Configuring collectd

Set up an external collectd server

If you haven't already set up an external collectd server, you will need to do so before enabling collectd forwarding on your GitHub Enterprise Server instance. Your collectd server must be running collectd version 5.x or higher.

1. Log into your collectd server.
2. Create or edit the collectd configuration file to load the network plugin and populate the server and port directives with the proper values. On most distributions, this is located at /etc/collectd/collectd.conf

An example collectd.conf to run a collectd server:

LoadPlugin network
...
...
<Plugin network>
    Listen "0.0.0.0" "25826"
</Plugin>

Enable collectd forwarding on GitHub Enterprise

By default, collectd forwarding is disabled on GitHub Enterprise. Follow the steps below to enable and configure collectd forwarding:

1. Em uma conta administrativa no GitHub Enterprise Server, no canto superior direito de qualquer página, clique em .

   

2. Se você ainda não estiver na página "Administração do site", no canto superior esquerdo, clique em Administração do site.

   

3. Na barra lateral �  esquerda, clique em Console de Gerenciamento .

4. Below the log forwarding settings, select Enable collectd forwarding.

5. In the Server address field, type the address of the collectd server to which you'd like to forward GitHub Enterprise appliance statistics.

6. In the Port field, type the port used to connect to the collectd server. (Defaults to 25826)

7. In the Cryptographic setup dropdown menu, select the security level of communications with the collectd server. (None, signed packets, or encrypted packets.)

8. Na barra lateral esquerda, clique em Salvar configurações.

   

   Observação: se você salvar as configurações no Console de Gerenciamento, isso reiniciará os serviços do sistema, o que poderá resultar em tempo de inatividade visível pelo usuário.

9. Aguarde a conclusão da execução de suas configurações.

   

Exporting collectd data with ghe-export-graphs

The command-line tool ghe-export-graphs will export the data that collectd stores in RRD databases. This command turns the data into XML and exports it into a single tarball (.tgz).

Its primary use is to provide the Suporte do GitHub Enterprise team with data about a VM's performance, without the need for downloading a full Support Bundle. It shouldn't be included in your regular backup exports and there is no import counterpart. If you contact Suporte do GitHub Enterprise, we may ask for this data to assist with troubleshooting.

Usage

ssh -p 122 admin@[hostname] -- 'ghe-export-graphs' && scp -P 122 admin@[hostname]:~/graphs.tar.gz .

Troubleshooting

Central collectd server receives no data

GitHub Enterprise ships with collectd version 5.x. collectd 5.x is not backwards compatible with the 4.x release series. Your central collectd server needs to be at least version 5.x to accept data sent from your GitHub Enterprise Server instance.
