Support for increasing thread cache size in TCMalloc.

jangseon ryu authored 7 years ago

Currently TCMalloc's default tc size is 32MB.
This causes poor performance in ceph storage.
A new ceph_tcmalloc_tc_bytes option has been added
with a default of 128MB.

128 MB is default TC size at above jewel version.
and if we don't set this config,
osd daemon will running with 32 MB.
because 32MB is default size in TCmalloc 2.4 version.
32MB and 128MB are twice the performance difference.

Kolla-Ansible Overview

The Kolla-Ansible is a deliverable project separated from Kolla project.

Kolla-Ansible deploys OpenStack services and infrastructure components in Docker containers.

Kolla's mission statement is:

To provide production-ready containers and deployment tools for operating
OpenStack clouds.

Kolla is highly opinionated out of the box, but allows for complete customization. This permits operators with little experience to deploy OpenStack quickly and as experience grows modify the OpenStack configuration to suit the operator's exact requirements.

Getting Started

Learn about Kolla-Ansible by reading the documentation online docs.openstack.org.

Get started by reading the Developer Quickstart.

OpenStack services

Kolla-Ansible deploys containers for the following OpenStack projects:

Infrastructure components

Kolla-Ansible deploys containers for the following infrastructure components:

Ceph implementation for Cinder, Glance and Nova.
Collectd, Telegraf, InfluxDB, and Grafana for performance monitoring.
Elasticsearch and Kibana to search, analyze, and visualize log messages.
Etcd a distributed reliable key-value store.
Fluentd as an open source data collector for unified logging layer.
HAProxy and Keepalived for high availability of services and their endpoints.
Kafka A distributed streaming platform.
MariaDB and Galera Cluster for highly available MySQL databases.
Memcached a distributed memory object caching system.
MongoDB as a database backend for Ceilometer and Gnocchi.
Open vSwitch and Linuxbridge backends for Neutron.
RabbitMQ as a messaging backend for communication between services.

Directories

ansible - Contains Ansible playbooks to deploy OpenStack services and infrastructure components in Docker containers.
contrib - Contains demos scenarios for Heat and Murano and a development environment for Vagrant
doc - Contains documentation.
etc - Contains a reference etc directory structure which requires configuration of a small number of configuration variables to achieve a working All-in-One (AIO) deployment.
specs - Contains the Kolla-Ansible communities key arguments about architectural shifts in the code base.
tests - Contains functional testing tools.
tools - Contains tools for interacting with Kolla-Ansible.
