Configuring Rancher Observer jobs
Using the Rancher Observer, you can define a full load job that will read data from Rancher through the REST API and generate a topology.
Before you begin
Important: The Rancher Observer supports the on-premises Rancher version 2.3.2 and API version 3.0.
Ensure you have the Rancher details to hand, such as the Rancher host IP, accessKey, secretKey and clusterId, before running the observer job.
The Rancher Observer supports a transient (one-off) Load job that loads all requested topology data through Rancher REST API to build the topology, and then exit.
You define and start the following job. You must edit the parameters in the configuration file before running this job.
Full Topology Upload job By default, Load jobs are one-off, transient jobs that do a full upload of all requested topology data as soon as they are triggered.
You can also run these jobs (again) manually from the Observer UI, or schedule them to run at set times when configuring them.
Enabling access to the URL routes

Encryption requirement: See the Configuring observer jobs security topic for more information.
| Parameter | Action | Details |
|---|---|---|
| Rancher Host IP | Enter the Rancher host IP address | Required |
| Rancher Access Key ID | Supply the Rancher access key | Required |
| Rancher Secret Access Key | Supply the Rancher secret key | Required |
| Rancher Cluster ID | Enter the cluster ID to be discovered | Required |
| Enable/Disable Secure Host Connection to Rancher's Host | Set to 'true' to secure the connection. Alternatively, set to 'false' to bypass secure host connection. | Required |
| Certificate | If enable_secure_host_connection is set to 'true', update the global secret with encrypted certificate information. See the relevant step here. | Optional |
| SSL truststore File | If enable_secure_host_connection is set to 'true', provide the JKS name, and the observer creates the JKS file | Optional |
| Password SSL truststore File | If enable_secure_host_connection is set to 'true', set the password to decrypt the HTTPS truststore file. | Required if enable_secure_host_connection is set to 'true'. You must supply the SSL truststore Password to decrypt the HTTPS truststore file. |
| Generate debug support file | Set this parameter to 'True' in order to capture the output of the next scheduled job run as a file. This file will be stored with an observer's log files and can be used to debug observer issues, for example at the request of your designated Support team, or while using a test environment. For one-off jobs (that is, Load jobs), this parameter reverts to 'False' after the next completed run. To examine the output produced, you can load the generated debug file using the File Observer. | Optional |
| Job schedule | Specify when the job runs | Optional. Load jobs only. |
| Observer job description | Enter additional information to describe the job | Optional |
