possible, provide your service broker logs, service instance logs, and BOSH task output. Your cloud operator should be able to obtain these from your error message.
