It is critical to monitor these core service nodes, and to always make sure these nodes have enough resources for new customers and workers as they are on-boarded. These core services nodes are dedicated to the following services: If these nodes become overly taxed, you can add another node dedicated to the core services in the cluster.

Allocating more resources than necessary to these nodes allows you to further scale workers in the future. As a result, it is essential that these services are clustered to handle failovers.īecause these core services are critical, ScienceLogic recommends that you initially allocate a fairly large amount of resources to these services. These core PowerFlow services are shared by all workers and customers. Core Service Nodesįor a multi-tenant deployment, ScienceLogic recommends that you dedicate at least three nodes to the core PowerFlow services. After the initial High Availability (HA) core services are deployed, the multi-tenant environment differs in the deployment and placement of workers and use of custom queues. The following sections describe how to deploy PowerFlow in a multi-tenant environment.

Specify the configuration object to use in PowerFlow for this SL1 instance.

Modify the IS_PASSTHROUGH dictionary with "queue" setting.

Modify the Run Book Automations in SL1 to trigger the integration to run on the queue for this customer:.

Correlation queue manager running on the catchup queue.

Schedule the required PowerFlow integrations:.

Update the new steprunner user_queues environment variable to only listen on the desired queues.

Update the new steprunner deploy constraints to deploy only to the designated labels.

Update the new steprunner hostnames to indicate who the steprunner works for.

Add two steprunner services for each customer, one for real-time eventing, and one for backlogged events, labeled based on the organization name: acme and acme-catchups.

Update the docker-compose.yml file on a core node:.

Label the worker node or nodes specifically for the customer.

Deploy and cluster the worker node or nodes for the customer.

The configuration object includes the SL1 IP address, the ServiceNow user and domain, and other related information. Create the PowerFlow configuration object for the new PowerFlow systems.Deploy and cluster the initial High Availability stack.
