Overview

The gnocchi module is a part of OpenStack, an effort by the OpenStack infrastructure team to provide continuous integration testing and code review for OpenStack and OpenStack community projects as part of the core software. The module itself is used to flexibly configure and manage the management service for OpenStack.

Module Description

Setup

What the gnocchi module affects:

  • Gnocchi, the HTTP API to store metrics and index resources for OpenStack (OpenStack Datapoint Service).

Installing gnocchi

puppet module install openstack/gnocchi

Implementation

gnocchi

gnocchi is a combination of Puppet manifest and ruby code to delivery configuration and extra functionality through types and providers.

Types

gnocchi_config

The gnocchi_config provider is a children of the ini_setting provider. It allows one to write an entry in the /etc/gnocchi/gnocchi.conf file.

gnocchi_config { 'DEFAULT/debug' :
  value => true,
}

This will write debug=true in the [DEFAULT] section.

name

Section/setting name to manage from gnocchi.conf

value

The value of the setting to be defined.

secret

Whether to hide the value from Puppet logs. Defaults to false.

ensure_absent_val

If value is equal to ensure_absent_val then the resource will behave as if ensure => absent was specified. Defaults to <SERVICE DEFAULT>

Limitations

Load balancing Gnocchi MySQL with HAProxy

Issue

MySQL client/server interaction causes an issue where the HAProxy server will keep a connection in TIME_WAIT. When Gnocchi is processing data it will generate a lot of connections to MySQL and exhaust all available tcp ports for a given IP address. If the HAProxy VIP is shared with other components, this can cause them to be unavailable too. Tuning of HAProxy instance is essential when using Gnocchi with a MySQL behind an HAProxy.

The sysctl parameters need tuning.

  • net.ipv4.tcp_tw_reuse = 1
  • net.core.somaxconn = 4096
  • net.ipv4.tcp_max_syn_backlog = 60000

Additionally, HAProxy can be configured to use different source IP addresses on each backend to help further mitigate the issue.
