E-mailing log messages containing specific tags
If, like most sysadmins, you feel like you don't get enough e-mail, you'll be looking for a way to generate more. Another type of Puppet report is called tagmail. This will e-mail the log messages to any address you specify.
How to do it…
- Add
tagmailto the comma-separated list of reports inpuppet.conf:[master] reports = store,tagmail
- Add some tags and associated e-mail addresses in the file
/etc/puppet/tagmail.conf. For example, this line will e-mail all log messages to me:all: john@example.com
- When Puppet runs, you will get an e-mail that looks like the following:
From: report@cookbook.bitfieldconsulting.com Subject: Puppet Report for cookbook.bitfieldconsulting.com To: john@example.com Mon Jan 17 08:42:30 -0700 2011 //cookbook.bitfieldconsulting.com/Puppet (info): Caching catalog for cookbook.bitfieldconsulting.com Mon Jan 17 08:42:30 -0700 2011 //cookbook.bitfieldconsulting.com/Puppet (info): Applying configuration version '1295278949'
How it works…
Puppet looks at each line in tagmail.conf and sends any messages matching the tag to the e-mail address specified. The special tag all matches all messages. The tag err matches errors as shown in the following code snippet:
err: john@example.com
You can list as many rules as you like in the tagmail.conf file, and Puppet will send e-mails for all rules that match. In the following example, errors go to one address, and web server related messages go to another:
err: puppetmaster@example.com webserver: webteam@example.com
There's more…
The tagmail reports are a powerful feature which you may need to experiment with a bit so that you can get the most out of them. I have given a few tips to help you in the following text.
What are tags?
Tags are explained in more detail later in this book, but for reporting purposes, it's enough to know that a tag can be the name of a node or a class. For example, the tag webserver is matched if a machine includes the class webserver. You can also add a tag explicitly, using the tag function as follows:
class exim {
tag("email")
service { "exim4":
ensure => running,
enable => true,
}
}
Specifying multiple tags, or excluding tags
You can specify a comma-separated list of tags in tagmail.conf, and also exclude certain tags by using an exclamation point (!).
all, !webserver: puppetmaster@example.com
Sending reports to multiple e-mail addresses
You can send messages to multiple, comma-separated e-mail addresses as shown in the following code-snippet:
err: puppetmaster@example.com, sysadmin@example.com
