satellite-performance

What is satellite-performance

This project was started to run performance tests on Red Hat Satellite 6. It does the following activities:

• Satellite installation
• Uploads manifest, updates repo
• Concurrently syncs multiple repositories from repo server
• Creates lifecycle environments
• Creates capsules
• Concurrently syncronizes multiple capsules
• ..etc

It also provides a way to measure time for tests while capturing resources using collectd.

Ansible for satellite-performance

Ansible is used to perform most of the work. There are playbooks for:

• Installing satellite
• Installing capsule
• Registering containers as hosts to capsule
• Install katello-agent and run errata
• Sync content
• Puppet module update

Installation

Prerequisities

You need Ansible installed.

For some playbooks, you might need extra roles and collections installed:

$ ansible-galaxy role install -r requirements.yml
$ ansible-galaxy collection install -r requirements.yml

Configuration

1. Before running satellite-performance, check conf/satperf.yaml, and create conf/satperf.local.yaml and configure any overrides there (e.g. RHSM credentials, Satellite setup details etc).

2. Make sure that all hosts you are going to use have SSH certificate deployed for user root and private certificate is configured in your conf/satperf.local.yaml.

3. Save your Satellite manifest as conf/manifest.zip or elsewhere and configure path in your conf/satperf.local.yaml.

4. If you are going to use satperf to setup your docker hosts, pay special attention to their partitioning. There are few very simple pre-created roles like: playbooks/satellite/roles/docker-host-kvm-partitioning and .../docker-host-ec2-partitioning. Please choose one or create new one byt setting docker_host_partitioning in config to "kvm" or "ec2" or add new one and alter playbooks/satellite/docker-host.yaml

Usage

To prepare Docker hosts:

$ ansible-playbook --private-key conf/id_rsa -i conf/hosts.ini playbooks/docker/docker-host.yaml

To prepare Satellite:

$ ansible-playbook --private-key conf/id_rsa -i conf/hosts.ini playbooks/common/common.yaml
$ ansible-playbook --private-key conf/id_rsa -i conf/hosts.ini playbooks/satellite/satellite-capsule_common.yaml
$ ansible-playbook --private-key conf/id_rsa -i conf/hosts.ini playbooks/satellite/satellite_specific.yaml

To prepare Capsules:

$ ansible-playbook --private-key conf/id_rsa -i conf/hosts.ini playbooks/common/common.yaml
$ ansible-playbook --private-key conf/id_rsa -i conf/hosts.ini playbooks/satellite/satellite-capsule_common.yaml
$ ansible-playbook --private-key conf/id_rsa -i conf/hosts.ini playbooks/satellite/capsules_specific.yaml

To install Collectd:

$ ansible-playbook --private-key conf/id_rsa -i conf/hosts.ini playbooks/monitoring/collectd-generic.yaml --tags "satellite6"

...Replace "satellite6" with whatever machines you intend to install collectd on.

To install collectd->graphite dashboards:

$ ansible-playbook --private-key conf/id_rsa -i conf/hosts.ini playbooks/monitoring/dashboards-generic.yaml

If collectd fails to send metrics to your grafana instance

You might wanna check the selinux policies. Try one of the following to counter "Permission Denied" log statement:

# setsebool -P collectd_tcp_network_connect 1

OR

# audit2allow -a
# audit2allow -a -M collectd_t
# semodule -i collectd_t.pp

OR

# semanage permissive -a httpd_t

..or all.
