Description Matt Wringe 2017-11-15 19:46:38 UTC

There is a property value in Heapster which we can use to increase the number of connections between Heapster and Hawkular Metrics. This can increase performance.

Right now the only way to configure this is to make the change in the Heapster template. We should have this be configurable in ansible inventory file.

Default value for concurrencyLimit default is 5, and it can be configured by parameter openshift_metrics_heapster_concurrency_limit.

Sanity testing is passed.

# oc get po heapster-7k2fb -o yaml | grep concurrencyLimit
    - --sink=hawkular:https://hawkular-metrics:443?tenant=_system&labelToTenant=pod_namespace&labelNodeId=nodename&caCert=/hawkular-metrics-certs/tls.crt&user=%username%&pass=%password%&filter=label(container_name:^system.slice.*|^user.slice)&concurrencyLimit=5
