Description

Installs the Sumo Logic collector the way we do it at PagerDuty. Allows you to configure the sources to send up; works on Linux x86 and x86-64. Sets up a fully unattended installation and gets all your sources pushed up without you manually activating or pushing any buttons.

Requirements

Depends on the Opscode java cookbook which ensures you have a /usr/bin/java. Really that's all you need, so feel free to break that dependency if you have an alternative method of installing Java.

The cookbook grabs a Sumo Logic tarball from an http server. Sumo Logic provides you download links if you want to use those, but they're ephemeral, so I suggest hosting it on a local asset server.

Platform

• Tested on Ubuntu 10.04, 12.04, 14.04
• Tested on CentOS 5.11, 6.6, 7.0
• Will need extra work to run in Windows, Solaris.
• Tested under Chef 11.0.0, 11.16.4, and 12.1 under Ruby 2.1.5 and 2.2.0.

Attributes

See attributes/default.rb for default values.

• node[:sumologic][:rootdir] - The directory you want to house Sumo Logic collector in. It will sit in a subdirectory of the rootdir called 'sumocollector'.
• node[:sumologic][:disabled] - Set this if you need to disable the collector on this node for some reason.
• node[:sumologic][:custom_install] - Set this if you want to disable the default collector install on this node for some reason. This can be used if you need to install the collector in a custom manner. Default is false.
• node['sumologic']['api_timeout'] - Set a timeout for calls to the Sumologic API. Default is 60 seconds
• node[:sumologic][:collector][:version] - The version of the collector you want to install.
• node[:sumologic][:collector][:tarball] - The name of the tarball you're downloading, so the s.tar.gz in the above example.
• node[:sumologic][:collector][:checksum] - The md5sum of the tarball.
• node[:sumologic][:collector][:url] - The full URL you're downloading the collector from.
• node[:sumologic][:admin][:email] - The email of an admin user that will be invoked to perform unattended installs of collectors. See Sumo's article for more info: https://service.sumologic.com/ui/help/Unattended_Installation.htm
• node[:sumologic][:admin][:pass] - The password for the admin's email above.
• node[:sumologic][:log_sources][:default_category] - You can specify a category for any of your resources through the sumo_source definition (see below), but this allows you to provide a catch-all that's more descriptive than 'log'.
• node[:sumologic][:log_sources][:default_timezone] - If you have timezone parsing disabled or if there are no timezones in your log timestamps, input the timezone you want to default to (must match Sumo's dropdown list exactly). Otherwise will default to UTC.
• node[:sumologic][:log_sources][:force_timezone] - Set to true to force any timestamps parsed out of log files to this timezone, regardless of any timezone information they may carry.

Usage

Drop this cookbook with the default recipe onto your servers and you've got a collector running. Want some sources? Use the sumo_source definition provided to create them. Example:

sumo_source 'syslog' do
    path '/var/log/syslog'
    category 'syslog'  # optional, defaults to 'log' or the category attr.
    default_timezone 'UTC'  # optional, defaults to UTC or timezone attr.
    force_timezone true # optional, defaults to false or the force attr.
end

You may include this definition in any recipe; it will “do the right thing” and configure all of your sources before restarting sumologic. It will also correctly set the '-o' sumocollector parameter for a sumo restart to force the web interface to accept changes to your sources.

Helper Functions

Sumologic.collector_exists?(node_name, email, pass)

This checks whether or not a collector with the given name exists.

• node_name - name of the collector to be checked
• email - email to use againt the API
• pass - password for the email above

Changes

v0.0.2

• Broken off of PagerDuty's internal chef repo and released to the world with sane defaults.

v0.0.3

• Fixed upgrades to a newer sumocollector version.

v0.0.4

• Various cleanups re: string quoting.
• Workaround (-c) for Sumo Logic being incapable of reconfiguring sources correctly. The workaround is only moderately less idiotic than that, as it requires a logrotate invocation to work properly.
• Fix for collector not restarting if you haven't modified sources in between the last time the collector was disabled and now.
• Stop forcing a particular URL to work; users can now use whatever URL they please to store their Sumo tarballs.
