Client software for the Apocalypse Server

Apocalypse Client

Apocalypse Client is a ruby gem that can be installed on a remote server.

Installation

Apocalypse Client currently focusses on Debian/Ubuntu systems only.

There is only one dependency to the operating system, namely the sysstat package. This package is used to gather information about disk utilisation and performance.

sudo apt-get install sysstat

Next install the ruby gem.

sudo gem install apocalypse-client

once installed run the install|now command apocalypse-client now

This will send metrics data every minute to your Apocalypse server. If you require different intervals, refer to man 5 crontab for details on how to schedule reporting.

If an error occurs cron will try to notify you by email. This depends on how your systems cron is configured.

Choosing a proper hostid

Choosing a proper hostid is important, because it can be arbitrarily chosen. There are several options:

• Use the format appname-role-number. E.g. ariejannet-db-01 or reddis-memcached-42.
• IP Address of the server, this guarantees some level of uniqueness

Note: at this time, there is not convention for picking hostids. However, the first method is likely to become the convention and will allow logical grouping of servers by role and application.

apocalypse-client's Issues

Store apocalypse-client configuration centrally

For example in /etc/apocalyse.yml

cronjob named apocalyse (-p)

This should be 'apocalypse'

Older clients spam errors

On an older debian system (Debian 4.0)

 Bcast:[0-9]1.[0-9]1.[0-9]1.[0-9]3: No such file or directory

Somethings off with the client getting networking info.

'now' and 'install' should run 'check' first.

Just to be sure all dependencies are met.

Reporter doesn't see LVM volumes

The are just ignored, giving a false sense of security.

$ df -h

/dev/sda1             228M   45M  172M  21% /boot

/boot is reported correctly, /dev/mapper/asdf-root is not.
